IN RE: RIGGS 2
Before MOORE , Chief Judge, STOLL, and CUNNINGHAM ,
Circuit Judges.
STOLL, Circuit Judge.
This case stems from an Examiner’s request for a re-
hearing by the U.S. Patent Trial and Appeal Board to cor-
rect the Board’s determination that a published patent
application did not qualify as prior art under pre-AIA
35 U.S.C. § 102(e)(1). Leahy-Smith America Invents Act
(“AIA”), Pub. L. No. 112-29, 125 Stat. 284 (2011). The
Board granted the request and determined that the Exam-
iner was correct—the reference did qualify as prior art.
Appellants are the named inventors listed on the pa-
tent application at issue: U.S. Patent Application
No. 11/005,678. They appeal the Board decision affirming
the Examiner’s rejection of the ’678 application. The Ex-
aminer rejected claims 1, 2, 8, 10–13, and 24–25 under pre-
AIA 35 U.S.C. § 102(e) as anticipated by Lettich1 and re-
jected claims 3, 5–7, 9, 15–20, and 22 under 35 U.S.C. § 103
as obvious over Lettich in view of Rojek.2 After determin-
ing that Lettich qualified as prior art under pre-AIA
§ 102(e)(1), the Board sustained the Examiner’s anticipa-
tion and obviousness rejections. Because the Board con-
ducted an incomplete analysis in determining whether
Lettich qualifies as prior art under § 102(e), we vacate and
remand.

IN RE: RIGGS 3
B ACKGROUND
I
The ’678 application is directed to logistics systems and
methods for the transportation of goods from various ship-
pers by various carriers across different modes of transport
(e.g., by rail, truck, ship, or air). The logistics system con-
nects and shares customer order information from various
shippers and information about multiple carriers to pro-
vide “good visibility and management of shipments for all
the parties involved.” J.A. 50 ¶ 25.
The system includes databases, which store data about
shippers and carriers, and component modules. The mod-
ules may use the information in the databases to allow the
system to manage the transportation of goods, for example,
by awarding contracts and producing reports. The specifi-
cation further states that the modules are “scalable to al-
low functionality modules and/or software modules to be
incrementally added as resources . . . permit” or as the
numbers of shippers, carriers, or modes of transportation
change. J.A. 53 ¶¶ 30–31.
Claim 1 is representative for the anticipation rejection
and claim 3 is representative for the obviousness rejection
at issue in this appeal. Claim 1 recites:
1. An integrated logistics system for managing the
shipments of goods by at least one of a plurality of
carriers, said system comprising:
at least one computer;
at least one database, said at least one database
storing data in conjunction with at least two of a
plurality of modules;
a network connecting said at least one computer
and said at least one database; and
Case: 22-1945 Document: 77 Page: 3 Filed: 03/24/2025

-- 3 of 16 --

IN RE: RIGGS 4
at least one storage device, said at least one storage
device storing at least one software program, said
at least one software program when executed by
said at least one computer causing said integrated
logistics system to operate in conjunction with said
plurality of system modules,
said plurality of modules including:
a purchasing module evaluating proposals for re-
spective shipments of goods and awarding con-
tracts for the shipments [to] said one or more
carriers;
a contract administration module maintaining in-
formation relating to the status of proposals re-
ceived and contracts awarded by the purchasing
module;
a scheduling module scheduling shipments accord-
ing to the awarded contracts;
a shipment management module tracking the sta-
tus of shipments awarded by the purchasing mod-
ule and scheduled by said scheduling module; and
a financial module authorizing payments according
to the status of shipments tracked by the shipment
management module,
wherein said information relating to the status of
proposals received and contracts awarded by the
purchasing module is made available to said sched-
uling module, said shipment management module,
and said financial module utilizing said at least one
computer, said at least one database or said net-
work.
J.A. 978–79 (emphases added). Claim 3, which depends
from claim 1 via claim 2, recites:

IN RE: RIGGS 5
3. An integrated logistics system according to
claim 2, wherein said at least one database com-
prises a partitioned relational database storing col-
laborative data relating to shippers, freight
forwarders and ship owners.
J.A. 979.
Lettich is the only prior art reference relevant to our
decision. Lettich is a printed publication of a U.S. non-pro-
visional patent application that claims priority to provi-
sional application No. 60/200,035 filed on April 27, 2000
(the “Lettich Provisional Application”). Lettich describes a
network system that integrates shipping and logistics ser-
vices, operations, and products provided by multiple enti-
ties into a “one stop” site on the internet provided by a
single entity to facilitate logistics operations, such as the
shipping, transporting, warehousing, and distribution of
products for users of the site.
II
This is not our first case involving the ’678 application.
After several procedural disputes over the examination of
the ’678 application, including multiple appeals to this
court, see In re Riggs, 457 F. App’x 923 (Fed. Cir. 2011) (ap-
peal dismissed for lack of jurisdiction); Odyssey Logistics &
Tech. Corp. v. Kappos, 435 F. App’x 954 (Fed. Cir. 2011)
(appeal voluntarily dismissed), the Board heard Appel-
lants’ appeal of the Examiner’s rejections in the ’678 appli-
cation and reversed these rejections in an April 2016
decision. In that decision, however, the Board applied an
incorrect version of 35 U.S.C. § 102(e) to determine
whether Lettich qualified as prior art. The Examiner rec-
ognized the Board’s error and, in September 2016, filed a
Request for Rehearing before the Board. Thereafter, Ap-
pellants filed a complaint in the U.S. District Court for the
Eastern District of Virginia challenging, inter alia, the Re-
quest for Rehearing. See Odyssey Logistics & Tech. Corp.
v. Iancu, 959 F.3d 1104, 1106–07 (Fed. Cir. 2020),
Case: 22-1945 Document: 77 Page: 5 Filed: 03/24/2025

IN RE: RIGGS 6
abrogated on other grounds by Corner Post, Inc. v. Bd. of
Governors of Fed. Rsrv. Sys., 144 S. Ct. 2440 (2024). The
district court dismissed Appellants’ challenge, and we af-
firmed. Id.
The Board issued its Decision on Request for Rehearing
in April 2021. In its Rehearing Decision, the Board stated
that it had jurisdiction over the Request under 35 U.S.C.
§ 6(b). The Board found that the Examiner’s arguments
regarding Lettich’s status as prior art under § 102(e)
“[we]re well taken” and amended its original decision “to
determine that Lettich is proper prior art against the in-
stant claims.” J.A. 12. The Board then reviewed and af-
firmed the Examiner’s anticipation rejection of
representative claim 1 and obviousness rejection of repre-
sentative claim 3 based on Lettich’s disclosure.
Appellants appealed the Board’s decision but, during
the pendency of that appeal, we granted the U.S. Patent
and Trademark Office’s (“USPTO” or “PTO”) motion to va-
cate and remand to allow the Board to address additional
arguments regarding our decisions in Dynamic Drinkware,
LLC v. National Graphics, Inc., 800 F.3d 1375 (Fed. Cir.
2015), and Amgen Inc. v. Sanofi, 872 F.3d 1367 (Fed. Cir.
2017). On remand, the Board adopted its findings and rea-
soning in its Rehearing Decision, reviewed Appellants’ ar-
guments, and held that, because the Lettich Provisional
Application provides adequate support for claim 1 of Let-
tich, Lettich is prior art under § 102(e) against the claims
of the ’678 application.
Appellants timely appealed. We have jurisdiction un-
der 28 U.S.C. § 1295(a)(4).
DISCUSSION
Appellants raise three discrete issues on appeal. First,
to the extent Appellants are not estopped, whether the
Board’s decision to grant the Examiner’s request for re-
hearing was ultra vires. Second, whether the Board
Case: 22-1945 Document: 77 Page: 6 Filed: 03/24/2025

-- 6 of 16 --

IN RE: RIGGS 7
properly afforded Lettich the earlier filing date of its provi-
sional application for purposes of determining that it was
prior art under pre-AIA § 102(e). And third, whether sub-
stantial evidence supports the Board’s findings as to antic-
ipation and motivation to combine. We address the first
two issues and do not reach the third.
I
Collateral estoppel, i.e., issue preclusion, applies when
“(1) a prior action presents an identical issue; (2) the prior
action actually litigated and adjudged that issue; (3) the
judgment in that prior action necessarily required determi-
nation of the identical issue; and (4) the prior action fea-
tured full representation of the estopped party.” VirnetX
Inc. v. Apple Inc., 909 F.3d 1375, 1377 (Fed. Cir. 2018)
(quoting Stephen Slesinger, Inc. v. Disney Enters., Inc.,
702 F.3d 640, 644 (Fed. Cir. 2012)). Here, we agree with
the Government that Appellants are estopped from argu-
ing that the Board acted ultra vires by our prior decision,
Odyssey Logistics, 959 F.3d 1104. Each of the four ele-
ments above supports the application of issue preclusion
and Appellants advance no persuasive reason why they
should not be estopped. We address the four elements out
of order—starting with the fourth element before proceed-
ing to the first, second, and third elements.
As for the fourth element, full representation, Odyssey
Logistics & Technology Corp., the Appellant in Odyssey Lo-
gistics, is the real party in interest here. In the Certificate
of Interest for the present appeal, Appellants state that Od-
yssey Logistics & Technology Corp. is the real party in in-
terest. Certificate of Interest for Appellants, ECF No. 24;
Appellants’ Br. Certificate of Interest (“The full name of
the real party in interest: Odyssey Logistics & Technology
Corporation.”). Thus, we are satisfied that Odyssey’s inter-
ests were fully represented.
Turning to the first and second elements, an identical
issue actually litigated and adjudged, Appellants
Case: 22-1945 Document: 77 Page: 7 Filed: 03/24/2025

-- 7 of 16 --

IN RE: RIGGS 8
previously presented and litigated the same argument—
that the Board lacked jurisdiction to decide the Examiner’s
request for rehearing—before the Board, the district court,
and our court. See Odyssey Logistics, 959 F.3d at 1108–10.
The precise issue before this court in Odyssey Logistics was
whether Odyssey satisfied the Administrative Procedure
Act’s finality requirement, see 5 U.S.C. § 704, for judicial
review of its challenge to the Examiner’s request for re-
hearing. Odyssey Logistics, 959 F.3d at 1108. As part of
its challenge, Odyssey argued that “the rehearing proceed-
ings are an ultra vires action by the PTO.” Id. at 1109.
This court disagreed. Id. at 1109–10. On the merits, our
court concluded that an examiner’s request for rehearing
of a Board decision as outlined in Manual of Patent Exam-
ining Procedure (“MPEP”) § 1214.04 “is ordinary agency
action,” not “an ultra vires action by the PTO” after the
Board’s original decision. Odyssey Logistics, 959 F.3d
at 1109. Indeed, the court determined that “the Board may
reconsider its decision when the examiner requests rehear-
ing.” Id. In reaching this conclusion, the court addressed
the same arguments that Appellants advance here.
First, as Odyssey argued before us in Odyssey Logis-
tics, Appellants here still argue that “the rehearing pro-
ceedings are an ultra vires action by the PTO,” id., because
“the Examiner does not have the right to unilaterally in-
voke, or more accurately, re-invoke the Board’s jurisdiction
over an ex parte appeal after it has ended.” Appellants’
Br. 29. In Odyssey Logistics, we rejected this argument
and explained that the rehearing process is “ordinary
agency action” because “[i]ssuing a request for rehearing
under MPEP [§] 1214.04,” as the Examiner did here,
“simply makes use of the Director’s authority over the ex-
amination process under 35 U.S.C. §§ 131, 132.” Odyssey
Logistics, 959 F.3d at 1110. Second, Odyssey previously
argued, and Appellants continue to argue here, that the
procedure to request a rehearing under MPEP § 1214.04
“cannot apply because the [E]xaminer’s request for
Case: 22-1945 Document: 77 Page: 8 Filed: 03/24/2025

-- 8 of 16 --

IN RE: RIGGS 9
rehearing did not occur within 63 days, and, according to
[Appellants], the Board loses jurisdiction 63 days after it
issues its final decision, and these regulations must super-
sede PTO procedural guidelines from the MPEP.” Id.
at 1109–10 (citing Odyssey’s Reply Br. (which in turn cited
37 C.F.R. §§ 41.52, 41.35(b)(2))); see Appellants’ Br. 28–29.
But none of the cited regulations “constrict the [USPTO’s]
time to request rehearing; they instead bind the patent ap-
plicant.” Odyssey Logistics, 959 F.3d at 1110 (emphasis
added). Appellants also attempt to argue that the
USPTO’s reading of its regulations should not be afforded
deference under Auer v. Robbins, 519 U.S. 452 (1997), or
Kisor v. Willkie, 588 U.S. 558 (2019), because the regula-
tions are not genuinely ambiguous. Appellants’ Br. 29–34.
This argument, like Appellants’ other arguments, misses
the mark. In Odyssey Logistics, we made determinations
regarding the Board’s jurisdiction based on the plain and
unambiguous language of the relevant regulations. Odys-
sey Logistics, 959 F.3d at 1109–10. Last, as they did in the
prior appeal, Appellants assert “they will be quite preju-
diced if they should succeed in this appeal but a patent is
nevertheless not promptly issued,” Appellants’ Br. 36, im-
plying that they will have lost valuable patent term due to
the Board’s action. But this assertion overlooks the fact
that any delay due to appeals at the PTO will result in an
adjusted term based on the patent term adjustment stat-
ute. See 35 U.S.C. § 154(b). Therefore, any concern of prej-
udice is unfounded.
Appellants’ primary response to issue preclusion is
that the pertinent analysis in Odyssey Logistics is dicta be-
cause the main issue there concerned the finality of the
agency’s action, not whether the Board had jurisdiction to
decide the Examiner’s request for rehearing. We are not
persuaded. Questions regarding the propriety of the
Board’s actions and whether those actions were final are
intertwined and required resolution. Indeed, as part of its
finality challenge in Odyssey Logistics, Odyssey argued
Case: 22-1945 Document: 77 Page: 9 Filed: 03/24/2025

-- 9 of 16 --

IN RE: RIGGS 10
that the rehearing proceedings were an ultra vires action
by the PTO. If the court in Odyssey Logistics had concluded
that Board’s actions were ultra vires, the question of final-
ity would be moot. And the district court could grant ap-
propriate equitable relief. See, e.g., Leedom v. Kyne,
358 U.S. 184, 188–89 (1958). Conversely, had we con-
cluded in Odyssey Logistics that the Board’s actions were
not ultra vires (as we did), the Board’s decision to proceed
with the rehearing request resolved the looming question
as to whether the Board’s actions were final (they would
not be final) because “[t]he reconsideration process is the
last stop on the PTO’s path to a final disposition.” Odyssey
Logistics, 959 F.3d at 1109.
As for the third element of issue preclusion, whether
judgment in the prior action necessarily required determi-
nation of an identical issue, as we explained above, our
prior determination that the Board had jurisdiction over
the Examiner’s request for rehearing was “necessarily re-
quired” to resolve whether the Board’s actions were final
under the Administrative Procedure Act. VirnetX,
909 F.3d at 1377. Issue preclusion therefore applies, and
Appellants are estopped from arguing that the Board acted
ultra vires.
II
We now address the Board’s determination that Let-
tich qualifies as prior art under pre-AIA 35 U.S.C. § 102(e).
Lettich is a published non-provisional application that
was filed on April 26, 2001, and claims priority to a provi-
sional application filed on April 27, 2000. The ’678 appli-
cation was filed on December 7, 2004, and claims priority
to July 28, 2000. There is no dispute that Lettich is a pub-
lished non-provisional application that properly claims pri-
ority to the Lettich Provisional Application. Thus, whether
Lettich qualifies as prior art under pre-AIA § 102(e) turns
on whether Lettich is entitled to the priority date of the
provisional application.
Case: 22-1945 Document: 77 Page: 10 Filed: 03/24/2025

-- 10 of 16 --

IN RE: RIGGS 11
Here, the Examiner and the Board relied on Dynamic
Drinkware, Amgen, and MPEP § 2136.033 to conclude that
“at least one claim in the Lettich Application Publication
must find written description support in the Lettich Provi-
sional Application in order for the Lettich Application Pub-
lication to be prior art against the instant claims.” J.A. 35;
see also J.A. 34 (citing Dynamic Drinkware, 800 F.3d
at 1382; Amgen, 872 F.3d at 1380). Applying this test, the
Board identified corresponding support in the Lettich Pro-
visional Application for each limitation of Lettich non-pro-
visional application published claim 1. See J.A. 35–38.4
3 MPEP § 2136.03 provides:
The critical reference date under pre-AIA 35 U.S.C.
102(e) of a U.S. patent, a U.S. patent application
publication, as well as an international application
publication having prior art effect under pre-AIA
35 U.S.C. 102(e), may be the filing date of a relied
upon provisional application only if at least one of
the claims in the reference patent, patent applica-
tion publication, or international application publi-
cation is supported by the written description of the
provisional application in compliance with pre-AIA
35 U.S.C. 112, first paragraph, or 35 U.S.C. 112(a).
MPEP § 2136.03 III (9th ed., Rev. 01.2024, Nov. 2024) (ci-
tations omitted). Additionally, the MPEP requires that
“[t]he provisional application must also describe, in compli-
ance with pre-AIA 35 U.S.C. 112, first paragraph, or
35 U.S.C. 112(a), the subject matter relied upon in the ref-
erence patent or publication to make the rejection.” Id.
4 We requested supplemental briefing to address
whether the law applied by the Board—requiring at least
one of the claims in the reference patent application publi-
cation be supported by the written description of the
Case: 22-1945 Document: 77 Page: 11 Filed: 03/24/2025

-- 11 of 16 --

IN RE: RIGGS 12
While we have explained that a prior art patent or pub-
lished application cannot be accorded the benefit of its pro-
visional application’s filing date absent a showing that the
provisional application provides support for the claims of
the patent or published application, Dynamic Drinkware,
800 F.3d at 1381–82; Amgen, 872 F.3d at 1380, we have not
addressed the scenario at issue here. Specifically, we have
not addressed whether the Board’s test is sufficient where,
as here, the Examiner (or any party challenging the valid-
ity of a patent) demonstrated support for one claim and
then relied on other portions of the specification (e.g., the
Summary of the Invention or Detailed Description, or even
other claims) to support its rejection. We conclude it is not.
Even if one demonstrates that a provisional application
provides written description support for one claim of the
non-provisional application or patent, the provisional ap-
plication must also provide written description support for
the specific portions of the patent specification identified
and relied on in the prior art rejection. In other words, to
claim priority to the provisional filing date, the portion of
the application relied on by the examiner as prior art must
be supported by the provisional application. It makes no
sense to suggest that if a single claim is supported by the
provisional application, then everything in the later filed
application gets the benefit of the provisional date whether
supported or not. As explained below, this additional re-
quirement is both logical and consistent with our
provisional application in compliance with pre-AIA
35 U.S.C. § 112, first paragraph—was correct. ECF No. 67
at 2. We asked the parties to “consider whether it is appro-
priate to require that ‘at least one claim,’ all claims, or only
the subject matter (e.g., a paragraph in the specification)
relied on to reject the claims at issue have support in the
provisional application in order to qualify as prior art as of
the provisional priority date.” Id.
Case: 22-1945 Document: 77 Page: 12 Filed: 03/24/2025

IN RE: RIGGS 13
precedent. Additionally, it is consistent with MPEP
§ 2136.03 (see supra note 3).
Provisional applications become public when the corre-
sponding non-provisional application publishes or the pa-
tent issues. See 37 C.F.R. § 1.14(a)(1)(iv)–(vi); Appellee’s
Suppl. Br. 8. As such, it is best to treat a published provi-
sional application—like a published non-provisional appli-
cation or patent—as prior art for all that it teaches as of its
filing date.
In both Dynamic Drinkware and Amgen, the appellants
failed to demonstrate that the respective provisional appli-
cations provided written description support for the patent
claims. Dynamic Drinkware, 800 F.3d at 1381–82 (“No-
where, however, does [appellant] demonstrate support in
the Raymond provisional application for the claims of the
Raymond patent. That was [appellant]’s burden. A provi-
sional application’s effectiveness as prior art depends on its
written description support for the claims of the issued pa-
tent of which it was a provisional. [Appellant] did not make
that showing.” (emphasis added)); Amgen, 872 F.3d
at 1380 (“Here, [a]ppellants challenged the district court’s
application of Dynamic Drinkware, but did not proffer any
evidence showing that the provisional applications . . . sat-
isfy the written description requirement for the [subject
matter] claimed in the [reference application].”). As such,
we did not address the subsequent issue of whether the
content of the prior art relied on in the rejection also re-
quired written description support in the provisional appli-
cation.
Here, it appears the Board interpreted Dynamic Drink-
ware and Amgen to mean that if a single claim in the prior
art published non-provisional application is adequately
supported by the written description of the provisional ap-
plication, then the filing date of the provisional applies
carte blanche to the prior art published application, irre-
spective of whether the cited content in the prior art
Case: 22-1945 Document: 77 Page: 13 Filed: 03/24/2025

-- 13 of 16 --

IN RE: RIGGS 14
published application was adequately supported by the
written description of the provisional application. We dis-
agree with this approach. A reference constitutes prior art
for all that it teaches as of its earliest accorded filing date.
A reference does not constitute prior art for all that it
teaches as of its provisional application’s filing date solely
because a particular claimed invention—which most often
does not specify everything in the written description—is
adequately supported by the provisional application.
In its supplemental brief, the USPTO asserts that the
Board in this case “determine[d] that the disclosure of the
Lettich Provisional Application provides proper support for
claim 1 of the Lettich Application Publication, as well as
for the subject matter in the Lettich Application Publication
relied on in the rejection.” Appellee’s Suppl. Br. 4 (empha-
sis added) (citing J.A. 29–30, 33–38). We agree that the
Board found support in the Lettich Provisional Application
for each limitation of Lettich non-provisional application
claim 1, see J.A. 35–38, and we conclude that substantial
evidence supports these findings. But we disagree that the
Board addressed whether the disclosure of the Lettich Pro-
visional Application provides support for the subject mat-
ter in Lettich that the Examiner relied on in the rejection.
The Board noted that the Examiner determined which por-
tions of Lettich were supported by the Lettich Provisional
Application, but the Board did not review the Examiner’s
findings in this regard. J.A. 29–30. Because the Board did
not, in the first instance, complete this analysis as to
whether Lettich qualifies as prior art under pre-AIA
35 U.S.C. § 102(e), we vacate and remand for the Board to
determine whether the Lettich Provisional Application
provides written description support for the specific disclo-
sures in Lettich that the Examiner identified and relied on
in the prior art rejections.
We are not persuaded by Appellants other arguments
for why Lettich is allegedly not entitled to the priority date
of the provisional application. First, Appellants assert that
Case: 22-1945 Document: 77 Page: 14 Filed: 03/24/2025

-- 14 of 16 --

IN RE: RIGGS 15
“[t]he system of Lettich claim 1 is described in para-
graphs 30–34 and enabled at paragraphs 165–175 of the
Lettich non-provisional application[,]” but “[t]hese para-
graphs of the Lettich non-provisional application do not ap-
pear in the provisional application and there are no other
parts of the provisional application that fully describe and
enable claim 1.” Appellants’ Br. 20–21. Appellants ex-
plain, “[t]here is not even any effort in the Dynamic Drink-
ware [discussion in] the [Board] Decision on Remand to
show that claim 1 of the Lettich non-provisional applica-
tion is enabled by the provisional application.” Id. at 21.
Contrary to Appellants’ assertion, the Board does provide
analysis on whether the provisional application is ena-
bling. See J.A. 32–33. Appellants’ problem before the
Board, and here, is that they present only attorney argu-
ment and “d[id] not provide any factual evidence to support
its arguments that Lettich’s provisional application is non-
enabling.” J.A. 33. Attorney argument “is not evidence
and cannot rebut other admitted evidence.” Elbit Sys. of
Am., LLC v. Thales Visionix, Inc., 881 F.3d 1354, 1359
(Fed. Cir. 2018) (internal quotation marks and citation
omitted). And a party’s position that is based on attorney
argument rather than record evidence does not undermine
substantial evidence that supports the Board’s findings.
See Facebook, Inc. v. Windy City Innovations, LLC,
973 F.3d 1321, 1342 (Fed. Cir. 2020).
We are also not persuaded by Appellants’ argument
that the Intellectual Property and High Technology Tech-
nical Amendments Act of 2002 (“TAA”), Pub. L. 107–273,
116 Stat. 1758, does not apply retroactively to the ’678 ap-
plication. The Examiner and the Board correctly recog-
nized that pre-AIA § 102(e), as revised by the TAA, applies
to all patents and applications pending on, or filed after,
November 29, 2000—i.e., it applies to all existing applica-
tions. This is clear from the effective date language in the
TAA itself, which states that the amendments shall apply
“to any pending application filed before November 29,

2000.” Pub. L. 107–273, 116 Stat. at 1903. Here, because
the ’678 application was pending at the time the TAA went
into effect, the plain language of the TAA controls.
C ONCLUSION
We have considered Appellants’ remaining arguments
and do not find them persuasive. For the reasons above,
we vacate the Board’s decision as to whether Lettich qual-
ifies as prior art under 35 U.S.C. § 102(e) and remand for
proceedings consistent with this opinion.
VACATED AND REMANDED
C OSTS
No costs.
