Christopher M. Caira

Christopher M. Caira is an attorney with experience in patent litigation, holding an "of counsel" role at Kheyfits & Caira. His practice, based on available case data, involves representing patent holders in disputes.

Caira's experience includes handling cases related to content synchronization technology for multi-room audio systems and other software-based inventions. His known appearances indicate a focus on the plaintiff side, with one tracked appearance representing a patent owner against an alleged infringer.

A notable engagement for Mr. Caira was his representation of Implicit, LLC in its patent dispute against Sonos, Inc.. This case centered on U.S. Patent Nos. 7,391,791 and 8,942,252, covering methods and systems for synchronizing content rendering. The litigation involved significant activity at the Patent Trial and Appeal Board (PTAB), where Sonos, Inc. successfully challenged the patents in inter partes review (IPR) proceedings, leading to findings of unpatentability. The case further progressed to the U.S. Court of Appeals for the Federal Circuit, which affirmed the invalidity of the asserted patent and the PTAB's decision to deny Implicit's attempt to use post-decision inventorship corrections to introduce new antedating theories, citing forfeiture. This experience highlights his involvement in complex patent validity challenges and appellate proceedings concerning PTAB outcomes.
