Federal
01 ‘” – Federal Circuit
The U.S. Court of Appeals for the Federal Circuit (CAFC) on Wednesday issued a precedential decision reversing a Patent Trial and Appeal Board (PTAB) ruling that found on remand from the CAFC claims of Qualcomm’s patent for integrated circuit devices were unpatentable.
The decision relates to two inter partes review (IPR) petitions brought by Apple, Inc. against Qualcomm’s U.S. Patent No. The Apple Apple also challenged the claims as unpatentable under Section 103 based on two prior patents and one publication, but the Board said that Apple had not proven unpatentability on this ground.
Qualcomm I
In Qualcomm’s first appeal to the CAFC, the court vacated and remanded the decisions, explaining that the Board’s determination that “prior art consisting of patents or printed publications” includes AAPA was incorrect. However, the CAFC remanded the case for the PTAB to decide “whether Apple’s petition nonetheless raises its SS 103 challenge on the basis of prior art consisting of patents or printed publications.”
35 U.S.C. SS 311(b) says that “A petitioner in an inter partes review may request to cancel as unpatentable 1 or more claims of a patent only on a ground that could be raised under section 102 or 103
and only on the basis of prior art consisting of patents or printed publications.”The PTAB originally held: “Because AAPA is admitted to be prior art and is found in the ‘674 patent, it can be used to challenge the claims in an inter partes review.” The Board also said that “prior art consisting of patents or printed publications” includes AAPA because it is prior art contained in a patent. The The court explained:
“We agree with Qualcomm and the PTO that the ‘patents or printed publications’ that form the ‘basis’ of a ground for inter partes review must themselves be prior art to the challenged patent. This This interpretation is consistent with prior judicial interpretations of the statute and represents a more natural reading of SS 311(b).”
Despite that holding, the CAFC likewise noted that AAPA is still not “categorically excluded” from an IPR. Citing Koninklijke Philips N.V. v. Google LLC, 948 F.3d 1330, 1339 (Fed. Cir. Cir Cir. The The The original Guidance agreed with Qualcomm that AAPA does not fall within “prior art consisting of patents or printed publications” under SS 311(b), but read CAFC caselaw to permit the use of AAPA in IPR as evidence of the general knowledge of a skilled artisan.
The updated Guidance was issued in June 2022 and responded to the CAFC’s decision in Qualcomm I by interpreting Section 311(b) “to require an ‘in combination’ rule: In an IPR petition that ‘relies on admissions in combination with reliance on one or more prior art patents or printed publications, those admissions do not form ‘the basis’ of the ground.”
On remand, the PTAB again found the claims unpatentable on Ground 2 and said the AAPA at issue did not form “the basis” of the ground and thus complied with Section 311(b).
Qualcomm II
On appeal for the second time, the CAFC first addressed Apple’s argument, citing Cuozzo Speed Techs., LLC v. Lee, 579 U.S. 261 (2016), that Qualcomm’s appeal is not reviewable because it amounts to a challenge to the Board’s determination to institute the IPRs. Apple But the court said Qualcomm was not challenging the “threshold” decision to institute the IPRs, but instead, “the Board’s determination of unpatentability on Ground 2, with respect to the use of AAPA in reaching that determination.” The opinion added: “In other words, Qualcomm’s challenge pertains to the Board’s interpretation and application of statutory provision, SS 311(b), on what qualifies as a permissible basis for a ground in an IPR petition.”
The CAFC then turned to Qualcomm’s arguments that the Board erred in interpreting SS 311(b) and in determining that Ground 2 complied with SS 311(b).
On the first point, the CAFC held that the Board’s interpretation “contravened the plain meaning of the statute.” The opinion explained that Qualcomm I, “clarified that, according to the plain language of SS 311(b), related case law, and a ‘natural reading’ of the statute, AAPA is not a prior art patent or printed publication. Thus, because the basis can only include prior art consisting of patents or printed publications, and because AAPA is not a prior art patent or printed publication (per Qualcomm I), it follows that the plain meaning of SS 311(b) does not permit the basis to include AAPA.”
However, the PTAB interpreted Section 311(b) to mean that AAPA does “not form ‘the basis’ of the ground” where “an IPR petition relies on admissions in combination with reliance on one or more prior art patents or printed publications.” The CAFC rejected this view, noting that it “would establish an ‘in combination’ rule that would provide that AAPA cannot form the basis of a ground and, as a result, must be considered by the Board, whenever a petition combines AAPA with prior art patents or printed publications.”
Holding that AAPA can never form the basis of a ground under Section 311(b) if it is combined with prior art patents or printed publications “would not account for situations where a petition relies on AAPA in combination with prior art patents and printed publications but also includes the same AAPA as the basis or part of the basis,” wrote the CAFC. The The The The According While “reliance on AAPA in combination with prior art patents or printed publications is not dispositive of whether AAPA is included in the basis of a ground…what is dispositive are express statements–as in Apple’s petitions…” and the court ultimately “agreed with Qualcomm that Apple should be held to the phrasing of its petition because an IPR petitioner is the ‘master of its own petition.'”
The PTAB’s determination of unpatentability was therefore reversed.
