Filippos Papadatos

Filippos Papadatos is a Senior Science Advisor and Patent Agent in the Intellectual Property practice at Goodwin Procter, where he has been a member since 2020. His practice primarily involves domestic and international intellectual property portfolio strategy, encompassing the preparation and prosecution of patent applications, drafting opinions on patent validity and infringement, and conducting patentability and freedom-to-operate analyses.

Dr. Papadatos's technical expertise spans a wide range of fields, including semiconductor and microelectronics manufacturing processes, material science, thin-film processing, mechanical engineering, computer software, data processing, artificial intelligence, machine learning, data analytics, and energy. Before joining Goodwin, he served as a Technical Specialist and Patent Agent at Sterne Kessler Goldstein and Fox LLP. His prior experience also includes a decade in the semiconductor industry as a development engineer at IBM and an integration engineer and manager at Samsung Austin Semiconductor.

Based on available case data, Dr. Papadatos's tracked appearances are all on the plaintiff side. He has notably represented Taiwan Semiconductor Manufacturing Company, Ltd. (TSMC) in matters against Advanced Integrated Circuit Process LLC. While his role for TSMC is listed as "plaintiff side" in this context, his work involves challenging patents through inter partes review (IPR) proceedings at the Patent Trial and Appeal Board (PTAB), where TSMC acts as the petitioner. For instance, he has been involved in IPRs such as IPR2025-00830 and IPR2025-01212, filed by TSMC against Advanced Integrated Circuit Process LLC, with one IPR showing a status of discretionary denial. These PTAB actions are often part of a broader defense strategy against patent infringement allegations in district court.

Dr. Papadatos earned his Ph.D. (2006) and M.S. (2002) from the State University of New York, University at Albany, and a B.S. in Physics (2000) from the University of Ioannina, Greece. He is a registered Patent Agent.
