Aeritas v. Panda Restaurant Group: Three Mixed-Mode Interaction Patents, Dismissed With Prejudice
Aeritas, LLC brought a patent infringement action in the Western District of Texas against Panda Restaurant Group and Panda Express, asserting three patents covering mixed-mode interaction technology. After 849 days of litigation, the parties jointly moved to dismiss — with all claims extinguished with prejudice and each side bearing its own costs.
A joint exit after 849 days: mixed-mode interaction claims extinguished
Aeritas, LLC filed suit on 3 October 2022 in the Western District of Texas (Waco Division) before Judge Alan D. Albright, asserting infringement of three patents — US7706819B2, US9888107B2, and US8055284B2 — against Panda Restaurant Group, Inc. and its subsidiary Panda Express, Inc. The asserted patents relate to mixed-mode interaction technology, broadly covering systems and methods for coordinating communication across multiple channels or modes in a networked environment.
On 29 January 2025 the court granted the parties’ Joint Motion to Dismiss. The order is precise in its asymmetry: all of Aeritas’s infringement claims were dismissed with prejudice, permanently barring refiling of those specific claims, while all counterclaims — presumably invalidity or non-infringement defences brought by the defendants — were dismissed without prejudice, leaving those defences potentially available in any future proceeding. Each party was taxed its own costs, consistent with a negotiated resolution rather than a litigated judgment.
At 849 days, the case exceeded the typical timeline for patent matters that resolve before trial in W.D. Texas, suggesting meaningful litigation activity — likely including claim construction briefing — before the parties reached resolution. The equal costs allocation and joint nature of the dismissal motion are consistent with a settlement or commercial arrangement, though the public record is silent on any financial terms. The with-prejudice dismissal of plaintiff’s claims effectively closes the door on Aeritas reasserting these patents against Panda entities on these grounds.

Joint dismissal with prejudice: what the asymmetric order means for both parties
With-prejudice dismissal bars Aeritas from refiling these claims
A dismissal with prejudice operates as a final adjudication on the merits, preventing the plaintiff from reasserting the same claims against the same defendants. Here, all of Aeritas’s infringement claims across all three patents are permanently extinguished as against Panda Restaurant Group and Panda Express. The joint motion framing indicates both sides agreed to this outcome, which is a hallmark of a negotiated resolution.
Claim preclusion appliesAeritas cannot refile: enforcement against Panda entities is closed
The with-prejudice dismissal of all claims means Aeritas has permanently relinquished its right to pursue infringement of US7706819B2, US9888107B2, and US8055285B2 against Panda Restaurant Group and Panda Express. Whether Aeritas received any consideration in exchange is not disclosed in the public record. The patents themselves remain in force and could theoretically be asserted against other defendants.
No refiling against Panda entitiesPanda Express exits cleanly; counterclaims preserved without prejudice
The defendants secured dismissal of all infringement claims with prejudice — eliminating the litigation risk from these three patents in this venue. Critically, their counterclaims (likely invalidity and/or non-infringement) were dismissed without prejudice, meaning those defences were not waived and could be raised in any hypothetical future proceeding. Each side bearing its own costs suggests neither party extracted a cost award concession.
Counterclaims preservedMixed-mode interaction patents remain active against other restaurant-tech operators
The resolution disposes of this specific dispute but does not invalidate the three asserted patents. Other restaurant chains, QSR operators, or technology vendors deploying mixed-mode interaction or omnichannel engagement systems should note that Aeritas retains enforcement rights against third parties. The resolution in W.D. Texas before Judge Albright — a venue historically active in patent matters — also suggests these patents survived without a validity ruling on the record.

Official order — verbatim text
The court’s order reflects a precisely structured bilateral agreement: Aeritas’s infringement claims are dismissed with prejudice — a final, claim-preclusive disposition — while the defendants’ counterclaims are dismissed without prejudice, leaving invalidity and non-infringement defences legally intact. The equal costs allocation is characteristic of a negotiated exit. No validity finding was made on any of the three asserted patents, meaning the patents’ enforceability against third parties is unaffected by this order.
US7706819B2, US9888107B2 & US8055285B2 — Mixed-Mode Interaction Technology
The three asserted patents — US7706819B2 (application no. 11/803848), US9888107B2 (application no. 15/206621), and US8055285B2 (application no. 11/928362) — relate to mixed-mode interaction technology. This domain broadly covers systems and methods that coordinate or transition user interactions across multiple communication modes or channels — for example, integrating mobile application, web, in-store kiosk, and voice-based interfaces within a unified platform. The application filing dates across the portfolio span multiple years, suggesting a continuation or family strategy by Aeritas to build layered protection across the technology.
For the quick-service restaurant sector, mixed-mode interaction technology is strategically central: QSR operators have invested heavily in omnichannel ordering systems that blend mobile apps, loyalty platforms, drive-through voice ordering, and in-store digital kiosks. Aeritas’s portfolio, if broadly construed, could read on common architectural patterns in these deployments. The fact that Panda Express — one of the largest QSR chains in the US — was targeted suggests Aeritas views high-volume, multi-channel operators as its primary enforcement targets. Other chains and their technology vendors should assess exposure before launching or scaling similar systems.
Should you run an FTO against US7706819B2, US9888107B2, and US8055285B2?
Any company developing or deploying omnichannel customer engagement systems — particularly those integrating mobile ordering, kiosk interaction, loyalty programmes, and voice or web channels — should treat this portfolio as a live FTO priority. The Panda resolution confirms Aeritas is an active enforcer; the with-prejudice dismissal provides no immunity to third parties. Restaurant technology vendors, POS platform providers, and QSR operators expanding digital ordering infrastructure are particularly exposed.

What this case signals for the restaurant tech and mixed-mode IP landscape
A with-prejudice exit in W.D. Texas without a cost award suggests a settlement. Three patents survive — and remain a risk for the wider QSR sector.
With-prejudice dismissal signals likely settlement, not litigation defeat
Joint motions to dismiss with prejudice — especially with symmetric cost allocation — are the standard procedural vehicle for patent settlements. Aeritas accepted permanent closure of its claims against Panda entities, consistent with receiving some form of commercial consideration. IP teams at other QSR operators should treat this as a licensing signal, not a validity clearance.
Three patents still active: FTO gap for QSR and omnichannel vendors
US7706819B2, US9888107B2, and US8055285B2 have not been invalidated and remain enforceable. Any company deploying mixed-mode interaction systems — coordinating app, kiosk, web, and voice channels — should conduct an FTO analysis against this portfolio before expanding product features. The Panda resolution does not provide third-party cover.
Aeritas v Panda — key questions answered
The with-prejudice dismissal of all of Aeritas’s infringement claims means those claims are permanently extinguished against Panda Restaurant Group and Panda Express. Aeritas cannot refile the same infringement claims based on US7706819B2, US9888107B2, or US8055285B2 against these defendants. The order does not affect Aeritas’s ability to enforce the patents against other parties.
This asymmetric structure is common in patent settlements. The defendants’ counterclaims — likely invalidity and non-infringement defences — were dismissed without prejudice to preserve their legal status without waiving them. This arrangement suggests the parties negotiated an exit where Aeritas accepted permanent closure of its claims, while the defendants retained their defences for any hypothetical future litigation scenario.
No. The joint dismissal order makes no finding on the validity or invalidity of US7706819B2, US9888107B2, or US8055285B2. The patents remain in force and enforceable against third parties. Only a formal invalidity ruling — from a district court, the PTAB, or an appellate court — would affect patent validity. Companies in the QSR and restaurant technology sector should not treat this dismissal as a validity clearance.
Mixed-mode interaction generally refers to systems and methods enabling users or operators to coordinate or transition between multiple communication or engagement channels — for example, mobile app, web interface, voice, and in-store kiosk — within a unified platform or session. In the QSR context, this is closely aligned with omnichannel ordering and loyalty systems. The precise claim scope of the three Aeritas patents would require review of the prosecution history and claim construction record.
