UNITED STATES DISTRICT COURT
DISTRICT OF MINNESOTA
Spineology, Inc.,
Plaintiff,
v.
Case No. 15-cv-180 (JNE/FLN)
ORDER
Wright Medical Technology, Inc.,
Defendant.
Spineology, Inc., brought this action against Wright Medical Technology, Inc., for
infringement of United States Reissued Patent No. RE42,757 (filed May 7, 2004).
Wright Medical Technology asserted counterclaims for declarations of noninfringement,
absolute and equitable intervening rights, and invalidity. The case is before the Court on
Spineology’s Motion for Summary Judgment, Wright Medical Technology’s Motion for
Summary Judgment, and Wright Medical Technology’s motions to exclude certain
opinions of Spineology’s experts. For the reasons set forth below, the Court grants
Wright Medical Technology’s Motion for Summary Judgment and denies the remaining
motions.
I.
BACKGROUND
The invention claimed in the ’757 Patent “relates to an expandable reamer for use
in surgery, particularly in orthopedic applications.” ’757 Patent col. 1 ll. 25-26. “The
invention provides a surgical tool . . . for forming hollow chambers within bone that are
larger in diameter than the external opening into the chamber. The tool has a distal end
with external dimensions sized to be passed through the patient’s anatomy to a point of
1
entry into the bone.” ’757 Patent col.1 ll. 60-64. Retractable blades may “be extended to
cut a cavity greater than the diameter of the surgical tool.” ’757 Patent col. 1 ll. 64-67.
The ’757 Patent describes two preferred embodiments. Figures 1 and 2 of the
’757 Patent, which appear below, depict one. It includes a hollow main shaft 136 that
carries an elongated shaft 140 and blade guides 150 and 152. Blades 142 and 144 are
mounted at the distal end of the elongated shaft. The main shaft is attached to a guide
member that is inserted into an opening in a blade advancer barrel 138. The end of the
guide member includes a threaded shaft 190 that is received within the barrel by a blade
advancer knob 194. The guide member includes a pin 212. Observation of the pin within
an opening 232 on the barrel’s slide door 214 allows a user to track the degree of
movement that the shaft makes as the knob is turned. Rotation of the knob causes the
main shaft and blade guides to move inwardly or outwardly within the barrel. The
2
elongated shaft remains stationary. The blades move as their engagement members move
within slots 158 on the blade guides. ’757 Patent col. 2 1.48 to col. 3 1.61.
Figures 10 and 11 of the ’757 Patent display views of the reamer according to an
alternative embodiment. “[A]n elongated tube and barrel 100 carry a long rod 92 that
3
attaches at the proximal end to a turn wheel 96 that moves the blades distally and
proximally. The end of the long rod 92 is attached to two like blades by a pivot 118 that
allows the blades 114 and 116 to change position.” ’757 Patent col. 4 ll. 2-7. “The
surgeon may visualize the degree the blades 114 and 116 extend by viewing the position
of the shaft 92 relative to the barrel 102, through view port 107.” ’757 Patent col. 6 ll.
49-51. Although figures 10 and 11, as well as figure 13, display the view port 107 on the
barrel 102, the written description states that “[t]urn wheel 96 may include depth marking
slot 107 which allows the user to see how far the blades have extended or retracted.”
’757 Patent col. 4 ll. 57-59.
The ’757 Patent is a reissue of United States Patent No. 6,383,188 (filed Feb. 13,
2001). There were 14 claims in the ’188 Patent. In May 2004, a reissue application was
filed. In September 2011, the prosecution of the reissue application concluded with the
4
issuance of the ’757 Patent. Of the ’188 Patent’s 14 claims, only claim 13 remained in
the ’757 Patent. Claims 1-12 and 14 were canceled in the course of the prosecution of the
reissue application. In addition to claim 13, the ’757 Patent contains claims 15-43, which
were added during the prosecution of the reissue application.
Spineology asserted that Wright Medical Technology infringes independent claims
15, 33, and 35; claims 21-23, which depend on claim 15; and claim 34, which depends on
claim 33. The accused product is Wright Medical Technology’s X-Ream percutaneous
expandable reamer. The asserted claims appear below. The Court previously determined
that “activation mechanism” in claims 15 and 35 is indefinite.
Claim 15
An expandable reamer for use in bone and related tissue in a mammal comprising:
an elongated hollow body having a proximal end and a distal end, sized and
configured to engage bone and related tissue in the mammal;
an elongated blade carrier having a proximal end and a distal end, the blade
carrier disposed within the body;
a set of blades pivotally attached proximate the distal end of the blade
carriers; the set of blades having at least a first retracted position relative to
the body, the body having a maximum cross-sectional diameter transverse
to a longitudinal axis of the body that is substantially at least as large as a
maximum cross-sectional diameter of the blades in the first retracted
position, and a second fully expanded position having a diameter greater
than the maximum cross-sectional diameter of the body; and
an manually actuated activation mechanism that moves the set of blades
from the first retracted position to the second fully expanded position and
any expanded position therebetween.
Claim 21
The reamer of claim 15 wherein the blades extend beyond the distal end of the
hollow body.
5
Claim 22
The reamer of claim 15 wherein the blades are pivotally attached at a single pivot
point.
Claim 23
The reamer of claim 15 wherein each of the blades includes a cutting portion
arranged such that substantially all of the cutting portion is outside the maximum crosssectional diameter of the body when the blades are in the second fully expanded position.
Claim 33
A method for creating a cavity in bone comprising:
drilling a bore in bone,
inserting an expandable reamer into the bore,
manually actuating an activation mechanism of the reamer that engages a
blade carrier within the reamer such that linear motion of the blade carrier
drives a blade set pivotally attached to the blade carrier from a first
retracted position relative to the body, the body having a maximum crosssectional diameter transverse to a longitudinal axis of the body that is
substantially at least as large as a maximum cross-sectional diameter of the
blades in the retracted position to a second fully expanded position having a
diameter greater than the maximum cross-sectional diameter of the body
and any expanded position therebetween;
contacting the bone with the blade set in the any expanded position; and
rotating the expandable reamer such that the blade set cuts into the bone.
Claim 34
The method of claim 33 wherein the blades extend beyond the distal end of the
hollow body.
Claim 35
An expandable reamer for use in bone and related tissue in a mammal comprising:
an elongated hollow body having a proximal end and a distal end sized and
configured to engage bone and related tissue in the mammal;
6
at least one shaft operably arranged in a coaxial relation with the hollow
body along a longitudinal axis and having a proximal and a distal end;
a set of blades pivotally attached proximate the distal end of the shaft, the
set of blades having at least a first retracted position relative to the body,
the body having a maximum cross-sectional diameter transverse to a
longitudinal axis of the body that is substantially at least as large as a
maximum cross-sectional diameter of the blades in the first retracted
position, and a second fully expanded position having a diameter greater
than the maximum cross-sectional diameter of the body; and
an manually actuated activation mechanism that moves the set of blades
from the first retracted position to the second fully expanded position and
any expanded position therebetween.

DISCUSSION
Motions for summary judgment
Summary judgment is proper “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). To support an assertion that a fact cannot be or is genuinely disputed, a
party must cite “to particular parts of materials in the record,” show “that the materials
cited do not establish the absence or presence of a genuine dispute,” or show “that an
adverse party cannot produce admissible evidence to support the fact.” Fed. R. Civ. P.
56(c)(1)(A)-(B). “The court need consider only the cited materials, but it may consider
other materials in the record.” Fed. R. Civ. P. 56(c)(3). In determining whether
summary judgment is appropriate, a court must view genuinely disputed facts in the light
most favorable to the nonmovant, Ricci v. DeStefano, 557 U.S. 557, 586 (2009), and
draw all justifiable inferences from the evidence in the nonmovant’s favor, Anderson v.
Liberty Lobby, Inc., 477 U.S. 242, 255 (1986).

1.
Wright Medical Technology’s motion
Wright Medical Technology moved for summary judgment of noninfringement of
claims 33 and 34 of the ’757 Patent. According to Wright Medical Technology, “body”
in the ’757 Patent refers to a shaft and a barrel. Wright Medical Technology maintained
that the X-Ream does not infringe because the diameter of the blades of the X-Ream in
their fully expanded position is less than the maximum cross-sectional diameter of the
body. According to Spineology, “body” in the ’757 Patent refers to a shaft alone.
Spineology asserted that the diameter of the blades of the X-Ream in their fully expanded
position is greater than the maximum cross-sectional diameter of the body.
An infringement analysis has two steps. First, the court determines the meaning
and scope of the claims asserted. Tinnus Enters., LLC v. Telebrands Corp., 846 F.3d
1190, 1203 (Fed. Cir. 2017); Grober v. Mako Prods., Inc., 686 F.3d 1335, 1344 (Fed. Cir.
2012). Second, the court compares the properly construed claims to the allegedly
infringing device. Tinnus Enters., 846 F.3d at 1203; Grober, 686 F.3d at 1344. Claim
construction is a question of law, and infringement is a question of fact. Monsanto Co. v.
Syngenta Seeds, Inc., 503 F.3d 1352, 1356 (Fed. Cir. 2007).
The Court previously addressed the construction of disputed claim terms,
including “body.” Spineology asserted that “body” should be construed as “the tube or
shaft in which the blade carrier is housed,” and Wright Medical Technology maintained
that “body” should be construed as “outer structure(s) of the reamer.” Later, Wright
Medical Technology proposed “outer structure(s) that house internal components.” The
Court considered the use of “body” in claim 15 and its dependent claims to be illustrative,
8
found no description of any part of the reamer that used “body” in the written description,
summarized the preferred embodiments, assessed the parties’ proposed constructions,
declined to adopt either party’s proposed construction of “body,” stated that the claims
themselves provide substantial guidance as to the meaning of the term, and discerned no
need to construe the term except to state that “body” does not include the blade control
knob.
Claim 15 recites “an elongated hollow body” that has “a proximal end and a distal
end, sized and configured to engage bone and related tissue in the mammal.” The blade
carrier is “disposed within the body.” A set of blades is “pivotally attached proximate the
distal end” of the blade carrier. The set of blades has “a first retracted position relative to
the body” and “a second fully expanded position having a diameter greater than the
maximum cross-sectional diameter of the body.” The body has “a maximum crosssectional diameter transverse to a longitudinal axis of the body that is substantially at
least as large as a maximum cross-sectional diameter of the blades in the first retracted
position.” Claim 16, which depends on claim 15, recites that “the body includes a view
port.” Claim 17, which depends on claim 15, recites that “the blade carrier is linearly
moveable relative to the body and the body includes indicators that indicate a distance
that the blade set is extended from the distal end of the body.” Claim 18, which depends
on claim 15, recites that “the activation mechanism is a moveable cannulated shaft having
linear movement along the body.” Claim 20, which depends on claim 18, recites that
“the activation mechanism is a blade control knob constrained within the proximal end of
the body.” Claim 21, which depends on claim 15, recites that “the blades extend beyond
9
the distal end of the hollow body.” Claim 23, which depends on claim 15, recites that
“each of the blades includes a cutting portion arranged such that substantially all of the
cutting portion is outside the maximum cross-sectional diameter of the body when the
blades are in the second fully expanded position.” The claims that depend on claims 24
and 35 are similar to those that depend on claim 15.
A reading of the claims in the context of the patent reveals that “body” is the
hollow structure that houses the blade carrier and that receives a knob or wheel: “body”
includes the barrel. See Retractable Techs., Inc. v. Becton, Dickinson & Co., 653 F.3d
1296, 1305 (Fed. Cir. 2011) (“It is axiomatic that the claim construction process entails
more than viewing the claim language in isolation. Claim language must always be read
in view of the written description . . . .”); Nystrom v. TREX Co., 424 F.3d 1136, 1149
(Fed. Cir. 2005) (“The district court erred in not properly applying the principles set forth
in our prior precedents that arguments based on drawings not explicitly made to scale in
issued patents are unavailing.”). In each preferred embodiment, the blade carrier is
disposed within an elongated, hollow structure that consists of a tube and a barrel. ’757
Patent col. 3 ll. 34-51; ’757 Patent col. 4 ll. 2-7 (“[A]n elongated tube and barrel 100
carry a long rod 92 that attaches at the proximal end to a turn wheel 96 that moves the
blades distally and proximally.”). The view port is on the barrel. ’757 Patent col. 3 ll.
34-39 (“Observation of the position of the pin 212 within the confines of opening 232
allows a user to track the degree of movement that the shaft 136 makes longitudinally in
response to turning knob 194.”); ’757 Patent col. 6 ll. 49-51 (“The surgeon may visualize
the degree the blades 114 and 116 extend by viewing the position of the shaft 92 relative
10
to the barrel, through view port 107.”). The blade control knob is constrained within the
barrel. ’757 Patent col. 3 ll. 8-10 (“Blade advancer barrel 138 includes an annular recess
200 to mate with knob lip 202 which rotatably secures the knob lip 194 to the barrel
138.”); ’757 Patent col. 3 ll. 40-42; ’757 Patent col. 5 ll. 3-32.
According to an expert witness retained by Wright Medical Technology, the
maximum cross-sectional diameter of the body of the X-Ream is greater than the
maximum cross-sectional diameter of the blades of the X-Ream in their fully expanded
position. Spineology did not direct the Court to any evidence that raises a genuine issue
of material fact. Spineology’s infringement position depends on a claim construction that
the Court previously declined to adopt and that is inconsistent with the claims and the
written description. The Court grants Wright Medical Technology’s motion.
In addition to moving for summary judgment of noninfringement of claims 33 and
34, Wright Medical Technology asserted that summary judgment is appropriate to
establish that Spineology may not recover damages before Wright Medical Technology
received actual notice from Spineology of the ’757 Patent and of Spineology’s
infringement claims. Having concluded that summary judgment of noninfringement is
appropriate, the Court need not consider the parties’ dispute regarding damages.
2.
Spineology’s motion
Spineology moved for summary judgment that there has been direct infringement
of claims 33 and 34 of the ’757 Patent by the use of the X-Ream by an orthopedic
surgeon. Spineology asserted that the limitation in claim 33 regarding the diameter of the
blades in their second fully expanded position—“a second fully expanded position having
11
a diameter greater than the maximum cross-sectional diameter of the body”—is satisfied
“if the body is construed to be that portion of the X-REAM® shaft that is intended to be
inserted into bone, and which would exclude the handle and the barrel.” For the reasons
set forth above, the Court rejects Spineology’s construction. Because there is no
evidence in the record that the blades of the X-Ream in their fully expanded position
have “a diameter greater than the maximum cross-sectional diameter of the body,” the
Court denies Spineology’s motion.
B.
Wright Medical Technology’s motions to exclude
Wright Medical Technology moved to exclude certain opinions and testimony of
Spineology’s expert witnesses. Having concluded that summary judgment in favor of
Wright Medical Technology is appropriate, the Court denies as moot Wright Medical
Technology’s motions to exclude.
C.
Claims and counterclaims
Wright Medical Technology asserted that resolution of its motion for summary
judgment in its favor disposes of the entire case. Spineology’s Complaint contains two
counts, one for patent infringement and the other for willful infringement. Wright
Medical Technology asserted three counterclaims. In Count I, Wright Medical
Technology sought a declaration of noninfringement. In Count II, it sought a declaration
of absolute and equitable intervening rights. In Count III, it sought a declaration of
invalidity.
The Court previously concluded that the means-plus-function limitations of claims
15 and 35 are indefinite. Thus, claims 15 and 35 are invalid. See Intellectual Prop. Dev.,
12
Inc. v. UA-Columbia Cablevision of Westchester, Inc., 336 F.3d 1308, 1319 (Fed. Cir.
2003). Claims 21, 22, and 23, which depend on claim 15, incorporate the same indefinite
limitation of claim 15. They too are invalid. See Ibormeith IP, LLC v. Mercedes-Benz
USA, LLC, 732 F.3d 1376, 1378 (Fed. Cir. 2013); Tele-Publishing, Inc. v. Facebook, Inc.,
219 F. Supp. 3d 237, 238 n.1 (D. Mass. 2016). For the reasons set forth above, summary
judgment of noninfringement of claims 33 and 34 is appropriate. Accordingly, the Court
dismisses Spineology’s infringement claims. See Lazare Kaplan Int’l, Inc. v.
Photoscribe Techs., Inc., 714 F.3d 1289, 1295 (Fed. Cir. 2013) (“[N]o accused products
can be found liable for infringement of an invalid claim.”).
Having concluded that dismissal of Spineology’s infringement claims is
appropriate, the Court declines to issue declarations of noninfringement, absolute
intervening rights, or equitable intervening rights. The Court dismisses without prejudice
Counts I and II of Wright Medical Technology’s counterclaims. As to Count III of the
counterclaims, the Court declares that claims 15, 21, 22, 23, and 35 of the ’757 Patent are
invalid. The Court otherwise dismisses without prejudice Count III of Wright Medical
Technology’s counterclaims. See Liquid Dynamics Corp. v. Vaughan Co., 355 F.3d
1361, 1370-71 (Fed. Cir. 2004) (“A district court judge faced with an invalidity
counterclaim challenging a patent that it concludes was not infringed may either hear the
claim or dismiss it without prejudice, subject to review only for abuse of discretion.”).
