Dynamic Data Innovations v. H-E-B: Dismissed With Prejudice After 217 Days
Dynamic Data Innovations LLC asserted US9632676B1 — a patent covering dynamic GUI data-object updates — against Texas grocery giant H-E-B, LP over its heb.com website and associated client-terminal software. The parties jointly stipulated to dismiss all claims with prejudice in under eight months, with each side bearing its own costs.
A rapid E.D. Texas exit: joint dismissal with prejudice signals resolution
On May 27, 2025, Dynamic Data Innovations LLC filed suit against H-E-B, LP in the Eastern District of Texas (Case No. 2:25-cv-00588) before Judge Rodney Gilstrap. The complaint alleged infringement of US9632676B1, a patent directed at dynamically updating sets of data objects through a graphical user interface on client terminals — technology the plaintiff contended was embodied in heb.com and its underlying hardware and software stack.
By December 30, 2025 — just 217 days after filing — the parties filed a Joint Stipulation of Dismissal under Rule 41 of the Federal Rules of Civil Procedure. Judge Gilstrap accepted the stipulation and dismissed all of Dynamic Data Innovations’ claims against H-E-B with prejudice. The with-prejudice designation is legally significant: it operates as a final adjudication on the merits, permanently barring Dynamic Data Innovations from reasserting the same patent claims against H-E-B on the same accused products.
The speed of resolution — under eight months in a district known for multi-year patent dockets — is consistent with a negotiated resolution reached before substantive motion practice concluded. The mutual cost-bearing arrangement suggests neither party extracted a clear litigation win, though the public record does not disclose any licensing terms, settlement payment, or covenant not to sue. What drove the parties to this outcome, and on what financial terms if any, remains confidential.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41 dismissal with prejudice — a permanent bar on refiling
A joint stipulation of dismissal under Rule 41(a)(1)(A)(ii) is a consensual procedural device. When entered with prejudice at the parties’ mutual agreement, it functions as a final judgment on the merits. Dynamic Data Innovations cannot bring the same US9632676B1 claims against H-E-B again in any federal court — the res judicata effect is binding and permanent.
Rule 41 — final on the meritsDynamic Data Innovations permanently relinquishes claims against H-E-B
By agreeing to a with-prejudice dismissal, Dynamic Data Innovations forfeits any future enforcement of US9632676B1 against H-E-B and the accused heb.com platform. The plaintiff retains the patent and may continue asserting it against other defendants, but H-E-B specifically is shielded from this patent going forward. The absence of a cost award against plaintiff is a minor concession from H-E-B’s perspective.
Claims extinguished vs. H-E-BH-E-B secures permanent protection from this patent assertion
For H-E-B, the with-prejudice dismissal provides durable legal certainty: heb.com and the accused dynamic-UI functionality can no longer be targeted under US9632676B1. The mutual cost-bearing arrangement avoided a fee-shifting battle under 35 U.S.C. § 285, which H-E-B might have pursued had it prevailed outright. The swift exit suggests H-E-B’s litigation team — Fish & Richardson — achieved a commercially acceptable outcome without protracted trial risk.
Permanent immunity from US9632676B1Dynamic GUI patent risk remains live for other e-commerce platforms
US9632676B1 survives this case and remains enforceable against other web and mobile commerce operators. Retailers with dynamically updating product-display interfaces — carousels, live inventory tiles, real-time cart updates — face potential exposure if Dynamic Data Innovations pursues further assertions. The rapid with-prejudice resolution against H-E-B does not signal invalidity; it signals a deal was reached before any merits ruling on the patent.

Official order — verbatim text
The court’s order accepting the joint stipulation is procedural rather than substantive — Judge Gilstrap made no finding on infringement, validity, or claim scope. The with-prejudice designation, however, carries real legal weight: it is treated as a judgment on the merits for res judicata purposes, permanently extinguishing Dynamic Data Innovations’ claims against H-E-B. The ‘each party bears its own costs’ instruction confirms no § 285 exceptional-case finding was sought or granted, which is consistent with a negotiated exit rather than a contested adjudication.
US9632676B1 — Dynamic data-object updates via graphical user interface
US9632676B1, issued from application US14/882679, protects a system and method for dynamically updating sets of data objects presented through a graphical user interface on client terminals — encompassing desktop computers, smartphones, and similar devices. The patent sits at the intersection of front-end web architecture and real-time data synchronization, covering functionality that is now pervasive in modern e-commerce: live product grids, dynamic cart updates, and real-time inventory displays rendered in a browser or app.
The strategic significance of this patent lies in its broad applicability to mainstream e-commerce infrastructure. Virtually every large-scale retail website — and many SaaS platforms — employs client-side dynamic data rendering of the type the patent describes. That makes US9632676B1 a potentially high-value assertion vehicle for a patent holding entity. The fact that the suit targeted heb.com, a major grocery e-commerce platform, suggests the patent holder views retail web interfaces as primary enforcement targets. Competitors and platform vendors should treat this patent as an active risk signal.
Should you run an FTO against US9632676B1?
Any company operating a consumer-facing website or mobile application that dynamically updates product listings, shopping cart contents, inventory status, or similar data-object sets should assess exposure to US9632676B1. This includes grocery and general retail e-commerce operators, marketplace platforms, and front-end UI framework developers. The heb.com accusation — targeting a standard product-display web interface — suggests the patent holder interprets the claims broadly enough to cover widely deployed UI patterns.
PatSnap Eureka’s FTO Search Agent can map the claims of US9632676B1 against your product’s technical architecture, identify relevant prior art that may affect claim validity, and surface the prosecution history file wrapper to reveal any claim-narrowing amendments. For e-commerce and retail-tech teams, running this analysis before litigation exposure arises is significantly cheaper than defending an E.D. Texas infringement action — even one that resolves pre-Markman.

What this case signals for the dynamic UI and e-commerce patent landscape
A swift with-prejudice exit in E.D. Texas before claim construction typically indicates a licensing resolution — or a decision to cut losses early.
E.D. Texas pre-Markman resolutions often reflect licensing economics, not merit
When cases before Judge Gilstrap resolve within eight months — before a Markman hearing — it consistently suggests the economics of licensing outweighed the cost and risk of trial. Defendants in this pattern either licensed quietly or achieved a covenant not to sue. For defendants watching similar NPE assertions, early engagement on claim scope can be decisive.
US9632676B1 remains a live enforcement risk for e-commerce UI developers
The with-prejudice dismissal does not invalidate the patent. Dynamic Data Innovations retains the ability to assert US9632676B1 against any other operator of dynamically-updating web or mobile GUIs. Retailers, SaaS platforms, and marketplace operators whose products update data objects client-side should assess their exposure now, not after a complaint is filed.
Dynamic v H-E-B — key questions answered
A with-prejudice dismissal under Rule 41 means all of Dynamic Data Innovations’ patent claims against H-E-B are permanently extinguished. The company cannot refile the same US9632676B1 claims against H-E-B or its heb.com platform in any federal court. The dismissal functions as a final judgment on the merits for res judicata purposes.
US9632676B1 covers systems and methods for dynamically updating sets of data objects through a graphical user interface on client terminals such as computers and smartphones. Dynamic Data Innovations alleged that heb.com’s product display, interactive features, and underlying software infrastructure embodied this patented technology — a claim pattern consistent with broad GUI dynamic-update assertions targeting retail e-commerce sites.
The case closed 217 days after filing, well before a typical Markman hearing in E.D. Texas. This timeline is consistent with a negotiated resolution — either a licensing agreement or a covenant not to sue — reached before expensive discovery and claim-construction briefing. The public record does not disclose financial terms, so the precise driver of the early resolution is unknown.
No. A joint stipulation of dismissal with prejudice carries no finding on patent validity or infringement. The patent remains in force and Dynamic Data Innovations retains the right to assert US9632676B1 against any other defendant. Companies operating dynamic-UI web or mobile products cannot rely on this case as precedent that the patent is invalid.
Judge Rodney Gilstrap of the Eastern District of Texas is one of the most experienced patent trial judges in the United States and presides over a disproportionately large share of U.S. patent litigation. His docket’s procedural efficiency and established patent local rules make E.D. Texas a strategically attractive venue for patent holders. Cases before Judge Gilstrap that resolve pre-Markman, as this one did, typically reflect economic settlements rather than judicial rulings on the merits.
