The STRONGER (Support Technology & Research for Our Nation’s Growth and Economic Resilience) Patents Act of 2017 was recently introduced in the Senate.  The Act is an updated version of the STRONG Patents Act of 2015 that stalled in Congress.  Like its predecessor, the STRONGER Patents Act is designed to significantly modify the AIA trial proceedings at the PTAB.  Enactment of this Act would severely diminish the usefulness of AIA proceedings.

In Google Inc. v. Intellectual Ventures II LLC, Appeal 2016-1543, 2016-1545 (Fed. Cir. July 10, 2017), the Federal Circuit affirmed the PTAB’s final written decision canceling some claims of U.S. Patent No. 6,121,960, but vacated the portion of the decision that refused to cancel other claims.  With respect to the upheld claims, the court remanded the matter because the PTAB failed to adequately explain its findings, noting that the PTAB’s “disagreement with [the petitioner] … does not amount to a satisfactory explanation for its finding” that those claims are not unpatentable.  Google at 12.

In three recent decisions, the Federal Circuit reiterated the importance of determining estoppel in PTAB proceedings on a claim-by-claim basis.

In the earlier related decisions, In re Affinity Labs of Texas, LLC [1] , 856 F.3d 883 (Fed. Cir. 2017) and In re Affinity Labs of Texas, LLC [2], 856 F.3d 902 (Fed. Cir. 2017), the court addressed the effects of a district court judgment and settlement of a district court litigation on pending pre-AIA reexamination proceedings.

Third parties seeking to challenge pre-AIA patents in the USPTO often choose between IPR and ex parte reexamination.  In some cases, petitioners pursue both proceedings, sequentially or in parallel, taking advantage of different timelines to completion, different standards for institution, and using insights gained in one proceeding in the other.  The PTAB recently exercised its discretion to terminate three reexaminations filed against patents also challenged by IPR in Ariosa Diagnostics, Inc. v. Illumina, Inc., IPR2014-01093, Paper 81 (May 24, 2016).  In the pending appeal, the stage is set for the Federal Circuit to consider the extent of the PTAB’s discretion in terminating post-grant proceedings in these circumstances.  Case Nos. 2016-2388, 2017-1020 (Fed. Cir.).

Merging concept illustrated by two different jigsaw piece a silver and a gold one.

Teva Pharmaceuticals USA, Inc. (“Teva”) filed a Petition, seeking an IPR of claims 1–20 of Allergan’s U.S. Patent No. 8,642,556. [IPR2017-00579, Paper No. 9]  Along with the Petition, Teva filed a Motion for Joinder to join Mylan Pharmaceuticals Inc. v. Allergan, Inc., IPR2016-01129.  This blog has previously reported on the topic of joinder in IPR Petitions here and here.

Teva’s Petition was not timely, having been filed more than one year after Allergan filed a complaint alleging infringement of the ‘556 patent against Teva.  Teva’s Motion for Joinder, however, was filed within one month of the date that the Board instituted review in response to Mylan’s Petition.  Under 37 C.F.R. § 42.122(b), Teva’s Motion for Joinder with Mylan’s Petition was timely.

An updated discussion of this issue is available here: The Supreme Court Finds IPR Proceedings Constitutional

The Supreme Court issued an order on June 12, 2017, indicating it will review the Federal Circuit’s judgment in Oil States Energy Services, LLC v. Green’s Energy Group, LLC, 639 Fed. Appx. 639 (Fed. Cir. 2016) (link).  The petition presented three questions, of which the Court will address only one:

Whether inter partes review—an adversarial process used by the Patent and Trademark Office (PTO) to analyze the validity of existing patents—violates the Constitution by extinguishing private property rights through a non-Article III forum without a jury.

In the latest development in the ongoing patent battle between Google and SimpleAir Inc., a Federal Circuit panel agreed with SimpleAir that Google waived a claim construction it asserted on appeal because Google had failed to argue that construction before the PTAB.

SimpleAir originally asserted a series of patents against Google, including U.S. Patent No. 8,601,154 (“the ’154 patent”) directed to a data communication system connecting on-line networks with on-line and off-line computers. Google challenged the validity of the ’154 patent in an IPR.  The PTAB determined the challenged claims of the ’154 patent were not invalid, concluding that Google failed to identify in the prior art “a central broadcast server,” recited in the challenged claims.  Google appealed the PTAB’s final written decision, and argued that the PTAB erred in its interpretation of this limitation.

In a recent final written decision (Trustees of the University of Pennsylvania v. Coalition for Affordable Drugs VIII, LLC, IPR2015-01835, Paper No. 56 (PTAB Mar. 6, 2017)), the Board determined that the Coalition for Affordable Drugs (“Petitioner”) failed to demonstrate that claims 1-10 of U.S. Patent No. 8,618,135 (“the ’135 patent) were obvious. The claims recite methods of treating a subject suffering from a disorder associated with hyperlipidemia and/or hypercholesterolemia. Petitioner asserted these claims were obvious because the alleged prior art taught applying step-wise escalating doses of a microsomal triglyceride transfer protein (MTP) inhibitor to treat hyperlipidemia and hypercholesterolemia. As in cases we have previously discussed here and here, the Petitioner failed to satisfy its burden of proof because it did not show that the alleged prior art qualified as a “printed publication.”

IPRs are an attractive option for biosimilar applicants to clear the patent landscape before delving into litigation under the Biologics Price Competition and Innovation Act of 2009 (BPCIA), which is still in its infancy.  Roche’s Herceptin® (trastuzumab) is a prime target for biosimilar makers, accounting for sales of over $6.5 billion in 2015.  Mylan, Celltrion, and Pfizer, all with competing biosimilar candidates, have filed IPR petitions challenging patents reportedly covering trastuzumab.  Recently, the PTAB granted a petition filed by Hospira (subsidiary of Pfizer) to institute IPR of U.S. Patent No 7,807,799 (“the ’799 patent”), directed to protein A affinity chromatography.  Hospira, Inc. v. Genentech, Inc., IPR2016-01837, Paper No. 19 (April 7, 2017).

In IPR 2016-00039, Costco challenged claims 1, 12 and 14 of USPN 7,228,588 owned by Bosch and drawn to beam (non-yoked) windshield wipers with spoilers to keep the wipers in contact with the windshield in high winds.  Petitioner combined one reference with each of two other references in support of obviousness challenges to the claims. In defense of the claims, Patent Owner relied on evidence in the challenged patent and on expert testimony.  The Board found PO’s evidence contradicted by other evidence of record and found PO’s expert testimony related to challenged patents not at issue in this IPR.  Further, the Board found that evidence of secondary considerations of non-obviousness was insufficiently developed and held the challenged claims unpatentably obvious.
