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.  The ITC has therefore decided to continue to exclude products it found to be infringing certain patents, regardless of the PTAB invalidating the very patents the exclusion order is based upon in separate IPR proceedings.  While this decision aiding patentees may surprise some, it is consistent with the ITC’s practices regarding stays and of giving little deference to IPR proceedings.

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.”

In 2001, Oil States Energy Services LLC (“Oil States”) was granted U.S. Patent No. 6,179,053 for a lockdown mechanism to ensure a mandrel is locked in an operative position during fracking.  Oil States sued Greene’s Energy Group LLC (“Greene’s Energy”) in the Eastern District of Texas in 2012 for infringing this patent, and in turn, Greene’s Energy petitioned the United States Patent and Trademark Office (USPTO) to institute an IPR on the patent.  This petition was granted. After the proceedings, the Patent Trial and Appeal Board (PTAB), the administrative body of the USPTO that handles IPRs, concluded the challenged patent claims were invalid.  Oil States appealed to the Federal Circuit, which affirmed the decision, and Oil States then petitioned the Supreme Court for certiorari.

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.  The PTAB found the ’577 and ’668 Patents invalid but upheld the validity of the ’853 Patent.  The Inter Partes Review (“IPR”) proceedings were brought by Arista Networks in retaliation to Cisco’s accusations of infringement brought in multiple venues, including at the U.S. International Trade Commission (“ITC”), which had just a few weeks earlier upheld the validity of these very same patents and determined that Arista infringed the ’577 and ’668 Patents, and issued exclusion and cease and desist orders accordingly.  Since the IPR decisions issued Arista has filed a petition asking the ITC to suspend its limited exclusion order regarding the ’577 Patent based on the PTAB’s decision and is expected to file a similar request with respect to the ’668 Patent.  On the other side, Cisco plans to appeal the PTAB’s decisions to the Federal Circuit.  The uncertainty created by these inconsistent outcomes is an issue for patent owners, and it will be interesting to see how these cases are resolved.  In addition, this case shows that even though the ITC does not stay its investigations for IPRs, IPRs may still impact ITC proceedings.

723px-US-CourtOfAppeals-FederalCircuit-Seal_svgIn its opinion in Aylus Networks, Inc. v. Apple Inc., the Federal Circuit expanded the scope of prosecution disclaimer to statements made by a patent owner during Inter Partes Review (IPR) proceedings.  The Court explained that extending the doctrine to cover patent owner statements, made either before or after institution of an IPR, ensures that claims are not argued in one way to maintain patentability and a different way to support infringement allegations.  The Court also noted that its conclusion promotes the public notice function of intrinsic evidence and protects the public’s reliance on statements made during IPR proceedings.

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.”

Synopsys sued ATopTech in 2013 for allegedly infringing the ‘967 patent. ATopTech subsequently filed two inter partes review (IPR) petitions (IPR2014-01150 and IPR2014-01159) challenging the validity of all claims of the ‘967 patent. The ‘967 patent aims to improve circuit performance by splitting large components into small subcomponents and optimizing the connections between subcomponents. Claim 1 requires “flattening each of said plurality of hierarchically arranged branches by eliminating superfluous levels of hierarchy above said atomic blocks.”  Claim 32 requires “determining optimal placement of each of the hard blocks, if any, within the predefined area.”  The Board found both claims either obviousness or anticipated in view of the Fields and/or Su references.

USPTO SealOn April 7, 2017, the U.S. Patent and Trademark Office (USPTO) announced it has launched an initiative to develop ways to improve Patent Trial and Appeal Board (PTAB) proceedings, particularly inter partes review proceedings.  The effort includes analyzing five years’ worth of historical data covering PTAB proceedings and user experiences.  The USPTO hopes to use this data analysis to ensure the proceedings are as “effective and fair as possible within the USPTO’s congressional mandate to provide administrative review of patentability of patent claims after they issue.”

When the Patent Trial and Appeal Board issues a final written decision finding against an IPR Petitioner, can that Petitioner necessarily appeal that adverse decision?  In a case of first impression, the Federal Circuit recently answered “no.”

In Phigenix, Inc. v. ImmunoGen, Inc., the Federal Circuit held that Petitioner Phigenix lacked standing to appeal the PTAB’s final IPR decision in favor of Patent Owner ImmunoGen because Phigenix failed to prove that there was an actual “case or controversy” between it and ImmunoGen concerning the challenged patent.  According to the Federal Circuit, although such a “case or controversy” may not be necessary for Phigenix to appear in an IPR proceeding before an administrative agency like PTAB, it remains a requirement for Phigenix to seek appellate review in a federal court.

The Federal Circuit reversed the invalidation of two patents directed to providing security for credit card purchases in an opinion released earlier today.  The patents at issue, U.S. Patent Nos. 7,840,486 and 8,036,988, disclose methods for effecting secure credit-card purchases by minimizing merchant access to credit card numbers.  Both patents were the subject of inter partes reviews launched by a subsidiary of MasterCard Inc. after patent owner John D’Agostino sued for infringement of the claims of both patents in Delaware federal court in April of 2013.
