ILS Welcomes Former OCBA President Mei Tsang to Lead Intellectual Property Practice, Accelerating Global Expansion
ILS LLP is proud to announce that Mei Tsang, Esq., a prominent Southern California intellectual property attorney and former President of the Orange County Bar Association (OCBA), has joined the firm as Partner and Head of IP Practice Group.
The appointment marks a significant expansion of ILS’s intellectual property capabilities and underscores the firm’s broader strategy to attract top legal talent, strengthen its core practices, and build a next-generation global law firm.
With more than 25 years of legal and business experience, Tsang brings a formidable combination of high-stakes IP litigation experience, global intellectual property strategy, and law firm leadership. A respected figure in Southern California’s legal community, she served as President of the OCBA in 2025.
“We’re not building a bigger version of a traditional law firm. We’re building the next generation of global law firms, powered by exceptional talent and a commitment to delivering real business value,” said Richard Liu, Esq., Managing Partner of ILS.
“Mei embodies exactly what we’re looking for. Her track record, leadership, and business acumen make her an extraordinary addition to our team. And we’re just getting started.”
Protecting Innovation. Driving Business Value.
In today’s competitive marketplace, intellectual property is more than a legal asset. It can determine a company’s market position, growth potential, and long-term enterprise value. Few attorneys understand that intersection of law and business as deeply as Mei Tsang.
Throughout her career, Tsang has advised U.S. and international businesses on protecting, managing, and commercializing their intellectual property. Her practice spans global patent, trademark, and copyright portfolio development, IP licensing, strategic transactions, and cross-border enforcement.
When disputes arise, she brings extensive courtroom experience. As lead counsel, Tsang has handled complex, high-stakes disputes involving patents, trademarks, copyrights, and trade secrets. She has represented clients in federal and state courts, proceedings before the Trademark Trial and Appeal Board (TTAB), and international IP enforcement matters.
Her perspective extends well beyond litigation. Having owned and operated a law firm and led intellectual property practices for more than a decade, Tsang understands the commercial realities behind legal decisions. She has also served as outside general counsel, working closely with executives to navigate business challenges, assess risks, and align legal strategies with long-term growth objectives.
From building global IP portfolios to defending valuable innovations in court, Tsang helps businesses turn intellectual property into a lasting competitive advantage.
A Recognized Leader in Southern California’s Legal Community
Tsang’s reputation extends beyond her work in intellectual property law.
In 2025, she served as President of the Orange County Bar Association, one of Southern California’s prominent legal organizations.
She currently serves as President of the OCBA Charitable Fund and previously served as President of Community Legal Aid SoCal and Chair of the OCBA Intellectual Property and Technology Law Section.
Her leadership reflects a longstanding commitment to advancing the legal profession, mentoring attorneys, and expanding access to legal services.
Her professional achievements have earned recognition from leading legal publications and organizations, including:
The Best Lawyers in America® | Copyright Law (2021–2027)
Southern California Super Lawyers® | Intellectual Property (2017–2027)
Legal 500® | 2026–2027
Orange County Business Journal | Women in Law (2021)
Orange County Women Lawyers Association | Attorney of the Year (2024)
California Asian Pacific American Bar Association | President’s Award (2025)
At ILS, Tsang will lead the continued development of the firm’s Intellectual Property Practice Group, working alongside its commercial litigation, corporate transactions, regulatory compliance, and cross-border legal teams.
Her arrival further strengthens ILS’s ability to advise businesses on matters where intellectual property, commercial strategy, and complex legal risks intersect.
Beyond Growth: ILS Is Building the Next Generation of Global Law Firms
Tsang’s arrival represents more than the expansion of a single practice group. It reflects a deliberate investment in the future of ILS.
As businesses navigate increasingly complex legal, regulatory, and cross-border challenges, ILS is expanding its capabilities by bringing together attorneys with strong professional reputations, entrepreneurial instincts, and international perspectives.
But the firm’s ambitions go beyond headcount. ILS is building a platform where accomplished attorneys can grow their practices, collaborate across disciplines, and help shape the future of global legal services.
“We believe exceptional attorneys deserve more than the limitations of a traditional law firm model,” the ILS team stated. “That’s why we’re committed to offering highly competitive, above-market compensation opportunities, meaningful business development support, and the chance to help build something bigger. We’re not simply looking for attorneys to join a firm. We’re looking for partners who want to help define its future.”
This philosophy is driving ILS’s continued investment in talent, practice development, and cross-disciplinary collaboration.
By integrating expertise across commercial litigation, corporate transactions, intellectual property, employment law, and regulatory compliance, the firm aims to provide clients with sophisticated legal counsel grounded in commercial realities.
“We will never stop looking for exceptional talent, and we will never stop growing,” said Liu. “Mei’s arrival is an exciting milestone, but it is far from the finish line. Our vision is clear: bring together outstanding legal minds, build highly competitive practices, and establish ILS as a formidable force in the next generation of global legal services.”
A New Chapter. A Bigger Vision.
With Tsang leading its Intellectual Property Practice Group, ILS is expanding its capabilities in global IP portfolio management, intellectual property commercialization, strategic counseling, and complex IP litigation.
For businesses operating in the United States and international markets, her arrival means access to deeper intellectual property expertise backed by a multidisciplinary legal team that understands both legal risk and commercial opportunity.
For accomplished attorneys seeking a platform to build, lead, and grow, ILS is sending an equally clear message: The future of ILS is still being written. And we’re looking for the people who will help write it.
