About Charles
Biography
For over twenty years it has been my true honor and privilege to worke with cutting edge growing companies across the United States, in business and intellectual property law matters. In the past five years, my Firm and I have saved and recovered in excess of $2.3 billion for our clients in federal and state courthouses across the country.
I am dual Board Certified in Civil Trial Law and Consumer and Commercial Law by the Texas Board of Legal Specialization, and am AV Preeminent rated by Martindale Hubbell - the highest rating an attorney may receive. I am licensed in both Texas and California, and have expanded my practice throughout the southwest U.S.
I have authored law review articles and parts of legal textbooks on topics ranging from intellectual property licensing, international letters of credit and the role of insurance defense counsel in complex litigation matters, and Implied Licenses in Copyrights.
My cases typically involve representing businesses in complex business transactions, partnership (and shareholder) disputes, executive employment litigation, Non-Compete and Non-Disclosure Agreements, and intellectual property law matters (copyrights, trademarks, trade secrets).
I have served as lead trial counsel in complex litigation matters involving Shell Oil Company, Ralph Parsons Engineering, Union Oil of California, Sentinel Integrity Solutions, Global Check Services, Mossberg Shotguns, and the Stanford Financial Group, in lawsuit filed in federal and state courts in Texas, California, Colorado and Florida.
I look forward to speaking with you about your legal needs.

Non-trustworthy
I retained this firm (Charles Vethan) during active litigation under a contingency arrangement. In the middle of the case, Charles withdrew. Shortly after withdrawing, Charles initiated litigation against me seeking substantial attorney’s fees, including enforcement of a contingency fee I dispute ...

Outstanding Trial Lawyers
Team Vethan took my case to a jury and delivered. Not the cheapest guys in town, but worth every penny. If I could give them 10 stars, I would.

Great Lawyer, Highly Recommend
The Vethan Law Firm represented me in a stressful Lawsuit involving my former business partners. The attorneys at VLF were professional and, I felt, were personally vested in protecting my interests. Through their diligent efforts they saved my business.

Thank You!
We can't thank you and your team enough, Charles. We left our old law firm in the middle of litigation that didn't seem was helping us. Once your team took over, everything changed. There is no way we could gotten rid of the case without you guys.
