INTRODUCTION
‘Plaintiff Pure Fishing, Inc. (“PFI”) is the owner of United States Patent No. 5,749,214
(‘214 patent). The ‘214 patent, in general terms, describes and claims a process for increasing
the tenacity of a braided fishing line made from gel spun polyolefin (“GSP”) material, by
stretching the braided line under heat. PFI alleges that certain Sufix brand fishing lines sold by
Defendant Normark Corporation (“Normark”) are manufactured for Normark by Yao I Fabric
Co., Ltd. (“Yao I”) using a process that infringes claims 1, 4, and 5 of PFI’s ‘214 patent. PFI
employee Roger Cook is listed as the sole inventor of the ‘214 patent.
Normark filed a motion for summary judgment seeking a ruling that the ‘214 patent is
invalid as a matter of law on four grounds:
1.
Normark argues that the asserted claims of the ‘214 patent are invalid under 35
U.S.C. § 102(f) because Roger Cook did not invent the subject matter of the patent claims.
2.
Normark argues that the asserted claims of the ‘214 patent are invalid under 35
U.S.C. § 102(b), because PFI used the claimed process to make commercial products, referred to
by the parties as the 1995 Fireline Fused products, more than one year before it filed the
application that led to the ‘214 patent.
3.
Normark argues that the asserted claims of the ‘214 patent are invalid under 35
U.S.C. § 102(b) because AlliedSignal’s Canadian Patent No. 1,276,065 (“Dunbar”) anticipates
the asserted claims.
4.
Normark argues that the asserted claims are invalid as obvious under 35 U.S.C. §
103.
Normark also seeks summary judgment on three additional grounds: (1) Normark seeks
partial summary judgment of non-infringement, arguing that the accused products manufactured
for Normark beginning in June 2010 do not literally infringe the asserted claims; (2) Normark
seeks summary judgment on PFI’s claim for willful infringement, arguing that Normark has
credible defenses and summary judgment is therefore warranted under In re Seagate Tech., LLC,
497 F.3d 1360, 1371 (Fed. Cir. 2007) (en banc); and (3) Normark seeks summary judgment on
PFI’s damages claim, asking the court to rule that PFI has no admissible evidence of damages.
Normark also moved in limine to exclude the testimony of PFI’s damages expert, Hugh Penny.
PFI filed two motions for summary judgment. First, PFI seeks partial summary judgment
on the question of infringement, arguing that the manufacturing process used by Yao I before
June 2010 literally infringed the asserted claims. Second, PFI seeks summary judgment on
Normark’s inequitable conduct counterclaim, arguing that there are no genuine issues of material
fact regarding materiality and intent.
After filing these motions, the parties filed a stipulation that resolved the infringement
issues. Dkt. No. 217. The parties’ stipulation made moot PFI’s motion for partial summary
judgment as to infringement, Dkt. No. 216, and also made moot that part of Normark’s motion
for summary judgment seeking partial summary judgment on the issue of infringement (Part VIII
of the “Statement of Facts” and Part VI of the “Argument” sections of Dkt. No. 211-1).
2
The court grants Normark’s motion for summary judgment in part. The court finds that
claims 1, 4, and 5 of the ‘214 patent are invalid as a matter of law for three reasons. First, the
asserted claims are invalid under 35 U.S.C. § 102(f), because Roger Cook is not the inventor of
the asserted claims. Second, the asserted claims are invalid under 35 U.S.C. § 102(b), because
PFI used the claimed process to make the 1995 Fireline Fused products more than one year
before it filed the application that led to the ‘214 patent. Third, the asserted claims are also
invalid as obvious under 35 U.S.C. § 103. The court denies Normark’s motion for summary
judgment that the Dunbar patent anticipates the asserted claims.
Based on these rulings, the court holds that the issue of willful infringement is moot; in
the alternative the court holds that Normark is entitled to summary judgment on the issue of
willfulness because PFI cannot satisfy the objective prong of the Seagate test. The court does
not reach Normark’s motion for summary judgment on the issue of damages or Normark’s
motion to exclude the testimony of Hugh Penny, because those motions are moot in light of the
court’s ruling on invalidity. Finally, the court denies PFI’s motion for summary judgment on
Normark’s inequitable conduct counterclaim.
The court issued an oral ruling via telephone on October 5, 2012. Pursuant to Local Rule
7.10, the court requested that counsel for Normark draft a proposed order, and provided detailed
instructions both as to the content and procedures for submission and comment. The court
allowed a period for PFI to comment on the proposed order. The court now enters this Order
after independent review and consideration of the comments made by the parties.

STATEMENT OF RELEVANT FACTS
I.
THE PARTIES
PFI is an Iowa corporation with operations in Iowa and South Carolina.
PFI was
formerly known as Berkley, Inc. Normark is a Minnesota corporation and a subsidiary of Rapala
VMC Corporation. In June 2008, Rapala VMC acquired the rights to the Sufix brand from
Yao I, and Normark began selling Sufix lines in the United States. Dkt. No. 211-65 at 1, ¶¶ 3-4.
II.
THE FISHING LINE MARKET AND SUPERLINE PRODUCTS
The parties’ submissions indicate that there are three categories of fishing line:
monofilament, fluorocarbon, and “Superlines.” The Superlines are made from very strong
materials, either the GSP materials that are a subject of the ‘214 patent, or Kevlar. The first
Superlines were introduced by 1993. Kavesh Exs. 17, 18 (Dkt. Nos. 211-19 and 211-20). That
spring, a professional bass fisherman won a tournament using a Superline, creating considerable
industry buzz. Kavesh Ex. 18, p. 47 (Dkt. No. 211-20 at 4). By fall 1993, many companies had
introduced braided GSP Superlines. Id., p. 50 (Dkt. No. 211-20 at 7); Foote dep. at 11-12, 2829 (Dkt. No. 211-30 at 3-6).
Most Superlines are made from GSP. Kavesh Exs. 17, 18 (Dkt. Nos. 211-19 and 21120). AlliedSignal, Inc., now Honeywell International, Inc. (“AlliedSignal”), and DSM (formerly
Dutch State Mines) supply the GSP used to make Superlines. AlliedSignal’s product is called
Spectra, and DSM’s is called Dyneema. The 1993 Superlines were very strong, much thinner
than comparable monofilaments, and very sensitive (because the material has little stretch, a
fisherman can “feel” the fish taking the hook). Kavesh Ex. 18 at pp. 47-48 (Dkt. No. 211-20 at
4-5). SafariLand’s Spiderwire product was the early market leader, achieving millions of dollars
in sales. van Gorp dep. at 208-09 (Dkt. No. 211-33 at 80-81). PFI had two early Superline
products, Gorilla Braid and Ultra Max, and PFI eventually acquired the Spiderwire brand as
4
well. Meyer 30(b)(6) dep. at 10 (Dkt. No. 211-32 at 3). According to the parties, the 1993
Superlines were not heat stretched after braiding.
PFI introduced its Fireline Fused product (“1995 Fireline Fused”) in 1995. Reynolds Ex.
20 (Dkt. No. 211-45). The 1995 Fireline Fused was “fused”, meaning the braided yarns were at
least partially melted together.
Normark contends that the 1995 Fireline Fused product
invalidates claims 1, 4, and 5, while PFI disputes that contention. According to PFI, it did not
introduce a product covered by the ‘214 patent until 1999. Reynolds Ex. 13 (Dkt. No. 211-38).
PFI currently sells several brands that are covered by the ‘214 patent. Reynolds Ex. 12, p. 2
(Dkt. No. 211-37 at 3). PFI also sells two braided Superlines that are not heat stretched. Meyer
dep. at p. 40-41 (Dkt. No. 211-31 at 3-4).
III.
THE ‘214 PATENT
PFI applied for the ‘214 patent on October 4, 1996, and it issued on May 12, 1998. The
‘214 patent claims a process for increasing tenacity in a braided GSP fishing line, by stretching
the braided line under heat. “Tenacity” is essentially strength per unit area. The patent states
that “DYNEEMA [GSP] yarn can be used to make braided fishing lines exhibiting low stretch as
well as high toughness,” but notes that a braid’s strength is not equal to the sum of the strength
of the braid’s yarns because of inefficiency introduced by the braiding process:
Braiding, however, introduces its own form of vulnerability into
the resulting line because the braid strength is generally not the
sum or average of either the individual yarn strengths or the
individual filament strengths of the multifilament yarn. One
explanation is that most braiding equipment does not impart a
uniform load to all yarns or filaments in the braid. The braid
pattern inherently leaves gaps between the yarns and filaments,
and will lay the yarns in a pattern with a particular relative angle.
As stress is applied, filaments with the highest as-braided stress
will bear substantial load alone until they either fail or elongate
sufficiently for the remaining filaments to contribute to the loadbearing burden. With low stretch materials like the gel spun
polyolefins, the most stressed filaments will generally break before
5
sufficient elongation has occurred to allow the remaining filaments
to substantially bear the stress. The result is a reduced efficiency
in the strength of the line or a weakened line (due to broken
filaments) after stress.
Reynolds Ex. 1, col. 1, l. 48-64 (Dkt. No. 211-26). This efficiency problem is the only one noted
by the ‘214 patent. The patent states that heat stretching the braid addresses this problem by
distributing “the load-bearing function more evenly among filaments and yarns in the braid.”
Id., col. 2, l. 18-19.
The Ryan Patent (U.S. Patent No. 5,351,373) issued two years before the ‘214
application. Ryan describes heat stretching synthetic fishing lines to address the same efficiency
problem described in the ‘214 patent, and refers to that problem as “translational efficiency.”
Ryan Col. 1, l. 18-49 (Dkt. No. 211-8). Roger Cook and PFI’s expert, Egbert van Gorp,
conceded that the Ryan Patent describes using heat stretching to solve the same translational
efficiency problems of a braided line described by the ‘214 patent. Cook dep. at 40-41 (Dkt. No.
211-29 at 18-19); van Gorp dep. at 59-61 (Dkt. No. 211-33 at 7-9).
As noted above, PFI claims that Normark’s manufacturer, Yao I, has manufactured
certain Sufix fishing line products using a process that infringes Claims 1, 4, and 5 of the ‘214
patent. These claims recite:
Claim 1: A process for increasing tenacity in a twisted or braided
fishing line made of gel spun polyolefin yarns, said process
comprising stretching a braided or twisted line of 3-64 gel spun
polyolefin yarns, wherein each yarn is within the range from about
20 denier to about 1000 denier, at a temperature within the range
from about 110°C. to about 150°C. and at a total draw ratio within
the range from about 1.0 to about 2.0.
Claim 4: A process according to claim 1 wherein said stretching
comprises stretching said line at a total draw ratio within the range
from about 1.05 to about 1.5.
6
Claim 5: A process according to claim 4 wherein said stretching
comprises stretching said line at a total draw ratio within the range
from about 1.1 to about 1.4.
IV.
GLOSSARY OF KEY TERMS
Several terms used in the patent are important to understanding the ‘214 patent and the
issues in this case. Those terms are defined here:
·
Break Load Strength (Break Load): The force it takes to break a
line. Describing a fishing line as a “20 lb. test line” means it
should not break until at least 20 pounds of force is applied.
Kavesh ¶ 5 (Dkt. No. 211-2 at 2).
·
Denier: The weight in grams of 9000 meters of material. For a
given material, the larger the denier, the thicker the line (i.e. the
greater the cross-sectional area). Kavesh ¶ 6 (Dkt. No. 211-2 at 2);
Reynolds Ex. 1, Col. 3, l. 60 (Dkt. No. 211-26).
·
Tenacity: Break load divided by denier, typically expressed as
grams per denier (gpd). Kavesh ¶ 7 (Dkt. No. 211-2 at 2);
Reynolds Ex. 1 , col. 1, l. 62 (Dkt. No. 211-26). Because it is a
ratio, stretching can increase tenacity even if break load strength
decreases, as long as the denier decreases more than the break load
decreases. Kavesh ¶ 7 (Dkt. No. 211-2 at 2).
·
Draw Ratio: The ‘214 patent defines draw ratio as “the ratio of the
output velocity to the input velocity of rollers acting on the line.”
Normark’s expert, Dr. Sheldon Kavesh, explained that the ‘214
patent’s definition describes a nominal draw ratio, as it does not
take slippage into account; an “effective draw ratio” is the ratio of
the denier of the line before drawing to the denier after drawing.
Kavesh ¶ 8 (Dkt. No. 211-2 at 2).
·
Total Draw Ratio: The product of individual draw ratios in a
multi-stage process, which is calculated by multiplying the
individual draw ratios. Reynolds Ex. 1, col. 3, l. 58-60 (Dkt. No.
211-26).
·
Yarn: Defined by the ‘214 patent to include “fiber, multifilament
assembly, or tow.” Reynolds Ex. 1, col. 3, l. 44-45 (Dkt. No. 21126). Yarn is also the term AlliedSignal and DSM use to describe
their GSP Spectra and Dyneema products. Kavesh ¶ 10 (Dkt. No.
211-2 at 2-3). Each yarn is made up of multiple filaments, which
are the smallest units. Id.; see also Reynolds Ex. 1, col. 3, l. 46
(Dkt. No. 211-26).

V.
THE PRIOR ART
Normark submitted evidence, which PFI did not dispute, establishing that the use of heat
stretching to increase tenacity has been known for decades. Kavesh ¶ 11 (Dkt. No. 211-2 at 3).
Before PFI’s patent, DSM and AlliedSignal used heat stretching to increase tenacity and reduce
the denier of their Dyneema and Spectra yarns. Kavesh ¶ 12 (Dkt. No. 211-2 at 3). The use of
heat stretching to improve braided structures, including braided fishing lines made from
synthetic materials, was also well known before the ‘214 patent. Kavesh ¶¶ 14-19 (Dkt. No.
211-2 at 3-4). Before the ‘214 patent, PFI itself heat stretched both its nylon monofilament
fishing lines and its braided Dacron fishing lines. Cook dep. at 79-80 (Dkt. No. 211-29 at 2526); Foote dep. at 54-55 (Dkt. No. 211-30 at 10-11). Two prior art references merit discussion:
1) DSM’s Hogenboom patent, and 2) AlliedSignal’s Dunbar patent.
A.
DSM’s Hogenboom Patent
DSM’s Patent No. 5,176,862 (“Hogenboom”) issued January 5, 1993.
Hogenboom
describes heat stretching a GSP rope to increase tenacity. Hogenboom defines “rope” as “rope,
cord, cable, string and similar structures.” Kavesh Ex. 5, col. 1, l. 10-12 (Dkt. No. 211-7).
Hogenboom teaches heat-stretching parameters that are within the ranges claimed by the ‘214
patent
a 140°C temperature and 5-23% elongation percentages. Id., Examples II, III, IV, XI
and IX; RC 167-68. Hogenboom’s elongation percentages of 5% and 23% are the same as draw
ratios of 1.05 and 1.23, and thus are within the scope of the draw ratios claimed in claims 1, 4,
and 5 of the ‘214 patent. Cook dep. at 166-167, 206-07 (Dkt. No. 211-29 at 39-40, 49-50).
Though Hogenboom’s teachings are broadly applicable to “string,” PFI notes that
Hogenboom’s examples stretch rope, while the ‘214 patent claims “fishing line.” Hogenboom
heat stretched a 425,000 denier rope. Cook dep. at 169-70 (Dkt. No. 211-29 at 42-43). Claim 1
of the ‘214 patent claims heat stretching a fishing line of up to 64,000 denier.
8
Cook testified that it would be easier to heat stretch his claimed fishing line than
Hogenboom’s rope. Cook also testified that, once it is known that one could use heat stretching
to increase the tenacity of a rope, the use of heat stretching to increase the tenacity of a braided
fishing line is an expected result:
Q. Now, back to this question of Hogenboom’s disclosure of
stretching the rope and your disclosure of stretching a fishing line,
albeit a pretty darn big one. Would you expect there to be any
I’m trying to think of the right way to ask this. Using heat to
stretch the fishing line is easier than using heat to stretch the rope;
right? Because of the heat transfer issue?
A. Yes.
Q. So one would expect once you know that you can heat stretch a
rope to increase tenacity that you could heat stretch a braided
fishing line to increase tenacity you would expect that; correct?
A. Yes.
Cook dep. at 174 (Dkt. No. 211-29 at 44).
PFI’s expert, Egbert van Gorp, agrees with Cook regarding Hogenboom, and also agrees
that it would be an “expected result” to use heat stretching to increase tenacity. van Gorp dep. at
144-46 (Dkt. No. 211-33 at 55-57), van Gorp dep. at 55-63, 74-75 (Dkt. No. 211-33 at 3-11, 2122).
Van Gorp testified that it was known from Hogenboom (and from the Ryan patent
discussed above in Part III) that one could achieve an increased break load, and therefore
increase tenacity, by using heat stretching to address braiding inefficiencies. van Gorp dep. at
58-61 (Dkt. No. 211-33 at 6-9). According to van Gorp, this expected result occurs during the
early stage of drawing, as the stretching process “pulls” the yarns to more evenly distribute the
load. van Gorp dep. at 58 (Dkt. No. 211-33 at 6).
Van Gorp created a graph, based on the ‘214 patent examples, showing a significant increase in
the break load and tenacity up to a draw ratio of between 1.1 and 1.2. Reynolds Ex. 11, p. 2
9
(Dkt. No. 211-36 at 3); see van Gorp dep. at 63-70 (explaining graph) (Dkt. No. 211-33 at 1118). The graph is reproduced below.
According to van Gorp, the increase in tenacity at this initial stretching stage is an expected
result that “everybody skilled in the art knew.” van Gorp dep. at 72-74, 141 (Dkt. No. 211-33 at
19-21, 54).
Van Gorp also testified that, in his opinion, the ‘214’s ability to continue to increase
tenacity past that initial stage of drawing was new and not obvious. van Gorp dep. at 76-82, 135
(Dkt. No. 211-33 at 23-29, 53). The ‘214 patent’s claims, however, cover a broad range of draw
10
ratios, including this initial stage of drawing (including the lowest possible draw ratio, 1.01).
See Claim 1.
Van Gorp’s testimony on this point is as follows:
Q. In your report on Page 7, this is Exhibit 56 now, I wanted to
ask you about the fourth paragraph of the report, and specifically
the first sentence you say: In the view of a person skilled in the art
at the time the invention was made, it could be expected that also
with braided fishing lines, the break load could be increased
initially. Do you see that sentence in your report?
A. Yes.
Q. Can you explain to me what you mean by that?
A. Given, for instance, the teaching of the Hogenboom patent, if
you have a braided structure, there is
you are losing strength in
the sense that there is translational efficiency, and by drawing or
stretching a braided structure, you therefore can expect that the
strength will go up.
Q. And you can expect that tenacity will go up?
A. Because the denier also will go down, it will go up
tenacity will go up.
the
* * *
Q. And what you are saying is by stretching the braid, this fouryarn braid that we are positing, you could expect to increase the
strength of the braid because you are basically pulling some of that
inefficiency to distribute the load more evenly across those yarns,
correct?
A. Yes.
Q. And that was something that was known before the Cook
patent?
A. That is the teaching of the Hogenboom patent also, so, yeah.
van Gorp dep. at 55-59 (Dkt. No. 211-33 at 3-7). Van Gorp also testified that the Ryan patent
teaches using heat stretching to increase translational efficiency (and therefore tenacity),
explaining that that was an “expected result” true for “any kind of line.” van Gorp dep. at 60-63
11
(Dkt. No. 211-33 at 8-11). Van Gorp further stated that “if you heat stretch a braided structure
made of Dyneema, you are going to get an increase in the break load at some initial phase of
drawing,” and that this was an “expected result” in light of Hogenboom or Ryan. van Gorp dep.
at 74-75 (Dkt. No. 211-33 at 21-22).
B.
AlliedSignal’s Dunbar Patent
AlliedSignal’s Dunbar patent, which Normark contends anticipates the asserted claims of
the ‘214 patent, describes heat stretching braided GSP yarns to increase tenacity. Dunbar’s
Example 7 describes heat stretching an 8-yarn GSP braid at 140.5°C, at draw ratios of 1.16-1.33,
to increase tenacity by 20-35%. The starting yarn denier is 1190. Kavesh ¶ 21 (Dkt. No. 211-2
at 4-5) and Ex. 7, p. 8-9, 17 (Dkt. No. 211-9 at 11-12, 20).
PFI argues that there are three distinctions between Dunbar Example 7 and claims 1, 4,
and 5 of the ‘214 patent. First, PFI notes that the starting denier of the yarns in Example 7 is
1190, greater than the “about 1,000” limitation for the yarns claimed in the ‘214 patent. van
Gorp dep. at 125-26 (Dkt. No. 211-33 at 46-47), Cook dep. at 177-79 (Dkt. No. 211-29 at 4547). Second, PFI argues that the ‘214 patent claims are limited to what its expert calls a “fullydrawn” yarn, which he defines as having a tenacity of 30 gpd or greater. van Gorp dep. at 79
(Dkt. No. 211-33 at 26). Third, PFI argues that the term “fishing line” in claim 1’s preamble is a
claim limitation. PFI and its expert further contend that even though Claim 1 describes a 64 yarn
by 1000 denier braid, such a braid would not be a “fishing line,” van Gorp dep. at 113 (Dkt. No.
211-33 at 39), and that the “fishing line” of the ‘214 patent claims should be limited to
recreational fishing lines with a maximum break load of 250 lbs. van Gorp dep. at 243-46 (Dkt.
No. 211-33 at 83-86). Based on that definition, PFI contends that Dunbar’s Example 7 does not
result in a “fishing line” and thus differs from the ‘214 patent claims.
12
With respect to the yarn denier limitation, Normark argues that the claims are not limited
to the “starting denier” of the yarn. Normark’s expert Dr. Kavesh testified that Dunbar Example
7 discloses heat stretching with yarn deniers at and below 1000 denier within the parameters of
claims 1, 4, and 5, because the yarn denier reduces below 1000 during the process. Kavesh ¶ 23
(Dkt. No. 211-2 at 5-6).
PFI and its expert dispute Dr. Kavesh’s argument, arguing that
interpreting the ‘214 patent’s claims to reach a process in which yarns are reduced to 1000
denier at any point in the process would distort the meaning of the claims. Dkt. No. 244 at 28-29
(pp. 23-24).
Concerning the “fully-drawn yarns” issue, Normark points out that the ‘214 patent claims
and specification do not use the term “fully-drawn yarns.” van Gorp dep. at 85 (Dkt. No. 211-33
at 31). The ‘214 patent also states that the yarns of the invention have “a tenacity of at least 15
g/ denier,” below van Gorp’s “fully-drawn” definition. Reynolds Ex. 1, col. 2, l. 38-39 (Dkt. No.
211-26). Normark notes that Dunbar Example 7’s yarn is similar, as it has a 29 gpd tenacity,
Kavesh Ex. 7, p. 17 (Dkt. No. 211-9 at 20), and also notes that Dunbar discloses other yarns with
deniers below 1000 and tenacities above 30 gpd, on the same page of the Dunbar patent as
Example 7. Id. PFI’s expert van Gorp concedes that, if one substitutes one of those yarns,
Example 7 would then match the ‘214 patent claims. van Gorp dep. at 129-131 (Dkt. No. 21133 at 50-52).
Finally, with respect to PFI’s “fishing line” argument, Normark’s primary response is
that the claim itself defines the claimed braided line as having up to 64 yarns of up to “about
1,000” denier each. Normark also points to inconsistencies in van Gorp’s testimony and his
inability to define specific yarn and denier parameters for the claim. See Dkt. No. 211-1 at 1516, 33 (pp. 9-10, 27).

VI.
EVIDENCE CONCERNING NORMARK’S ARGUMENT THAT COOK IS NOT
THE TRUE INVENTOR
PFI’s interrogatory answers state that Cook conceived the invention claimed in the ‘214
patent claims at least as early as October 5, 1994. Reynolds Exs. 13-18 (Dkt. Nos. 211-38
through 211-43). In his deposition, Roger Cook testified to the same conception date: October
5, 1994. Cook dep. at 10-11, 32-34 (Dkt. No. 211-29 at 3-4, 12-14).
Cook’s notebook corroborates the October 5, 1994 conception date. The notebook has a
page labeled “START POST DRAW.” The next entry reflects Cook’s heat stretching of a
Gorilla Braid on October 5, 1994. Reynolds Ex. 26 (Dkt. No. 211-51) and Cook dep. at 33-35
(Dkt. No. 211-29 at 13-15). Cook’s October 5, 1994 heat stretching work matches the ‘214
claims, as his first entry uses a draw ratio of 1.35 and a temperature of 130°C, and notes an
increase in tenacity. Reynolds Ex. 26 (Dkt. No. 211-51); Cook dep. at 108-109 (Dkt. No. 211-29
at 36-37). Cook testified that October 5, 1994 was the first time he heat stretched braided GSP
lines. Cook dep. at 108-109, 33-35 (Dkt. No. 211-29 at 36-37, 13-15). Cook testified further
that his October 5, 1994 notebook entry reflects his “documented record of the first [ ] drawing
experiments begun on the super line” and “the date that I began to work on that project and to
develop data and information that went into the [‘214] patent.” Cook dep. at 34 (Dkt. No. 21129 at 14); see Cook dep. at 33-35 (Dkt. No. 211-29 at 13-15).
Normark argues that the evidence shows that this October 5, 1994 conception did not
come from Roger Cook. Both DSM and AlliedSignal recommended heat stretching to PFI, and
performed heat stretching on PFI’s braided fishing lines, before Cook’s conception date.
According to Normark, Cook’s claimed invention was derived from DSM’s recommendations to
Cook’s colleague, Dan Foote. The evidence related to this issue is summarized below.
14
Roger Cook testified that Dan Foote had responsibility for PFI’s Superline products in
1994. Cook dep. at 64, 95-96 (Dkt. No. 211-29 at 24, 29-30). At that time, Foote was the main
person working to improve PFI’s Superline products, and Cook’s work focused on coatings and
assisting Foote with some ideas about heat relaxation, a process distinct from heat drawing.1
Cook dep. at 95-96 (Dkt. No. 211-29 at 29-30).
Foote set up a meeting with AlliedSignal for August 18, 1994, to discuss supply and get
technical information from AlliedSignal about improving PFI’s Superline products. Foote dep.
at 84-86, 92-93 (Dkt. No. 211-30 at 28-33); Kavesh Ex. 19 (Dkt. No. 211-21). Foote wanted to
make PFI’s Superlines even stronger and thinner, and was focused on seeing if AlliedSignal
could supply stronger or thinner yarns. Id. These were common concerns for all fishing line
manufacturers; as Foote stated: “we weren’t the only ones who knew those were valuable
properties. . .” Foote dep. at 28-29 (Dkt. No. 211-30 at 5-6).
At the August 1994 meeting, AlliedSignal recommended that PFI heat stretch braided
fishing lines. Kavesh ¶ 39 (Dkt. No. 211-2 at 9). Foote indicates that he went to the meeting
with AlliedSignal not intending to say anything about heat drawing braided fishing lines.2 Foote
dep. at 103-105 (Dkt. No. 211-30 at 33-35). Foote testified that he was aware of the technique of
heat drawing, as that technique had been used on monofilaments and on braided Dacron fishing
lines since the 1950s. Foote dep. at 54-55 (Dkt. No. 211-30 at 10-11). Foote testified that he
asked AlliedSignal during the August, 1994 meeting whether AlliedSignal could provide a
stronger, better fiber. Foote dep. at 105 (Dkt. No. 211-30 at 35).
1 The parties and witnesses use the terms “heat stretching” and “heat drawing” interchangeably.
2
Foote also indicated that as of the time of the August 1994 meeting with AlliedSignal, PFI was
already working on developing its fusion product. Foote dep. at 84-86 (Dkt. No. 211-30 at 2830).
15
In response to Foote’s inquiry, AlliedSignal indicated that one could obtain the desired
result by heat stretching after braiding, and showed Foote an example of a braided fishing line
which it had already heat stretched (Foote believes it was probably Spiderwire). Foote dep. at
59-61, 103-106 (Dkt. No. 211-30 at 12-14, 33-36). AlliedSignal owns the Dunbar Patent,
already several years old by the time of the August 1994 meeting. AlliedSignal’s memorandum
following the meeting identified heat stretching the braid as a “low hanging fruit” action item,
Kavesh Ex. 20 p. HON 7 (Dkt. No. 211-22 at 4), something Foote confirmed was “obvious to
do.” Foote dep. at 103-105 (Dkt. No. 211-30 at 33-35).
After the meeting, Foote sent a sample of PFI’s braided GSP line known as Gorilla Braid
to AlliedSignal.
Under Dr. Sheldon Kavesh’s direction,3 AlliedSignal subsequently heat
stretched the Gorilla Braid for PFI at a draw ratio of 2.1 and a temperature of 155°C. Kavesh ¶
39 (Dkt. No. 211-2 at 9) and Exs. 21-22 (Dkt. Nos. 211-23 and 211-24); see also Foote dep. at
109-110, 116 (Dkt. No. 211-30 at 37-39) and Reynolds Ex. 26 (Dkt. No. 211-51). AlliedSignal’s
heat stretching substantially increased tenacity. Kavesh ¶ 39 (Dkt. No. 211-2 at 9) and Ex. 21
(Dkt. No. 211-23); Foote dep. at 119-121 (Dkt. No. 211-30 at 40-42) and Reynolds Ex. 26 (Dkt.
No. 211-51). Foote recorded in his notebook that AlliedSignal’s heat stretching resulted in the
highest tenacities he had ever tested in a braided fishing line. Foote dep. at 119-121 (Dkt. No.
211-30 at 40-42) and Reynolds Ex. 26 (Dkt. No. 211-51); Cook dep. at 89-90 (Dkt. No. 211-29
at 27-28).
AlliedSignal and PFI did not collaborate further.
Dan Foote explained that
collaboration stopped because AlliedSignal was supplying Spiderwire, at the time PFI’s main
competitor in the Superline market. Foote dep. at 11-12, 131 (Dkt. No. 211-30 at 3-4, 43).
3
Dr. Kavesh was named as an expert for Normark in this action and was deposed in that
capacity. Because of his prior employment with AlliedSignal, his testimony also touches on
some factual matters.
16
PFI turned to DSM, the supplier of Dyneema material. Foote testified that he visited
DSM twice in 1994, and that he made notes in his notebook on October 4, 1994, immediately
after returning from one visit to DSM. Foote dep. at 40, 48-49 (Dkt. No. 211-30 at 7-9);
Reynolds Ex. 26 (Dkt. No. 211-51). Foote also testified that he was aware of the benefits of heat
drawing a braided fishing line before his visit to DSM, as this technique had been used since the
1950s, and AlliedSignal had suggested heat drawing during his earlier visit in August 1994.
Foote dep. at 54-55 (Dkt. No. 211-30 at 10-11). According to Foote, because he was already
aware of the concept of heat drawing, his intention was to obtain DSM’s recommendations for
post-braid treating. Foote dep. at 77-78 (Dkt. No. 211-30 at 24-25).
DSM, like AlliedSignal, recommended heat stretching of braided fishing lines, and made
specific suggestions concerning the heat stretching parameters. Foote dep. at 54-55, 64-66 (Dkt.
No. 211-30 at 10-11, 16-17). Foote’s notebook describes DSM’s recommendations in detail:
DSM Trip....
new product ~ ideas included:....
(B) Heat Setting.
they [DSM] recommend heat drawing finished braids. the temperature is 130+2ºC....
they recommend drawing of
A) up to 35% (length) (wt)
B) up to 15% of Breakload
their draw is to optimize braiding construction + extra draw of fiber (reducing denier)
they ran tests on Gorilla braid before & after post draw at the 35% stretch. Tensile
kN/g/m went from 2.25 to 3.07. denier reduced 35%.
Reynolds Ex. 26 (Dkt. No. 211-51); Foote dep. at 55, 64-68 (Dkt. No. 211-30 at 10-11, 15-19).
As Foote’s notebook records, DSM heat stretched some of the Gorilla Braid using its
recommended parameters. Reynolds Ex. 26 (Dkt. No. 211-51); Foote dep. at 73-78 (Dkt. No.
211-30 at 20-25). DSM’s heat stretching increased tenacity. Id. Foote communicated DSM’s
recommendations to Cook after he returned to Iowa. Cook dep. at 102, 108-109 (Dkt. No. 21129 at 31, 36-37); Foote dep. at 81-82 (Dkt. No. 211-30 at 26-27).
17
Roger Cook testified that Foote’s notebook indicates that “it was DSM that was
recommending to Dan Foote heat drawing of finished braids.” Cook dep. at 104 (Dkt. No. 21129 at 32). When questioned concerning Foote’s notebook, Cook confirmed that the specific
parameters he used in his October 5, 1994 initial heat stretching work, including the temperature
and draw ratio parameters, were based on information Foote obtained from DSM. Cook dep. at
102, 104-106 (Dkt. No. 211-29 at 30, 32-34). He also testified that “DSM’s technical people
taught Mr. Foote how to do heat stretching to increase tenacity and reduce denier.” Cook dep. at
106 (Dkt. No. 211-29 at 34).
Cook’s October 5, 1994 notebook entry confirms that he followed DSM’s
recommendations exactly, using a temperature of 130°C and a draw ratio of 1.35 for his first
post-braid drawing. Reynolds Ex. 25 (Dkt. No. 211-50); Cook dep. at 104-109 (Dkt. No. 211-29
at 32-37). Foote also confirmed that Cook’s notebook entry regarding his October 5, 1994 work
indicated that Cook used the temperature and draw ratio suggested by DSM. Foote dep. at 81
(Dkt. No. 211-30 at 26).
Cook testified that he used these heat stretching parameters because DSM recommended
them:
Q. And just to put us back in context 1181
page 1181 is your
October 5, 1994 lab notebook entry showing the first time that
Berkley did heat stretching of the braid; correct? Just to put us
back in context.
A. Yes.
Q. And this is the document that was identified as
this is the
conception date of the ‘214 patent, October 5, ‘94; right?
A. Right.
Q. And so it’s the day after Mr. Foote’s notebook entry which I
understand comes after he’s back from the DSM trip; correct?
18
A. Yes.
Q. And Mr. Foote says that DSM recommends drawing at 130
degrees; correct?
A. Correct.
Q. And that’s what you did on October 5th. Your first entry
indicates drawing at 130 degrees; correct?
A. Correct.
Q. And you did that because that’s what DSM recommended;
right?
A. I must assume that’s correct.
Q. And DSM also recommended drawing it at 35 percent. And
that’s what you did; right? On October 5th you drew it 1.35?
A. Yes.
Q.
And again, you did that because that’s what DSM
recommended to Mr. Foote to do; correct?
A. That’s what Dan Foote recommended as a starting point.
Cook dep. at 108-109 (Dkt. No. 211-29 at 36-37).
Cook conceded that DSM’s recommendations match the claims of the ‘214 patent, noting
there was “no difference” between claim 1 and what DSM told Foote to do. Cook dep. at 113
(Dkt. No. 211-29 at 38). DSM’s recommended 1.35 draw ratio is within the scope of claims 4
and 5 as well.
Cook testified repeatedly that he did not conceive of the idea of using heat stretching to
increase the tenacity of braided fishing line, the invention claimed in the ‘214 patent. Cook dep.
at 37-45 (Dkt. No. 211-29 at 15-23). Initially, Cook testified that “it was DSM’s idea to use heat
stretching to improve the tenacity,” Cook dep. at 37 (Dkt. No. 211-29 at 15), and he also stated
that the idea to heat stretch braided line came through Foote from DSM, or AlliedSignal, or both.
Cook dep. at 37-38, 42 (Dkt. No. 211-29 at 15-16, 20).
19
After a break in the deposition, Cook changed his testimony somewhat, by noting that he
did not know whether Foote, DSM, or AlliedSignal conceived of using heat stretching to
improve the tenacity of a fishing line; but he confirmed that it was not his idea:
Q. And what you’re saying now is you don’t know who suggested
drawing the fishing line to increase tenacity, whether it was Allied
Signal or Dan Foote or DSM or Dan Foote. You just don’t know?
A. No.
Q. Is that correct?
A. Right
***
Q. What you do recall is both DSM and AlliedSignal heat
stretched fishing line for Dan Foote?
A. Yes.
Q. And what you originally told me was that AlliedSignal
suggested heat stretching to increase the tenacity of the fishing
line; correct?
A. Yes.
Q. And what you originally told me was DSM suggested heat
stretching the fishing line to increase the tenacity; correct?
A. Yes.
Q. And now you’re changing your testimony to say that you don’t
know who suggested heat stretching the fishing line to increase
tenacity; correct?
A. Correct.
Q. And both of these events occurred before October 5, 1994,
your conception date; correct?
A. Yes.
***
20
Q. ... I understand your testimony now to be either Dan Foote or
AlliedSignal suggested heat stretching to increase tenacity and you
don’t know which one?
A. Right.
Q. But it wasn’t you?
A. Right.
Q. And same with DSM. Either Dan Foote or DSM suggested the
heat stretching process to increase tenacity, but it wasn’t you?
A. Right.
Cook dep. at 43-45 (Dkt. No. 211-29 at 21-23).
When Cook was asked what he believed he had invented, he did not claim credit for
inventing the subject matter of claims 1, 4 and 5. Instead, Cook testified that what was new
about his work was that “we pushed the draw ratios to a high level.” Cook dep. at 38-39 (Dkt.
No. 211-29 at 16-17). As noted above, the ‘214 patent claims a draw ratio starting at the lowest
possible level, “about 1.0,” and the asserted claims encompass DSM’s recommended draw ratio.
Cook also said, “What we came up with was a process for making a braided fishing line high
tenacity,” but admitted “that’s what DSM and AlliedSignal both told [him] to do.” Cook dep. at
38-39 (Dkt. No. 211-29 at 16-17). Cook also suggested that his use of a higher temperature
(150°C rather than DSM’s suggested 130°C) distinguished his work from DSM’s, but then
conceded that DSM’s recommended temperature was within the scope of the ‘214 patent claims.
Cook dep. at 113 (Dkt. No. 211-29 at 38).
PFI proffers several arguments in support of its position that Cook is the true inventor.
First, PFI relies on Cook’s sworn declaration filed with the ‘214 patent application, claiming
inventorship. Second, PFI relies on evidence that Cook was experimenting with “heat treating”
braided GSP fishing line in 1993, before DSM’s recommendations. PFI relies on pages from
21
Cook’s notebook, PFI 112-14, which describe a May, 1993 “heat set” experiment, and page PFI
6207 from Dan Foote’s notebook, which refers to Cook’s work “heat treating” gel-spun
polyethelene braids. Dkt. Nos. 237-7, 237-8, relying on documents PF 1112-14 and PF 6207. In
response, Normark notes that “heat treating” is not “heat stretching.” Normark explains, relying
on Cook’s testimony and the testimony of its expert Dr. Kavesh, that the “heat treating” referred
to in these documents is a heat treatment to stabilize the material that is typically performed
without stretching, and that the PFI documents do not refer to stretching, draw ratio, or any
increase in tenacity. Cook dep. at 35-36, 45-47 (Dkt. No. 241-8 at 4-8); PF 1112-14 (Dkt. No.
244-7), PF_3_6207 (Dkt. No. 244-8); Second Kavesh Dec. (Dkt. No. 241-1).
Third, PFI relies on testimony from Dan Foote, indicating his and PFI’s general
awareness of heat stretching before the AlliedSignal and DSM meetings, and Foote’s belief that
Cook was working on something new involving heat stretching of braided line. Foote dep. at 6869, 84-88 (Dkt. No. 244-4 at 9-10, 12-16). Normark responds by noting that Foote disclaimed
personal knowledge of Cook’s work and stated that he was “not involved” in Cook’s ‘214 patent
work. Foote dep. at 31-32, 81, 204-205 (Dkt. No. 260-7 at 3-4, 6-8). Normark also argues that
Foote’s testimony does not contradict Cook’s specific testimony and does not show that Cook
had possession of all elements of claims 1, 4, and 5 before receiving DSM’s recommendations.
Dkt. No. 260 at 10 (p. 5).
Finally, PFI relies on testimony from its expert, Egbert van Gorp, who was DSM’s
Research Technology and Development Manager in 1994. Mr. van Gorp testified that DSM did
not have “independently developed know how and technology” concerning the use of heat
stretching with fishing lines, and also that he was not aware of DSM stretching braided fishing
lines before October 5, 1994. van Gorp dep. at 239 (Dkt. No. 244-11 at 6). Normark responds
22
by noting that van Gorp was not able to testify about DSM’s recommendations as recorded in
Foote’s notebook, because he had no memory of that issue. van Gorp dep. at 211-16 (Dkt. No.
260-8 at 9-14). Normark also argues that van Gorp’s testimony is irrelevant, and that he cannot
deny that DSM recommended the use of heat stretching as recorded in Dan Foote’s notebook.
Dkt. No. 260 at 10 (p. 5).
VII.
PFI’S 1995 FIRELINE FUSED PRODUCT
PFI does not dispute that its 1995 Fireline Fused products were on sale more than one
year before PFI filed the ‘214 patent application.
Reynolds Ex. 20 (Dkt. No. 211-45).
Comparing the 1995 Fireline Fused manufacturing process to the specific elements of the ‘214
patent claims, PFI admits that its 1995 Fireline Fused product:
·
was a braided fishing line;
·
was made up of 3-64 GSP yarns;
·
that each of the yarns was in the range of 20-1000 denier;
·
that the line was stretched at a total draw ratio of between 1.0 and
2.0; and
·
that the stretching increased the line’s tenacity.
Reynolds Ex. 19 (Dkt. No. 211-44).
PFI further admits that some of its 1995 Fireline Fused product was made by a process
that included a first drawing stage at 150ºC and a second drawing stage at 153ºC. Id. at 5-6
(Dkt. No. 211-44 at 6-7). Roger Cook was responsible for setting up the 1995 Fireline Fused
manufacturing process. Cook dep. at 22-23 (Dkt. No. 211-29 at 5-6). His notebook and PFI’s
1995 Fireline Fused process document indicate PFI used a two stage drawing process for the
1995 Fireline Fused products, with a first stage set at 150°C or 151°C, and a second stage set at
153°C or 154°C. Reynolds Exs. 19, 22, 23, 24 (Dkt. Nos. 211-44, 211-47, 211-48 and 211-49);
23
see also van Gorp dep. at 153-57 (Dkt. No. 211-33 at 58-62); Reynolds Ex. 24 (Dkt. No. 21149); Cook dep. at 23-25, 29-31 (Dkt. No. 211-29 at 6-11). The first stage used a draw ratio of
1.4, and the second stage a draw ratio of 1.36, for a total draw ratio of 1.9. Reynolds Ex. 22
(Dkt. No. 211-47); van Gorp dep. at 153-57 (Dkt. No. 211-33 at 58-62); and Reynolds Ex. 24
(Dkt. No. 211-49). PFI’s expert concedes that stage 1 of the 1995 Fireline Fused process
matches claims 1, 4, and 5 of the ‘214 patent. van Gorp dep. at 167-68 (Dkt. No. 211-33 at 6768).
PFI makes two arguments in opposition to Normark’s on-sale bar defense. First, PFI
argues that the 1995 Fireline Fused products were “fused” products, and that the ‘214 patent
claims are limited to “unfused” fishing lines. Second, PFI argues that the second stage of the
1995 Fireline Fused manufacturing process, at 153°C, is sufficient to differentiate it from the
‘214 patent claims, which claim heat stretching at “about 150°C.” Because both of these
arguments are legal in nature, they are addressed in the legal discussion section of this order.
See infra Discussion § III.
VIII. FACTS RELEVANT TO PFI’S MOTION FOR SUMMARY JUDGMENT ON
NORMARK’S INEQUITABLE CONDUCT COUNTERCLAIM
Normark contends that the ‘214 patent is unenforceable for inequitable conduct because
Roger Cook falsely claimed to be the true inventor of the ‘214 patent claims, and PFI did not
disclose DSM’s role to the Patent Office; because Cook and PFI’s patent lawyer, Lance Johnson,
did not disclose the 1995 Fireline Fused product to the Patent Office during prosecution; because
PFI made what Normark argues are false statements of fact concerning the Hogenboom patent;
and because PFI did not disclose the Gibbs article describing braided GSP fishing lines and the
Shimizu reference. PFI moved for summary judgment, arguing that Normark had insufficient
evidence of materiality and intent.
24
The facts concerning inventorship and the 1995 Fireline Fused are discussed above.
Regarding PFI’s remarks to the examiner concerning Hogenboom, Normark argues, inter alia,
that PFI improperly argued to the examiner that no prior art bridged the gap between the ropemaking process of Hogenboom and the process for fishing line addressed in the application
which became the ‘214 patent. The court will not detail all of Normark’s contentions regarding
the Hogenboom patent issue, which can be found at pages 9-14 of Normark’s brief in response to
PFI’s motion for summary judgment on Normark’s inequitable conduct counterclaim, Dkt. 241
at 13-18.
DISCUSSION
I.
SUMMARY JUDGMENT STANDARD
Summary judgment should be granted if “the movant shows that there is no genuine
dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed.
R. Civ. P. 56(a). It is well established that summary judgment should be granted “only when it
is clear that there is no dispute concerning either the facts of the controversy or the inferences to
be drawn from those facts.” Pulliam Inv. Co. v. Cameo Properties, 810 F.2d 1282, 1286 (4th
Cir. 1987).
The party moving for summary judgment has the burden of showing the absence of a
genuine issue of material fact, and the court must view the evidence before it and the inferences
to be drawn therefrom in the light most favorable to the nonmoving party. United States v.
Diebold, Inc., 369 U.S. 654, 655 (1962).
Rule 56(c)(1) provides as follows:
(1) A party asserting that a fact cannot be or is genuinely disputed must
support the assertion by:
(A) citing to particular parts of materials in the record, including
depositions, documents, electronically stored information,
25
affidavits or declarations, stipulations . . . , admissions,
interrogatory answers or other materials; or
(B) showing that the materials cited do not establish the absence or
presence of a genuine dispute, or that an adverse party cannot
produce admissible evidence to support the fact.
Fed. R. Civ. P. 56(c)(1).
A party “cannot create a genuine issue of material fact through mere speculation or the
building of one inference upon another.” Beale v. Hardy, 769 F.2d 213, 214 (4th Cir. 1985).
Therefore, “[m]ere unsupported speculation . . . is not enough to defeat a summary judgment
motion.” Ennis v. National Ass’n of Bus. & Educ. Radio, Inc., 53 F.3d 55, 62 (4th Cir. 1995).
In considering whether a reasonable finder of fact could find for the non-moving party,
the court must also consider the applicable burden of proof, and which party bears that burden of
proof. Anderson v. Liberty Lobby, Inc., 477 U.S. 242 (1986). For example, with respect to
Normark’s motion seeking a summary judgment of invalidity, Normark has the burden of
proving invalidity by clear and convincing evidence.
II.
NORMARK’S MOTION FOR SUMMARY JUDGMENT THAT THE ‘214
PATENT IS INVALID UNDER SECTION 102(f)
A patent is invalid if the inventor “did not himself invent the subject matter sought to be
patented.” 35 U.S.C. § 102(f). To prove invalidity under Section 102(f), Normark must prove
two elements: (1) prior conception of the invention by another; and (2) communication of the
prior conception to the patentee. Creative Compounds, LLC v. Starmark Labs., 651 F.3d 1303,
1313 (Fed. Cir. 2011); Eaton Corp. v. Rockwell Int’l Corp., 323 F.3d 1332, 1344 (Fed. Cir.
2003). Derivation is a question of fact. Brand v. Miller, 487 F.3d 862, 870 (Fed. Cir. 2007).
Normark has the burden of proving invalidity under Section 102(f) by clear and convincing
evidence. Price v. Symsek, 988 F.2d 1187, 1194 (Fed. Cir. 1193).
26
The court finds that there is no genuine issue of material fact, and that Normark has
proven that claims 1, 4, and 5 of the ‘214 patent are invalid under Section 102(f) by clear and
convincing evidence. The evidence detailed above in Part VI establishes that: 1) Cook testified
to a conception date of October 5, 1994, and that conception date is corroborated by Cook’s
October 5, 1994 notebook entry;4 2) Before October 5, 1994, DSM conceived of the same
invention, recommending to Dan Foote of PFI that PFI should heat stretch braided fishing line
using parameters that match Claims 1, 4, and 5; 3) Before October 5, 1994, DSM also heat
stretched Gorilla Braid for PFI, following the parameters of Claims 1, 4, and 5; 4) DSM’s prior
conception was communicated to Cook by Dan Foote before October 5, 1994; and 5) Cook
admitted that it was not his idea to use heat stretching to increase tenacity, and that he based his
October 5, 1994 “conception” on DSM’s recommendations.
Normark has thus proven the two necessary elements of derivation by clear and
convincing evidence: (1) DSM conceived of the claimed invention before Cook’s claimed
conception date; and (2) DSM’s prior conception was communicated to Cook.
Creative
Compounds, LLC v. Starmark Labs., 651 F.3d 1303, 1313 (Fed. Cir. 2011).
PFI does not dispute the details of Normark’s derivation evidence. Instead, PFI contends
that there is a genuine issue of material fact as to whether Roger Cook conceived of the
inventions claimed in the ‘214 patent before DSM, and not on October 5, 1994. This court must,
therefore, determine whether PFI has submitted sufficient evidence from which a jury could
reasonably find that Cook conceived of the inventions claimed in Claims 1, 4, and 5 not on
4
In its interrogatory response, PFI described the conception date as “at least as early as October
5, 1994,” suggesting the possibility of an earlier conception date. PFI has not presented
evidence that a reasonable jury could find supports an earlier conception date.
27
October 5, 1994, but at some earlier date before DSM’s recommendations were made to Dan
Foote. Hawkins v. PepsiCo, Inc., 203 F.3d 274, 279 (4th Cir. 2000), cert. denied 531 U.S. 875.
The standard for conception has been settled for over 100 years. Conception occurs
when the inventor has “a definite and permanent idea of the complete and operative invention, as
it is thereafter to be applied in practice. Mergenthaler v. Scudder, 11 App. D.C. 264, 1897 WL
17698, *6 (D.C. Cir. 1897); see Coleman v. Dines, 754 F.2d 353, 359 (Fed. Cir. 1985).
Furthermore, conception evidence must be corroborated. Singh v. Brake, 222 F.3d 1362, 1367
(Fed. Cir. 2000). Accordingly, in order to avoid summary judgment on the issue of inventorship,
PFI must show that a genuine issue of material fact exists with respect to the question of whether
Roger Cook conceived of the invention recited in the asserted claims (that is, that he had a
“definite and permanent idea” of all elements of Claims 1, 4, and 5) prior to Dan Foote’s
communication of DSM’s recommendation to Mr. Cook.
The court has reviewed PFI’s proffered evidence to see whether it raises a genuine issue
of material fact from which a jury could find for PFI on this issue, and finds that it does not. As
an initial matter, that Cook signed a declaration asserting he was the sole inventor when he
applied for the patent does not contradict the evidence of derivation, because such a statement is
required to apply for a patent. Any other rule would mean a claim could never be invalidated for
lack of inventorship on summary judgment, no matter how clearly the inventor disavows
inventorship.
PFI’s reliance on evidence that Cook was experimenting with heat treating fishing line as
far back as 1993 also does not raise a genuine issue of material fact. The cited evidence, namely
Cook’s notebook pages and Foote’s deposition testimony, is either not specific to the invention
claimed in the ‘214 patent, which relates to heat stretching braided GSP line; or that evidence
28
fails to suggest that Cook had a definite and permanent idea of the complete and operative
invention claimed in the ‘214 patent claims before October 5, 1994. PFI’s documents and
Foote’s testimony about Cook’s prior work do not support an inference that Roger Cook had a
“definite and permanent idea” of all elements of claims 1, 4, and 5 before October 5, 1994.
Singh, 222 F.3d at 1367. The PFI documents do not show “stretching” at a “total draw ratio
within the range from about 1.0 to about 2.0”, as required by claim 1, or within the narrower
ranges as required by claims 4 and 5. Indeed, the PFI documents do not contain any reference to
heat stretching, and also do not contain any reference to an increase in tenacity. Cook’s prior
work related to “heat relaxing” (or “heat setting”) which is a form of heat treating distinct from
the heat stretching described and claimed in the ‘214 patent.
PFI relies primarily on Dan Foote’s testimony to suggest that Cook was mistaken in his
recollection of events. Foote’s testimony regarding his meetings with AlliedSignal and DSM is,
however, entirely consistent with Cook’s testimony. At most, Foote’s testimony suggests that,
prior to visiting AlliedSignal and DSM, Foote believed Cook or others at Pure Fishing had a
general idea which might be somehow unique or not yet in practice regarding how to improve
braided fishing line using heat stretching techniques.
Foote’s visits to AlliedSignal and DSM confirmed, however, that both entities had the
same idea, and that at least AlliedSignal had already heat stretched braided line to achieve the
desired improvement in tenacity. Foote also conceded that AlliedSignal described this method of
improving tenacity as “low hanging fruit,” and that this reference was consistent with calling it
obvious. His testimony as a whole fully supports the conclusion that heat stretching braided line
was well known and applying those techniques to braided GSP yarn was obvious. It also
supports the conclusion that Cook’s progression from the general idea of heat stretching to a
29
definite and permanent idea of the complete and operative invention claimed in the ‘214 patent
began with application of suggestions received from DSM.
Foote’s apparent belief that Cook was working on developing something new involving
heat stretching of braided line even before Foote’s meetings with AlliedSignal and DSM does
not raise a genuine issue of material fact. Foote’s testimony is nothing more than a statement of
belief regarding what Cook may have been working on. The court finds that Foote’s testimony
is not sufficient to contradict Cook’s own testimony regarding the scope of his work.
In any event, PFI has presented no evidence that Cook had reduced his invention to
sufficiently concrete form prior to October 1994 to claim conception on his own prior to
receiving specific suggestions from DSM, which Cook conceded predated his first experiment
with heat stretching braided GSP lines. At most, Cook suggests that his later experiment may
have supported invention of a much narrower concept than is claimed in the ‘214 patent. Cook’s
attempt to explain how his work on and after October 5, 1994, differed from what DSM
suggested also does not raise a genuine issue of material fact. Cook’s testimony addresses only
one small portion of his claimed invention, heating and stretching at the upper end of the heat
and draw-ratio spectrum, and does not address the much broader scope of the claims at issue
here.
Finally, PFI’s references to van Gorp’s testimony are out of context and too limited to
create a genuine issue of material fact on the issue of derivation. For example, that DSM may
not have independently developed know-how and technology with respect to drawing braided
fishing line, as van Gorp claims, does not mean that DSM did not conceive of the idea to draw
such line based on information gained from other sources. Certainly van Gorp’s assertion does
not contradict the testimony from Cook and Foote that DSM provided the specific
30
recommendation and parameters that Cook used in his first experiment. The same is true for van
Gorp’s testimony that he was not aware of DSM undertaking any stretching of braided fishing
line, which he explained was because DSM did not have the appropriate denier or braiding
equipment available.
The court finds that Normark is entitled to summary judgment that claims 1, 4, and 5 of
the ‘214 patent are invalid under Section 102(f), because there is clear and convincing evidence
that Roger Cook is not the true inventor.
III.
NORMARK’S MOTION FOR SUMMARY JUDGMENT THAT PFI’S 1995
FIRELINE FUSED INVALIDATES THE ‘214 PATENT CLAIMS UNDER
SECTION 102(b)
A patent is invalid if “the invention was... in public use or on sale in this country, more
than one year prior to the date of the application for patent in the United States.” 35 U.S.C.
§ 102(b). Proof of anticipation under § 102(b) requires clear and convincing evidence that a
single prior art reference contains each element of the claimed invention. Eli Lilly & Co. v. Barr
Labs., Inc., 251 F.3d 955, 962 (Fed. Cir. 2001).
As outlined above, PFI does not dispute that its 1995 Fireline Fused product was on sale
more one year before the ‘214 patent application. It has long been the law that the premature
public use or sale of a product bars the patentability of the manufacturing process, even if the
process is kept secret. Metallizing Eng’g. Co. v. Kenyon Bearing and Auto Parts Co., 153 F.2d
516, 519 (2d Cir. 1946) (Learned Hand, J.). Learned Hand’s rule remains the law (at least as to
patents issued before the Leahy-Smith America Invents Act).
D.L. Auld Co. v. Chroma
Graphics Corp., 714 F.2d 1144, 1147-48 (Fed. Cir. 1983); New Railhead Mfg., L.L.C. v.
Vermeer Mfg. Co., 298 F.3d 1290, 1297 (Fed. Cir. 2002).
The question, then, is whether the 1995 Fireline Fused manufacturing process anticipates
the ‘214 patent claims, or whether those claims are patentably distinct from the 1995 Fireline
31
Fused process. The court finds that Normark has demonstrated clear and convincing evidence
that PFI’s 1995 Fireline Fused process meets all elements of claims 1, 4, and 5 of the ‘214
patent. The claims are therefore invalid under Section 102(b).
PFI makes two arguments in its attempt to distinguish the ‘214 patent claims from the
1995 Fireline Fused manufacturing process.
First, PFI notes that the 1995 Fireline Fused
product was a “fused” product, meaning that the fishing line yarns or filaments were melted
together. PFI argues that the ‘214 patent claims should be limited to a process that results in an
“unfused” product. Second, PFI argues that the ‘214 patent claims are patentably distinct from
the 1995 Fireline Fused manufacturing process because the patent claims require heat stretching
at “about 150°C,” while the 1995 Fireline Fused process had a second stage of heat drawing at
153°C. The court rejects both arguments.
The court disagrees that the ‘214 patent claims should be construed to be limited to an
“unfused” product.
The first problem with PFI’s argument is that it did not seek such a
construction of the ‘214 patent during the claim construction phase of this litigation. Instead,
PFI sought to construe “about 150°C” to include heat stretching temperatures of up to 159°C.
Dkt. Nos. 74, 79. Such a broad construction would have gone well beyond the top temperature
used in making the 1995 Fireline Fused, an admittedly fused product.
PFI owns two patents related to the Fireline Fused products and process, U.S. Patent Nos.
5,540,990 and 6,148,597. Reynolds Exs. 2-3 (Dkt. Nos. 211-27 and 211-28). The ‘597 patent,
which issued after the filing of the ‘214 patent application, covers the process used to make 1995
Fireline Fused. The ‘597 patent’s claim 8 claims a heat stretching process within a range, the
low end of which is “about 150°C.” The ‘214 patent claims clearly overlap with the ‘597
patent’s temperature range, as the high end of the ‘214 patent’s temperature range is also “about
32
150°C.” Even if use of the term “about” allows only a two degree variation, this would mean the
temperature ranges in the two patents overlap by as much as five degrees. While PFI’s ‘597
patent is not directly implicated by the on-sale bar defense, it is significant because the ‘597
patent clearly claims a fused product. The overlap in the temperature ranges, therefore, requires
the conclusion that heat stretching at the temperature range claimed in the ‘214 patent claims
could result in a fused product, absent a clear limitation to an unfused product.
PFI argues that the court may find that the ‘214 patent claims are limited to “unfused”
products based on two comments found in the ‘214 patent specification. Specifically, PFI relies
on a comment following a group of 14 examples that the resulting product was unfused. ‘214
Patent, Reynolds Ex. 1, col. 9, l. 31-34 (Dkt. No. 211-26). PFI also relies on a reference to the
color of the resulting line at the conclusion of the process: the ‘214 patent states that “[l]ine
according to the invention retains the opaque white color characteristic of the virgin yarns.” Id.,
col. 3, l. 24-25. Neither of these references, however, is found in any claim limitation. There is,
likewise, no term in any relevant claim which might be construed using these references. It is,
therefore, doubtful that these references should be considered at all for purposes of determining
the scope of the claims at issue. See Phillips v AWH Corp., 415 F.3d 1303, 1320 (Fed. Cir.
2005) (en banc), cert. denied, 546 U.S. 1170 (2006).
Even if the court were to consider these two references, it would find that they do not
support importation of a limitation to an unfused product, for the following reasons. The
referenced examples, 28 through 41, are only 14 of the 79 examples given in the patent
specification. The other 65 examples do not state that they are unfused. The disclosure that
some examples are unfused is therefore entirely ambiguous. It could as easily be meant to
distinguish these unfused examples from other examples which resulted in fusing as to mean that
33
all examples are unfused. Thus, it does not support imposing a limitation not otherwise found in
the claims.
The reference to concluding coloration is also ambiguous. It could mean that the product
remains unfused, or it could mean it remains only minimally fused, leaving primarily the virgin
opaque white coloring. The context of the statement is significant here, as it is in a paragraph
noting how the color may be changed if some other coloration is desired. As with the reference
to absence of fusing in the group of fourteen examples, the possible interpretations are too
ambiguous to support an inference that the ‘214 patent was intended to be limited to unfused
products.
It is also of some significance that the Cook ‘990 and Cook ‘597 patents expressly and
repeatedly note that the process resulted in fused lines. This limitation is reflected in the claims
themselves. The ‘214 patent, by contrast, includes no express reference in the claims either to
fusion or lack of fusion. At most there are two references in the specification that might suggest
the resulting product should not be fused, and the court finds those insufficient for reasons
already discussed. This distinction between the ‘214 patent and the other Cook patents is
particularly significant as all three patents have the same inventor and were prosecuted by the
same attorney, Lance Johnson. Johnson dep. at 78 (Dkt. No. 241-6 at 13).
It is possible that Cook intended his ‘214 patent to be limited to unfused lines. He did
not, however, expressly limit it to unfused lines, and the other evidence PFI cites does not
compel importation of such a limitation into the claims.
With respect to PFI’s second argument, PFI has admitted that the 1995 Fireline Fused
product was a four yarn braid made from Spectra, with each yarn either 100 denier or 200 denier.
PFI has further admitted that the 1995 Fireline Fused was heat stretched in a two-stage drawing
34
process. It is undisputed that the first stage for some of the products used a draw ratio of 1.4 and
a temperature of 150°C, and the second stage used a draw ratio of 1.36 and a temperature of
153°C. The total draw ratio of the entire process was 1.9.
Therefore, there is no issue of material fact that stage one of the 1995 Fireline Fused
process performs each element of ‘214 patent claims 1, 4, and 5. PFI contends that the ‘214
patent is saved from invalidity, however, because the second stage used a temperature of 153°C.
That is the sole difference PFI has identified between the 1995 Fireline Fused process and the
‘214 patent claims, as properly construed. According to PFI, the claim limitation of “about
150°C,” which the court has construed to mean “approximately 150°C,” is patentably distinct
from the use of 153°C in the 1995 Fireline Fused process.
The court finds that PFI is wrong as a matter of law. The second stage of the 1995
Fireline Fused process cannot save the validity of the ‘214 patent claims. The question of
anticipation simply asks whether a single prior art reference contains all the elements in a patent
claim. Hakim v. Cannon Avent Grp., PLC, 479 F.3d 1313, 1319 (Fed. Cir. 2007). If so, the fact
that the reference has an additional step or additional features does not change the result. See
e.g., Powdermagic, Ltd. v. Rossignol Ski Co., Inc., No. 1:04-CV-001332005, WL 3981617, at *6
(D. Utah Aug. 4, 2005) (“the fact that a prior art reference teaches additional or alternate features
will not diminish the reference’s satisfaction of the limitations”); Mossman v. Broderbund
Software, Inc., No. 98 71244 DT, 1999 WL 696007, at *8 (E.D. Mich. May 18, 1999) (“if all
the elements discussed are included in the prior art reference, the claim is anticipated even if
additional elements are used in the reference.”); Everything Baseball v. Wilson Sporting Goods
Co., 611 F. Supp. 2d 832, 835 (N.D. Ill. 2009) (“provided all limitations of the patent-in-suit are
present in a prior art reference, the presence of ‘additional’ features in the prior art reference
35
does not undermine its satisfaction of the criteria for anticipation”). The leading treatise on
patent law makes this point as follows: “for anticipation purposes, as for infringement purposes,
it does not matter that the anticipatory (or infringing) item contains elements in addition to those
specified in the patent claim in question.” Chisum on Patents, § 3.02[1][f].
The court, therefore, finds that Normark is entitled to summary judgment that claims 1, 4,
and 5 of the ‘214 patent are invalid under Section 102(b). The evidence is clear and convincing
that the 1995 Fireline Fused product was on sale more than one year before PFI applied for the
‘214 patent, and that the manufacturing process for the 1995 Fireline Fused meets all elements of
claims 1, 4, and 5.
IV.
NORMARK’S MOTION FOR SUMMARY JUDGMENT OF ANTICIPATION,
BASED ON DUNBAR, AND ITS MOTION FOR SUMMARY JUDGMENT OF
OBVIOUSNESS
Normark also seeks summary judgment on an additional ground under Section 102(b),
arguing that the Dunbar patent’s Example 7 anticipates Claims 1, 4, and 5 of the ‘214 patent. In
the alternative, Normark seeks summary judgment that the patent claims are invalid as obvious,
relying on Dunbar as the primary reference.
The court denies Normark’s motion for summary judgment of anticipation based on
Dunbar Example 7. The differences in the denier of the yarns used in Dunbar Example 7 create
at least a genuine issue of material fact concerning whether the ‘214 patent was anticipated by
Dunbar Example 7.
The court is not, however, persuaded by PFI’s other attempted distinctions between
Dunbar Example 7 and the ‘214 claims. Specifically, for the reasons explained below, the court
concludes that the ‘214 patent claims are not limited to “fully-drawn yarns” of 30 grams per
denier or more, as PFI and its expert contend.
36
The first difficulty with PFI’s argument is that the “fully drawn yarns” limitation is not
expressly stated in any claim of the ‘214 patent, and PFI did not ask the court to construe the
claims to include such a limitation during the claim construction phase of this case. In any
event, PFI’s argument is defeated by the language of the patent itself. The detailed description
of the invention contained in the ‘214 patent specification states that the process should be
practiced using yarns with a tenacity of at least 15 grams per denier. ‘214 Patent, col. 2, l. 39
(Dkt. No. 211-26). According to van Gorp, a “fully-drawn yarn” at the time of the ‘214 patent
application was one which had a tenacity of 30 grams per denier or more. Van Gorp report,
Reynolds Ex. 11, p. 5 (Dkt. No. 211-36 at 6); van Gorp dep. at 79 (Dkt. No. 211-33 at 27). Thus,
PFI’s own expert defined fully drawn lines as having a minimum tenacity (grams per denier
(“gpd”)) which was double the tenacity disclosed in the patent specification. Given the explicit
reference in the ‘214 patent specification to the use of yarns that are not fully drawn (15 gpd
versus 30 gpd), the evidence does not support a conclusion that the ‘214 patent is limited to the
use of fully-drawn yarns.
PFI’s next argument is that the ‘214 patent claims are limited to a “fishing line”, and that
the claims should be interpreted such that the 64 yarn by about 1000 denier construction set forth
in the claims is not included within the claim scope. The court rejects that argument, and finds
that the language of the claims clearly provides that braided structures up to 64 yarns by about
1000 deniers are within the scope of the ‘214 patent claims.
The court next considers Normark’s motion for summary judgment that the ‘214 patent
claims are invalid as obvious under 35 U.S.C. § 103. A patent is invalid “if the differences
between the subject matter sought to be patented and the prior art are such that the subject matter
as a whole would have been obvious at the time the invention was made to a person of ordinary
37
skill in the art...” 35 U.S.C. § 103. The ultimate question of obviousness is a legal issue. KSR
Int’l Co. v. Teleflex Inc., 550 U.S. 398, 427 (2007); Graham v. John Deere Co., 383 U.S. 1, 17
(1966). Obviousness requires consideration of three underlying factual issues: 1) the scope and
content of the prior art, 2) the differences between the prior art and the claimed invention, and 3)
the level of ordinary skill in the art. KSR, 550 U.S. at 406. Where those issues are not in
material dispute, summary judgment is appropriate.
Id. at 427.
If proffered, secondary
considerations such as a long-felt but unsolved need, commercial success, or contemporaneous
invention by others, should be considered. Id. at 406. To be relevant, secondary factors must be
linked to the patented features, and even then secondary factors cannot defeat summary
judgment if there is a strong showing of obviousness. Stamps.com Inc. v. Endicia, Inc., 437 Fed.
App’x 897, 905 (Fed. Cir. 2011); Sundance, Inc. v. Demonte Fabricating Ltd., 550 F.3d 1356,
1368 (Fed. Cir. 2009); Muniauction, Inc. v. Thomson Corp., 532 F.3d 1318, 1328 (Fed. Cir.
2008); see also Wyers v. Master Lock Co., 616 F.3d 1231, 1246 (Fed. Cir. 2010).
The Supreme Court teaches that “[t]he combination of familiar elements according to
known methods is likely to be obvious when it does no more than yield predictable results.”
KSR, 550 U.S. at 416. KSR also taught that “if a technique has been used to improve one device,
and a person of ordinary skill in the art would recognize that it would improve similar devices in
the same way, using the technique is obvious unless its actual application is beyond his or her
skill.” Id. at 417. The “person of ordinary skill” is presumed to have full knowledge of all of the
prior art. Therasense, Inc. v. Becton, Dickinson & Co., 565 F.Supp.2d 1088, 1103 (N.D. Cal.
2008), rev’d on other grounds, 649 F.3d 1276 (Fed. Cir. 2011); Rothman v. Target Corp., 556
F.3d 1310, 1318 (Fed. Cir. 2009). That omniscient “person of ordinary skill” also has common
38
sense, “and in many cases a person of ordinary skill will be able to fit the teachings of multiple
patents together like pieces of a puzzle.” KSR, 550 U.S. at 420.
The court finds claims 1, 4, and 5 invalid as obvious in light of the teachings of Dunbar
and Hogenboom, combined with 1995 Fireline Fused. There is no material dispute concerning
the factual issues underlying obviousness.5 The scope and content of Dunbar Example 7,
Hogenboom, and 1995 Fireline Fused are not disputed. It is also not disputed that the only
difference between Dunbar Example 7 and claims 1, 4, and 5 is that Dunbar Example 7 used
yarns with a denier of 1190, while the claims require yarns of “about 1,000” denier. The 1995
Fireline Fused disclosed the use of yarns of less than 1000 denier in a heat stretching process
that, as discussed above, matches the claims of the ‘214 patent. To the extent there was any gap
to be bridged between Dunbar and Hogenboom and the application of the technology and
concepts in those patents to the production of fishing line, the court finds that 1995 Fireline
Fused bridged that gap.6 The court finds as a matter of law that the inventions claimed in claims
1, 4, and 5 would have been obvious to a person of ordinary skill having knowledge of Dunbar,
Hogenboom, and the 1995 Fireline Fused. KSR, 550 U.S. at 416-17.
PFI argues that secondary considerations of a long-felt but unsolved need, alleged
copying, and the commercial success of products manufactured according to the ‘214 patent
5
Normark describes a small difference between the definitions of a person of ordinary skill in
the art employed by the experts for the two parties, Dkt. No. 211-1 at 35 (p. 29 n. 6), but
neither party argued that that difference created a material issue of fact in this context.
6
The court notes that Normark argued that additional references could be combined with Dunbar
Example 7 to satisfy the “about 1,000 denier” limitation, including Dunbar’s own disclosure
of smaller denier yarns, the commercially available smaller denier yarns, or the prior art
braided Superlines on the market as described in the Gibbs and In Fisherman articles. See
Dkt. No. 211-1 at 36-37 (pp. 30-31). The court finds it unnecessary to consider each possible
combination, in light of its ruling herein.
39
claims support a finding of nonobviousness. Dkt. No. 244 at 35-38 (pp. 30-33). Normark
disputes PFI’s secondary considerations evidence, and also argues that PFI failed to show a
nexus between the alleged secondary considerations and the ‘214 patent claims. Dkt. No. 260 at
23-25 (pp. 18-20). Normark also relies on the DSM and AlliedSignal work, arguing that that
prior, or at a minimum contemporaneous, independent invention is a secondary factor supporting
a finding of obviousness. Id., at 24 (p. 19).
Whatever the merit of PFI’s secondary considerations evidence, the court finds such
evidence is not sufficient to overcome the strong direct evidence of obviousness. Stamps.com
Inc. v. Endicia, Inc., 437 Fed. App’x 897, 905 (Fed. Cir. 2011); Sundance, Inc. v. Demonte
Fabricating Ltd., 550 F.3d 1356, 1368 (Fed. Cir. 2009). The court also agrees with Normark
that DSM and AlliedSignal’s independent recommendations to PFI to heat stretch braided
fishing lines, occurring prior to PFI’s alleged conception date, support a finding of obviousness.
The court therefore concludes that Normark is entitled to summary judgment on the issue of
obviousness.
V.
NORMARK’S MOTION FOR SUMMARY
ALLEGATION OF WILLFUL INFRINGEMENT
JUDGMENT
ON
PFI’S
To prove willful infringement, PFI must prove by clear and convincing evidence that:
1) Normark “acted despite an objectively high likelihood that its actions constituted infringement
of a valid patent”; and 2) Normark acted with specific intent, because the objectively-defined
risk was “either known or so obvious that it should have been known” to Normark. In re
Seagate Tech., LLC, 497 F.3d 1360, 1371 (Fed. Cir. 2007) (en banc). The objective prong of the
Seagate test is a question of law for the court. Bard Peripheral Vascular, Inc. v. W.L. Gore &
Associates, Inc., 682 F.3d 1003, 1006-07 (Fed. Cir. 2012).
40
The first prong of the Seagate test is to be “determined by the record developed in the
infringement proceeding.” Seagate, 497 F.3d at 1371. “If the accused infringer’s position is
susceptible to a reasonable conclusion of no infringement, the first prong of Seagate cannot be
met.” Uniloc USA, Inc. v. Microsoft Corp., 632 F.3d 1292, 1310 (Fed. Cir. 2011). “[B]oth
legitimate defenses to infringement claims and credible invalidity arguments demonstrate the
lack of an objectively high likelihood that a party took actions constituting infringement of a
valid patent.” Black & Decker, Inc. v. Robert Bosch Tool Corp., 260 F. App’x 284, 291 (Fed.
Cir. 2008). The query into whether an accused infringer has raised a substantial question for its
defense is independent of whether a jury might ultimately reject that defense. See, e.g., Spine
Solutions, Inc. v. Medtronic Sofamor Danek USA, Inc., 620 F.3d 1305, 1319 (Fed. Cir. 2010).
Given the court’s grant of summary judgment in favor of Normark on Normark’s
invalidity defenses, the court finds that the issue of willful infringement is moot. Alternatively,
the court finds that Normark is entitled to summary judgment of no willful infringement, because
Normark has credible invalidity defenses.

VI.
PFI’S MOTION FOR SUMMARY JUDGMENT
INEQUITABLE CONDUCT COUNTERCLAIM
ON
NORMARK’S
To prevail on its inequitable conduct counterclaim, Normark has the burden of proving,
by clear and convincing evidence, that the patentee made a material misrepresentation or
omission, and that the patentee acted with intent to deceive the PTO. Therasense, Inc. v. Becton,
Dickinson & Co., 649 F.3d 1276 (Fed. Cir. 2011) (en banc); Ring Plus, Inc. v. Cingular Wireless
Corp., 614 F.3d 1354, 1358 (Fed. Cir. 2010). With respect to materiality, Normark must show
that the misrepresentation or omission meets the standard of “but-for” materiality, meaning that
the ‘214 patent would not have issued but for the misrepresentation or omission. There is an
exception to this requirement for affirmative egregious misconduct. Therasense, 649 F.3d at
1292. With respect to deceptive intent, to meet the clear and convincing standard of proof,
specific intent to deceive must be the single most reasonable inference able to be drawn from the
evidence. Therasense, 649 F.3d at 1290-91. Because direct evidence of deceptive intent is rare,
a district court may infer intent from indirect and circumstantial evidence. Id.
The court is the finder of fact on Normark’s inequitable conduct counterclaim. “The
defense of inequitable conduct is entirely equitable in nature, and thus not an issue for the jury to
decide.” PerSeptive Biosys., Inc. v. Pharmacia Biotech, Inc., 225 F.3d 1315, 1318 (Fed. Cir.
2000); see also Am. Calcar, Inc. v. Am. Honda Motor Co., Inc., 651 F.3d 1318, 1333 (Fed. Cir.
2011). To be entitled to summary judgment, PFI must show that there are no genuine issues of
material fact concerning the issues of materiality and intent raised by Normark’s inequitable
conduct counterclaim.
The court concludes that PFI is not entitled to summary judgment on Normark’s
inequitable conduct counterclaim. For the reasons explained above, there is sufficient evidence
to support the first prong of Normark’s claim, that material information was withheld from the
42
patent examiner. In particular, Cook’s affirmative statement that he was the sole inventor was
necessarily a failure to disclose that he was not. This non-disclosure was material because the
patent would not have issued had Cook disclosed this information.
The failure to disclose that 1995 Fireline Fused had been on sale for more than a year
before the ‘214 patent application was also material, as the patent would not have issued had the
Patent Office been advised of 1995 Fireline Fused. It is also material to obviousness because the
‘214 patent claims were, at the least, obvious in light of 1995 Fireline Fused, as discussed above.
This product also provided a bridge between the inventions in Hogenboom and Dunbar and
application of those inventions to fishing line.
With respect to obviousness, it is also of particular concern that the original denial of the
patent was overcome in part by argument by counsel for PFI that there was no prior art which
would bridge the gap between the rope-making process in Hogenboom and the process for
fishing line addressed in the application which became the Cook ‘214 patent. See Dkt. No. 2079, at p. 10. PFI could not have made this argument if sales of 1995 Fireline Fused had been
disclosed.
Materiality is also supported by the fact that most of the distinctions the examiner
found between the ‘214 patent and Hogenboom would have been satisfied by the process used to
make 1995 Fireline Fused, thus defeating the grounds on which the examiner concluded the ‘214
patent could issue over Hogenboom. This and other evidence cited by Normark supports a
finding that material information was withheld.
Intent is the more challenging prong for Normark, particularly under the Federal Circuit’s
more recent decisions. There is, however, sufficient circumstantial evidence of intent to mislead
to raise a genuine issue of material fact for trial. For example, Cook would have known at the
time he signed his statement claiming to be the inventor of the contributions of DSM. Cook was
43
certainly also aware of 1995 Fireline Fused, as he testified that he set its production parameters.
This evidence of knowledge, coupled with Cook’s involvement in the application process,
including reviewing counsel’s arguments in response to the initial denial, is circumstantial
evidence of an intent to deceive.
It is also significant that the same attorney, Lance Johnson, prepared and prosecuted the
two Fireline applications, both of which were filed before the application for the ‘214 patent.
This involvement in prosecution of all three patents is at least circumstantial evidence of
knowledge of the status of 1995 Fireline Fused. This is not all of the evidence the court has
considered on the issue of intent, but it is sufficient to demonstrate that there are genuine issues
of material fact precluding summary judgment.
CONCLUSION
For the reasons set forth above:
1.
Normark’s motion for summary judgment that claims 1, 4, and 5 of the ‘214
patent are invalid under Section 102(f) is granted;
2.
Normark’s motion for summary judgment that claims 1, 4, and 5 of the ‘214
patent are invalid under Section 102(b) because of 1995 Fireline Fused is granted;
3.
Normark’s motion for summary judgment that claims 1, 4, and 5 of the ‘214
patent are invalid under Section 102(b) because of the Dunbar Patent is denied;
4.
Normark’s motion for summary judgment that claims 1, 4, and 5 of the ‘214
patent are invalid as obvious under Section 103 is granted;
5.
The court need not decide Normark’s motion for partial summary judgment of no
infringement, because the parties’ stipulation on the issue of infringement has made that motion
moot;
44
6.
Normark’s motion for summary judgment of no willful infringement is made
moot by the court’s rulings on the validity of the ‘214 patent, and, alternatively, Normark’s
motion for summary judgment of no willful infringement is granted;
7.
The court also need not decide Normark’s motion for summary judgment on
PFI’s claim for damages, as that issue is made moot by the court’s rulings herein;
8.
For the same reason, the court will not decide Normark’s motion in limine to
exclude the testimony of PFI’s damages expert, Hugh Penny;
9.
The court need not decide PFI’s motion for partial summary judgment of
infringement, because the parties’ stipulation on the issue of infringement has made that motion
moot; and
10.
The court denies PFI’s motion for summary judgment on Normark’s inequitable
conduct counterclaim.
