Ameranth v. DoorDash: Five Restaurant-Tech Patents, One Venue Transfer
Ameranth, Inc. asserted five patents covering food-ordering APIs, menu integration, and fulfillment synchronization against DoorDash in W.D. Pennsylvania. After 797 days, Judge Hardy granted DoorDash’s motion to transfer, finding the Western District of Pennsylvania an improper venue and redirecting the case to the District of Delaware.
A venue battle resets the board on Ameranth’s DoorDash claims
Ameranth, Inc., a long-standing asserter of hospitality-technology patents, filed suit against DoorDash, Inc. on December 9, 2022, in the United States District Court for the Western District of Pennsylvania before Judge W. Scott Hardy. The complaint alleged infringement of five U.S. patents — US11205212, US11397981, US11276130, US11010819, and US11037254 — spanning fulfillment-service APIs, menu integration interfaces, order synchronization, and item-selection systems central to modern food-delivery platforms.
On February 13, 2025, the court granted in part DoorDash’s motion to dismiss or transfer for lack of venue, ordering the clerk to transfer the action forthwith to the United States District Court for the District of Delaware. Critically, the court made no ruling on the merits of infringement or validity. The transfer preserves all five patent claims, which will be re-litigated from the pleadings stage before a Delaware judge — a district with extensive patent-litigation expertise and a deep bench of prior Ameranth-related precedent.
The 797-day span before transfer suggests substantive briefing on venue was contested, consistent with DoorDash marshaling multiple law firms — Benesch, Greenberg Traurig, and Cozen O’Connor — to challenge Ameranth’s forum choice. The public record does not reveal whether settlement discussions occurred during this period. What remains unknown is how Delaware will treat any claim-construction or IPR history tied to these patent families, which may prove decisive for both parties once litigation resumes.

Case transferred to D. Delaware: what the venue ruling means for both parties
Venue transfer under 28 U.S.C. § 1406(a): what it means
A transfer for lack of venue means the originating court found it was not a proper forum — not that the plaintiff’s claims lack merit. Under 28 U.S.C. § 1406(a), rather than dismissing the case outright, the court redirected it to a district where venue is proper. All five patent claims survive intact; litigation simply restarts in Delaware. No infringement, invalidity, or damages ruling was made in Pennsylvania.
No merits adjudicationAmeranth retains its claims but loses its forum
Ameranth’s five-patent infringement action survives the transfer and will be refiled in the District of Delaware. However, losing the chosen forum is strategically costly: Delaware applies its own local patent rules, claim-construction schedule, and jury pool dynamics. Ameranth also absorbs the delay cost — over two years in Pennsylvania produced no substantive progress on the merits of its patent claims against DoorDash.
Claims preserved, forum lostDoorDash wins the venue fight, faces Delaware next
DoorDash secured a partial but meaningful victory by moving the case out of W.D. Pennsylvania — a district less familiar to it — into the District of Delaware, where DoorDash is incorporated and where courts have handled substantial patent dockets. Delaware’s predictable procedures and experienced patent bench may suit DoorDash’s litigation posture. The merits battle, however, remains entirely open.
Venue win, merits pendingFood-delivery API patents remain an active enforcement risk
The transfer signals that Ameranth’s patent portfolio covering fulfillment APIs, menu synchronization, and third-party ordering integrations remains viable and will continue to be enforced. For food-delivery platforms, aggregators, and restaurant-tech vendors integrating with third-party delivery services, the five asserted patents warrant FTO review. The District of Delaware’s robust patent docket means substantive rulings — including potential claim construction — could set precedent affecting the broader sector.

Official order — verbatim text
The court’s February 13, 2025 order granted DoorDash’s venue motion ‘in part,’ suggesting a full dismissal was denied in favor of transfer — preserving Ameranth’s claims rather than extinguishing them. The phrase ‘forthwith’ signals urgency in the transfer directive, consistent with a court that had made up its mind on venue well before issuing the order. Critically, the order is silent on infringement, validity, or claim construction, meaning neither party gained or lost any substantive legal ground on the merits of the five asserted patents.
US11205212 and four related patents — restaurant fulfillment and ordering APIs
The five asserted patents — US11205212, US11397981, US11276130, US11010819, and US11037254 — form a cluster covering the technical architecture of modern food-ordering and delivery platforms. Their subject matter spans APIs for third-party fulfillment services, real-time order synchronization, menu integration interfaces, and user-interaction-driven item selection. Application dates range across the mid-to-late 2010s, coinciding with the rapid commercialization of third-party delivery aggregators, suggesting these claims were drafted with platforms like DoorDash specifically in contemplation.
For restaurant-technology vendors, delivery aggregators, and hospitality SaaS providers, this patent family represents a meaningful enforcement risk. Ameranth has a documented history of asserting hospitality-tech patents against major industry players, and the five-patent cluster here covers functionality — API-based order routing, menu synchronization, fulfillment integration — that is nearly universal among modern food-delivery stacks. Companies building or licensing these capabilities should treat Ameranth’s portfolio as an active watch item, particularly as the Delaware case advances toward claim construction.
Should you run an FTO against US11205212 and the Ameranth cluster?
Any company operating a food-delivery platform, restaurant-management system, or third-party ordering integration that routes orders via APIs, synchronizes menus across channels, or connects restaurant POS systems to fulfillment networks should evaluate exposure to this five-patent family. The asserted patents are broad enough in scope to potentially capture common architectural patterns — not just DoorDash’s specific implementation. Given that the Delaware case will now proceed, a claim-construction ruling could define infringement scope for the entire industry.

What this transfer signals for food-delivery and restaurant-tech IP
Ameranth’s pivot to Delaware keeps five restaurant-API patents in play — and raises the stakes for every fulfillment-platform operator.
Venue selection is now a primary defense lever for tech platforms
DoorDash’s success in transferring this case out of W.D. Pennsylvania illustrates how venue challenges under TC Heartland can consume years of litigation before any merits ruling. Tech defendants facing opportunistic forum choices should assess §1400(b) arguments early and aggressively, particularly when incorporated in Delaware.
Ameranth’s five-patent cluster signals a broad enforcement strategy
Asserting five related patents covering APIs, menu integration, synchronization, and item selection suggests Ameranth is pursuing a portfolio — not a single-claim — enforcement approach. Any food-delivery or restaurant-tech operator that integrates third-party fulfillment services should treat each asserted patent as an independent validity and FTO risk.
Ameranth v DoorDash — key questions answered
Ameranth, Inc. filed a patent infringement action against DoorDash, Inc. in the Western District of Pennsylvania on December 9, 2022, asserting five patents covering food-ordering APIs and menu integration. On February 13, 2025, Judge W. Scott Hardy transferred the case to the District of Delaware after finding the Western District of Pennsylvania was not a proper venue. No ruling on the merits was issued.
Ameranth asserted five U.S. patents: US11205212B1 (fulfillment service APIs), US11397981B2 (information management and synchronous communications), US11276130B2 (integration of fulfillment functionality into third-party apps), US11010819B2 (item selection based on user interactions), and US11037254B1 (universal menu integration interface). Together they cover core architectural features of food-delivery and restaurant-ordering platforms.
The court granted DoorDash’s motion to dismiss or transfer for lack of venue under 28 U.S.C. § 1406(a), finding that the Western District of Pennsylvania was not an appropriate venue for the action. Rather than dismissing the case outright, the court ordered it transferred to the District of Delaware, where DoorDash is incorporated, preserving Ameranth’s claims for adjudication there.
No. The February 13, 2025 order addressed only venue. The court made no findings on patent infringement, claim validity, or damages. All five patent claims survive and will be litigated on the merits in the District of Delaware, where the case has been transferred.
The transfer means Ameranth’s five-patent infringement action against DoorDash continues in the District of Delaware — a jurisdiction with deep patent-litigation expertise and a large docket of technology cases. Ameranth retains all its claims but loses its chosen forum. Delaware’s claim-construction outcomes could set persuasive precedent affecting other food-delivery and restaurant-tech operators facing similar API and menu-integration patent claims.
