July 07, 2022

Haynes and Boone, LLP and 15 of its partners from California, Colorado, Illinois, Texas and Washington, D.C., were recognized in the 2022 edition of the Intellectual Asset Management (IAM) Patent 1000 legal directory.

The publication recognized Haynes Boone among the top firms in the nation in various practice categories and among the leading firms in California, Illinois, and Texas. “Haynes Boone has filed more than 19,000 patent applications in the United States and abroad in the past five or so years and has honed its preparation and prosecution skills to a fine point while also cultivating exceptional strategic patent protection [experience],” IAM researchers said.

The following partners were also ranked among the top lawyers in patent prosecution, litigation, and transactions: Randall Brown, Tom Chen, Randall Colson, Russ Emerson, Ralph Gabric, Alan Herda, Lee Johnston, David McCombs, Greg Michelson, David O’Brien, David O’Dell, Ken Parker, Vincent Shier, Mark Tidwell and Jeff Wolfson.

The IAM Patent 1000 shines a spotlight on firms and individuals deemed outstanding in the patent practice. IAM interviewed more than 1,800 patent lawyers and in-house counsel over a five-month period to determine which firms and lawyers to include in the directory.

Below is a breakdown of rankings for the firm and partners, along with comments from researchers.


The firm ranked nationally in both Prosecution and Post-Grant Proceedings. Additionally, David McCombs was ranked nationally for Post-Grant Proceedings.


In Texas, Haynes Boone ranked among the Top 14 firms in Litigation; as “Highly Recommended” in prosecution – one of only four firms in the state to receive this ranking; and as one of eight “Recommended” firms for transactions work. Individual rankings include:

  • David McCombs and Russ Emerson (Litigation)
  • Randall Brown, Alan Herda, David McCombs, David O’Brien, David O’Dell and Mark Tidwell (Prosecution)
  • Randall Colson, David McCombs, David O’Dell and Mark Tidwell (Transactions)

Here is an excerpt of what researchers had to say:

“Haynes Boone litigates regularly in the Western and Eastern Districts of Texas and can be counted on for strategically savvy counsel and persuasive advocacy. Spearheading many of the most important campaigns, Russ Emerson is enthusiastically endorsed by his clients: ’Russ is brilliant at seeing the big picture and presents to juries in a compelling and respectful way – he understands how Texas juries think and prepares cases with that in mind. He also assembles excellent litigation teams.’”

Reviewers praised the volume and success rate of the firm’s Patent Trial and Appeal Board (PTAB) work, saying it’s: “a standout area of the practice. They have an excellent record to show for their efforts – check out the group’s 85% institution rate when acting for petitioners and near equal claim cancellation rate.”

Researchers added: “At the forefront of this dynamic practice are David O’Dell and David McCombs. Another lynchpin is David O’Brien. Turning to prosecution, the names to know are Alan Herda, Randall Brown, and Mark Tidwell. Herda chairs the firmwide IP group and sets the standard of excellence when it comes to strategic portfolio management and development. Taking the reins of the technology transactions practice, Randall Colson supplies vital licensing [experience].”


The firm is Recommended in Prosecution in California, with IAM calling out Tom Chen and Greg Michelson’s wide range and depth of skills and noting Ken Parker’s patent litigation skills adding value to the group.

Researchers stated: “The go-to’s for . . .. high-profile clients are Tom Chen and Greg Michelson, who sit in Orange County. They both have attributes that help them add value for their followers: Chen is appreciated for his advanced business knowledge and understanding of intellectual property in its commercial context. Michelson has a blend of counselling, portfolio management, litigation and licensing skills that help him see the big picture, identify risks and spot opportunities. In a notable development, the firm recently announced the return of Kenneth Parker, who brings trial seasoning to the San Francisco and Orange County offices.”


The firm is ranked in Litigation in Illinois, and Ralph Gabric is individually ranked.

Researchers stated: “Haynes Boone has come on in leaps and bounds in Chicago and built a compact but hard-hitting patent litigation unit in the city around Ralph Gabric ….” They also noted: “Eugene Goryunov has vast experience litigating at the PTAB. . . Haynes Boone is one of the most active outfits in the country representing petitioners at the PTAB.”


Lee Johnston was ranked individually in Litigation.
