C. Dale Quisenberry: The Houston Patent Attorney Who Settled a Laser-Level Inventor’s Case Against the Country’s Largest Tool Makers

Origin and Background

Quisenberry Law PLLC is located at 13910 Champion Forest Drive, Suite 203, Houston, TX 77069, confirmed through State Bar of Texas records and the firm’s own site. C. Dale Quisenberry earned his undergraduate degree from the University of Missouri-Columbia and his J.D. from the University of Tulsa College of Law, and has practiced intellectual property law for more than 27 years. He is licensed in both Texas and Oklahoma, and is admitted to practice before the U.S. Court of Federal Claims, the Tenth Circuit Court of Appeals, the U.S. Court of Appeals for the Federal Circuit, the Northern District of Oklahoma, the Eastern and Southern Districts of Texas, and the USPTO.

Practice Concentration

Quisenberry’s practice covers patents, trademarks, copyrights, unfair competition, and trade secrets, with a genuine litigation and licensing component alongside prosecution work. The firm describes itself as “lean, nimble and efficient,” positioning itself as a smaller-firm alternative to the larger national IP practices in this category while still handling federal patent litigation. See this Houston Intellectual Property directory for how this solo litigation-and-prosecution practice compares to other Harris County firms.

Notable Work / Track Record

Quisenberry’s Martindale biography describes him obtaining a permanent injunction in a trademark and unfair competition lawsuit on behalf of a well-known Houston restaurant, and separately obtaining an injunction for an oil field client in a patent infringement matter in Texas federal court. A named client testimonial from a “Laser Level Inventor” describes Quisenberry handling patent infringement complaints and settlements against “the largest tool manufacturers in the United States,” stating every infringement case filed was resolved in the client’s favor. He has also successfully defended a Wyoming-based restaurant against a patent infringement claim in the Eastern District of Texas, and at the time of research was representing a photographer in multiple copyright infringement suits against more than 50 defendants across federal courts in Nevada, Delaware, Maryland, and Tennessee. These are client- and firm-reported case outcomes; a specific patent, trademark, or copyright matter’s result depends on its own facts.

Client Voice

Beyond the laser-level inventor testimonial above, multiple named reviewers describe Quisenberry’s work: one client calls him “the attorney you want when looking for a patent attorney,” another credits him with making a trademark and logo registration “incredibly easy,” and a third specifically praises his responsiveness during a time-sensitive trademark renewal. Quisenberry received Avvo’s Client’s Choice Award in 2021, a designation the platform states requires a significant volume of 4-plus-star reviews.

Recognition for This Houston Intellectual Property Firm

Quisenberry Law has received Lawyers.com’s Client Champion and Distinguished peer-review designations, based on the platform’s stated methodology combining client review volume and peer evaluation. Because patent attorneys are credentialed through USPTO registration rather than Texas Board of Legal Specialization certification, Awesome Attorneys notes this distinction rather than applying “specialist” language based on a state board credential that does not exist for this specialty; Quisenberry’s USPTO registration and 27-plus years of practice are the relevant credentials here.

Texas Legal Backdrop

Patent infringement litigation, a core part of Quisenberry’s practice, proceeds under federal law through federal district courts and, on appeal, the Federal Circuit, rather than Texas state statutes. Trademark and unfair competition claims, another documented specialty, blend the federal Lanham Act with Texas’s own unfair competition and trade-secret framework under the Texas Uniform Trade Secrets Act, Civil Practice & Remedies Code Chapter 134A. Copyright infringement claims, relevant to his photographer client’s multi-defendant litigation, proceed exclusively under federal copyright law regardless of the state where suit is filed. None of this is legal advice; a specific patent, trademark, or copyright matter should be evaluated by a licensed and USPTO-registered attorney based on the actual facts involved.

Awesome Attorneys Assessment

Quisenberry Law’s clearest differentiator is genuine litigation range packed into a solo practice: patent infringement injunctions, trademark and unfair competition wins, and active multi-defendant copyright litigation, all handled personally by a 27-year USPTO-registered attorney rather than delegated across a large associate bench. The honest trade-off is that this is a solo practice, meaning capacity is inherently smaller than the multi-attorney IP firms elsewhere in this category, and a client with a very large or technically complex patent portfolio may need a firm with a deeper bench. For an individual inventor or small business with a patent, trademark, or copyright matter who wants direct, personal attention from an experienced litigator at a stated affordable-rate structure, Quisenberry’s track record and strong client-review base are a reasonable basis for a shortlist.
