Looking back on the major developments that have shaped AIA proceedings over the first four years, three sources have contributed to changes: (1) rulemaking, (2) informative decisions by the PTAB, and (3) key appellate decisions of the US Supreme Court and the Court of Appeals for the Federal Circuit. While a number of improvements have been made, there is still more change to come, as the USPTO seeks to establish the right balance between petitioners and patent owners. Continue reading this entry
In what appears to be a case of first impression, the PTAB is poised to rule on the question of whether state sovereign immunity prevents an IPR challenge from being maintained against a University of Florida (“UF”) patent (IPR2016-01274). Under the 11th Amendment to the Constitution, “[t]he Judicial power of the United States shall not be construed to extend to any suit in law or equity, commenced or prosecuted against one of the United States by Citizens of another State, or by Citizens or Subjects of any Foreign State.” State university patent owners who have availed themselves of the remedies offered by infringement litigation in federal courts, have still been able to use the sovereign immunity shield of the 11th Amendment to prevent other suits against them challenging validity of their patents (see “Critics Take Aim At Califorinia’s Patent Shield”). While the use of state sovereign immunity as a shield in patent litigation is not new, this appears to be the first instance of it being asserted as a defense in an IPR or AIA proceeding.

In a case that appears to be a case of first impression, the PTAB found in its decision denying institution in IPR2016-00781 that a final written decision in an earlier IPR created estoppel under 35 U.S.C. § 315(e)(1), preventing a second IPR petition from being instituted that used additional references which reasonably could have been raised before, even though the Petitioner explained how the new references were missed by the first search. In addition, the PTAB further denied institution using its discretion under 35 U.S.C. § 325(d) because the unpatentability grounds were essentially the same as in the earlier petition, although additional references were included.

In a rare grant of a petition for rehearing en banc, the court decided that an appeal “warrants en banc consideration” of who bears what burden when amending in an IPR. In re: Aqua Products, No. 15-1177, slip op. at 2 (Fed. Cir. August 12, 2016). From the very beginning of IPRs, the Patent Trial and Appeal Board has required the patent owner to bear the burden on a motion to amend. Idle Free Sys., Inc. v. Bergstrom, Inc., IPR2012-00027 (PTAB June 11, 2013). That is, when a patent owner during an IPR filed a motion to amend its claims, the Board required the patent owner to prove the patentability of its amended claims. Id. That requirement might soon change. Continue reading this entry
Yesterday, the Court of Appeals for the Federal Circuit (CAFC) held in In re Magnum Oil Tools International (Newman, O’Malley & Chen) that the burden of production to show unobviousness does not shift to a patent owner based upon the Board’s institution decision. In particular, the CAFC found that Cuozzo’s prohibition of appealing institution decisions does not prevent patent owners from appealing a final written decision based on a failure to establish prima facie obviosuness, even though the final written decision rests upon an institution decision that was not challenged in a request for rehearing on such basis.

The USPTO’s Patent Trial & Appeal Board (PTAB) hosted its June Boardside Chat, which addressed best practices for presenting patentability/unpatentability arguments before the board. The Chat, which was hosted by Administrative Patent Judges (APJs) Jay Moore, Christopher Crumbley, and Kal Deshpande, provided valuable guidance for best-practices in the context of IPR proceedings.

The PTAB recently stood firm in denying a petitioner’s motion to change the filing dates of two IPR petitions that missed a statutory deadline by less than ten minutes. Case IPR2016-00281 and IPR2016-00282 (Patents 8,603,514 B2 and 8,017,150 B2). The petitioner, Teva Pharmaceuticals USA, Inc., was facing a 1-year statutory IPR filing deadline of December 3, 2015, set by a complaint alleging patent infringement served on Teva a year earlier.

We have reviewed a sub-group of 111 IPRs filed by generic drug companies against pharmaceutical patents to assess outcomes and trends. While our survey was not intended to capture every IPR filed by a generic drug company, it does cover the most active generic company filers to date (see Fig. 2 below). Examining this particular group of IPR petitioners, we found an institution rate of 67%, which is not significantly different from the general rate of institution across all technologies, showing that generic companies are achieving a comparable institution rate. There is also a very high settlement rate of 23% (combined pre- and post-institution settlements out of total outcomes), with pre-institution settlements counting for 17% of all outcomes (see Fig. 1 below). While a greater number of these IPRs resulted in a finding of all instituted claims being patentable in final written decisions (FWDs) compared to IPRs across all technologies, the sample size of FWDs is so small (9 IPRs in Fig. 1) that it may be premature to read too much into this.

Many patent owners have not yet had to defend against an inter partes review (IPR), but the popularity of this proceeding increases the chances that they will encounter it down the road if they have not already faced one. This article explores IPR proactive defense measures that may be useful for patent owners to deploy in advance of facing an IPR. Continue reading this entry
The U.S. Department of Justice (DOJ) filed six petitions for inter partes review (IPR) of three patents assigned to Discovery Patents, LLC. The patents cover security alarm systems and methods for providing secure real-time video and imaging to emergency response agencies over a high speed communication link. The challenged patents are USPs 6,798,344, 6,778,085 and 7,323,980.
The DOJ’s attack on private sector patents is unusual, but not unprecedented.
DOJ Has Used IPR Before In Response To Litigation Asserting Patents Against the US Government
This is the DOJ’s second time filing IPRs – in January 2016, the DOJ petitioned for review of Iris Corp.’s U.S. Patent No. 6,111,506 for passport identification technology (IPR2016-00497). Iris Corp. had previously sued the government in the U.S. Court of Federal Claims for infringement prior to the DOJ’s IPR petition against its patent.
Likewise, Discovery Patents, together with licensee 3rd Eye Surveillance, LLC, filed suit last year in the U.S. Court of Federal Claims, alleging that the U.S. government infringed its patents (Case 1:15-cv-00501-CFL, filed 5-15-2015). Specifically, Discovery Patents and 3rd Eye contended that the U.S. government maintained infringing security systems in airports, government buildings, and national border areas.
The DOJ’s petitions against Discovery Patents (and Iris Corp. earlier in the year) illustrate one of the risks a patent owner faces when asserting its patent — namely, that the accused infringer may react by filing an IPR and potentially invaliding the patent. Here, the patent owner faces the DOJ, which has more than two dozen registered patent practitioners, according to a search of the Patent Office’s records, and which submitted a lengthy declaration from a digital video expert whose standard consulting rate is $500 / hour.
A Prelude to Settlement?
The DOJ is not the first to challenge Discovery Patents. One of the patents was the subject of IPR proceedings which ended last year — Stealth Monitoring, Inc. had petitioned for review of the ‘980 patent, and the parties settled and terminated proceedings prior to institution of the IPR. Here, the DOJ petitions include at least some of the same prior art used by Stealth Monitoring to challenge the claims of the ‘980 patent. Thus, filing the IPRs may provide leverage for a potential settlement.
With these IPR petitions, the DOJ can counter private sector patent owners accusing the government of infringement. The government is sometimes on the other side, though, as the patent owner. For example, the government owned the patent that was the subject of the first-ever motion to amend granted in an IPR, where the Secretary of Agriculture represented the government rather than the DOJ.
Further, other agencies of the US government have previously played a different role in inter partes proceedings — that of an active competitor. For example, the NIH has filed inter partes reexaminations against biotechnology patents in the past (see e.g., Reexam Control No. 95/000,062). The NIH has obtained many life sciences related patents and is actively involved in transferring technology to the private sector.
DOJ Has Been Active In Patent Reform Hearings
In 2002, the DOJ sponsored hearings on competition and innovation (see https://www.ftc.gov/news-events/events-calendar/2002/02/competition-ip-law-policy-knowledge-based-economy-hearings), which led to a number of recommendations taken up in Congress and a first set of patent reforms under the American Inventor’s Protection Act (AIPA), which created inter partes reexams. This was a precursor to the newer inter partes review procedures available since September 16, 2012 under the America Invents Act (AIA) and a further set of patent reforms enacted by Congress.
More than 4,100 IPR petitions have been filed since September 16, 2012. The DOJ has filed just a handful, and these petitions mark its first forays as petitioners in AIA proceedings. (The IPR petition numbers are IPR2016-01035; IPR2016-01037; IPR2016-01038; IPR2016-01039; IPR2016-01040 and IPR2016-01041.)
