Betty has nearly two decades of experience successfully representing tech companies in more than 130 high-stakes Hatch-Waxman, trade secret, antitrust, breach of contract, fraud, and patent cases. She has taken approximately 20 cases to trial in a variety of forums across the country, including federal district courts, state courts, and the International Trade Commission. Betty’s practice also focuses on strategic patent prosecution and portfolio management, as well as IP due diligence — particularly in the pharmaceutical and medical device space — for major mergers and acquisitions.  Her clients’ products include 5G wireless communication infrastructure, software and applications, medical devices and parts, semiconductors, hardware, consumer electronics, and other cutting-edge technologies.
 
Betty is an innovative, zealous, and talented trial lawyer with extensive courtroom experience, legal acumen, and a deep understanding of the technologies that underlie her clients’ products. Armed with these skills, she has achieved an impressive record in successfully litigating contentious, bet-the-company cases.  For example, on the defense side, her sophisticated legal strategies have helped numerous clients defeat claims with summary judgments, full-defense jury verdicts, and voluntary dismissals of plaintiff claims in multimillion-dollar disputes.  On the plaintiff’s side, Betty has helped her clients win tens of millions in damages.
 
Betty has been identified for “Litigation - Intellectual Property” by Best Lawyers (2024-2025), “IP Star” by Managing IP (2022-2024), and “Top Intellectual Property Lawyers in California" by the Daily Journal (2022-2023).  Betty was selected as a Federal Circuit “Global Fellow” for 2022-2023, which identifies 24 attorneys around the world who are “members of the next generation leaders in patents.”  Betty was also the recipient of the American Bar Association’s 2020 “Top 40 Young Lawyers” and “On the Rise” award, given to members of the organization who have demonstrated a broad range of high achievement, innovation, vision, leadership, and service to the profession and community. She was also named one of Legal Momentum’s “Women of Achievement” and as a National Asian Pacific American Bar Association “Best Lawyers Under 40” in 2020. Throughout the years, she has received other accolades from organizations and publications such as “40 Under 40” by the Silicon Valley Business Journal, “Diversity Leader” by Profiles in Diversity Journal, “Rising Star” by Super Lawyers, and many more.
 
She is an active member of several legal organizations, including the Asian Law Alliance, the Asian Pacific American Bar Association of Silicon Valley, and NAPABA.  In the community, Betty regularly provides pro bono counsel to Kids in Need of Defense, an organization that helps unaccompanied immigrant children navigate asylum and immigration proceedings and find refuge in the U.S.
