Kearney, McWilliams & Davis: The San Antonio Patent Attorney Who Published Cancer Research Before Practicing Law

Before John J. Davis III was filing patent applications, he was co-authoring peer-reviewed cancer research — including a study on a novel delivery system for wild-type p53 and fiber-modified oncolytic adenoviruses in extremity sarcoma — as part of the Ph.D. in Virology and Gene Therapy he earned at the University of Texas MD Anderson Cancer Center before ever attending law school.

Origin and Background

Kearney, McWilliams & Davis, PLLC maintains a San Antonio office, confirmed through independent legal directory listings citing a San Antonio telephone number and through the firm’s own staffing, which includes a dedicated senior paralegal and office administrator based in San Antonio. John J. Davis III is a founder and Managing Member of the firm. He earned a Ph.D. in Virology and Gene Therapy from the University of Texas MD Anderson Cancer Center and UTHealth Houston Graduate School of Biomedical Sciences in 2006, and a Juris Doctor from South Texas College of Law. He is admitted before the U.S. Southern, Eastern, Northern, and Western Districts of Texas, the U.S. Court of International Trade, and the U.S. Tax Court.

Practice Concentration

Davis oversees the firm’s intellectual property, commercial property, commercial transactions, and litigation practice areas, with particular experience identifying and filing patent, trademark, and copyright protections for technology commercialization and enforcing those rights once secured. He also handles trademark filing, USPTO office action responses, oppositions, and licensing negotiations, and serves as counsel, mentor, or advisor to startup and accelerator programs. Kearney, McWilliams & Davis is a multi-practice firm with offices beyond San Antonio, and intellectual property is one of several practice areas alongside business and corporate law, real estate, and litigation. See this San Antonio Intellectual Property directory for how this Ph.D.-credentialed patent practice compares to dedicated IP boutiques and large-firm satellite offices also serving Bexar County.

Notable Work / Track Record

Davis’s pre-law scientific work is independently documented in the peer-reviewed research literature, including “Isolated limb perfusion: a novel delivery system for wild-type p53 and fiber-modified oncolytic adenoviruses to extremity sarcoma” and other published cancer virotherapy research co-authored during his graduate work. Awesome Attorneys did not identify a published table of his individual patent prosecution or litigation case outcomes, which is typical for a business-focused IP practice built on client relationships and technology commercialization work rather than published litigation results.

Client Voice

Awesome Attorneys did not identify a published set of itemized, attributed client reviews for Davis specifically across major consumer review platforms as of this profile’s research date, which is consistent with a practice built primarily on referral and institutional relationships with startups and accelerator programs rather than direct-to-consumer marketing.

Beyond the Courtroom

Davis serves as counsel, mentor, or advisor to companies and clients participating in several Texas startup, incubator, and accelerator programs. Awesome Attorneys did not independently verify the current, ongoing nature of each specific program relationship.

Recognition for This San Antonio IP Attorney

Awesome Attorneys did not identify Texas Board of Legal Specialization certification for John J. Davis 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 Ph.D. in Virology and Gene Therapy from a nationally recognized cancer research institution, combined with a peer-reviewed publication record predating his legal career — a scientific depth uncommon even among registered patent attorneys.

Texas Legal Backdrop

Patent prosecution proceeds under federal law before the USPTO rather than Texas state law, and biotechnology and pharmaceutical patents in particular, a natural fit given Davis’s virology and gene therapy background, are governed by specialized federal patentability standards for biological subject matter. Trademark filing and USPTO administrative proceedings, also part of his practice, likewise proceed under federal law rather than Texas state law. None of this is legal advice; a specific patent, trademark, or technology commercialization matter should be evaluated by a licensed attorney based on the actual facts involved.

Awesome Attorneys Assessment

John J. Davis III’s clearest differentiator is a genuinely rare combination: a Ph.D. in virology and gene therapy from a top cancer research institution, a pre-law record of peer-reviewed publication, and a current practice overseeing IP, commercial transactions, and litigation for a multi-office firm. The honest trade-off is that IP is one of several practice areas at a multi-practice firm rather than the firm’s sole focus, and Awesome Attorneys did not identify a published, itemized record of his individual case results or a broad base of consumer-style client reviews. For a San Antonio biotech, life sciences, or deep-tech startup that wants patent counsel with genuine, published scientific research credentials, that combination is a reasonable basis for a shortlist.
