District of Delaware Considers Physical Products & Redundant Publications

Back in August, I pointed out that district courts continue to grapple with whether or not physical products described by prior art publications of an earlier Patent Trial & Appeal Board (PTAB) trial are subject to 315(e)(2) estoppel. That is, by virtue of utilizing a product manual in the earlier PTAB proceeding, whether the actual products corresponding to such a manual can be considered “raised, or reasonably could have been raised” under 35 U.S.C. § 315(e)(2).

The view of some districts has been that since physical products can’t be raised at the PTAB, such evidence is simply outside the scope of estoppel.  Others take a narrower view, weighing the potential technical superiority of the physical product to the previously used publication.  In another twist on this fact pattern, the District of Delaware recently considered whether the underlying evidence of these disputes should be the focus at all.

Arthrex Argument Being Added to Briefs

As detailed back in December, the government has sought en banc rehearing in Arthrex. In its petition, the government revisited the bases for the Court’s October decision and encouraged the Court to also grant rehearing in the Polaris dispute so that the court might address forfeiture in Arthrex and reach the remaining issues in Polaris (which is distinguished in the petition as having seasonably argued the issue before the agency).

In its Reply of last week, the government once again focuses on forfeiture, arguing that raising an Appointments Clause issue on appeal is too late.  To emphasize the issue, the Reply lists all of the newly filed appeals raising the issue for the first time.

Adding New Blood into the Estoppel Mix

IPR estoppel under 35 U.S.C. § 315(e)(2) provides that “the petitioner in an inter partes review of a claim in a patent . . . that results in a final written decision . . . may not assert . . . in a civil action . . . that the claim is invalid on any ground that the petitioner raised or reasonably could have raised during that inter partes review.” (emphasis added).  As pointed out previously, a growing number of district courts have construed the phrase the “reasonably could have raised” aspect of 35 U.S.C. §§ 315(e)(2) to define grounds that a party could have included in its petition, but did not.

Assuming a failed petitioner can locate a piece of prior art that it could not have raised earlier (and make the appropriate showing to avoid estoppel) are combinations with failed art of the IPR precluded?

New Tactics & Risks for Litigators

On Monday, I laid out my Top 5 PTAB cases of 2019 for PTAB Practitioners, focusing on those cases that changed day-to-day practices before the agency. Like Monday’s list, my Top 5 PTAB developments of 2019 for District Court Litigators will focus on those practical developments that will impact related litigation practices outside of the agency.

In 2019, there were a number developments of interest to litigators, from tricks to avoid the PTAB altogether, to new risks on fee awards and estoppel.

PTAB 2019: A Year of New Precedent

There were a number of high profile developments at the Patent Trial & Appeal Board (PTAB) in 2019. New procedures for amending claims, Practice Guide updates to thwart parallel petition filings, a successful constitutional challenge based on the Appointments Clause, and another SCOTUS review of the PTAB appeal bar.  But, not all of these developments impact the day-to-day life of PTAB practitioners.  Of greater interest to PTAB practitioners are the developments that change the game for the average AIA trial, with this in mind, below are my Top 5 PTAB Practitioner Developments of 2019.

Totality of Circumstances for Determining Public Accessibility

Over the years, the Patent Trial & Appeal Board had become panel dependent in assessing questions of public accessibility at institution.  Some panels seemed to require a showing of a likelihood of public accessibility to move forward, while others  required a more definitive showing.  Last spring, the Precedential Opinion Panel (POP) took up this growing rift in institution standards in Hulu, LLC v. Sound View Innovations, LLC, Case IPR2018-01039. Specifically,  the  POP addressed the requirements for establishing that a reference qualifies as a printed publication at the time of institution.

In its now precedential decision, the Board found that a more flexible approach was needed at institution.

Gov’t Questions Fundamental Aspects of Court Decision

As promised, the government has now sought en banc rehearing in Arthrex. In its petition, the government revisits the bases for the Court’s October decision and encourages the Court to also grant rehearing in the Polaris dispute so that the court might address forfeiture in Arthrex and reach the remaining issues in Polaris (which is distinguished in the petition as having seasonably argued the issue before the agency)

I think it is safe to predict the CAFC takes this one up.Continue Reading En Banc CAFC to Debate PTAB Appointments Clause Issue
