Hsiwen Lo, Ph. D., is a patent litigator in Orrick's Intellectual Property Group. With a Ph. D. in electrical engineering, Hsiwen specializes in cases where a deep understanding of the interplay between technology and legal issues is critical to a company's litigation success.

Hsiwen's representations involve highly-complex technologies, sciences, and mathematics.  Exemplary subject matters include mobile digital processing and publication, three-dimensional graphics rendering, the instruction pipeline of a processor, orthogonal frequency division multiplexing (OFDM), HDL synthesis and verification, and finite-element analysis of mechanical stress and strain.  

Hsiwen has conducted invalidity, non-infringement and infringement analysis. He has handled discovery, drafted expert reports, prepared technical witnesses for deposition, and drafted dispositive and non-dispositive motions. Moreover, he has been involved in case management.  He also advises his clients of issues related to patent portfolio management, IP transactions, and IP-related due diligence review. He is registered to practice before the USPTO (Reg. No. 77,790).   

Hsiwen received his Ph. D. in Electrical Engineering at Caltech. While in Berkeley Law, he focused on patent and intellectual property law. He was the community service chair for Berkeley APALSA. He was also the student liaison and long-time volunteer of the Asian Law Caucus immigration clinic. He received the American Jurisprudence Award.
