Philip G. Hampton, II

Phil Hampton is Administrative Partner of the Washington, D.C. office of Haynes and Boone, LLP and a partner in the Intellectual Property Litigation Practice Group. Phil has more than 30 years of experience practicing intellectual property law as both a practitioner and an administrator, with a focus on patent and trademark litigation, patent and trademark counseling, trademark prosecution, and counseling with regard to the intellectual property aspects of the Internet. As corporations and individuals continue to extract value from their intellectual property, Phil has expanded his practice to include licensing and merchandising agreements based on patents, trademarks, trade secrets, and copyrights. He also has negotiated the transfer of intellectual property and prepared documents pursuant to corporate acquisitions.

From 1994 until 1998, Phil was the Assistant Commissioner for Trademarks at the USPTO. In that position, he had overall responsibility for trademark operations, and focused on restructuring the trademark registration process and improving the policies of the USPTO to align them more closely with the needs of its customers. He also testified before Congress and represented the United States at diplomatic conferences and international meetings. As a member of the executive staff of the USPTO, Phil provided senior level input on proposed changes to the Patent Act, the USPTO rules of practice, and the Manual of Patent Examining Practice.

With the exception of the nearly five years that he served as an Assistant Commissioner at the U.S. Patent and Trademark Office (USPTO), Phil has practiced continuously in both patent and trademark law. He has been an expert witness in several trademark infringement actions, and also has served as a Special Master in patent infringement actions for the U.S. District Court for the District of Maryland. Phil is AV® Peer Review Rated Preeminent by Martindale-Hubbell® Law Directory.  In addition to his law degree, Phil holds an S.M and an S.B. in chemical engineering. Phil's areas of concentration include:

Intellectual Property Litigation

Phil has been involved in all aspects of patent and trademark litigation in U.S. District Courts, mini-trials, ITC Section 337 hearings, and Trademark Trial and Appeal Board opposition and cancellation proceedings. While not afraid to litigate, Phil tries to find cost effective means to resolve disputes. For example, he recently convinced a district court judge to vacate the judge's published summary judgment decision and allow the parties in a patent infringement action to settle their patent dispute in the interest of judicial economy.


Phil was the Assistant Commissioner for Trademarks for nearly five years. As CEO of the trademark operations in the United States, he oversaw the reengineering of the USPTO. He also promulgated almost 200 Commissioner’s Decisions and oversaw the first new edition of the Manual of Trademark Examining Procedure in almost ten years. In the years before and after his service at the USPTO, Phil prepared, filed, and prosecuted hundreds of U.S. and foreign trademark applications and prepared scores of trademark opinion letters. He also has prepared and filed appeals to the Trademark Trial and Appeal Board and conducted oppositions and cancellations.

Patent Prosecution and Counseling

Phil has prepared, filed, and prosecuted U.S. and foreign patent applications. He has prepared opinions regarding patentability, validity, and infringement issues, and participated in appeals before the Board of Patent Appeals and Interferences. He also has conducted interviews of examiners, SPEs, and technical center directors at the USPTO. Because of his knowledge of the people and processes of the USPTO, Phil has conducted investigations of “atypical” prosecutions of patent applications within the USPTO.
