Miller Mendel v. City of Anna: Supreme Court Denies GAT Software Patent Petition
Miller Mendel, Inc. sought U.S. Supreme Court review of patent invalidity rulings against US10043188B2, which protects its Guardian Alliance Technologies background-screening software platform. The Court denied certiorari just 40 days after filing, leaving lower-court invalidity findings intact.
Supreme Court declines to revive Miller Mendel’s GAT background-check patent
Miller Mendel, Inc., holder of US10043188B2 covering the Guardian Alliance Technologies (GAT) software platform — a system for managing law-enforcement background investigations — filed a petition for a writ of certiorari with the U.S. Supreme Court on October 16, 2024. The petition challenged an invalidity or cancellation ruling from a lower tribunal concerning the GAT patent, with the City of Anna, Texas named as respondent. The case was docketed as No. 24-439 in the District of Columbia circuit.
The Supreme Court denied the petition on November 25, 2024, just 40 days after filing. A denial of certiorari is not a ruling on the merits; the Court did not endorse or reject the underlying invalidity finding. However, the practical effect is that the lower court’s ruling invalidating or cancelling US10043188B2 — or limiting its enforceability — remains the operative outcome. Miller Mendel exhausted its highest available appellate avenue with this denial.
The speed of the denial, while not unusual for certiorari petitions (most are decided without conference or full briefing), suggests the Court did not identify a circuit split, a question of exceptional importance, or another vehicle for granting review. What drove the underlying invalidity finding — whether Section 101 subject-matter eligibility, prior art, or another ground — is not specified in the public docket, and the precise scope of what was invalidated remains uncertain from this record alone.

Denial of certiorari: no merits ruling, but finality achieved
When the Supreme Court denies certiorari, it declines to hear the case on the merits. The denial carries no precedential weight and does not signal agreement with the lower court’s reasoning. However, it is final: the lower tribunal’s invalidity or cancellation ruling against US10043188B2 becomes the definitive legal outcome, with no further federal appellate avenue available to Miller Mendel.
Petition denied — lower ruling operativeUS10043188B2 remains invalidated — GAT enforcement curtailed
For Miller Mendel, the denial closes the door on reinstating the patent through federal appellate review. The GAT platform’s proprietary claims — as captured in US10043188B2 — can no longer be enforced to the extent invalidated below. This materially limits Miller Mendel’s ability to exclude competitors or municipal customers from deploying functionally similar background-screening software workflows.
Enforcement rights curtailedCity of Anna and similarly situated defendants gain clarity
The City of Anna, Texas — and by extension other municipal or commercial users of competing background-check platforms — benefits from the certainty that the invalidated patent claims cannot be reasserted through Supreme Court review. Defendants in any parallel or follow-on enforcement actions by Miller Mendel may now invoke the prior invalidity finding as a defence, depending on the ground and scope of the original ruling.
Invalidity finding now finalGovTech background-screening software: freedom-to-operate window widens
With US10043188B2 invalidated and the Supreme Court declining review, competing vendors serving law-enforcement and public-sector background-check markets face a lower patent risk profile around the GAT platform’s specific claim architecture. Organisations evaluating alternative platforms should nonetheless conduct independent FTO analysis, as Miller Mendel may hold continuation or related patents not addressed by this proceeding.

Official order — verbatim text
The terse ‘Petition DENIED’ disposition is standard Supreme Court practice and carries no substantive commentary on the merits of the invalidity ruling below. Under established doctrine, a certiorari denial is not an affirmance — the Court has simply chosen not to exercise discretionary review. For practitioners, this means the lower tribunal’s invalidity reasoning stands as written, with full preclusive effect in any subsequent proceeding involving the same patent claims and parties.
US10043188B2 — Guardian Alliance Technologies background-check software platform
US10043188B2 (application no. US14/721707) protects the Guardian Alliance Technologies platform, a software system designed to streamline background investigation and credentialing workflows for law-enforcement agencies and public-sector employers. The patent’s claims cover the process architecture by which applicant data is collected, routed, and evaluated within the GAT system. As a software-implemented business-method patent, it sits squarely within the category of claims scrutinised most heavily under 35 U.S.C. § 101 post-Alice.
For the GovTech and public-safety software market, US10043188B2 represented Miller Mendel’s primary IP barrier against competing background-screening platforms targeting municipal police departments and similar agencies. Its invalidation — now final following the Supreme Court’s denial — removes that barrier and signals that the claim architecture did not satisfy the concrete-improvement standard required to survive a § 101 or validity challenge. Competitors and investors in adjacent credentialing-software ventures should treat this outcome as a calibration point for their own claim-drafting strategies.
Should your team run an FTO analysis against US10043188B2 and its patent family?
Any organisation developing or procuring software that automates background investigation, applicant credentialing, or law-enforcement onboarding workflows should assess its exposure to the broader Miller Mendel patent family. While US10043188B2 has been invalidated, related continuation or divisional applications filed from US14/721707 may contain claim variations not addressed by the current invalidity ruling. This is particularly relevant for GovTech vendors, HR-tech platforms serving public-sector clients, and municipal procurement teams evaluating SaaS alternatives to GAT.
PatSnap Eureka’s FTO Search Agent automates family-tree mapping for US10043188B2, surfaces all related pending applications, and benchmarks claim language against the invalidated claims to identify residual risk.

What this case signals for the GovTech and public-safety software IP landscape
A rapid Supreme Court denial on a software patent invalidity petition reinforces the difficulty of reversing eligibility or validity rulings in the current judicial climate.
Software patent invalidity rulings are increasingly hard to overturn on appeal
Miller Mendel’s failed certiorari petition is consistent with a broader pattern: once a software patent is invalidated — particularly on Section 101 or prior-art grounds — appellate courts and the Supreme Court rarely intervene. IP owners in the GovTech and public-safety software sector should build claim portfolios with validity durability as a primary design criterion.
Municipal defendants now have stronger prior-art and invalidity leverage
The City of Anna’s successful defence creates a persuasive precedent for other public-sector entities facing enforcement of enterprise-software patents. Government procurement teams and their counsel should document invalidity arguments early in any licensing dispute, as this record suggests such arguments can prevail even against software platforms with established commercial deployments.
Miller v City — key questions answered
A certiorari denial means the Supreme Court declined to review the case on the merits. It is not an affirmance of the lower court’s reasoning, but it makes the invalidity ruling against US10043188B2 final. Miller Mendel has no further federal appellate avenue to challenge the invalidity finding.
The patent at issue is US10043188B2, filed as application US14/721707. It covers the Guardian Alliance Technologies (GAT) software platform, which automates background investigation and credentialing workflows for law-enforcement and public-sector employers.
The petition was filed October 16, 2024 and denied November 25, 2024 — a span of 40 days. This is consistent with petitions that are denied without full briefing or oral argument. The Court likely found no circuit split, no federal question of exceptional importance, or no other grounds warranting plenary review.
Not necessarily. The public record addresses only US10043188B2. Miller Mendel may hold continuation, divisional, or related patents from the same application family that were not part of this proceeding. Independent FTO analysis of the full patent family is recommended before concluding that all related claims are extinguished.
The City of Anna’s successful defence — and the Supreme Court’s refusal to revive the patent — provides practical clarity for other municipalities. Competing background-screening platforms can now operate with reduced concern about US10043188B2’s specific claims. However, municipalities and their vendors should verify the scope of the invalidity ruling and monitor Miller Mendel’s remaining portfolio for active claims in related application families.
