Experience Counts in Intellectual Property


The Law Offices of Thaddius J. Carvis were established in 2003 in Leesburg, Virginia, a suburb of Washington, D.C., near the high technology corridor surrounding Dulles International Airport. Offices are now conveniently located in the ​District of Columbia and Ashburn, Virginia.

The founder, Thaddius J. Carvis, has 40 years of experience in intellectual property law and  began his career in the United States Patent & Trademark Office after graduating from the University of Wisconsin with a degree in Chemical Engineering.

Mr. Carvis was an examiner in chemical technologies in the U.S. Patent Office and served there as a law clerk to the Board of Appeals while attending law school in the evenings and graduating high in his class. He is a member of the Virginia and Patent Bars.

Mr. Carvis was a senior corporate attorney and partner in a well-established Connecticut law firm prior to returning to the Washington area and establishing the present firm.

While in Connecticut, he was president of the Connecticut Patent Law Association and worked with leading lawyers for over ten years putting together a popular and widely attended Joint Seminar produced by Connecticut and the New York, New Jersey and Philadelphia Intellectual Property Law Associations. He is currently the president of the Northern Virginia Patent Lawyers Club.

The firm specializes exclusively in intellectual property law, particularly concentrating in patents and trademarks, both in the United States and throughout the world. The firm maintains a full application and prosecution docket; actively participates in complex strategic and contested matters; analyzes, reviews, and prepares licenses and other technology transfer agreements in all aspects of intellectual property; and regularly analyzes patents and provides complete opinions relating to infringement, validity, overall patent strategy and related matters.

In the copyright realm, there is a growing need for struggling authors and artists to get the monetary rewards they deserve when their works are pirated. In most cases, contingent fee arrangements can be a good way to collect statutory and compensatory damages.

The firm's abilities extend worldwide due to an extensive network of associate attorneys developed over many years.
