attacks on the patentability of the same
patent claims and the harassment of
patent owners.
The case-specific analysis the Office
has developed attempt to balance
Congress’s intent for AIA proceedings to
be ‘‘quick and cost effective alternatives
to litigation,’’ on the one hand, with
‘‘the importance of quiet title to patent
owners to ensure continued investment
resources,’’ on the other hand. H.R. Rep.
No. 112–98, pt. 1, at 48 (2011). For
example, the Office has set forth, in
various precedential PTAB decisions,
various factors used in its case-specific
analysis. See, e.g., General Plastic Co.,
Ltd. v. Canon Kabushiki Kaisha,
IPR2016–01357, 2017 WL 3917706, at
*7 (PTAB Sept. 6, 2017) (precedential)
(providing a nonexclusive list of factors
that the Board considers when
evaluating discretionary denial of
follow-on petitions, also known as
‘‘serial’’ petitions, under 35 U.S.C.
314(a)); Valve Corp. v. Elec. Scripting
Prods., Inc., IPR2019–00062, –00063,
–00084, 2019 WL 1490575 (PTAB Apr.
2, 2019) (precedential) (Valve I)
(explaining that the Board considers any
relationship between petitioners when
weighing the General Plastic factors);
Valve Corp. v. Elec. Scripting Prods.,
Inc., IPR2019–00064, –00065, –00085,
2019 WL 1965688 (PTAB May 1, 2019)
(Valve II) (applying the first General
Plastic factor to a petitioner that joined
a previously instituted IPR proceeding
and, therefore, is considered to have
previously filed a petition directed to
the same claims of the same patent);
Apple Inc. v. Fintiv, Inc., IPR2020–
00019, 2020 WL 2126495 (PTAB Mar.
20, 2020) (precedential) (summarizing
the factors the Office has considered
when a patent owner argues for
discretionary denial under NHK Spring
Co., Ltd. v. Intri-Plex Techs., Inc.,
IPR2018–00752, 2018 WL 4373643
(PTAB Sept. 12, 2018) (precedential)
due to an earlier trial date).
These same considerations are also
represented in various informative
decisions. See, e.g., Sand Revolution II,
LLC v. Continental Intermodal Group-
Trucking LLC, 2020 WL 3273334 (PTAB
June 16, 2020) (informative) (applying
the factors set forth in the precedential
Fintiv decision to grant institution);
Apple Inc. v. Fintiv, Inc., IPR2020–
00019, 2020 WL 2486683 (PTAB May
13, 2020) (informative) (applying the
factors set forth in the precedential
Fintiv decision to deny institution);
Adaptics Ltd. v. Perfect Co., IPR2018–
01596, 2019 WL 1084284 (PTAB Mar. 6,
2019) (informative) (applying discretion
to deny a petition where the petition
lacks particularity in identifying the
asserted challenges that resulted in
voluminous and excessive grounds);
Deeper, UAB v. Vexilar, Inc., IPR2018–
01310, 2019 WL 328753 (PTAB Jan. 24,
2019) (informative) (applying discretion
to deny a petition where the petitioner
demonstrates a reasonable likelihood of
prevailing only as to 2 claims out of 23
claims challenged and only as to 1 of 4
asserted grounds of unpatentability);
Chevron Oronite Co. v. Infineum USA
L.P., IPR2018–00923, 2018 WL 5862245
(PTAB Nov. 7, 2018) (informative)
(applying discretion to deny a petition
where the petitioner demonstrates a
reasonable likelihood of prevailing only
as to 2 claims out of 20 claims
challenged).
As the Office explained in the
Consolidated Trial Practice Guide,
consideration of this case-specific
analysis is ‘‘part of a balanced
assessment of all relevant circumstances
in the case, including the merits.’’ CTPG
at 58 (discussing consideration of the
merits as part of a balanced assessment
of the General Plastic factors); see also
Fintiv, 2020 WL 2126495, at *2–3, 6–7
(discussing consideration of the merits
in the context of discretionary denial).
Informed by similar considerations,
the Office has also provided guidance
on the number of petitions typically
required by a petitioner to challenge the
same patent at or about the same time.
See CTPG 59–61 (first introduced in
Trial Practice Guide Update (July 2019)
at 26–28, available at https://
www.uspto.gov/TrialPracticeGuide3
(requiring petitioners to rank multiple
petitions filed at the same time that seek
to challenge the same patent)). The
Board explained that, based on its prior
experience, ‘‘one petition should be
sufficient to challenge the claims of a
patent in most situations.’’ Id. at 59. In
some cases, depending on
circumstances, ‘‘two petitions by a
petitioner may be needed, although this
should be rare.’’ Id. The Board,
however, concluded that it is ‘‘unlikely
that circumstances will arise where
three or more petitions by a petitioner
with respect to a particular patent will
be appropriate.’’ Id.
The Office is now considering
promulgating rules based on the
framework of the guidance provided in
these decisions and in the Consolidated
Trial Practice Guide, or a modified
framework as appropriate, based on
public input and further analysis. These
considerations form the impetus for this
request for comments and the questions
presented below.
Discretion Under 35 U.S.C. 314(a) and
324(a)
Addressing Serial Petitions
In
General Plastic, the Board
recognized the goals of the AIA and also
‘‘recognize[d] the potential for abuse of
the review process by repeated attacks
on patents.’’ 2017 WL 3917706, at *7
(citing H.R. Rep. No. 112–98, pt. 1, at 48
(2011)). To aid the Board’s assessment
of ‘‘the potential impacts on both the
efficiency of the IPR process and the
fundamental fairness of the process for
all parties,’’ General Plastic enumerated
a number of nonexclusive factors that
the Board will consider in a case-
specific analysis for exercising
discretion on instituting an IPR,
especially as to ‘‘follow-on’’ or ‘‘serial’’
petitions challenging the same patent as
challenged previously in an IPR, PGR,
or CBM proceeding. Id. at *8. The
General Plastic nonexclusive factors
include: (1) Whether the same petitioner
previously filed a petition directed to
the same claims of the same patent; (2)
whether, at the time of filing of the first
petition, the petitioner knew of the prior
art asserted in the second petition or
should have known of it; (3) whether, at
the time of filing of the second petition,
the petitioner had already received a
patent owner’s preliminary response to
the first petition or received the Board’s
decision on whether to institute review
in the first petition; (4) the length of
time that elapsed between the time the
petitioner learned of the prior art
asserted in the second petition and the
filing of the second petition; (5) whether
the petitioner provides an adequate
explanation for the time elapsed
between the filings of multiple petitions
directed to the same claims of the same
patent; (6) the finite resources of the
Board; and (7) the requirement under 35
U.S.C. 316(a)(11) to issue a final
determination not later than one year
after the date on which the Director
notices institution of review. Id. at *7.
Since General Plastic, the Office has
explained that the application of the
first General Plastic factor is not limited
to instances where multiple petitions
are filed by the same petitioner. For
instance, in Valve I, the Board denied
institution when a party filed follow-on
petitions for IPR after the denial of an
earlier IPR request of the same claims
filed by the party’s co-defendant. Valve
I, 2019 WL 1490575, at *4–5. The Board
held that when different petitioners
challenge the same patent, the Board
considers the relationship, if any,
between those petitioners when
weighing the General Plastic factors. Id.
The Office also explained, in Valve II,
that the first General Plastic factor
