The Patent Office today issued a press release of its notice of proposed rulemaking that would replace the broadest reasonable interpretation standard the Patent Trial and Appeal Board applies to construe unexpired patent claims and proposed substitute (amended) claims in AIA trial proceedings with the Phillips standard applied in patent cases before federal district courts and the International Trade Commission (ITC). The Office also proposes to amend the rules “to add that the Office will consider any prior claim construction determination concerning a term of the involved claim in a civil action, or an ITC proceeding, that is timely made of record in an [AIA trial] proceeding.” Any proposed changes adopted in a final rule would be applied retroactively to pending AIA trials.

In late March, the Federal Circuit issued an order staying the PTAB proceedings concerning numerous related IPRs of patents issued to Allergan, Inc. (“Allergan”), but assigned to the Saint Regis Mohawk Tribe (“the Tribe”). These IPRs were headed toward a final hearing on the merits previously scheduled for April 3rd. In those IPRs, the PTAB denied the Tribe’s motions to terminate the proceedings based upon the Tribe’s sovereign immunity. Mylan Pharma Inc. v. Saint Regis Mohawk Tribe, Case IPR2016-01127, Paper 130 (February 23, 2018). This post explains the PTAB’s decision that the court will now review on appeal.

In MaxLinear Inc. v. CF Crespe LLC the Federal Circuit ruled that the PTAB did not address arguments concerning patentability of certain dependent claims of the patent at issue separate from the corresponding independent claims, and vacated and remanded the PTAB’s final written decision.

The Board recently granted a motion to amend, to replace unpatentable claims with proposed substitute claims, a rare occurrence that may signal a change compelled by Aqua Products (summarized here). In Apple, Inc. v. Realtime Data, LLC, Case No. IPR2016-01737 (PTAB March 13, 2018), the Board determined that all challenged claims were unpatentable and then granted the patent owner’s contingent motion to amend with respect to all proposed substitute claims.  Based on a USPTO study on motions to amend (see Graph III here), only four motions to amend substituting claims were granted in full before September 30, 2017, mere days before the Federal Circuit issued its en banc decision in Aqua Products.

On April 24, 2018, the Supreme Court issued its decision in SAS Institute, Inc. v. Iancu, holding that if the Patent Office institutes an inter partes review (IPR) proceeding, it must issue a final written decision with respect to the patentability of every patent claim challenged by the petitioner. The Court reversed the Federal Circuit’s judgment, which upheld the Patent Trial and Appeal Board’s (PTAB) common practice of instituting review on some, but not all challenged claims, and then issuing a final written decision addressing only the claims for which review was instituted.

The equitable doctrine of collateral estoppel protects a party from having to re-litigate an issue that has already been fully and fairly adjudicated. In Nestlé USA, Inc. v. Steuben Foods, Inc. the Federal Circuit said that application of collateral estoppel is not limited to construing only identical patent claims; but instead, it extends to terms across related patents. Case No. 2017-1193 (Fed. Cir. Mar. 13, 2018).

A patent relating to a method of treating rheumatoid arthritis using rituximab recently survived its fourth IPR challenge. Celltrion, Inc. v. Biogen, Inc., IPR2016-01614 (PTAB Feb. 21, 2018). The PTAB determined that the Petitioners failed to establish that the challenged claims of the patent were obvious over prior art, in part, because of the Petitioners’ failure to establish the prior art status of the product label for RITUXIN®, which contains rituximab.

On February 9, 2018, the PTAB denied Sandoz Inc.’s petition for inter partes review of U.S. Patent No. 9,512,216, a patent owned by AbbVie Biotechnology Ltd. The patent recites methods for treating moderate-to-severe chronic plaque psoriasis with adalimumab, a human anti-tumor necrosis factor α (TNFα) antibody.  The methods of the claimed invention involve subcutaneously administering to a patient an initial dose of 80 mg of adalimumab, followed by 40 mg of adalimumab every other week starting one week after the initial dose.  The patent is one of several patents AbbVie owns that relate to its blockbuster autoimmune drug Humira.

Serial IPR petitions directed to previously-challenged patents account for many of the petitions filed with the PTAB; however, 35 U.S.C. § 325(d) provides the Board with discretion to reject petitions where the same, or substantially the same, prior art or arguments have already been presented to the USPTO.  The Board recently designated as precedential part of its decision in General Plastic Industrial Co. v. Canon Kabushiki Kaisha, Case IPR2016-01357, Paper 19 (6 September 2017), addressing factors to be considered in determining whether to institute review for a serial, or “follow-on” petition.  Petitioner General Plastic filed a first set of petitions seeking IPR of U.S. Patent No. 9,046,820 B1 (“the ’820 patent”) and U.S. Patent No. 8,909,094 B2 (“the ’094 patent”).  Institution of a trial was denied for each petition based upon the merits.

March 13, 2018, marked the fifth anniversary of the transition from the previous “first to invent” system to the AIA’s “first to file” regime.  The PTAB seemingly marked the occasion by instituting the first ever derivation proceeding one week later in Anderson Corporation v. GED Integrated Solutions, Inc., Case DER2017-00007, Paper 32 (March 21, 2018).

The concept of “derivation” was not created by the AIA.  Pre-AIA 35 U.S.C. § 102(f) dictated that a person shall not be entitled to a patent if he did not himself invent the claimed subject matter.
