She brings experience with technologies ranging from medical devices, streaming media systems and software to projects in the aerospace, automotive, and nuclear energy industries. She also has experience in litigation under the Hatch-Waxman Act, successfully defending generic challenges to patents protecting blockbuster medical therapies. Most recently, Alyssa has been involved in both litigation and counseling involving the legal questions raised by the rapid growth of AI.
The Daily Journal recognized Alyssa as one of the Top Women Lawyers in California in 2023 and both Bloomberg Law and Daily Journal named her to their 40 Under 40 lists.
For Alyssa, IP protection is more than business; it’s personal. For more than a half-century, her family patented mechanical technologies that they developed into a thriving business, inspiring her love of science and technology as well as her desire to protect innovative ideas.

Steve knows how to minimize risk while delivering a client’s business objective, either by defeating an opponent’s case in court or by negotiating the best possible settlement. His ability to pinpoint the argument that will resonate with each judge and jury has enabled him to protect cutting-edge technology involving medical devices, automotive components, telecommunications standards, digital and 3D imaging, guest engagement systems, and semiconductor devices and manufacturing processes. He has also used those same skills in litigating numerous antitrust, unfair competition, and complex tort and contract cases.
For the last 20 years, Steve has focused on guiding Japanese and other Asia-based companies through patent litigation before the U.S. District Courts, ITC and Federal Circuit. He is one of only two lawyers ranked in the Chambers Global guide for having Foreign Expertise in Intellectual Property for Japan. Steve consistently has been described as a “great negotiator who is excellent at creating litigation strategy.” Clients recently interviewed by Chambers also noted, “Steve is a really fantastic tactical thinker with good legal instincts. He is also very collaborative.” Other clients have stated that “his command of the law is evident in his ability to understand it and also apply it across a wide variety of situations,“ while still others have praised his ability to make “very quick and sound tactical decisions.”
