Supreme Court Oral Argument Review: The Justices Appear Split in Thryv v. Click-to-Call

The Supreme Court heard oral arguments in Thryv v. Click-to-Call Technologies last month. As we previously discussed, the case concerns whether the PTAB’s finding that a petition for IPR was timely filed is reviewable on appeal. If the Justices’ questions at oral arguments are any indication, a split decision is likely.

At issue in the case is Section 314(d) of the Patent Act, which bars appeal of the PTAB’s decision “to institute an inter partes review under this section.” The Justices must decide whether that statute applies to, and thus bars appeal of, the PTAB’s finding that the petitioner timely filed the petition before the end of Section 315(b)’s one-year window.

The Federal Circuit Provides a Roadmap for Using Articles in IPR

Posted by Turhan Sarwar on Dec 20, 2019

Too often some challenger in IPR declines to use non-patent literature (or “NPL”), such as academic and trade journal articles, because of the effort and risk associated with establishing that the NPL is prior art. The Federal Circuit’s recent decision in Telefonaktiebolaget LM Ericsson V. TCL Corp. (No. 17-2381) illustrates why that strategy can be a mistake and provides guidance on how to use NPL effectively.

As we have discussed, the PTAB often imposes specific requirements for establishing that an NPL reference is a prior art printed publication. Unlike with patent prior art, where challengers can ordinarily rely on the dates on the document itself, challengers typically have to introduce evidence that NPL was publicly accessible early enough to make it prior art. Getting that evidence can be challenging, which is why some challengers shy away from using NPL at all.

Can Amendment Save Your Claims in IPR?

In the past, moving to amend the challenged claims during IPR was largely futile. The PTAB denied nearly all motions to amend, and many patent owners that might have benefited from amendment chose not to pursue it. But the rules concerning amendment in IPR are changing, and the number and success rate of motions to amend are ticking up. Patent owners have new reasons to think that amendment might save their patents from IPR.

Continued Uncertainty About Estoppel Highlights the Importance of Preparing Carefully

Posted by Anant Saraswat on Nov 19, 2019

Challengers in post-grant proceedings like IPR may not reassert invalidity arguments in court that they “raised or reasonably could have raised” before the PTAB. Several recent cases illustrate that whether a particular invalidity argument “reasonably could have [been] raised” is a fact-intensive question that the parties must be prepared to address. These cases also show that both patent owners and challengers should develop a factual record relating to whether estoppel applies to a given invalidity theory.

PTAB Panel Denies IPR Institution Under § 314(a) in View of Parallel District Court Litigation

Posted by Elizabeth DiMarco on May 24, 2019

Elizabeth DiMarco

For months, panels at the PTAB have debated the relevance of parallel district court litigation on the PTAB’s discretion under 35 U.S.C. § 314(a) to institute or deny a petition for IPR. On May 7, 2019, the PTAB designated as precedential the NHK Spring Co. v. Intri-Plex Techs. decision that denied institution under § 325(d) and § 314(a), confirming that district court litigation “nearing its final stages” is indeed one relevant factor in deciding whether to institute an IPR.

The Internet is Forever: Costs of Oversharing Online

Posted by Matthew Beyersdorf on May 23, 2019

A critical and early determinant in any procedural review is an examination of the permissibility of individual pieces of evidence. In matters of intellectual property, and particularly in IPRs, the permissibility of evidence often rests on two factors: whether a printed publication was publicly available and the relevant dates of that availability. As more and more companies disseminate disclosures and company information on the internet as a matter-of-course, the determination of both factors is becoming increasingly challenging to parse.

Did I Say That? The Narrow Divide Between § 102 and § 112 Arguments

Posted by Jessica von Reyn on May 17, 2019

Jessica von Reyn

While a line of argument in an IPR may seem promising to a patent owner addressing one particular ground of rejection, it is critical for the patent owner to analyze how the argument may impact other grounds of rejections. A seemingly necessary position against one ground may result in substantially limited options for the patent owner with respect to other rejections. While IPR proceedings are limited by statute to prior art challenges (novelty and obviousness), contingent amendments (substitute claims) are also subject to further analysis (such as scope and written description support). In a recent decision, the PTAB rejected a patent owner’s §§ 102 and 103 arguments relating to substitute claims, and then proceeded to perform an alternative analysis under § 112 (written description), finding that the outcome would not change, in part, because of the patent owner’s own § 102 argument.

Isn’t it Obvious to Optimize for Better Results?

Posted by Joshua Brandt on Apr 23, 2019

Just because your issued patent was examined by the USPTO does not mean that it is free from challenge. Your competitors may, of course, scrutinize your patent and use IPR to challenge its validity—potentially turning your patent shield into a roadmap to their next product. This was the case in a recent IPR.

The Patent Office POPs the Door Open for Same-Party Joinder

Posted by Kevin Mosier on Apr 1, 2019

In September 2018, the Patent Office created the Precedential Opinion Panel (or “POP”) to increase transparency and predictability of proceedings before the PTAB by establishing precedent that would guide all PTAB judges. In March 2019, the POP released its first opinion, which held that the PTAB may, in limited circumstances, join both a petitioner to a proceeding in which it is already a party and join new issues to an existing proceeding.

Lack of Redundancy May Not Be Enough to Justify Follow-On Petitions for IPR

Posted by Elizabeth DiMarco on Feb 22, 2019

Elizabeth DiMarco

In the 2017 precedential decision General Plastic Co. v. Canon Kabushiki Kaisha, the PTAB established a set of seven non-exclusive factors  that it will consider in exercising its discretion under 35 U.S.C. § 314(a) to deny follow-on petitions. Two recent PTAB decisions analyzing General Plastic suggest a lack of redundancy between the petitions may not be enough to justify instituting a follow-on petition.  Instead, a primary consideration guiding the PTAB may be whether the petitioner could have raised the arguments in an earlier-filed petition.
