David A. Chavous concentrates on intellectual property litigation. With 15 years of experience in patent law, Dr. Chavous enforces the patent rights of his clients and defends his clients against assertions of patent infringement. He seeks to obtain the best resolution of a case for his clients, through negotiated settlement or by achieving favorable verdicts for his clients at trial. Dr. Chavous’s litigation practice also includes representing clients in trade secret, copyright, trademark, and IP ownership matters. He has represented clients in both state and federal courts in most jurisdictions across the country.

Dr. Chavous also represent clients in the procurement of patents, copyrights, and trademarks, obtaining hundreds of patents, as well as hundreds of trademarks and copyrights, for his clients. His litigation experience informs his intellectual portfolio development strategy so that he can advise clients on smart strategies to obtain and strengthen their intellectual property portfolios. In addition, Dr. Chavous provides legal opinions on the validity of patents, freedom-to-operate for businesses seeking to enter a market space, and the risks associated with IP on a business’ activities. He provides his clients the legal basis for his opinions, how to proceed, and a plan of action if claims are asserted against a client.

Lastly, Dr. Chavous also offers intellectual property audits to identify the weak points in an intellectual property portfolio. Based on his experience litigating intellectual property rights and defending against infringement claims, he analyzes clients’ portfolios to determine potential issues that may devalue their IP position.

Dr. Chavous is a member of the Massachusetts Bar, the United States Patent and Trademark Office bar, and the District of Massachusetts.
