Sergio’s practice focuses on patent litigation, prosecution and client counseling in the fields of telecommunications, electronics, semiconductors, business-methods, electronic commerce, medical devices, industrial equipment/machines, packaging, and consumer products. Sergio’s experience includes preparing and prosecuting patent applications in the U.S. and abroad; initiating and defending reexamination proceedings at the U.S. Patent and Trademark Office; representing clients in patent infringement suits; providing patentability, invalidity and non-infringement opinions; developing patent assets for assertion and licensing programs; evaluating intellectual property assets in the context of litigation, mergers, acquisitions, and investments; and providing intellectual property due diligence for various types of transactions.

Additionally, prior to obtaining his law degree, Sergio worked for an IP research and analysis firm, where he conducted patent validity, freedom-to-operate, and patentability research. He also researched and analyzed the patent landscape in particular technology areas to help clients make key R&D decisions, evaluate acquisition opportunities, identify business opportunities, and create valuable IP portfolios.
