MEMORANDUM OPINION AND ORDER
Plaintiff Scholle Corporation moved for a preliminary injunction against Defendant
Rapak LLC based on Rapak’s alleged infringement of U.S. Patent No. 8,448,799. The ’799
Patent discloses a self-sealing bag in box cap assembly. Scholle claims that its QuickSeal Sentry
Lock fitment, which is a valve used to attach flexible bags such as those used in liquid fruit and
dairy products to serve smoothie beverages in major restaurant chains, is an embodiment of the
’799 Patent. Although Scholle has been in the market for many years, Scholle touts its QuickSeal
Sentry Lock as a relatively new innovation. Scholle obtained its patent on May 28, 2103, the day
before this suit was filed. On January 9, 2014, this Court conducted a factual hearing to allow the
parties to present evidence and arguments in support of their respective positions. For the reasons
stated herein, this Court grants Scholle’s motion for preliminary injunction and enjoins Rapak
from making, using, selling, or offering to sell in the United States the accused product, Rapak’s
Smoothie Valve, or products that include Rapak’s Smoothie Valve as a component.
LEGAL STANDARD
Federal Rule of Civil Procedure 65 allows courts to issue preliminary injunctions to
prevent harm to one or more parties before the parties have fully adjudicated their claims. A
preliminary injunction is an extraordinary remedy that requires a clear showing that one is
entitled to such a remedy. LifeScan Scotland, Ltd. v. Shasta Technologies., LLC, 734 F.3d 1361,
1366 (Fed. Cir. 2013). Because Scholle seeks to enjoin Rapak’s alleged patent infringement,
Federal Circuit precedent controls. Revision Military, Inc. v. Balboa Mfg. Co., 700 F.3d 524, 525
(Fed. Cir. 2012). “A plaintiff seeking a preliminary injunction must establish that he is likely to
succeed on the merits, that he is likely to suffer irreparable harm in the absence of preliminary
relief, that the balance of equities tips in his favor, and that an injunction is in the public
interest.” Id. (quoting Winter v. Natural Res. Def. Council, Inc., 555 U.S. 7, 22 (2008)). In an
action for patent infringement, a plaintiff cannot meet his burden where the accused infringer
raises a substantial question as to infringement or invalidity. LifeScan, 734 F.3d at 1366.

Scholle is Likely to Succeed on the Merits
1.
Claim Construction
“A correct claim construction is almost always a prerequisite for imposition of a
preliminary injunction.” Chamberlain Group, Inc. v. Lear Corp., 516 F.3d 1331, 1340 (Fed. Cir.
2008). At issue here is claim 1 of the ’799 Patent. The claim discloses a cap assembly. In its
pleadings and at the preliminary injunction hearing, Rapak identified two terms in claim 1 of the
’799 Patent that it believes require construction. These terms are “top surface” and “releasably
sandwich.” This Court construes those claims for purposes of the pending preliminary injunction
motion. See Outside the Box Innovations, LLC v. Travel Caddy, Inc., 695 F.3d 1285, 1302 (Fed.
Cir. 2012) (“the general rule is that tentative claim construction for preliminary injunction
purposes does not remove the issue from later review after the facts are elaborated”).
2
The parties’ dispute whether an inwardly sloping surface on the accused product is part of
the “top surface” or the “inner surface” of the cap assembly. If the former, then Rapak argues
that it does not infringe; if the latter, then Scholle argues that Rapak infringes. But “[c]laims are
properly construed without the objective of capturing or excluding the accused device.” Vita-Mix
Corp. v. BasicHolding, Inc., 581 F.3d 1317, 1324 (Fed. Cir. 2009). Therefore, this Court will not
consider the accused product when construing the claim term.
Instead, this Court must focus primarily on the language of the claim. Aria Diagnostics,
Inc. v. Sequenom, Inc., 726 F.3d 1296, 1300 (Fed. Cir. 2013). Here, the claim identifies the “top
surface” as part of the body of the cap assembly and generally defines where the “top surface” is
in relation to other claim limitations; but it does not define or otherwise suggest what the “top
surface” is. (Dkt. 20-2 at 5:13-6:8.)
Accordingly, this Court turns to the specification, which is often fundamental to claim
construction. Trading Techs. Int’l, Inc. v. Open E Cry, LLC, 728 F.3d 1309, 1319 (Fed. Cir.
2013) (“The specification is fundamental to claim construction, as ‘it is the single best guide to
the meaning of a disputed term.’ ”) (quoting Phillips v. AWH Corp., 415 F.3d 1303, 1315 (Fed.
Cir. 2005) (en banc)). Here, the specification distinguishes the “top surface” from the other parts
of the body of the cap assembly: the “bottom surface” and the “opening.” (Dkt. No. 20-2 at 3:810.) As used in the ’799 Patent, each of these terms take their plain and ordinary meaning as
understood by a person of ordinary skill in the art.
In their pleadings and at the hearing, neither party attempted to define a person of
ordinary skill. The only reference this Court found regarding the level of skill in the art was in
Rapak’s invalidity contentions. (Dkt. No. 37-30 at 6, n.1.) This Court accepts Rapak’s definition
for purposes of this motion. Rapak believes, at least for now, that a person of ordinary skill in the
3
art would have a degree in mechanical engineering with two to three years of experience in valve
design and materials or a person having equivalent work experience in the field. This person, as
would most others reading the ’799 Patent, would understand “top surface” to mean the upper
side of the assembly, “bottom surface” to mean the underside of the cap assembly, and
“opening” to mean the aperture in the center of the cap assembly.
Contrary to Scholle’s suggestion, the “top surface” does not have to exist on a single
plane. The specification indicates that the “top surface” may include a circumferential cap
sealing flange:
The top surface includes circumferential cap sealing flange 56. The
circumferential cap sealing flange 56 is typically employed when
cap 46 is utilized. The cap 46 includes a similar sealing flange 56
which together with the cap sealing flange 56 provides a hermetic
seal when engaged. In embodiments wherein a membrane seal is
utilized, the sealing flange can be omitted, and the membrane seal
can be sealed against the circumferential sealing surface 57 which
is outboard of the location of the cap sealing flange.
(Dkt. No. 20-2 at 3:19-27.) As used in the ’799 Patent, a flange is a rim or a lip that projects from
a surface. (See id. at 3:19-23 and 3:47-50.) Because the top surface can include a circumferential
cap sealing flange that projects from the surface, it can have multiple levels. The inclusion of a
spout engagement channel, which has multiple levels, as part of the “bottom surface” supports
this conclusion.
That does not address the real issue, which is where does the “top surface” end and the
“opening” begin? The specification defines the “opening” as “comprising inner surface 64 and
membrane engaging flange 66 positioned at the lower end thereof.” (Id. at 3:42-44.) The “inner
surface” has several components, to include a recessed circumferential channel, a base channel,
and a membrane engaging surface that is at the lower end of the opening. (Id. at 3:44-50.) The
specification, to include Figures 3 and 4, indicate that the transition point between the “top
4
surface” and the “opening” is where the horizontal plane of the “top surface” descends toward
the “bottom surface.” When there is a circumferential cap sealing flange, that descent begins at
the inner edge (closest to the center of the opening) of it. The specification does not indicate
whether this descent is a vertical one; therefore, the descent may slope as well. Because the
invention must accommodate a retaining ring and a sealing membrane in the opening, the part of
the body of the cap assembly that receives the retaining ring and sealing membrane is part of the
opening. Therefore, the top surface ends and the opening begins where the innermost horizontal
plane of the top surface begins its descent toward the bottom of the cap assembly.
Rapak also takes issue with the claim term “releasably sandwich.” But Rapak does not
propose a construction for the term. Instead, Rapak argues that the inventors added the term to
the specification during prosecution to avoid prior art and that the term cannot apply to Rapak’s
product because removing its retaining ring would cause the product to leak. Scholle argues for
the plain and ordinary meaning of the term, and cites the dictionary as an example of the
meaning of the word sandwich. This Court agrees with Scholle that the claim term “releasably
sandwich” takes its plain and ordinary meaning.
2.
Infringement
Scholle has established that it is likely to succeed on the merits of its claim for patent
infringement and Rapak has not raised a substantial question as to infringement. To determine
whether an accused product infringes a patent claim, one must first construe the patent claim and
then compare the properly construed claim to the accused product. Meyer Intellectual Properties,
Ltd. v. Bodum, Inc., 690 F.3d 1354, 1366 (Fed. Cir. 2012). “Literal infringement requires that
each and every limitation set forth in a claim appear in an accused product.” V-Formation, Inc. v.
Benetton Group SpA, 401 F.3d 1354, 1366 (Fed. Cir. 2012).
5
At issue here is claim 1 of the ’799 Patent. Scholle has presented evidence that the
accused product embodies each claim limitation. Rapak admits that it meets all but the following
limitations of claim 1:
a body having a top surface and a bottom surface, a spout
engagement channel on the bottom surface thereof and an inner
surface defining an opening extending therethrough (“the channel
limitation”);
the opening including a recessed circumferential channel molded
into the inner surface and spaced apart from the top surface and a
membrane engaging flange positioned proximate the recessed
circumferential channel, such that the recessed circumferential
channel is positioned between the top surface and the membrane
engaging flange (“the opening limitation”);
and a retaining ring positioned entirely within the confines of the
inner surface and below the top surface of the body (“the confines
limitation”); and
the retaining ring positioned with the sealing membrane engaging
surface in the overlying engagement with the sealing membrane,
with the body engaging tab extending into the recessed
circumferential channel of the body to releasably sandwich, in
sealed engagement, the body engagement flange of the sealing
membrane between the sealing membrane engagement surface of
the retaining ring, and the membrane engaging flange of the body
(“the releasably sandwich limitation”).
(Dkt. No. 37-30 at 2-4.)
Rapak’s challenges to Scholle’s infringement contentions fail. Scholle marked an accused
product as Exhibit P. An examination of Exhibit P refutes Rapak’s argument that it does not
meet the channel limitation. There is a groove on the bottom surface of the accused product that
likely satisfies the channel limitation. The same is true for the opening limitation, as Exhibit P
includes a recessed channel in its opening that is offset by vertical surfaces on either side. These
vertical surfaces distance the recessed channel from the top surface and membrane engaging
flange.
6
Rapak argues that it does not meet the confines limitation because its retaining ring
extends above the top surface of its product. The accused product does not have a circumferential
cap sealing flange. Rather, a sloping surface denotes the transition from the top surface to the
opening. That sloping surface is a downward slope that runs from the horizontal top surface to
the mostly vertical inner surface. Based on this Court’s construction of the term “top surface,”
the downward sloping surface is part of the opening and not the top surface. In short, the
retaining ring and sealing membrane enter the body of the cap assembly at the point where
downward sloping surface begins. Although Rapak’s retaining ring extends above the bottom
edge of the sloping surface, it does not extend above the top edge, which is where the top surface
is. Therefore, the accused product likely satisfies this limitation.
Finally, Rapak argues that the accused product does not meet the releasably sandwich
limitation. Rapak argues that its retaining ring is mechanically bonded—not releasably
sandwiched. But Scholle demonstrated that the sealing membrane of the accused product is
between its retaining ring and the membrane engaging flange. At the hearing, Scholle established
that one could remove the retaining ring by hand and then re-insert it. Rapak argues that the
product may leak after one forcefully removes the retaining ring from the accused product, but
the claim does not require a leak-free product. It requires a membrane sandwiched between two
components, which the accused product has. Therefore, this Court finds that Scholle is likely to
prevail on infringement.
3.
Invalidity
Scholle has established that Rapak’s challenges to the validity of claim 1 of the ’799
Patent lack substantial merit. The Court begins this analysis with the understanding that the ’799
Patent enjoys a presumption of validity under 35 U.S.C. § 282. In its opposition to Scholle’s
motion, Rapak challenges claim 1 on three grounds: (1) improper inventorship; (2) anticipation;
7
and (3) obviousness. Rapak primarily relies on four prior art references: 1) U.S. Patent No.
5,377,877 to Brown; 2) U.S. Patent No. 5,938,086 to Gross; 3) U.S. Patent No. 7,861,393 to
Pugne; and 4) U.S. Patent Publication No. 2010/0193516 to LaBean. Based on the evidence
presented, none of these challenges raises a substantial question of validity.
A patent must accurately list the correct inventors of the claimed invention. Checkpoint
Sys., Inc. v. All-Tag Sec. S.A., 412 F.3d 1331, 1337-38 (Fed. Cir. 2005). To render a patent
invalid on this ground, one must show by clear and convincing evidence that the inventors
named in a patent are incorrect. Id. According to Rapak, the ’799 Patent should also include
individuals who identified a problem with the named inventors’ early design as inventors. But
there is no evidence that those individuals significantly contributed to the conception and
reduction to practice of the claimed invention. Instead, those individuals solely informed the
inventors that inserting a probe into the cap assembly caused damage to a valve (Dkt. No. 63,
Hr’g Tr. at 24:2-26:5) and suggested that the inventors modify the retaining ring to prevent that
damage (See Dkt. No. 41-24 at SCHOLLE001819). They did not tell the inventors what
modifications to make. An inventor must contribute to the conception and reduction to practice
of the invention. Nartron Corp. v. Schukra U.S.A. Inc., 558 F.3d 1352, 1356-57 (Fed. Cir. 2009).
Because there is no evidence that anyone other than the inventors contributed to the design
modification, Rapak has not raised a substantial question as to inventorship.
The design modification, however, precludes claim 1 of the ’799 Patent from claiming
priority to a provisional patent application filed in 2008. Although the provisional patent
application disclosed a cap assembly, the retaining ring in that cap assembly was “substantially
triangular in configuration.” (Dkt. No. 46-10 at RAP000182.) Though not limited to this
embodiment, the provisional application does not refer to a retaining ring having “an inwardly
8
sloping protective flange” as claimed in claim 1 of the ’799 Patent. (Compare id. with Dkt. No.
20-2 at 5:41-43.) Based on the evidence presented to this Court, the inventors added “an
inwardly sloping protective flange” sometime after March 10, 2009, which is when a
memorandum discussed the valve problem and a suggestion to fix it (Dkt. No. 41-24 at
SCHOLLE001819), and March 19, 2009, which is the date of a memorandum that describes and
depicts the modification made in response to the valve damage problem (Dkt. No. 41-25 at
SCHOLLE000570).
Although the parties dispute whether all of the references identified by Rapak are prior
art to claim 1 of the ’799 Patent, this Court will treat all four references as prior art for purposes
of this motion. Rapak argues that two of those references, Pugne and LaBean, anticipate claim 1
of the ’799 Patent. To anticipate a claim, a single prior art reference must expressly or inherently
disclose each and every element of the claim. Whitserve, LLC v. Computer Packages, Inc. 694,
F.3d 10, 22 (Fed. Cir. 2012). As Scholle correctly notes, LaBean does not expressly or inherently
disclose a spout engagement channel. The exterior surface in LaBean that Rapak argues meets
this limitation does not have an outer flange as disclosed in the ’799 Patent. The same is true for
Pugne. Therefore, Rapak has not raised a substantial question as to anticipation.
Nor has Rapak raised a substantial question as to whether the LaBean, Pugne, Gross, and
Brown references, alone or in combination, render claim 1 of the ’799 Patent obvious. A patent
claim is invalid as obvious “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 having ordinary skill in the art.” Celsis In Vitro, Inc. v.
CellzDirect, Inc., 664 F.3d 922, 928 (Fed. Cir. 2012) (quoting 35 U.S.C. § 103). To determine
whether a patent claim is invalid as obvious, one must consider the following underlying factual
9
inquiries: “(1) the scope and content of the prior art; (2) the level of ordinary skill in the art; (3)
the differences between the claimed invention and the prior art; and (4) objective evidence of
nonobviousness.” Celsis In Vitro, 664 F.3d at 928.
The scope and content of the prior art presented by the parties include the LaBean,
Pugne, Gross, and Brown references. According to Rapak, the level of ordinary skill in the art
requires a degree in mechanical engineering with two to three years of experience in valve
design and materials or a person having equivalent work experience in the field. The differences
between the prior art and the claimed invention include not only LaBean and Pugne’s lack of
spout engagement channels but also their lack of inwardly sloping protective flanges. Rapak
points to what appears to be chamfers in the LaBean and Pugne references as inwardly sloping
protective flanges. The Court disagrees with Rapak’s view. Though the chamfers may serve to
guide a probe or to soften a hard edge, they do not appear to be “protective” in the sense used in
the ’799 Patent.
Even if the four references Rapak cites collectively disclosed all limitations of claim 1 of
the ’799 Patent, Rapak did not offer any evidence as to why a person having ordinary skill in the
art would have combined the references. One cannot show that a patent is obvious without
evidence as to why a person having ordinary skill in the art would have combined the references
to arrive at the claimed invention. Kinetic Concepts, Inc. v. Smith & Nephew, Inc., 688 F.3d
1342, 1366-67. This reason can come from a number of sources to include the knowledge and
skill of a person of ordinary skill in the art. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 420
(2007) (“Common sense teaches, however, that familiar items may have obvious uses beyond
their primary purposes, 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.”) Rapak has not offered any
10
evidence as to what a person of ordinary skill in the art would have gleaned from the four
references Rapak cites. Instead, Rapak relies exclusively on attorney argument. That is
insufficient. Contra ArcelorMittal France v. AK Steel Corp., 700 F.3d 1314, 1324 (Fed. Cir.
2012) (expert testimony that a person of ordinary skill in the art would have had the knowledge
to combine prior art teachings provided evidence to support reason to combine). There is no
evidence from which this Court can determine what a person having ordinary skill in the art
would have known. Therefore, based on this preliminary record, Rapak has not raised a
substantial question as to whether claim 1 of the ’799 Patent is obvious.
B.
Irreparable Injury
Scholle has shown that it will likely suffer irreparable injury absent an injunction. To
establish irreparable harm in an action for patent infringement, a plaintiff must not only show
that it will suffer irreparable harm but also establish a sufficiently strong causal nexus between
the irreparable harm and the alleged infringement. Apple Inc. v. Samsung Electronics Co., Ltd.,
695 F.3d 1370, 1374 (Fed. Cir. 2012). “[T]he irreparable harm inquiry seeks to measure harms
that no damages payment, however great, could address.” Celsis in Vitro, 664 F.3d at 930. “Price
erosion, loss of goodwill, damage to reputation, and loss of business opportunities are all valid
grounds for finding irreparable harm.” Id.
Here, Scholle has shown that competition with Rapak likely has led to a loss of market
share and price erosion. Based on the evidence presented, there are two or three suppliers for cap
assemblies in the market at issue. Thus, Scholle and Rapak are direct competitors. Since May 28,
2013, Scholle has lost sales to the accused product. (Dkt. No. 20-1 at 6.) And Rapak sells the
accused product at a lower price than Scholle, which has exerted, and continues to exert,
downward pressure on Scholle’s price.
(Id. at 7.) Loss of market share and price erosion can
constitute evidence of irreparable harm when determining whether a preliminary injunction
11
based on patent infringement should issue. See Abbott Laboratories v. Sandoz, Inc., 544 F.3d
1341, 1361-62 (Fed. Cir. 2008); Bio-Technology Gen. Corp. v. Genentech, Inc., 80 F.3d 1553,
1556 (Fed. Cir. 1996).
Further, Rapak is in no position to argue that the patented features do not drive sales of
the cap assemblies at issue. The evidence presented shows that Scholle designed its cap assembly
for use by a particular customer. According to Rapak, that customer not only insisted on one
patented feature but also contributed to its invention. Given this design history, there is a strong
causal nexus between the harm caused by Rapak’s product, which incorporates that feature and
is sold to that customer, and the alleged infringement. Therefore, Scholle has shown that Rapak’s
likely infringement will likely result in irreparable injury to Scholle.
C.
Balance of Equities and Public Interest
This Court finds that the balance of equities tips slightly in Scholle’s favor. Scholle is the
patentee and has shown that it will likely prevail on the merits. Scholle argues that Rapak is a
direct competitor that is using Scholle’s patented technology to Scholle’s detriment. Rather than
identify any hardship it may suffer if an injunction issues, Rapak simply argues that Scholle will
not prevail on the merits. Although Rapak does not argue it, it will likely lose sales if it can no
longer sell the accused product. Even so, that does not outweigh Scholle’s interest in enforcing
its patent rights, which is in line with the public interest. Therefore, this Court finds that the
balance of equities and the public interest favor Scholle, albeit slightly.
12
CONCLUSION
For the reasons stated herein, this Court grants Scholle’s motion for a preliminary
injunction. This Court directs the parties to submit a three-page position paper concerning the
appropriate bond Scholle should post under Fed. R. Civ. P. 65(c). The parties may attach
supporting documentation to their submission, as necessary.
