US: Helpful Guidance From Judge Bryson Regarding Stays Pending IPR

Judge Bryson of the Federal Circuit, sitting by designation in the Eastern District of Texas, issued one of the clearest articulations to date in favor of granting a stay pending inter partes review.[1] Notably, in this case, claim construction had ended, discovery was nearly complete, and trial was set to begin in three months. The defendant, Samsung, had recently joined an instituted IPR covering six of the eleven asserted claims and moved to stay the district court proceeding.

Judge Bryson clearly articulated the three factors that district courts consider when analyzing whether or not to grant a stay:
1) whether the stay will unduly prejudice the non-moving party;
2) whether the proceedings had reached an advance stage, including the stage of discovery and whether a trial date is set; and
3) whether the stay will likely result in simplifying the case before the court.

After noting that the congressional intent of post-grant review before the patent office was to be a “quick and cost effective alternative[] to litigation” to provide a “faster, less costly alternative to civil litigation to challenge patents” and to be “an inexpensive substitute for district court litigation that allows key issues to be addressed by experts in the field” he proceeded to walk through the three factors.

US: Estoppel Attaches Even If Dismissed Without Prejudice

On August 16, 2018, the U.S. Federal Circuit addressed when the inter partes review (IPR) time bar clock begins to tick.  See Click-to-Call Tech. LP v. Ingenio, Inc., Slip Op. 2015-1242 (Fed. Cir. Aug. 16, 2018).  The en banc Federal Circuit addressed whether the one year estoppel clock begins for a properly served complaint when the complaint is subsequently dismissed without prejudice.  The panel found that the § 315(b) time bar applies.  The filing of such a complaint, though later voluntarily dismissed, has previously formed the basis for declaratory judgment jurisdiction where the initial defendant later brings a validity challenge. See TransWeb, LLC v. 3M Innovative Props. Co., 812 F.3d 1295, 1300 (Fed. Cir. 2016).

Petitioners bear the burden of proving invalidity of amended claims in IPR proceedings

On October 4, 2017, the Federal Circuit held en banc that the proper interpretation of 35 U.S.C. 316(d) and (e) requires the Petitioner in an inter partes review (IPR) to prove all propositions of unpatentability, including for amended claims.  Aqua Prods., Inc. v. Matal, No. 2015-1177 (Fed. Cir. Oct. 4, 2017).  The en banc Court further determined that the PTAB must consider the entirety of the record when assessing the patentability of amended claims under 318(a), not merely the face of a motion to amend.

The Aqua case resulted in five opinions totaling 148 pages, each presenting views on judgment and underlying rationale, ultimately leading to a narrowly tailored holding.  In the decision, the Federal Circuit made clear that the burden of persuasion of patentability does not rest with the Patent Owner; instead, it is left to the Petitioner to establish that any proposed amended claims are not patentable.

Federal Circuit Confirms Cuozzo Does Not Disturb § 314(d) Bar on Appellate Review of PTAB Reconsideration of IPR Institutions

The Federal Circuit’s recent decision in Medtronic, Inc. v. Robert Bosch Healthcare Systems, Inc., addressed the effect of the Supreme Court’s decision in Cuozzo Speed Techs., LLC v. Lee, 136 S. Ct. 2131 (2016), on the issue of whether termination of instituted inter partes review (“IPR”) proceedings based on a failure to meet the statutory filing requirements for a petition (namely, to identify all real parties-in-interest) would be barred from review by 35 U.S.C. § 314(d). The Court found that Cuozzo did not disturb Federal Circuit precedent as to the § 314(d) bar on review for reconsiderations of institution decisions.
