How I represent clients at Schwabe

I bring extensive intellectual property law experience and deep technological knowledge to aid clients in building patent portfolios that support their overall business goals. The clients I represent have diverse technologies, including artificial intelligence (AI) and machine learning, semiconductor devices and processing, software anti-piracy, communication, wearable and IoT devices, speech and handwriting recognition, and image and video processing, among others. With a wide variety of intellectual property experience, I offer services for opinion letters, patent licenses, standard essential patent (SEP) investigation, and strategic patent counseling. I am also a co-developer of an AI application for automatic patent claims analysis.
