In Meiresonne v. Google, Inc., No. 2016-1755 (Fed. Cir. Mar. 7, 2017), the Federal Circuit affirmed the PTAB’s final written decision in IPR2014-01188 that the challenged claims in U.S. Patent No. 8,156,096 (the “’096 patent”) are unpatentable as obvious over the 1997 book “World Wide Web Searching for Dummies, 2nd Edition” by Brad Hill (“Hill”) and U.S. Patent No. 6,271,840 (“Finseth”). The sole issue before the Federal Circuit was whether Hill and Finseth teach away from the claimed invention.

The ’096 patent teaches a directory website that contains (1) a plurality of links to supplier websites, (2) “a supplier descriptive portion” located near a corresponding supplier link, (3) “a descriptive title portion” describing the class of goods or services listed on the website, and (4) “a rollover view area” that displays information about at least one of the suppliers corresponding to a link.

Apple Icon ImagesA little more than a month after the Delaware district court narrowly interpreted the IPR estoppel provision to suggest that it may not be necessary to include all known grounds so as to avoid estoppel in district court litigation, the same court issued a decision suggesting that the IPR estoppel provision may not be so narrow after all.  The decision adds to the growing confusion over the scope of the estoppel provision Congress wrote into the AIA.

On December 20, 2013, Parallel Networks Licensing, LLC (“Parallel Networks”) sued International Business Machines Corporation (“IBM”) in the Delaware district court for infringement of U.S. Patent Nos. 5,894,554 (“the ‘554 Patent”) and 6,415,335 (“the ‘335 Patent”).  Parallel Networks Licensing, LLC v. International Bus. Machs. Corp., Case No. 13-2072 (D. Del.).  IBM answered and counterclaimed seeking declaratory judgments of non-infringement and invalidity based on anticipation and obviousness.

A recent set of final written decisions in four IPRs against Acorda Therapeutics puts more marks in the loss column for Kyle Bass and the Coalition for Affordable Drugs.  In IPRs 2015-01850, -01853, -01857 and -01858 (Coalition for Affordable Drugs v. Acorda Therepuatics Inc.), the Coalition for Affordable Drugs (CFAD) requested review of Acorda Therapeutics U.S. patents U.S. 8,440,703, U.S. 8,007,826, U.S. 8,663,865, and U.S. 8,354,437, respectively, directed to sustained release formulations of fampridine (4-AP) and methods for administering the drug to treat neurological disease, such as multiple sclerosis (MS).  Certain aspects of the inventions in the four patents are directed to methods of increasing walking speed of patients with MS by administering 4-AP twice daily for at least two weeks, in a dose of about 10 to 15 mg of 4-AP.  The PTAB instituted review of the issued claims in each of the four patents as potentially obvious in view of a combination of prior art, including an SEC filing by Acorda that included reference to ongoing clinical trials.

IPR 2015-01651 involved a dispute over the obviousness of claims in U.S. Patent No. 8,551,271 owned by Crown Packaging Technology, Inc. and drawn to a grooved crown bottle cap with thinner, harder steel than used in conventional caps.  World Bottling Cap, LLC, petitioned the Board to cancel the ’271 patent claims as being obvious based on two lines of attack.  The Board held the evidence of obviousness to be insufficient, with evidence of secondary considerations of non-obviousness contributing to the Board’s decision that no claims of the ’271 patent were unpatentable.

In the spirit of “if at first you don’t succeed, try, try again,” the Coalition for Affordable Drugs (CFAD) challenged a fourth Orange Book-listed patent relating to VIVOMO®, Horizon Pharma’s naproxen/ esomeprazole product.  While denying CFAD’s previous three petitions, the PTAB instituted inter partes review for U.S. Patent No. 8,945,621.  Despite CFAD’s success at the institute phase, the PTAB ultimately determined in its Final Written Decision that the Petitioner did not meet its burden in proving the unpatentability of the challenged claims.

logo-minThe PTAB Bar Association held its first conference in Washington DC March 1-3, 2017 with more than 400 attendees and a wait list of interested individuals. PTAB Chief Judge David Ruschke gave the keynote address.

Chief Judge Ruschke began by acknowledging why we are now at a point where there is an interest in having a PTAB Bar Association. Specifically, he noted that the PTAB has become a vital component of the patent system. We have seen that reflected in an incredible rise in appeals to the Federal Circuit from the PTAB and also that post-grant proceedings are now an important tool for every patent litigator.

In Slot Speaker Techs., Inc. v. Apple Inc., Nos. 2015-2038, 2015-2039 (Fed. Cir. February 17, 2017) (non-prec.), the Federal Circuit affirmed a portion of the PTAB’s decision in an IPR that concluded claims 1 and 2 of U.S. Patent No. 7,433,483 would have been obvious over a combination of two prior art references, but reversed the portion that concluded that the same combination does not render dependent claim 3 obvious. The decision is interesting because the Board and the Federal Circuit concluded that the reduced effectiveness of the combined references as compared to a single reference  alone would not deter a person of skill in the art from having a reasonable expectation of success in making the invention.

In Unwired Planet, LLC v. Google Inc., the Federal Circuit affirmed the PTAB’s IPR decision that the challenged claims are invalid as obvious and dismissed the PTAB’s CBM review as moot.

Petitioner Google filed IPR and CBM petitions challenging claims 1-6 of U.S. Patent No. 7,024,205 (“the  ’205 patent”) owned by Unwired Planet, LLC.  The ’205 patent describes a system and method for providing wireless network subscribers with prioritized search results based on the location of the mobile device.  Claim 1 is the sole independent claim of the ’205 patent and recites “farther-over-nearer ordering” in the context of wireless location-based services.  We previously discussed a related CBM review between the same parties.

In MPHJ Technology Investments, LLC v. Ricoh Americas Corp., Appeal 2016-1243 (Fed. Cir. Feb. 13, 2017), the Federal Circuit affirmed the PTAB’s final written decision canceling all eight claims in U.S. Patent No. 8,488,173. The patent issued from an application that was the tenth continuation-in-part of a 20-year-old application that relies for priority on seven provisional applications. The decision may be noteworthy if only because it highlights how seemingly-minor changes to these applications over time influenced the PTAB’s interpretation of certain claim terms—an interpretation that finally led the PTAB and court to conclude the claims were not patentable, just as the patent is about to expire.

In IPR2015-01157, 10X Genomics, Inc. challenged claims 1-31 of USPN 8,889,083 owned by the University of Chicago.  PTAB instituted trial on grounds of obviousness over two references.  Each party relied on the testimony of one or more experts, and the Patent Owner challenged expert testimony as exceeding the proper scope of Petitioner’s Reply.

The technology at issue involved a device and method for pressurized transport of fluidic plugs, or droplets, in microfluidic systems used in chemical and biochemical reactions.  The plug form of transport arises by injecting fluid containing reagents and a fluorinated surfactant into an immiscible fluorinated carrier fluid flowing in non-fluorinated microchannels of a microfluidic system.
