Favorable Trends For Patent Owners Post-Aqua Products

November 21, 2019 | Blog | By Daniel Weinger, Vincent Ferraro, Chris Duerden

When former President Barack Obama signed the Leahy–Smith America Invents Act into law on Sept. 16, 2011, the patent system in the United States underwent one of its most sweeping and significant overhauls. The AIA replaced the then-existing post-grant review proceeding of inter partes reexamination with several new proceedings known as inter partes review, post grant review and covered business method patent review. Congress implemented AIA reviews to streamline disputes over patent validity, with the goal of reducing costs for all involved. In October 2017, the U.S. Court of Appeals for the Federal Circuit in Aqua Products Inc. v. Matal shifted the burden by putting it back on the challenger to prove unpatentability.

ICON Health & Fitness promulgated a “totality of the circumstances test” for awarding reasonable attorney fees to the prevailing party in exceptional cases under 35 U.S.C. §285.  As lower courts have applied this standard, it has become clear that the motivation and conduct of the losing party is a focal point of the exceptionality analysis.  However, two recent decisions emphasize that bad faith arguments and litigation tactics—by both parties and in all stages of litigation—are critical to the exceptionality analysis in Section 285 attorney fee awards.

Key Considerations for Global SEP Litigation - Part 2

November 5, 2019 | Blog | By Michael Renaud, James Wodarski, Matthew Galica

The adoption of multiple, standardized technologies looms on the horizon.  This presents the challenge of balancing innovator’s intellectual property rights with implementer’s desire for fair access to technology. As more implementers adopt efficient infringement to circumvent this equilibrium altogether, standard-essential patent (“SEP”) licensing disputes have increased.

Judge Gilliam of the Northern District of California recently answered this question and provided helpful guidance on the interplay of IPRs, reexaminations and district court litigation.

Apple Inc., Judge Gilliam denied plaintiffs’ (“IXI”) motion for leave to amend their infringement contentions and asserted claims because IXI was not diligent in identifying new contentions or new accused products.

October 25, 2019 | Blog | By Daniel Weinger, Vincent Ferraro
