The Aguilera Law Firm: A San Antonio Patent Attorney Who Managed IP for an Entire University System Before Going Solo

Before Roman Aguilera III opened his own San Antonio practice, he spent years as Director of Intellectual Property for a major Texas university system, responsible for managing IP and commercialization across the university and its health science center — institutional-scale patent portfolio work that few solo San Antonio patent attorneys bring to a private practice.

Origin and Background

The Aguilera Law Firm PLLC’s principal office is in San Antonio, Texas, confirmed through the firm’s own website, which also lists the firm as serving Austin, Houston, and Dallas. Founder Roman Aguilera III earned a Bachelor of Science in Aerospace Engineering from the University of Texas at Austin in 1998 and a Juris Doctor from Texas Tech University in 2009, and is registered to practice before the United States Patent and Trademark Office. His pre-law career included project support work for NASA, software engineering at Valero Energy, consulting work for IBM, two years of nanoscale materials research at the University of Texas at Austin, and service as Director of Intellectual Property for a major university system overseeing IP and commercialization for the university and its health science center.

Practice Concentration

The firm is a dedicated intellectual property practice covering patents, trademarks, and copyrights for inventors, startups, and enterprises. Aguilera has combined patent filing and prosecution experience across more than three hundred applications spanning mechanical devices, software, hardware, nanotechnology, medical devices, biochemistry, vaccines, and the electrical arts — a technical breadth that reflects his multi-industry background rather than a single specialization. He also serves as a guest lecturer for undergraduate and graduate courses on the intersection of research, commercialization, and intellectual property. See this San Antonio Intellectual Property directory for how this multi-industry patent practice compares to litigation-focused boutiques and solo practices also serving Bexar County.

Notable Work / Track Record

Awesome Attorneys did not identify a published table of settlement or verdict figures for The Aguilera Law Firm, which is typical for a patent prosecution-focused practice rather than a litigation practice. What is independently verifiable is Aguilera’s volume of prosecution experience — over three hundred patent applications — and his prior institutional role directing IP and commercialization strategy for a university system, a scale of portfolio management distinct from most solo prosecution practices.

Client Voice

The firm carries a 4.5-out-of-5 rating across 17 reviews on one aggregator, with reviewers repeatedly praising Aguilera’s professionalism, ability to explain complex patent processes in plain language, and responsiveness, and several describing repeat engagements. Against that broadly positive record, Awesome Attorneys also identified one detailed negative review on Birdeye from a client alleging the firm charged over $10,000 for a series-LLC asset structuring matter it did not complete, and separately describing delays and a missed USPTO trademark-office follow-up on a design patent matter over a roughly two-year period. Awesome Attorneys did not independently verify either account and is disclosing the negative review directly rather than omitting it, alongside the firm’s otherwise consistently positive review record across Google, Lawyer.com, and other platforms reviewed.

Beyond the Courtroom

Aguilera’s guest lecturing on research commercialization and intellectual property at the undergraduate and graduate level is his most concrete documented form of service beyond direct client representation. Awesome Attorneys did not identify separate civic or nonprofit board service documented for him.

Recognition for This San Antonio IP Attorney

Awesome Attorneys did not identify Texas Board of Legal Specialization certification for Roman Aguilera III and does not apply “specialist” language on that basis — and separately notes that TBLS does not currently certify a distinct intellectual property specialty in Texas at all. His most concrete, independently verifiable credential is his USPTO patent attorney registration together with his prior directorship of intellectual property for a university system, an institutional role that required managing a technology transfer and patenting portfolio at scale.

Texas Legal Backdrop

Patent prosecution proceeds under federal law before the USPTO rather than Texas state law, making USPTO registration — distinct from Texas Bar licensure — the threshold qualification for the patent work that makes up the core of this practice. University and institutional IP commercialization, a documented part of Aguilera’s background, typically involves invention disclosure review, patentability assessment, and licensing negotiation under both federal patent law and the university’s own technology-transfer policies. None of this is legal advice; a specific patent, trademark, or business-structuring matter should be evaluated by a licensed attorney based on the actual facts involved.

Awesome Attorneys Assessment

The Aguilera Law Firm’s clearest differentiator is Roman Aguilera’s institutional-scale IP management background, from NASA project support through directing IP and commercialization for an entire university system, applied to a broad range of technical fields in a solo San Antonio practice. The honest trade-off is that alongside a strong overall review record, Awesome Attorneys identified one detailed, unverified negative account describing delays and communication gaps on a specific matter — a genuine caveat that a prospective client evaluating this firm should weigh against the volume of positive feedback and the firm’s technical credentials. For a San Antonio inventor who wants a patent attorney with institutional commercialization experience across a wide range of technologies, that combination, with the negative review noted, is a reasonable basis for a shortlist.

Methodology and Sourcing
