Matthew advises clients on patent matters with a deep understanding of the value of patents, combining his business, technical, and legal acumen.
As former Director of Intellectual Property (IP) at SRI International, a research and innovation company based in Silicon Valley, and several other companies, Matthew has extensive in-house and law firm experience in all phases of a patent’s life cycle, from working with inventors to making strategic decisions on patent filing to monetizing patent assets. These experiences allow him to better understand clients’ needs and value their successes as his top priority.
Matthew brings 26 years of experience in technology development, patent drafting and prosecution, intellectual property management, and patent acquisition. His practice concentrates on patent drafting and prosecution of utility and design patents, patentability and freedom-to-operate studies, trademark registration, IP due diligence, IP litigation support and IP licensing. His academic training in electrical and computer engineering, coupled with prior industry experience as a scientist and engineer, affords him an in-depth understanding of complex technologies behind his clients’ innovations.
Matthew is well-versed in blockchain technology and deeply rooted in engineering and research. He is a contributor to the engineer community’s understanding of IP protection. He lectured a course entitled “Intellectual Property Rights: Protection, Enforcement and Risks” at the Fifteenth International Summer School on Advanced Computer Architecture and Compilation for High-Performance and Embedded Systems, July 14-20, 2019, Fiuggi, Italy. He has authored a book titled Fundamentals of Patenting and Licensing for Scientists and Engineers, World Scientific, 2008 and 2015, which have been used as a textbook for patent and innovation courses at UC Berkeley, Tsinghua University, University of Oslo, Rochester Institute of Technology, and IEEE. Matthew is editor-in-chief and a contributing author of a Chinese book titled Handbook of Best Practices in Intellectual Property Management, Enterprise Management Publishing, 2011. He has also published two online tutorials on patent protection for engineers with the IEEE eLearning Library.
During 2005-2021, Matthew was Associate Editor of International Journal of Pattern Recognition and Artificial Intelligence. During 2011-2013, he was appointed by UC Berkeley and Tsinghua University to teach a course “Patent Strategy and Innovation” at Tsinghua University, Beijing. He has also served as Chief Advisor, Intellectual Property to Office of Enterprise Management Job Training & Certification, Chinese Enterprise Confederation from 2011-2014.
Prior to his transition into intellectual property, Matthew spent 15 years in corporate research, mostly with Panasonic R&D Company in the United States as a senior scientist working on artificial intelligence, machine learning, signal and document analysis, home networking, and telecommunications technologies. He is an inventor of 14 U.S.-granted patents and is an author of 30 refereed conference and journal papers. He has also published two technical books on recommendation systems and mobile multimedia processing.
Prior to joining Wolf Greenfield, Matthew held various roles in the intellectual property field. Most recently, he was a patent attorney at an international law firm, where he drafted and prosecuted patent applications in the electronics and software space.
