My practice is in the area of intellectual property law, with an emphasis on litigation, including contingent fee patent infringement lawsuits. I also have experience in mediation, prosecuting patent and trademark applications before the United States Patent and Trademark Office, rendering infringement and validity opinions, licensing and technology transfer, and client counseling.

I have experience in litigating a broad array of intellectual property cases including patent, trademark, copyright, trade dress, unfair competition, and related common law and state causes of actions. I also have experience in a wide variety of technologies, ranging from oil field equipment, medical devices, computer accessories, health care systems, and software inventions, to name a few.

In addition to representing both plaintiffs and defendants on an hourly basis, a portion of my practice also includes litigating patent cases on a contingency basis.  We are flexible in negotiating contingent-fee and alternative billing arrangements, with the range of rates depending on the nature of the case.  The fee can also be based upon a mixed hourly/partial contingent fee arrangement.  Our standard agreement provides that the client will owe no attorneys' fees unless a recovery is obtained, but regardless of any recovery the client will be responsible for a portion (to be agreed on) of court costs and litigation expenses as they are incurred.  The balance of costs and expenses will be paid from the client's share of any recovery.

Not Certified by the Texas Board of Legal Specialization.  No designation has been made by the Texas Board of Legal Specialization for a Certificate of Special Competence in the area of intellectual property law.
