Intellectual Property Attorney Mark A. Tidwell Arrives at Haynes and Boone Houston Office


Mark A. Tidwell, an intellectual property attorney with experience in a wide array of matters from medical devices to oil field exploration tools, has joined the Haynes and Boone, LLP Houston office as partner.

“Mark’s arrival materially improves our capabilities and competitive position in the important area of intellectual property matters in the critical Houston market,” said Terry Conner, Haynes and Boone managing partner. “We are delighted to welcome an attorney of such stature to our growing IP practice.”

The addition of Mr. Tidwell is part of the firm’s long-term IP expansion plans, Mr. Conner said. Earlier this year, Haynes and Boone merged with the West Coast IP boutique, MacPherson, Kwok, Chen & Heid, LLP, a leading firm with offices in San Jose and Orange County, Calif. Since then, the firm has added several key lateral hires, including the former Chief IP Counsel for SiRF Technology, Nick Gikkas, and former Dell Vice President and Chief IP Legal Counsel Henry N. Garrana.

“Attracting talent like Mark Tidwell is an important component of our strategy to increase our reputation and business base in the technology sector,” said Randall Brown, chair of the firm’s Intellectual Property and Technology Transactions Section. “We are extremely pleased to have him on board.”

Mr. Tidwell comes to Haynes and Boone from the Houston office of Jackson Walker.

In more than 15 years of practice, Mr. Tidwell has focused on prosecution, acquisition, licensing, divestiture and enforcement of patent rights, trademark rights, trade secrets and copyrights. He has filed and prosecuted hundreds of patent, trademark and copyright applications.

The breadth of his experience is substantial. It includes medical and biomedical devices, nanotechnology, oil field exploration and production tools and equipment, data communications, power generation systems, heat transfer equipment, computer software and business methods, fuel cells and renewable energy systems, agricultural equipment, sports equipment, safety and security equipment, food preparation equipment, ultrasound equipment, seismic equipment, and ornamental designs, as well as other mechanical, electro-mechanical and chemical-mechanical devices.

His intellectual property litigation experience includes complex patent litigation involving patent infringement, patent invalidity, and technical aspects of patent prosecution procedures. He also handles trademark infringement, unfair competition, copyright infringement and breach of contract involving intellectual property.

Mr. Tidwell's technical background and experience in filing and prosecuting hundreds of patent, trademark and copyright applications provides clients with a significant advantage in intellectual property litigation disputes. He was formerly employed as a research and development engineer designing downhole oil field tools for Western Atlas International, Inc. in Houston, Texas.

Mr. Tidwell, who has been named as one of H Texas Magazine's "Houston Professionals on the Fast Track,” took his JD from South Texas College of Law in 1993 after graduating from Texas A&M University with a BS in mechanical engineering 1989.

He is a member of the American Bar Association, the Houston Bar Association, the Houston Intellectual Property Law Association and the American Intellectual Property Law Association. He is also an advisory council member for the Texas A&M Center for New Ventures and Entrepreneurship.
