Inter Partes Review

PTABWatch Takeaway: Sovereign immunity is not available to dismiss an IPR challenge where the Patent Owner has filed an infringement action against the Petitioner. Ericsson v. Regents of the University of Minnesota, IPR2017-01186, -01197, -01200, -01213, -01214, and -01219 (Dec. 19, 2017).

The Eleventh Amendment was rarely mentioned in the same breath as patent law until last year, which began with the Board’s decision in Covidien LP v. University of Florida Research Foundation Inc., IPR2016-01274, -01275, -01276 (Jan. 25, 2017), discussed here. In Covidien, the Board dismissed petitions for IPR challenging the claims of a patent owned by the University of Florida Research Foundation, determining that the university is an arm of the state and entitled to invoke sovereign immunity to bar IPR institution. Sovereign immunity does not shield against any and all challenges, however. In Reactive Surfaces Ltd., LLP v. Toyota Motor Corp., Case No. IPR2017-00572 (July 13, 2017), discussed here, the Board acknowledged that sovereign immunity may be asserted by a state university in an IPR, but held that an IPR may continue against a non-sovereign co-owner of the challenged patent.

Update: The Supreme Court issued a decision on April 20, 2020  holding that the patent statute (35 U.S.C. § 314(d)) bars judicial review of a PTAB decision of whether an inter partes review petition is time-barred pursuant to 35 USC 315(b). As stated by the Court, the PTAB’s “application of §315(b)’s time limit, we hold, is closely related to its decision whether to institute inter partes review and is therefore rendered nonappealable by§314(d).”

**********

Original Post: In Wi-Fi One, LLC v. Broadcom Corporation, an en banc panel of the Federal Circuit decided on January 8, 2018, that the PTAB’s application of the 35 U.S.C § 315(b) time bar to institution of inter partes review (IPR) proceedings is reviewable on appeal. The decision overrules Achates Reference Publishing, Inc. v. Apple Inc., 803 F.3d 652 (Fed. Cir. 2015), which held to the contrary.

Update: On June 10, 2019, the Supreme Court issued a decision, 6-3, reversing the Federal Circuit’s judgment and remanding the case for further proceedings. The Court held that “a federal agency is not a ‘person’ who may petition for post-issuance review under the AIA.” On August 9, 2019, the Federal Circuit issued an order vacating the PTAB’s decision and remanding with instructions that the PTAB dismiss the CBM proceeding for lack of jurisdiction.

PTABWatch Takeaway: When “sued for infringement” within the meaning of 28 U.S.C. § 1498(a), the United States has standing to petition the Patent Office to institute Covered Business Method (CBM) review.  Return Mail v. U.S. Postal Service, Appeal 2016-1502 (Fed. Cir. Aug. 28, 2017)

Background

Patentee, Return Mail, Inc., filed suit in the U.S. Court of Federal Claims Court alleging that the United States, through the actions of the United States Postal Service, used without license the subject matter claimed in U.S. Pat. No. 6,826,548.

Last fall, the Federal Circuit reversed a PTAB decision that affirmed an Examiner’s rejection of various claims in an ex parte reexamination because the Examiner’s interpretation of the claims, which the PTAB upheld, was unreasonably broad. In re Smith International, Inc., Appeal No. 2016-2303 (Fed. Cir. Sept. 26, 2017). The court’s decision is noteworthy because it reinforces the bounds of the broadest reasonable interpretation claim construction standard the Patent Office must apply when assessing patentability, bounds that do not encompass the broadest possible interpretation.

In CRFD Research Ltd. v. Matal, No. 2016-2198 (Fed. Cir. Dec. 5, 2017), the Federal Circuit determined that the PTAB erred in its obviousness analysis, in part by failing to consider an argument the IPR petitioner made in a ground that the PTAB determined was “redundant” to the instituted grounds.

Petitioner Hulu, LLC, challenged claims of CRFD Research Ltd.’s patent directed to methods of transferring an ongoing software-based session from one device to another, allowing the user to begin a session on one device, such as a cell phone, and then transferring the session to another device, such as a laptop computer.

In Ultratec, Inc. v. CaptionCall, LLC, No. 2016-1706 (Fed. Cir. Aug. 28, 2017), the Federal Circuit vacated and remanded multiple IPR decisions where the PTAB failed to consider material evidence and failed to explain its decisions to exclude the evidence.

Ultratec and CaptionCall are currently litigating in both district court and before the PTAB.  Ultratec sued CaptionCall for infringement in the Western District of Wisconsin where a jury found the patents infringed and not invalid.

The PTAB’s Chief Administrative Patent Judge issued a memorandum on November 21, 2017, providing guidance on motions to amend in view of the en banc decision of the Federal Circuit in Aqua Products, Inc. v. Matal, 872 F.3d 1290 (Fed. Cir. 2017) (discussed here and here).  The court in Aqua Products determined that the Board could not the place burden of persuasion with respect to the patentability of substitute claims on the patent owner.  The memorandum stated that the Board will determine whether substitute claims submitted in a motion to amend compliant with 35 U.S.C. § 316(d) are unpatentable by a preponderance of the evidence based on the entirety of the record, including any opposition made by the petitioner.

The Federal Circuit’s decision in Eli Lilly & Co. v. Teva Parenteral Medicines, Inc., 845 F.3d 1357 (Fed. Cir. 2017) attracted much attention for applying the theory of divided infringement in the context of pharmaceutical therapeutic regimen claims.  Before the Federal Circuit decision, a scrum of petitioners successfully petitioned for IPR of the Lilly patent, alleging that the claims were obvious in view of a combination of references that included prior art considered by the court in the litigation. Our previous post highlighted the potential for inconsistent results that AIA trials may present relative to district court actions concerning the same patent.

Two recent Federal Circuit decisions illustrate how an error in construing claims may lead the court to reverse a PTAB final written decision. In Organik Kimya AS v. Rohm & Haas Co., the Federal Circuit determined that the PTAB correctly construed the disputed claim term, “swelling agent,” and therefore affirmed the PTAB’s decisions upholding the patentability of challenged claims directed to processes for preparing emulsion polymers. In contrast, in Owens Corning v. Fast Felt Corp., decided on the same day, the court determined that the PTAB erred in construing the term “roofing or building cover material” too narrowly, and thus reversed the PTAB’s decision canceling claims directed to methods of applying polymer “nail tabs” on roofing and building cover material.
