We represent clients in the trial and appeal of disputes involving patents, trademarks, trade secrets, non-disclosure agreements, copyrights, antitrust, unfair competition and other business torts. We also assist our clients in procuring intellectual property rights and advise them on strategic use of intellectual property in their businesses.

We have a long track record of successfully representing a myriad of clients from diverse technologies on both sides of high-stakes intellectual property disputes in state and federal trial and appellate courts, at negotiating tables, at mediations, before the Patent and Trademark Trial and Appeal Boards and before arbitration tribunals.

Our clients run the gamut from multi-national corporations to individual innovators who come to us to enforce their rights and to defend against allegations of infringement on a variety of innovative and client-focused billing arrangements.


We are trial and appellate lawyers, not paper litigators. Each of our lawyers has a technical background. We are efficient, to the point and problem-solvers. We leverage our extensive intellectual property litigation experience to assist our clients to maximize the value of their intellectual property, evaluate their portfolios and engage in risk-benefit analysis when faced with threats of intellectual property litigation.

Before founding this law firm, the four founding partners had collectively practiced law for over 70 years at a well-known intellectual property trial law firm with a national reputation for its trial experience, success in high-stakes litigation and alternative fee representation. They litigated high-stakes and high-profile cases to verdicts, judgments and settlements and represented clients on technology transfer and licensing.


We are passionate about helping our clients navigate complex issues arising from innovation and intellectual property. The four founding partners formed this law firm with the vision of creating an intellectual property litigation law firm that is agile, selective and laser-focused on client interests. They built the firm with highly capable and trusted lawyers, technical consultants and support staff who are equally passionate about their work. We do what we do because we respect our clients, admire what our clients do and love doing what we do for our clients.
