Mark Harrison is chair of Venable’s Trademarks, Copyrights and Licensing Practice Group. One of the top trademark attorneys in the United States, he focuses on trademark, unfair competition, and copyright within intellectual property law, including the pharmaceutical industry. Mr. Harrison has handled trademark work for a global pharmaceutical company and a number of foreign pharmaceutical start-ups and domestic nutritional supplement companies.

Mr. Harrison has practiced in his field for over 30 years. He is a former Examining Attorney of the U.S. Patent and Trademark Office. He received awards for being in the top 20 filers of U.S. trademark applications for each of the years in 2002 through 2009, and is known as a top obtainer of registrations. Mr. Harrison has supervised the filing of trademark applications in virtually every country where such filings are possible, using his personally developed network of foreign associates. He is active in pro bono matters.

In Mr. Harrison’s focus area of trademarks, the group ranks highly in two benchmark annual reports: ninth in U.S. trademark applications filed (Trademark Insider, pub. 2010); and 12th in U.S. trademark registrations issued (Intellectual Property Today, pub. 2010). The group ranks 1st in Washington, DC, the third-busiest trademark market in the country, in both reports.

Increasing the value of your IP portfolio depends on a comprehensive and clearly thought-out strategy executed by attorneys with the broad experience and skills required to maximize opportunities and defeat challenges. We offer depth you won’t find in many general practice firms and breadth you won’t find at most IP boutiques. At Venable, you get the best of both worlds—a balance of aggressive and efficient litigation with strategic counseling savvy in all areas of IP that is the choice of leading companies here and abroad.

Led by former patent examiners and reinforced by attorney-scientists from a variety of technical disciplines, we have prepared and prosecuted tens of thousands of patents for U.S. and international clients.

We advise clients whose portfolios total in the tens of millions. In IP audits, we uncover hidden assets, evaluate new technologies, survey the competition for possible infringements and assess the patents of potential acquisitions.

We represent clients in patent, trademark, copyright, unfair competition, trade dress and domain name litigation in federal and state courts throughout the United States, as well as before the U.S. Court of Appeals for the Federal Circuit and the U.S. Supreme Court. An excellent case in point is where we successfully argued before the U.S. Supreme Court Wal Mart v. Samara Brothers, named the most important trade dress case litigated since 1998 (Legal Times, October 2002).

Today, Venable is an American Lawyer 100 law firm. With more than 675 attorneys across the country, we are strategically positioned to advance our clients’ business objectives in the U.S. and abroad. Our clients rely on Venable’s proven capabilities in all areas of corporate and business law, complex litigation, intellectual property, and regulatory and government affairs.

Our attorneys have an excellent understanding of their practice areas and bring a wealth of firsthand experience to the challenges and opportunities our clients face. In this era of ever-increasing scrutiny by the government, our clients benefit from Venable’s Washington know-how. Our attorneys, many of whom are former Members of Congress, regulators and senior government staffers, have the experience to provide solutions when government creates regulatory roadblocks.

“Mark Harrison acts on trademark, copyright and unfair competition issues, with clients noting that “his expertise in this area of law is impressive.” As well as having argued extensively before the Federal Circuit and the USPTO, he also possesses significant international experience.”
