Clifton McCann Joins DC Offices of Thompson Hine

Clifton McCann.

Thompson Hine LLP, a business law firm with offices Atlanta, Cincinnati, Cleveland, Columbus, Dayton, New York and Washington, D.C., recently announced Clifton McCann, who practices in the area of intellectual property dispute resolution, has joined the firm.

McCann, who is now a partner in the firm’s Intellectual Property group, joins Thompson Hine in the firm’s Washington, D.C. office, coming over to the firm from Venable LLP. The addition of McCann comes several months after several other recent additions of what the firm refers to as “top tier laterals.”

McCann, a patent attorney with more than 30 years of experience, focuses his practice on the development and defense of patent rights in the chemical, biological, mechanical and software/business method arts. His technical background is in chemistry, biotech and physics, and he is admitted to practice before the United States Patent & Trademark Office, in the District of Columbia and in the Commonwealth of Virginia.

McCann’s practice involves a full range of intellectual property services with an emphasis on litigation, which makes up about two-thirds of his practice.


Among his many successes are serving as lead trial counsel for patentee Ecolochem (now part of GE) in Ecolochem, Inc. v. Southern California Edison Co. This 10-year litigation, which included a three-week liability trial and week-long damages trial, resulted in a judgment of validity and willful infringement, with damages and $4 million in attorney fees awarded to the client. McCann successfully argued two related appeals to the U.S. Court of Appeals for the Federal Circuit, and the defendant’s petition for certiorari on the second appeal was denied. Edison paid Ecolochem an eight-figure amount in settlement at the conclusion of the damages trial.

“Thompson Hine’s intellectual property platform in Washington has a growing reputation,” said McCann of his decision to join the firm. “I am excited about the opportunity to join a fast-growing practice at a firm focused on client service and value. In addition, my clients will benefit from the additional resources of my new partners in areas such as venture capital, product liability litigation, international trade and government contracts.”

“We are pleased to welcome yet another top-notch lawyer to our Washington office. Last year we brought on John Ryan and Tom Haas as IP partner and as counsel, and we are excited about further expanding the group, strengthening our ability to provide a full range of IP services – from counseling to litigation.” said David A. Wilson, office partner-in-charge.

Earlier this year Thompson Hine moved it’s Washington, DC offices to new office space at 1919 M Street, N.W. after outgrowing its prior space. Many firms are either renegotiating leases or making moves, so that in and of itself is not necessarily unique. But moving and then on the heels of the move expanding with senior level, high caliber lateral hires suggests things are going well for the firm. It also suggests they are taking advantage of the economic downturn and position itself for what will hopefully become a full scale recovery at some point.
