Jonathan Waldrop

Jonathan Waldrop is a prominent patent litigator and the Chair of Kasowitz's Intellectual Property group, known for representing leading technology companies in complex patent and trademark disputes. His practice spans various technology areas, including interactive web technologies, video-on-demand telecommunications, cable technology, computer-assisted sales processes, medical devices, gaming systems, and complex financial transactions.

While the provided case list shows appearances on behalf of Intellectual Ventures (a patent assertion entity) as plaintiff, Waldrop's broader practice at Kasowitz also includes significant defense work for major technology companies such as Google, LG, ASUS, Uber, Adobe, and Cox Communications. He has been recognized as a "Top Plaintiff Lawyer" in California, indicating a strong presence on both sides of patent disputes, though his firm profile emphasizes representation of industry-leading companies, including those often targeted by patent assertions.

Waldrop has a track record of achieving favorable jury verdicts and significant case dismissals. Notably, he successfully represented Google and YouTube in a case involving claims to interactive web technology, which was widely reported. He also secured a complete dismissal for Google in a six-patent infringement case brought by Data Engine Technologies in the District of Delaware. His representation of Fintiv Inc. against Apple led to the creation of the "Fintiv Rule" at the Patent Trial and Appeal Board (PTAB), a precedent-setting decision allowing discretionary denial of inter partes review petitions based on parallel district court litigation. He has also defeated multiple writs of mandamus to the Federal Circuit regarding venue in patent cases.

Jonathan Waldrop earned his Juris Doctor from the University of Virginia School of Law in 2000 and was admitted to the State Bar of California in 2014. He is regularly recognized by leading legal publications such as Chambers USA, The Legal 500, IAM Patent 1000, IP Stars, Best Lawyers, and Super Lawyers.
