Printed Publication? Prove it: IPR Petitioners bear burden of establishing status as prior art

Authors: Jeff Totten and Rachel Elmsley
Editor: Maureen Queler

By statute, prior art in IPRs is limited to patents and printed publications.  Proving a document was published, as well as the publication date, often requires evidence beyond the document’s face.  As recent Patent Trial and Appeal Board decisions illustrate, petitioners ignore the need for this evidence at their own peril.

For example, decisions denying institution in Coalition for Affordable Drugs (ADROCA)LLC v. Acorda Theraputics, Inc., IPR2015-00720 and IPR2015-0817, (August 24, 2015) found the petitioner had not established that scientific posters were prior art publications under 35 U.S.C. § 102(b).  It was undisputed that the posters had been displayed at scientific meetings.  Nonetheless, looking to the Federal Circuit’s In re Klopfenstein decision, the Board noted the record lacked evidence establishing: Continue reading

PTAB Proposes Amendments to its Rules of Practice

Author: James Stein
Editor: Aaron Capron

On Wednesday, the U.S. Patent and Trademark Office (USPTO) released a much-anticipated proposed rule package in response to public feedback, making what it calls “more involved” changes to the rules governing Patent Trial and Appeal Board trial proceedings. 80 Fed. Reg. 50720 (Aug. 20, 2015). Some of the proposed changes may benefit patent owners, like allowing submission of new testimonial evidence before institution and replacing petition page limits with word count limits. The new rules would also expressly define a duty of candor and good faith for all parties and practitioners appearing before the Board. The proposed changes also codify some of the Board’s current practices, such as applying the broadest reasonable interpretation to patent claims that will not expire before a final written decision and requiring the parties to serve demonstratives with more time to work out disputes before oral hearing.

The USPTO is soliciting comments on the proposed rule package until October 19, 2015. A detailed breakdown of the rules can be found as an IP Update on Finnegan’s website.
