As a registered patent attorney and litigator, Daniel Valenzuela delivers problem-solving skills, legal strategies, and zealous advocacy to meet clients’ objectives. He focuses on complex patent litigation across the country and post-grant proceedings before the United States Patent and Trademark Office.

Daniel represents clients who work with a wide range of technologies, primarily in the telecommunications, automotive, LED, railcar, and gaming industries.  Specifically, he has worked with location tracking systems, “error-proof” fastening systems, remote checking technology, video conferencing over IP networks, angioplasty with shockwave technology, railcars, meltblown technology, power management software, Internet business methods, two-way radio communications over the Internet, personalized marketing technology, navigation and mapping systems, gaming technology, back lighting technology, optical switches, plant patents, solar-powered and color-changing lighting products, low profile LED light fixtures, and aircraft maintenance systems.

In his litigation experience, Daniel has taken the lead in motion practice, invalidity contentions, infringement contentions, claim constructions, discovery disputes, depositions, hearings, and trials. He has also represented multiple clients in reexaminations and inter partes reviews (IPRs), one in particular resulted in preparing an opposition brief to an appeal before the U.S. Supreme Court with a favorable outcome.

Further, Daniel has handled patent prosecution issues for smart card technology involving biometric authentication and other security features to prevent identity theft. He also has analyzed multiple patents relating to computer software and hardware for licenses and provided strategic direction on the protection of intellectual property for wireless communication systems and in-network security solutions.

Daniel has also taken the lead in representing several pro bono clients in federal and state courts, where he has obtained positive resolutions. This work included breach of contract cases where he served as first-chair trial attorney; taking multiple depositions while briefing and arguing motions in a Section 1983 civil rights action that resulted in a judgment of over $2 million in damages plus attorneys’ fees in excess of $1.9 million; and a federal appeal of a high school student’s right to a Free Appropriate Public Education under the Individual Disability Education Act.

Active in the community, Daniel has delivered IP presentations, volunteered for Career Day at elementary schools, and led panel discussions addressing diversity in the legal field.

Prior to private practice, he served as the law clerk and staff attorney to Judge Mike Herrera of the 383rd District Court in El Paso County, Texas.

While earning his electrical engineering degree, Daniel facilitated the design of a million-dollar project known as the Synchronous Optical Network (SONET) for the Texas Department of Transportation (TxDot) in El Paso, Texas.
