IPRs & Other Post Grant Proceedings

Last week the Patent Trial and Appeal Board (“PTAB”) provided yet another arrow in the patent owner’s quiver for defending against institution of IPRs.  In NHK International Corp. v. Intri-Plex Technologies, Inc., IPR2018-00752, the PTAB exercised its discretion under 35 U.S.C. § 325(d) and denied institution because the asserted art was already considered during the original examination of the patent.  The PTAB also found that denial was warranted under 35 U.S.C. § 314(a) in light of the additional factor that a district court trial on the same patent was imminent. 

The U.S. Patent and Trademark Office announced a propose change to the standard for construing both unexpired and amended patent claims in Patent Trial and Appeal Board (PTAB) proceedings under the America Invents Act (“AIA”).

As we noted in our blog post last week, the USPTO held its “Chat with the Chief on SAS” webinar on April 30, 2018, to advise the public on the implications of the Supreme Court’s opinion in SAS Institute for practice before the Board going forward.

When trying to overcome an obviousness rejection of a patent claim, an argument that two or more cited references cannot be combined may be used.  For example, it can be argued that the combination is improper because the modification of a reference completely changes its “fundamental principle of operation.”

In its first en banc decision of 2018, the Federal Circuit held that “judicial review is available for a patent owner to challenge the U.S. Patent and Trademark Office’s determination that the petitioner satisfied the timeliness requirement of 35 U.S.C. § 315(b) governing the filing of petitions for inter partes review.”

On December 19, 2017, an expanded panel of the Patent Trial and Appeal Board (PTAB) ruled that the state of Minnesota waived its Eleventh Amendment immunity to challenges to patent validity by inter partes review (IPR) by filing suit in federal court alleging infringement of the same patent being challenged by IPR. 

On December 19, 2017 the Patent Trial and Appeal Board (the “Board”) held a “Chat with the Chief” webinar in which Chief Judge David Ruschke presented very recent developments on a variety of topics related to practice before the Board, including Aqua Products guidance for motions to amend, new procedures for handling remands, and the expanded panel process.

On November 21st, the PTAB issued guidance on motions to amend based on the Federal Circuit’s en banc decision in Aqua Products, Inc. v. Matal, 872 F.3d 1290 (Fed. Cir. 2017).

In June, we covered the Supreme Court’s grant of certiorari in Oil States Energy Servs., LLC v. Greene's Energy Grp., LLC, 137 S. Ct. 2239 (2017). The Court will decide whether inter partes review – an adversarial process used by the Patent and Trademark Office (PTO) since September 16, 2012 to analyze the validity of existing patents – violates the Constitution by extinguishing private property rights through a non-Article III forum without a jury.

Earlier this week, the United States Patent and Trademark Office (“USPTO”) published a new rule governing when privilege exists for communications between clients and their domestic or foreign patent attorneys and patent agents before the Patent Trial and Appeal Board (“PTAB”).

In a precedential opinion issued on October 11, 2017, the United States Court of Appeals for the Federal Circuit reversed the Patent Trial and Appeals Board’s (“PTAB”) finding of non-obviousness where the prior art taught away from some, but not all, of the embodiments covered by the challenged claims.

On September 6, 2017, an expanded panel of the Patent Trial and Appeal Board issued an “informative” decision in General Plastic Industrial Co., Ltd, v. Canon Kabushiki Kaisha setting forth the Board’s framework for analyzing follow-on inter partes review (IPR) petitions.

The United States Court of Appeals for the Federal Circuit’s recent decision in Aqua Products Inc., v. Matal materially changes the burden of proof associated with the patentability of amended claims during an inter partes review (“IPR”), shifting the burden from the Patent Owner seeking the amendment to the IPR Petitioner opposing it.

On August 25, 2017, the Patent Trial and Appeal Board issued a precedential opinion in Ex Parte McAward, reaffirming the Patent Office’s use of a lower pre-issuance threshold for indefiniteness distinct from the Supreme Court’s Nautilus standard.

In a first of its kind decision with important ramifications for patentees, the U.S. International Trade Commission (“ITC”) denied a petition to suspend or temporarily rescind remedial orders issued in Investigation No. 337-TA-945 pending appeal of the Patent Trial and Appeal Board’s (“PTAB”) separate finding that the patent claims at issue are invalid.

In EmeraChem Holdings LLC v. Volkswagen Group of Am. Inc., the Federal Circuit reminded the PTAB that it must abide by the APA’s requirements of adequate notice and an opportunity to respond when conducting a post-grant review.

In a move that could drastically change the patent law landscape, the United States Supreme Court recently granted certiorari in Oil States Energy Services LLC v. Greene’s Energy Group LLC, No. 16-712, to answer the question whether the inter partes review (IPR) process violates the U.S. Constitution by “extinguishing private property rights through a non-Article III forum without a jury.”

The Patent Trial and Appeal Board (“PTAB”) issued Final Written Decisions regarding Cisco’s U.S. Patent Nos. 6,377,577 (the “’577 Patent”) and 7,023,853 (the “’853 Patent”) on May 25, 2017 and U.S. Patent No. 7,224,668 (the “’668 Patent”) on June 1, 2017.

On May 10, 2017 and following a Patent Trial and Appeal Board (PTAB) reexamination decision upholding certain claims, the United States Court of Appeals for the Federal Circuit ruled in Cisco Systems, Inc. v. Cirrex Systems, LLC that all of the appealed claims of a fiber optic patent held by Cirrex are invalid for lack of a written description support required by 35 U.S.C. § 112.

The Federal Circuit has now reversed the Patent Trial and Appeal Board’s decision in Synopsys, Inc. v. ATopTech, Inc.  finding claims 1 and 32 of U.S. Patent No. 6,567,967 (the “‘967 patent”)  as being “not supported by substantial evidence.”
