What does it mean for prior art to be reasonably discoverable for purposes of IPR estoppel?

In a recent decision, the Federal Circuit clarified the “skilled searcher” standard, holding that simply finding a reference among thousands of search results is not enough to establish that it reasonably could have been discovered. The court also emphasized the need to account for hindsight when evaluating whether prior-art grounds are subject to estoppel.

In a recent Litigation Blog post, Douglas Wentzel and Ethan Kluesner examine the decision and what it means for parties assessing prior-art searches and IPR estoppel.

Knobbe Martens was proud to host our inaugural Diversity and Affinity Group Summit last week, bringing together colleagues from across our firm for an afternoon focused on strengthening relationships, building community, and networking with one another.

The half-day program featured a business development workshop led by Marketing, Brand and Business Development Strategist Toni Wells; a panel discussion on strategies for career success with firm partners Mark Lezama, Ben Shiroma, Rosaleen Chou, and Maria Stout; and a trivia competition. The Summit culminated in a social hour, providing an opportunity for colleagues to connect and continue the conversations from throughout the day.

The relationships and insights gained from the Summit will extend well beyond the afternoon, and will help guide how we support one another and our clients. Thank you to everyone who helped make the Summit a success!

In his comments, Jarom highlights how examiner analytics can help practitioners develop more informed strategies throughout the application process—from tailoring claim language to determining when an appeal may be appropriate.

Can a drugmaker be held liable for delaying the release of a potentially safer alternative to an existing drug? The California Supreme Court recently said no, finding that drug manufacturers have no duty to commercialize a safer alternative to a nondefective drug.

In our latest Biotechnology Blog post, Ari Feinstein and Rhett Ramsey examine the decision and its implications for pharmaceutical companies navigating product development, innovation, and IP strategy.
