Omnus Law & 52 Launch

Peter D. Weinstein is a Partner and Practice Chair of Intellectual Property at Omnus Law, with nearly 30 years of experience in intellectual property, complex litigation, and strategic counseling for technology-driven companies. A scientist-turned-lawyer with a PhD in Biology/Immunology, Dr. Weinstein brings a rare combination of deep technical fluency, global research experience, and high-stakes legal judgment to the innovators and organizations he serves.

A U.S.-registered patent attorney, Dr. Weinstein began his legal career at leading international law firms before serving as Senior Patent Counsel at Baxter Healthcare Corporation, where he led IP strategy, played a key role for business development, led two of the companies major licensing and technology transfer efforts and led IP litigation for major global therapeutics. While at Baxter, Dr. Weinstein was also an active member of two research core teams based in Europe that brought two therapeutics from the bench to the market (Adenovate© and VonVendi©). During his tenure, he built patent portfolios that have since generated significant monetary value and helped shape international research and development initiatives.

As Practice Chair of Intellectual Property at Omnus Law, Dr. Weinstein leads the firm’s IP strategy and growth. He works closely with partners, associates and other team members to build a forward-looking platform serving biotechnology, pharmaceutical, medical device, artificial intelligence, energy, hardware/software and advanced engineering clients. His practice focuses on patent prosecution, patent litigation, portfolio development, technology commercialization, corporate, employment and advising emerging and high-growth companies across complex technical sectors.

Dr. Weinstein’s experience extends beyond traditional legal roles. As a co-founder and CEO of a rapidly scaling biotechnology company, Circurna, he has personally built and led teams, navigated fundraising, overseen clinical research efforts to bring multiple therapeutics to the clinic, and negotiated global partnerships. This operator perspective allows him to advise clients not only as legal counsel, but as a strategic business partner who understands how intellectual property, regulatory timelines, investment strategy, corporate, employment, partnering and commercial viability intersect.

His international background includes scientific research in Taiwan and business and legal work in Austria, collaborations with institutions across Europe, Asia, and South America, and coordination of cross-border patent portfolios and litigation with foreign counsel. Clients rely on Dr. Weinstein for clarity, responsiveness, and the ability to translate complex science into strong, defensible, and commercially meaningful intellectual property assets.

Today, Dr. Weinstein partners with innovators, founders, research teams, and established companies to develop IP strategies that support growth, investment, and market differentiation. Known for his technical depth, strategic thinking, and results-driven leadership, he continues to build a practice defined by client trust, word-of-mouth referrals, and long-term relationships.
