A number of significant changes occurred in 2018 at the U.S. Patent and Trademark Office (USPTO). To begin with, in February 2018, a new USPTO Director took office.  Director Andrew Iancu, a former patent litigator with law firm experience, appears to have brought a different perspective than that of his corporate predecessors – Michel Lee (Google) and David Kappos (IBM) – to the job at the helm of the USPTO.  In his Senate confirmation hearings, Iancu made it clear that he felt that better balance was needed in the administrative review of issued patents by the USPTO under the America Invents Act (AIA).   He pledged to assess “improvements in the AIA trial standards and processes.”  Iancu identified “institution decisions, claim construction, the amendment process, and the conduct of hearings” as areas that warranted study.  In fact, Director Iancu did a lot more than study these aspects of practice before the Patent Trial and Appeal Board (PTAB) in 2018.

In a final rule published in the Federal Register on October 11, 2018, the U.S. Patent and Trademark Office (USPTO) took a remarkable step of acknowledging unfairness in the way its Patent Trial and Appeal Board (PTAB) has been conducting trials for the past six years. The rule change will apply to all of the

The 2011 America Invents Act (AIA) provided a variety of new ways to administratively challenge patents, including the now widely used inter partes review (“IPR”) procedure.  In two recent appeals of IPR decisions, Genentech has challenged the constitutionality of IPR proceedings when applied to patents that were already issued as of the date that the AIA was enacted.

Genentech has filed two appeals to the Court of Appeals for the Federal Circuit (“Federal Circuit”) involving decisions by the U. S. Patent Office’s Patent Trial and Appeal Board (“PTAB”) invalidating certain patent rights issued to Genentech on immunotherapy biologics. (Federal Circuit Docket Nos. 18-1933 and 18-1959.)  These patents have been asserted against a number of competitors seeking to market biosimilar products to Genentech’s Avastin® and Herceptin® antibody therapeutics.

The appeals stem from two IPR Petitions filed by Hospira, IPR2016-01771 and IPR2016-01837, that challenged claims of U.S. Patent Nos. 7,622,115 and 7,807,799, respectively. The ’115 Patent issued in November 2009 and the ’799 Patent issued in October, 2010 – both issuance dates being well before the 2011 enactment of the AIA.  The PTAB initiated trials on both patents and ultimately found all of the challenged claims to be invalid over the prior art presented by Hospira.

Genentech’s briefs assert “the retroactive application of inter partes review to a patent issued before that procedure existed is unconstitutional, a taking without just compensation and a denial of due process,” in violation of the Constitution’s Fifth Amendment.

The Federal Circuit has now certified Genentech’s constitutional challenges to the U.S. Attorney General, who has been directed to inform the Court whether the United States intends to intervene in the appeals within 30 days.

Genentech’s position may seem like a “Hail Mary pass” effort to save its patents, especially in light of the U.S. Supreme Court’s decision earlier this year in Oil States Energy Services, LLC v. Greene’s Energy Group, LLC, No. 16-712, 138 S. Ct. 1365 (2018) (“Oil States”), where the Court rejected the patent owner’s argument that revoking patent claims as a result of an IPR proceeding is unconstitutional under Article III and the Seventh Amendment.

In the Oil States case, the Court held that the decision to grant a patent is a matter involving public rights and, hence, a challenge to a patent’s validity need not be heard exclusively in an Article III federal court and does not require a jury trial.  (For our detailed analysis of the Oil States decision, click here.)

However, Genentech’s arguments are based on the Fifth Amendment’s prohibition on taking private property for public use without just compensation by a process that did not exist when the property rights were granted. The author of the Oil States decision, Justice Clarence Thomas, emphasized the narrowness of the holding in the Oil States case and made it clear that the case addresses “only the precise constitutional challenges . . . raised here.” Oil States at 1369.

The U.S. Supreme Court’s decision this week in SAS Institute v. Iancu has upended a major provision of the U.S. Patent and Trademark Office (PTO) regulations for inter partes and post grant review proceedings conducted by its Patent Trial and Appeal Board (PTAB).  By concluding in a 5-4 decision that the agency lacks the authority

The Patent Trial and Appeal Board (PTAB) has not taken kindly to a move by the Irish drug company Allergan to shield its key patents on its dry-eye drug Restasis from challenge at the U.S. Patent Office by assigning these patents to the Saint Regis Mohawk Tribe in return for a commitment by the tribe,

A few months ago, the Irish drug company Allergan moved to shield its key patents on its dry-eye drug Restasis from challenge at the Patent Trial and Appeal Board (PTAB) of the U.S. Patent Office by assigning these patents to the Saint Regis Mohawk Tribe in return for a commitment by the tribe, as new owner of the patents, to invoke “sovereign immunity” and request that the PTAB dismiss pending administrative challenges.

However, a recent decision in an unrelated case before the PTAB casts doubt on the viability of this strategy.  In Ericsson v. Regents of the University of Minnesota, IPR2017-01186 (Paper 16 PTAB Dec. 19, 2017), an expanded panel of seven PTAB judges denied the University of Minnesota’s motion to dismiss an inter partes review (IPR) proceeding on the basis of sovereign immunity.  According to the PTAB panel, by filing a patent infringement suit that asserted the challenged patent, the University had waived its immunity at least with respect to the defendants.  One of defendants in that suit, Ericsson, Inc., had initiated the IPR proceeding.

The Ericsson decision involved the questionable practice of “panel-packing” by the PTAB’s chief judge, David Ruschke.  In this instance, the Chief Judge added himself and three of his deputies to the original three judges assigned to the case for the purpose of deciding the University’s motion to dismiss, ostensibly to address the “exceptional nature of the issues presented.”

Two prior PTAB decisions by different panels of judges involving University-owned patents have upheld the sovereign immunity principle.  In Covidien LP v. Univ. of Fla. Research Found., Inc., Case IPR2016-01274 (PTAB Jan. 25, 2017) and NeoChord, Inc. v. Univ. of Md., Balt., Case IPR2016-00208 (PTAB May 23, 2017), prior panels of PTAB judges faced with this issue had found that an IPR proceeding was an adjudicatory proceeding of a federal agency from which state entities are immune.

Judge Ruschke’s opinion on behalf of the enlarged panel confirmed that the sovereign immunity defense was generally available to state universities (and, by implication, other sovereigns like native American tribes) but the immunity was not absolute.  By suing in federal court, Ruschke reasoned that University of Minnesota had waivered this immunity.  He distinguished the prior PTAB panel decisions dismissing IPR petitions on sovereign immunity grounds because they did not involve “a State that filed an action in federal court alleging infringement of the same patent.”  (The Covidien v. Florida case arose out of a licensing dispute in which the university had sued to enforce a patent license agreement and the disgruntled licensee then challenged the patent via an IPR petition.  The Neochord v. Maryland case likewise involved a licensing dispute.)

Nonetheless, Judge Ruschke’s opinion has a logical weakness.  The panel’s finding of a waiver appears to turn on the fact that an invalidity challenge to a patent in a federal infringement case is a compulsory counterclaim.  Because the invalidity challenge must be brought or “be forever barred from doing so, it is not unreasonable to view the state as having consented to such counterclaims.”  The opinion fails to explain why the counterclaim inherent in an infringement suit (i.e. a trial of the invalidity issue in the federal court) is not sufficient in and of itself or why the compulsory nature of the counterclaim should spawn a right to raise this issue in an alternative forum with significantly different (challenger-friendly) rules.

On October 4, 2017, the Court of Appeals for the Federal Circuit, sitting en banc, overruled an earlier panel decision and found that the Patent Trial and Appeal Board (PTAB) had been impermissibly placing the burden of proving the patentability of amended claims on the Patent Owner, rather than the Petitioner.   See, Aqua Products

In an unusual move to combat the perceived bias in favor of patent challengers at the U.S. Patent Office’s Patent Trial and Appeal Board (PTAB), the Irish drug company Allergan has decided to warehouse its key patents on the dry-eye drug Restasis with the Saint Regis Mohawk Tribe in upstate New York.  Allergan generates over

The Federal Circuit Court of Appeals again vacated a Patent Trial and Appeal Board (PTAB) panel decision for failing to properly evaluate “objective evidence of non-obviousness” and remanded the case for determinations consistent with its opinion. Specifically, the Fed. Cir. panel faulted the PTAB’s analysis Patent Owner’s objective evidence of unexpected results and further found

In a decision last month, the Court of Appeals for the Federal Circuit gave petitioners in AIA proceedings yet another weapon to invalidate patents – by affirming a Patent Trial and Appeal Board (PTAB) decision that relied, at least in part, on new evidence introduced by the petitioner in its reply brief. (Genzyme Therapeutic Products LP v. BioMarin Pharmaceutical Inc., Fed. Cir. No. 15-1720).

Writing for a three-judge Fed. Cir. panel, Judge William C. Bryson said it should be expected that petitioners will introduce new evidence during the course of an Inter Partes Review (IPR) proceeding. Judge Bryson dismissed the notion that the record of an IPR is essentially closed following the PTAB’s institution decision.

“There is no requirement either in the board’s regulations, in the [Administrative Procedures Act] or as a matter of due process for the institution decision to anticipate and set forth every legal or factual issue that might arise in the course of the trial,” according to Judge Bryson.

Genzyme had argued that it was impermissible for the PTAB to relied on different evidence than the evidence relied upon in the institution decision.

“Genzyme’s argument that the institution decision must refer to every bit of evidence that is relied on by the board in its final written decision reflects a misunderstanding of the role of the institution decision in inter partes review proceedings before the board,” said the judge.

The opinion draws a distinction between new grounds for invalidity and new evidence that supports the grounds on which the trial was initiated.   According to Judge Bryson, if the PTAB decision is based on the same grounds, due process is satisfied as long as the opposing party is notified and given a chance to respond.
