The Federal Circuit has once again vacated and remanded a PTAB final written decision on the basis that the PTAB did not adequately explain its reasons for finding a claimed invention obvious.  In In re Nuvasive, Appeal No. 15-1670 (Fed. Cir. Dec. 7, 2016), the Federal Circuit reviewed the PTAB’s final written decision in IPR2013-00506 that concluded various claims of  NuVasive, Inc’s U.S. Patent No. 8,361,156 were invalid as obvious over a combination of prior art references.  The patent claims spinal fusion implants, and were challenged by Medtronic Inc.

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).”

On January 19, 2018, the Federal Circuit issued an order vacating the decision discussed in the post below and reinstating the appeal for reconsideration in view of the court’s en banc decision in Wi-Fi One LLC v. Broadcom Corporation, which we discuss here. A new decision on the merits may be expected later in 2018.

Original Post: In Click-to-Call Techs. v. Oracle Corp., Appeal 15-1242 (Fed. Cir. Nov. 17, 2016) (non-prec.), on remand from the Supreme Court for further consideration in view of Cuozzo Speed Technologies, LLC v. Lee, 136 S. Ct. 2131 (2016) (as we discussed here), the Federal Circuit again dismissed the patent owner’s (Click-to-Call’s) appeal, concluding that the court lacks jurisdiction to review a decision by the PTAB to institute an Inter Partes Review (IPR) petition over a patent owner’s objections that the IPR petition is time barred.

Digital Billboard (12-6-16 Post)Galaxia Electronics Co., Ltd. v. Revolution Display, LLC, PGR2016-00021, Galaxia sought post-grant review of Revolution’s U.S. Design Patent No. D736,750, entitled “Modular Video Support Frame Member.” The patented design was directed to a support frame for video monitors used in large-scale LED video image displays, such as those used on-stage at rock concerts, on the sides of buildings, or at amusement parks.  Galaxia sought cancellation of the claimed design on grounds of non-joinder of proper inventors, and lack of ornamentality under 35 U.S.C. § 171.  On November 2, 2016, the PTAB denied institution of the PGR.

To date, only 43 petitions for Post-Grant Review have been filed with the PTAB.  Nine PGR petitions (21% of total petitions) have been filed to challenge patents arising from Art Unit 1600, which examines applications directed to biotechnology and organic chemistry subject matter.  The PTAB recently instituted the third ever PGR for a biotech-related patent in B.R.A.H.M.S. Gmbh v. Becton, Dickinson & Co., PGR2016-00018.

The petitioner requested PGR of claims 1-12 of U.S. Patent No. 9,091,698, directed to a method for the advanced detection of sepsis in a systemic inflammatory response syndrome (SIRS)-positive subject involving measuring procalcitonin levels and one or more clinical markers over multiple time points, wherein an increase in the amount of procalcitonin from a previous amount over a 24-hour interval detects sepsis.

An updated discussion of this issue is available here: Supreme Court Decides that IPR Final Decisions Must Address All Challenged Claims

The Federal Circuit recently denied a petition for rehearing en banc, effectively reiterating that the PTAB may, in its sole discretion, choose to institute an IPR proceeding on some, but not all, of the patent claims challenged in an IPR petition.  The rehearing petition sought the full court’s review of a split three-judge panel decision in SAS Institute, Inc. v. Complementsoft, LLC, Nos. 2015-1346, -1347 (Fed. Cir. Jun. 10, 2016), that applied Synopsys, Inc. v. Mentor Graphics Corp., 814 F.3d 1309 (Fed. Cir. 2016), to conclude that there is no statutory requirement that a PTAB final written decision address every claim raised in an IPR petition.

Writing on the calendar.

A split panel of the Federal Circuit held that the PTAB applied a standard that was too exacting when it required an inventor to prove the “continuous exercise of reasonable diligence” to antedate a prior art reference. Rather, the PTAB should have applied the rule of reason to determine if the inventor proved that there was “reasonably continuous diligence.” Perfect Surgical Techniques v. Olympus America, Inc., Case No. 2015-2043, __ F.3d __ (Fed. Cir. Nov. 15, 2016). This clarified standard appears to ease the burden on a party seeking to prove diligence.

In considering a novel issue of Post-Grant Review (PGR) eligibility, the Patent Trial and Appeal Board followed the straightforward language of the America Invents Act (“AIA”), and longstanding precedent, holding that post-filing amendments to a pre-AIA patent application do not change its effective filing date and, thus, do not make it eligible for PGR.  David O.B.A. Adebimpe v. Doang-Trang T. Vu & The Johns Hopkins Univ., Case PGR2016-00020, Paper No. 14 (P.T.A.B. July 25, 2016).

In two final written decisions (IPR2015-01093 and IPR2015-00990), the PTAB found that challenged claims in Shire’s U.S. Patent No. 7,056,886 (the ’886 patent) were invalid as obvious.  The decisions highlight potential issues related to patents directed to pharmaceutical formulations that petitioners and patent owners alike may want to consider if confronted with an IPR related to such subject matter.

The Coalition for Affordable Drugs filed two petitions for IPR, one challenging claims 1−45 of U.S. Patent No. 7,056,886 (IPR2015-01093) and one challenging claims 46−52 and 61−75 of the ’886 patent (IPR2015-00990).

In Unwired Planet, LLC v. Google Inc., the Federal Circuit vacated the PTAB’s final decision in a CBM review because the PTAB had applied an overly broad standard to determine that the challenged claims were directed to a “financial product or service” subject to CBM review, and remanded the case for evaluation under the proper standard.

Google had filed a petition for CBM review of Unwired’s patent entitled “Method and System for Managing Location Information for Wireless Communications,” and in particular, claims directed to methods of limiting access to location information for wireless communication devices. According to Google, the patent is eligible for CBM review, and it notes that the specification discusses using the claimed methods to facilitate advertising, which would facilitate financial activity.

Neither the Federal Circuit nor the PTAB has provided much guidance concerning the proper application of the one-year time-bar for filing IPRs when privity is alleged.  Recently, however, in AM General LLC v. UUSI, LLC, Case IPR2016-01049, Paper 14 (PTAB November 7, 2016), the PTAB has provided some guidance.

On May 18, 2016, Petitioner AM General LLC filed a Petition requesting inter partes review of various claims of U.S. Patent No. 5,570,666 (“the ‘666 Patent”).  In its Preliminary Response to the Petition, filed on August 19, 2016, the Patent Owner, UUSI, LLC, urged denial of the Petition, contending the petition was time barred.
