Leydig, Voit & Mayer has always demonstrated an abiding commitment to provide clients with cutting-edge and business oriented intellectual property legal advice and services.

The firm has a history of distinguished courtroom performance. Leydig's attorneys have long been known for their success in both bench and jury trials for intellectual property right holders, and those accused of infringement or misappropriation. We have successfully litigated several industry-founding patents, including patents and patentees inducted into the National Inventors Hall of Fame.

In addition, the firm has represented many well-known patent applicants and brand owners in patent and trademark prosecution.

Litigation: The firm has been successful at litigating patent, trademark and other IP rights for over 100 years. We work closely with our clients to develop a strategic plan tailored to each client’s needs. Our clients trust our experience and reasoned opinions when faced with difficult decisions, and we work hand-in-hand with our clients in exploring all available options, and in assessing their potential risks, costs, and benefits to achieve their business objectives.

Patent Prosecution: We recognize that the patent is the most critical document in patent enforcement and valuation, and we work diligently to obtain the best possible protection for each of our clients’ inventions. Our attorneys and agents hold advanced technical degrees and have distinguished academic credentials. Many Leydig professionals have years of technical experience working in industry as well.

Trademarks and Copyright: Leydig’s attorneys assist our clients with name, mark and logo selection and registration; licensing of marks; and counseling in all areas, and handle all phases of trademark enforcement and litigation. In the copyright area, we advise corporate clients, content providers, distributors, and individual authors, artists, and entrepreneurs with respect to copyright protection and enforcement.

Post Grant Proceedings in the U.S. Patent and Trademark Office: Leydig has substantial experience in U.S. post grant proceedings including inter partes review, post grant review, covered business method review, interference, reexamination, supplemental examination, derivation proceeding, reissue, and in non-U.S. oppositions. Seasoned litigators who are registered to practice before the U.S. Patent Office and who possess technical and procedural knowledge help our clients navigate post grant proceedings and parallel litigations.

Intellectual Property Transactions: Leydig handles all types of IP transactions, including mergers, acquisitions, assignments, licenses, settlements, stock transfers, technology transfer agreements, research and development agreements, and more.

Trade Secrets and Unfair Competition: When trade secret misappropriation is threatened, companies can rely on our experienced attorneys to help them quickly seek judicial relief on an emergency basis or defend against such actions.
