Tim St. Clair helps clients solve complex patent and other intellectual property problems with practical judgment shaped by unusual breadth of experience. Most patent lawyers are either litigators or prosecutors. Tim has built his practice doing both, along with substantial opinion work. That combination gives him a disciplined, real-world perspective on intellectual property: he helps clients focus on what matters, tune out patent lawyer noise, and address disputes and strategy questions with the right level of urgency, investment, and precision.
Tim’s practice spans patents, trademarks, copyrights, and trade secrets, with a particular focus on patent and trademark disputes, patent prosecution, freedom-to-operate analyses, infringement and validity issues, and intellectual property due diligence. Because he works across disputes, filings, and opinions, he brings a perspective that many IP lawyers do not. His litigation experience sharpens his counseling, and his prosecution and opinion work make him a more effective advocate when disputes arise. Clients rely on him not only to protect and enforce intellectual property rights but also to assess risk clearly, identify leverage, and develop practical strategies aligned with broader business objectives.
Clients also turn to Tim for courtroom credibility. He has handled dozens of patent and trademark cases, along with substantial copyright and trade secret disputes, in jurisdictions across the country. Before concentrating his practice in intellectual property, Tim spent the first 17 years of his career in insurance defense litigation, where he was regularly on his feet in courtrooms, tried jury cases, and learned to manage the competing pressures that shape real-world litigation strategy. That experience continues to influence how he practices today: with a clear eye for risk, efficiency, leverage, and commercial practicality. He is also often trusted by other lawyers to step into significant IP disputes when seasoned judgment is required.
In addition to litigation, Tim represents clients in building, protecting, and evaluating intellectual property portfolios in the United States and internationally. He advises on patent and trademark strategy, freedom-to-operate and infringement questions, and due diligence involving IP assets. His approach is grounded in clear communication, careful analysis, and practical recommendations appropriately sized to the problem at hand. Whether he is pursuing protection, evaluating exposure, or managing a dispute, Tim’s focus remains the same: helping clients make sound decisions that protect value, reduce unnecessary risk, and support long-term business goals.
As a certified mediator focused on intellectual property disputes, Tim brings practical credibility that comes from doing the work himself. He understands the legal issues, the realities of litigation, and the business pressures that often drive resolution. That perspective allows him to approach mediation not as an abstract process but as a practical effort to test positions realistically, narrow the true points of disagreement, and help parties reach sensible outcomes in difficult cases. His experience across litigation, prosecution, and opinion work also gives him a broader understanding of how IP disputes are evaluated from multiple angles, which can be especially valuable in resolving hard-fought disputes.
