______________________
Before O’MALLEY, CLEVENGER, and STOLL, Circuit
Judges.
STOLL, Circuit Judge.
Ethicon LLC appeals from a final written decision of
the Patent Trial and Appeal Board holding claims 1–14 of
U.S. Patent No. 9,585,658 unpatentable under 35 U.S.C.
§ 102 and denying Ethicon’s contingent motion to amend to
substitute proposed claims 20 and 21. Because we agree
with the Board’s claim construction of relevant terms, and
because substantial evidence supports the Board’s antici-
pation finding under that construction, we affirm the
Board’s determination that claims 1–14 are unpatentable.
Because the Board’s denial of Ethicon’s contingent motion
seeking to substitute proposed claims 20 and 21 was based
on an anticipation finding unsupported by substantial evi-
dence, we reverse that finding and remand for the Board to
consider Intuitive Surgical, Inc.’s alternative grounds for
invalidity of Ethicon’s proposed substitute claims 20 and
21.
BACKGROUND
The ’658 patent generally relates to surgical staplers
having an end effector closing system and a firing system
for deploying staples. The inventive stapling system of the
’658 patent “comprises a housing comprising a rotary drive
member, an elongate shaft extending from the housing,”
and “an end effector comprising a jaw configured to support
a staple cartridge and an anvil rotatable to the jaw between
an open position and a fully-closed position.” ’658 patent
at Abstract. The end effector may comprise first and sec-
ond jaw members, with staples typically deployed from the
staple cartridge in the first jaw member. A driver in the
first jaw member may traverse a channel in the staple car-
tridge and cause the staples to be deformed against the an-
vil located in the second jaw member. “In order to deploy
Case: 20-1600 Document: 44 Page: 3 Filed: 03/15/2021
ETHICON LLC v. INTUITIVE SURGICAL, INC. 3
the staples, the surgical instrument can include . . . a firing
drive for advancing the staple driver within the staple car-
tridge.” Id. at col. 11 ll. 29–32. The stapling system fur-
ther comprises a closure cam operably coupled with the
rotary drive member and configured to transmit a closing
motion to the anvil, and an opening member configured to
apply an opening force to the anvil.
Relevant to this appeal, Figures 3 and 4 of the ’658 pa-
tent provide exploded and partial side views, respectively,
of the handle portion of the surgical stapler:
Case: 20-1600 Document: 44 Page: 4 Filed: 03/15/2021
4 ETHICON LLC v. INTUITIVE SURGICAL, INC.
Id. Figs. 3–4. The surgical instrument of the claimed in-
vention can include handle portion 52, trigger 54, an elon-
gate shaft assembly, and an end effector. In at least one
embodiment, the anvil can be operably connected to trig-
ger 54 such that, upon actuation of trigger 54, the anvil can
be rotated into a closed position. More specifically, trig-
ger 54 can be operably engaged with a closure drive system
configured to translate both the anvil and the channel rel-
ative to the outer sheath of the elongate shaft of the surgi-
cal instrument. As can be seen in Figure 4, “the closure
drive can include cam 68 operably engaged with trigger 54
such that a first actuation of trigger 54 can rotate cam 68
about pin 70 and drive closure links 72 in a substantially
linear direction.” Id. at col. 11 l. 65–col. 12 l. 2. Once the
anvil has been placed in its closed position, “trigger 54 can
be actuated a second time to operate a firing drive which
advances” the cutting member within the end effector. Id.
at col. 13 ll. 3–6. More specifically, “the firing drive can in-
clude trigger gear portion 100 extending from trigger 54,
gear train 102, gear carriage 130, and rotatable drive

shaft 106 which can be configured to advance” the cutting
member within the end effector. Id. at col. 13 ll. 12–17.
Claim 1 is illustrative of the independent claims at is-
sue on appeal. Though dependent claims 4, 9, and 12 each
depends from a different independent claim, they are oth-
erwise substantially the same. Independent claim 1 and
dependent claim 4, which depends from claim 1, recite:
1. A stapling system, comprising:
a housing comprising a rotary drive member;
an elongate shaft extending from said housing,
wherein said elongate shaft defines a longitudinal
axis;
an end effector, comprising:
a jaw configured to support a staple cartridge; and
an anvil rotatable relative to said jaw between an
open position and a fully-closed position, wherein
said anvil comprises a cam surface;
a closure cam operably coupled with said rotary
drive member, wherein said closure cam is config-
ured to move longitudinally to engage said cam sur-
face and transmit a closing motion to said anvil to
move said anvil into said fully-closed position; and
an opening member configured to move longitudi-
nally to apply an opening force to said anvil at a
location other than said cam surface to move said
anvil into said open position.
***
4. The stapling system of claim 1, further compris-
ing a rotary motion generator configured to rotate
said rotary drive member.
Id. at col. 92 l. 54–col. 93 l. 4, col. 93 ll. 9–11 (emphases
added to disputed limitations).
Case: 20-1600 Document: 44 Page: 6 Filed: 03/15/2021
6 ETHICON LLC v. INTUITIVE SURGICAL, INC.
The parties agreed that the terms “rotary drive mem-
ber,” “rotary member,” and “rotatable drive member” (col-
lectively, “the rotary drive terms” or “rotary drive”) should
receive the same construction. They also agreed that the
claimed rotary drive is a component that rotates to drive
another component. The primary claim construction dis-
pute between the parties was whether a component of a
trigger is excluded from the scope of the rotary drive terms.
On appeal, Ethicon alternatively frames the dispute as
whether “the component used to actuate the stapling sys-
tem and the claimed rotary drive [can] be the same compo-
nent.” Appellant’s Reply 6.
In its final written decision, the Board “d[id] not dis-
cern any substantive or meaningful difference in the con-
struction of the ‘rotary drive member’ limitations proposed
by the parties.” Intuitive Surgical, Inc. v. Ethicon, LLC,
IPR2018-00936, slip op. at 10 (P.T.A.B. Jan. 13, 2020) (De-
cision). In its institution decision, however, the Board
noted that, unlike Intuitive’s proposed construction, Ethi-
con’s proposed construction excluded “a ‘trigger’ or any
components associated with a trigger” from the scope of the
rotary drive terms. J.A. 484.
In the institution decision, the Board indicated that it
was “not persuaded that the Specification of the ’658 patent
somehow categorically excludes any component regarded
as, or associated with, a ‘trigger’ from operating as a ‘rotary
drive member.’” Id. The Board concluded that the specifi-
cation’s failure to describe a “trigger” as a “rotary drive
member” was not dispositive of whether a “rotary drive
member” could include a “trigger.” Id. The Board also con-
cluded that the specification’s disclosure of “embodiments
in which both a ‘drive’ component and a ‘trigger’ component
are present in a given device provides little, if any, mean-
ingful insight into” whether a trigger should be excluded
from the scope of the rotary drive terms. Id.
Case: 20-1600 Document: 44 Page: 7 Filed: 03/15/2021
ETHICON LLC v. INTUITIVE SURGICAL, INC. 7
Accordingly, the Board construed the rotary drive
terms to mean “a component that rotates to drive another
component,” which “does not exclude a component re-
garded as a gear or a trigger.” Decision, slip op. at 10.
Applying this construction, the Board held claims 1−14
of the ’685 patent anticipated by Wales. 1 Specifically, the
Board found that gear segment 76 of Wales “is understood
readily and reasonably as a ‘rotary drive member,’” because
“gear segment 76, in pivoting/rotating to effect movement
of yoke 86 to cause distal motion of closure sleeve 32, is
viewed reasonably as a component that rotates to drive an-
other component in response to actuation of the stapling
system.” Id. at 19. These components can be seen in Intu-
itive’s annotation of Figure 7 of Wales (replicated below),
which “depicts a perspective, exploded view of the handle
portion of the proximal end of the surgical instrument,”
Wales col. 3 ll. 61–63:
1 Wales is U.S. Patent No. 6,981,628, filed on July 9,
2003, and titled “Surgical Instrument with a Lateral-Mov-
ing Articulation Control.”
Case: 20-1600 Document: 44 Page: 8 Filed: 03/15/2021
8 ETHICON LLC v. INTUITIVE SURGICAL, INC.
J.A. 353.
Having found claims 1–14 anticipated by Wales, the
Board then addressed Ethicon’s contingent motion to
amend, which requested that the Board substitute pro-
posed claims 15–28 should any of claims 1–14 be found un-
patentable. Intuitive opposed Ethicon’s motion, arguing
multiple grounds for invalidity of each of Ethicon’s pro-
posed substitute claims, including that each claim is inva-
lid as anticipated by Shelton I 2 under 35 U.S.C. § 102(e). 3
The Board agreed with Intuitive and held Ethicon’s pro-
posed substitute claims anticipated under § 102(e) by Shel-
ton I. In view of this finding, the Board did not reach the
merits of Intuitive’s alternative grounds for invalidity of
Ethicon’s proposed substitute claims.
Ethicon appeals the Board’s anticipation finding and
its denial of Ethicon’s contingent motion to amend. We
have jurisdiction pursuant to 28 U.S.C. § 1295(a)(4)(A).
DISCUSSION
On appeal, Ethicon argues that claims 1–14 are not an-
ticipated by Wales under the correct claim construction for
the rotary drive terms, and that the Board erred in denying
Ethicon’s contingent motion to amend with respect to pro-
posed substitute claims 20 and 21. We address each argu-
ment in turn.

posed substitute claims were invalid as: (1) anticipated un-
der 35 U.S.C. § 102(e) by Shelton II (U.S. Patent App. Pub.
No. 2007/0175961); (2) obvious under 35 U.S.C. § 103 over
Wales; (3) obvious under § 103 over Wales and Chang
(U.S. Patent No. 5,295,614); and (4) obvious under § 103
over Wales and Viola (U.S. Patent No. 5,954,259).

I
Ethicon asserts that the Board adopted an unreasona-
bly broad construction for the rotary drive terms. We dis-
agree.
Claim construction is ultimately a question of law that
can involve underlying factual inquiries. Teva Pharms.
USA, Inc. v. Sandoz, Inc., 574 U.S. 318, 333 (2015). We
review the Board’s claim construction based solely on in-
trinsic evidence de novo, while we review subsidiary fac-
tual findings regarding extrinsic evidence, if any, for
substantial evidence. Personalized Media Commc’ns, LLC
v. Apple Inc., 952 F.3d 1336, 1339 (Fed. Cir. 2020). The
broadest reasonable interpretation standard applies to this
inter partes review proceeding. 4
On appeal, Ethicon agrees with the Board that the ro-
tary drive is “a component that rotates to drive another
component.” Appellant’s Br. 38. Ethicon argues, however,
that the proper construction of the rotary drive terms
should be further narrowed to exclude a trigger and a

petition before November 13, 2018, we apply the broadest
reasonable interpretation standard.

component integral with a trigger. We see no basis in the
intrinsic record for limiting the terms in this manner.
Starting with the claim language, the rather generic
terms “rotary drive member,” “rotary member,” and “rotat-
able drive member” do not on their face exclude a trigger
or a component integral with a trigger. For example, in
describing the recited “rotary drive member,” claim 1
simply requires that the rotary drive member be in “a hous-
ing” and “operably coupled with” a closure cam. Nothing
in this language of claim 1 would indicate to an ordinarily
skilled artisan that a “rotary drive member” cannot be a
trigger or part of a trigger. Likewise, though claim 4 re-
quires a “rotary motion generator configured to rotate said
rotary drive member,” nothing in this claim language ex-
cludes the rotary drive member from being integral with
the rotary motion generator, or requires that the rotary
drive member be separate from the rotary motion genera-
tor. The claim language simply requires that the rotary
motion generator be operable to rotate the rotary drive
member.
Turning to the specification, we similarly discern no in-
tent by the inventors to exclude a trigger or component of
a trigger from the scope of the claimed rotary drive terms.
Ethicon asserts that “the specification contains ‘repeated
and consistent descriptions’ of embodiments further de-
scribing the rotary drive as separate and distinct from the
trigger.” Appellant’s Br. 40 (quoting In re Smith Int’l, Inc.,
871 F.3d 1375, 1383 (Fed. Cir. 2017)). Referring to Fig-
ures 1–20 of the ’658 patent, Ethicon also maintains that
“the rotary drive is rotated by trigger 54, which is depicted
and described as a separate component from the rotary
drive.” Id. (citing ’658 patent col. 11 ll. 35–37). We do not
disagree with Ethicon’s description of these figures. As we
have repeatedly held, however, the fact that every embodi-
ment in the specification depicts a particular arrangement
or structure does not necessarily support reading that ar-
rangement or structure into the claims absent express

claim language requiring as much. See Aventis Pharma
S.A. v. Hospira, Inc., 675 F.3d 1324, 1330 (Fed. Cir. 2012)
(“‘[I]t is . . . not enough that the only embodiments, or all of
the embodiments, contain a particular limitation’ to limit a
claim term beyond its ordinary meaning.” (second altera-
tion in original) (quoting Teleflex, Inc. v. Ficosa N. Am.
Corp., 299 F.3d 1313, 1325 (Fed. Cir. 2002))); Innova/Pure
Water, Inc. v. Safari Water Filtration Sys., Inc., 381 F.3d
1111, 1117 (Fed. Cir. 2004) (“[P]articular embodiments ap-
pearing in the written description will not be used to limit
claim language that has broader effect.” (first citing Electro
Sci. Indus., Inc. v. Dynamic Details, Inc., 307 F.3d 1343,
1349 (Fed. Cir. 2002); and then citing Laitram Corp.
v. NEC Corp., 163 F.3d 1342, 1347–48 (Fed. Cir. 1998)));
Liebel-Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 906
(Fed. Cir. 2004) (“[T]his court has expressly rejected the
contention that if a patent describes only a single embodi-
ment, the claims of the patent must be construed as being
limited to that embodiment.” (collecting cases)). This is es-
pecially true here, where Ethicon’s proposed construction
includes a negative limitation.
We have identified claim constructions that exclude a
particular element as including a “negative limitation” and
held that such exclusions must find support either in “the
words of the claim” or through an “express disclaimer or
independent lexicography in the written description that
would justify adding that negative limitation.” Omega
Eng’g, Inc. v. Raytek Corp., 334 F.3d 1314, 1323 (Fed. Cir.
2003) (citing CCS Fitness, Inc. v. Brunswick Corp.,
288 F.3d 1359, 1366–67 (Fed. Cir. 2002)); see also Vehicle
IP, LLC v. AT & T Mobility, LLC, 594 F. App’x 636, 642
(Fed. Cir. 2014) (“Neither the district court nor Appellees
point to any express disclaimer or independent lexicogra-
phy in the intrinsic record that justifies including the neg-
ative limitation ‘not remaining travel time’ in the proper
construction of ‘expected time of arrival.’” (citing Omega,
Case: 20-1600 Document: 44 Page: 12 Filed: 03/15/2021
12 ETHICON LLC v. INTUITIVE SURGICAL, INC.
334 F.3d at 1323)). None of these bases for importing a
negative limitation into the claim language is present here.
Our review of the claim language and specification re-
veals no intent to confer on the claim language the meaning
imparted by Ethicon’s proffered negative limitation. Ac-
cordingly, we conclude that there is no basis in the intrinsic
evidence for importing Ethicon’s negative limitation and
we adopt the Board’s construction.
Ethicon’s argument that the Board erred in finding
claims 1–14 anticipated by Wales is contingent on our
adoption of its proposed claim construction of the rotary
drive terms. Because we adopt the Board’s construction of
the rotary drive terms, we affirm the Board’s finding that
Wales anticipates claims 1–14.
II
Ethicon also appeals the Board’s denial of its contin-
gent motion to amend to add proposed substitute claims 20
and 21, arguing that the Board erred in concluding that
Shelton I is prior art to these claims under § 102(e). We
agree.
Before the Board, Intuitive argued that Ethicon’s con-
tingent motion to amend should be denied because all of
Ethicon’s proposed substitute claims were invalid under
§ 102(e) over Shelton I. Shelton I is titled “Motor-Driven
Surgical Cutting and Fastening Instrument with Adaptive
User Feedback” and lists Frederick E Shelton IV, John N.
Ouwerkerk, and Jerome R. Morgan as inventors.
J.A. 2676. Frederick E. Shelton IV is the sole named in-
ventor of the ’658 patent. Ethicon asserted that Shelton I
is not prior art to the proposed substitute claims because
Mr. Shelton was the sole inventor responsible for concep-
tion of the portions of Shelton I that Intuitive relied on to
anticipate Ethicon’s proposed substitute claims.
J.A. 818−19. Therefore, Ethicon maintained, Shelton I
Case: 20-1600 Document: 44 Page: 13 Filed: 03/15/2021
ETHICON LLC v. INTUITIVE SURGICAL, INC. 13
was not prior art because it was not invented “by another”
for purposes of 35 U.S.C. § 102(e).
The Board agreed with Intuitive and held Ethicon’s
substitute claims anticipated under § 102(e) over Shelton I.
Decision, slip op. at 37–38. In resolving whether
Mr. Ouwerkerk and Mr. Morgan were joint inventors of the
relevant portions of Shelton I, the Board considered decla-
ration testimony from Mr. Shelton and Mr. Morgan in the
framework set out by Duncan Parking Technologies, Inc.
v. IPS Group Inc., 914 F.3d 1347 (Fed. Cir. 2019). Under
Duncan, to be a joint inventor, one must:
(1) contribute in some significant manner to the
conception or reduction to practice of the invention,
(2) make a contribution to the claimed invention
that is not insignificant in quality, when that con-
tribution is measured against the dimension of the
full invention, and (3) do more than merely explain
to the real inventors well-known concepts and/or
the current state of the art.
Id. at 1357–58 (quoting In re VerHoef, 888 F.3d 1362, 1366
(Fed. Cir. 2018)). Duncan further instructs that:
to decide whether a reference patent is “by an-
other” for the purposes of 35 U.S.C. § 102(e), the
Board must (1) determine what portions of the ref-
erence patent were relied on as prior art to antici-
pate the claim limitations at issue, (2) evaluate the
degree to which those portions were conceived “by
another,” and (3) decide whether that other per-
son’s contribution is significant enough, when
measured against the full anticipating disclosure,
to render him a joint inventor of the applied por-
tions of the reference patent.
Id. at 1358.
On appeal, Ethicon asserts that, with respect to pro-
posed substitute claims 20 and 21, the Board erred in
Case: 20-1600 Document: 44 Page: 14 Filed: 03/15/2021
14 ETHICON LLC v. INTUITIVE SURGICAL, INC.
applying the first element of the Duncan test—determin-
ing what portions of the reference patent Intuitive relied
on as prior art to anticipate the claim limitations at issue.
We agree. It is clear from the final written decision that
the Board did not correctly identify the portions of Shel-
ton I that Intuitive relied on to anticipate proposed substi-
tute claims 20 and 21.
The Board found that Intuitive “relies directly and ex-
pressly on content appearing, for instance, at para-
graphs 57–66 (Pet. Opp. 17, 20) of Shelton I in proposing
anticipation of the substitute claims, which is the very con-
tent of Shelton I identified specifically by Mr. Shelton him-
self as exemplary content contributed by Morgan and
Ouwerkerk.” Decision, slip op. at 34. This finding is nei-
ther correct nor supported by substantial evidence.
Mr. Shelton’s declaration identifies paragraphs 59–65 of
Shelton I as containing concepts conceived by Mr. Morgan
and Mr. Ouwerkerk. J.A. 3975–76 (Shelton Dec. ¶ 15). In-
tuitive’s response to Ethicon’s contingent motion to amend
did not rely on paragraphs 59–65 of Shelton I as providing
an anticipating disclosure of proposed substitute claims 20
and 21. Rather, Intuitive’s claim chart mapped proposed
substitute claim 20 to Figures 1–7 and paragraphs 46–47,
49, 52, 54, and 57 of Shelton I, and mapped proposed sub-
stitute claim 21 to Figure 3 and paragraphs 52 and 70–72
of Shelton I. J.A. 711–21, 724. Thus, contrary to the
Board’s finding, Mr. Shelton’s declaration does not admit
that Mr. Morgan and Mr. Ouwerkerk contributed to the
disclosures in Shelton I that Intuitive relied on to antici-
pate proposed substitute claims 20 and 21. 5 For at least
5 Because the Board’s discussion of corroboration re-
lies on the same erroneous identification of the relevant
portions of Shelton I, the Board’s corroboration analysis
rises and falls with our analysis of the propriety of the
Board’s application of Duncan.
Case: 20-1600 Document: 44 Page: 15 Filed: 03/15/2021
ETHICON LLC v. INTUITIVE SURGICAL, INC. 15
this reason, we reverse the Board’s finding that Shelton I
constitutes § 102(e) prior art that anticipates proposed sub-
stitute claims 20 and 21.
We are not persuaded by Intuitive’s post-hoc argument
that the Board’s identification of the relevant portions of
Shelton I as paragraphs 57–66 and Figures 7–10 was cor-
rect. See Appellee’s Br. 50–53. Essentially, Intuitive con-
tends that by expressly identifying Figures 1–7 as
anticipatory disclosures, it by implication identified each of
the paragraphs of Shelton I that provides description of
those figures. Id. at 50. As an example, Intuitive argues
that its identification of Figure 6 also implicated para-
graph 60, which was not expressly identified by Intuitive
as an anticipating disclosure for proposed substitute
claims 20 or 21. Id. But Intuitive’s claim chart mapping
the pertinent Shelton I disclosures to proposed substitute
claims 20 and 21 identified particular paragraphs of Shel-
ton I and, with the exception of paragraph 57 and Fig-
ure 7, 6 did not overlap with the Board’s identification of
relevant material in Shelton I. We reject Intuitive’s de-
layed attempt to bootstrap additional material into the an-
ticipating disclosure Intuitive presented to the Board and
reverse the Board’s finding that Shelton I anticipates pro-
posed substitute claims 20 and 21.
CONCLUSION
We have considered the parties’ remaining arguments
and do not find them persuasive. For the foregoing rea-
sons, we affirm the Board’s finding that Wales anticipates
claims 1–14 under the proper construction, reverse the
Board’s finding that proposed substitute claims 20 and 21
6 Mr. Shelton’s declaration did not identify either of
these portions of Shelton I as portions to which
Mr. Ouwerkerk or Mr. Morgan contributed. See
J.A. 3975−76 (Shelton Dec. ¶ 15).

are anticipated by Shelton I, and vacate the Board’s denial
of Ethicon’s contingent motion to amend with respect to

Board to address whether proposed substitute claims 20
and 21 would be invalid based on any of Intuitive’s alter-
native grounds for invalidity such that Ethicon’s motion to
add proposed substitute claims 20 and 21 should be denied.
