Hanshow America v. SES-Imagotag: Federal Circuit Appeal Voluntarily Dismissed in 12 Days
Hanshow America, Inc. brought a patentability challenge against SES-Imagotag, Inc. at the Federal Circuit over US10674340B2, a patent covering systems and methods for communicating spatially organized information. The parties agreed to dismiss the appeal under Fed. R. App. P. 42(b) just 12 days after filing, with each side bearing its own costs.
A 12-Day Federal Circuit Appeal That Ended Before It Began
On 22 May 2025, Hanshow America, Inc. filed Case No. 25-1806 at the U.S. Court of Appeals for the Federal Circuit, challenging the patentability of US10674340B2 — a patent held by SES-Imagotag, Inc. covering a system and method for communicating spatially organized information. The underlying dispute falls within the invalidity/cancellation action category, suggesting the appeal likely arose from a Patent Trial and Appeal Board proceeding or related administrative challenge. Hanshow was represented by Arch & Lake LLP, while SES-Imagotag retained Perkins Coie LLP.
Just 12 days after filing, on 3 June 2025, the Federal Circuit ordered the proceeding dismissed pursuant to Fed. R. App. P. 42(b), which governs voluntary dismissals agreed to by the parties. The order specifies that each side shall bear its own costs. Critically, the dismissal order does not specify whether the dismissal is with or without prejudice — the public record is silent on this point, leaving open questions about Hanshow’s ability to re-pursue the invalidity challenge through other available channels.
A resolution of this speed — 12 days from filing to dismissal — is highly atypical for Federal Circuit appeals and strongly suggests the parties reached a private arrangement, whether a settlement, licensing agreement, or strategic decision to withdraw, before any substantive appellate activity occurred. The mutual cost-bearing arrangement is consistent with a negotiated resolution rather than a unilateral capitulation. What drove this rapid conclusion, and whether Hanshow retains any avenue to challenge the patent’s validity, remains unknown from the public record.

12 days — resolved before substantive briefing could begin at appellate level
Voluntarily dismissed: what the agreed order means for both parties
Fed. R. App. P. 42(b): a party-agreed appellate exit
Rule 42(b) of the Federal Rules of Appellate Procedure allows parties to voluntarily dismiss an appeal by filing a signed agreement. Unlike a court-ordered dismissal on the merits, this mechanism requires mutual consent and carries no appellate court judgment on the underlying patent validity questions. The Federal Circuit’s order here reflects that agreement — the court did not rule on patentability.
No merits ruling issuedThe public record is silent on prejudice terms
A voluntary dismissal ‘with prejudice’ bars the appellant from re-filing the same challenge; ‘without prejudice’ preserves that right. The Federal Circuit’s order in this case does not specify either. This distinction is commercially significant: if dismissed without prejudice, Hanshow may retain options to re-challenge US10674340B2’s validity through IPR or other proceedings. The public record does not resolve this question.
Prejudice terms undisclosedHanshow exits the appeal with no appellate ruling on validity
Hanshow America secured no Federal Circuit finding of invalidity. Whether this reflects a settlement, a licensing agreement, or a strategic decision to abandon the appeal is not disclosed in the public record. The speed of the dismissal — 12 days — suggests the decision was reached before any substantive briefing. Hanshow’s future litigation posture against this patent remains uncertain.
No validity ruling for challengerUS10674340B2 survives this challenge intact
SES-Imagotag’s patent emerges from this proceeding unchallenged at the appellate level. No court has ruled on the merits of the invalidity claims brought by Hanshow. The patent’s enforceability is unaffected by this dismissal, and SES-Imagotag can continue to assert or license US10674340B2 in the electronic shelf label and retail IoT space. The cost-neutral order limits any financial exposure from this appeal.

Official order — verbatim text
The Federal Circuit’s order is purely procedural — it reflects the parties’ mutual agreement under Fed. R. App. P. 42(b) and carries no substantive ruling on the patentability of US10674340B2. The absence of a prejudice designation in the order is legally significant: without an explicit ‘with prejudice’ finding, future invalidity challenges through PTAB or other fora may remain available. The cost-neutral disposition suggests a negotiated resolution rather than a default or abandonment.
US10674340B2 — Spatially Organised Wireless Communication System
US10674340B2 protects a system and method for communicating spatially organized information — a technology class central to electronic shelf label (ESL) and retail IoT infrastructure. The patent, filed under application number US16/281190, covers the coordination and transmission of location-aware data across wireless networks, enabling dynamic price and product information display at retail fixtures. This technology domain sits at the intersection of wireless communication protocols, spatial data management, and retail automation.
In the competitive ESL market, patents covering core communication architectures carry significant strategic weight. SES-Imagotag is a leading global ESL supplier, and US10674340B2 represents a potentially foundational asset in its IP portfolio. Hanshow America, a direct competitor in the same market, initiated a validity challenge — consistent with a competitive strategy to neutralise blocking patents. The patent’s survival of this appeal, without any merits ruling, means it remains a live risk for any ESL or smart retail competitor operating in spatially-aware wireless communication systems.
Should you run an FTO analysis against US10674340B2?
Any R&D team or product organisation developing electronic shelf label systems, retail IoT platforms, or spatially-aware wireless communication infrastructure should assess their exposure to US10674340B2. The patent’s validity was challenged but never adjudicated — meaning it carries full presumption of validity. If your product transmits spatially organised information to shelf-edge or retail display devices, this patent warrants a formal freedom-to-operate review.
PatSnap Eureka’s FTO Search Agent can map your product’s technical features against the claim scope of US10674340B2, surface prior art that was or was not considered during prosecution, and identify design-around opportunities. Given the unresolved prejudice question in this dismissal, ongoing monitoring for new PTAB filings or continuation patents from SES-Imagotag is also advisable for any market participant in the ESL or smart retail space.

What this case signals for the electronic shelf label IP landscape
A 12-day Federal Circuit exit in a patentability dispute points to private deal-making — and raises questions about the ESL patent battleground.
Speed of dismissal suggests a private deal, not a concession
Twelve days is far too short for substantive Federal Circuit activity. The mutual cost-bearing order reinforces that both parties agreed to exit. Companies monitoring the ESL space should treat this as a potential indicator of a commercial resolution — licensing, cross-licensing, or settlement — rather than a capitulation by Hanshow.
US10674340B2 remains live and enforceable — FTO exposure persists
Because no court ruled on validity, US10674340B2 retains full presumption of validity. Competitors in the spatially organised wireless communication and electronic shelf label market should assess their freedom-to-operate exposure against this patent independently of this case’s outcome.
Hanshow v SES-Imagotag — key questions answered
The Federal Circuit dismissed the appeal voluntarily by agreement of both parties under Fed. R. App. P. 42(b), just 12 days after filing. No merits ruling was issued on the patentability of US10674340B2. Each side was ordered to bear its own costs.
Yes. Because the Federal Circuit issued no ruling on validity, US10674340B2 retains its full presumption of validity. The voluntary dismissal does not constitute a finding that the patent is valid or invalid — the patentability question was never adjudicated on the merits.
Potentially. The Federal Circuit’s dismissal order does not specify whether the dismissal is with or without prejudice. If without prejudice, Hanshow or a third party may be able to re-challenge the patent’s validity through a PTAB inter partes review or other proceedings. The public record does not resolve this question.
Twelve days is far too short for any substantive Federal Circuit briefing or oral argument schedule. This timing strongly suggests the parties reached a private arrangement — likely a settlement or licensing agreement — before meaningful appellate activity began. The mutual cost-bearing order is consistent with a negotiated resolution.
US10674340B2, filed under application number US16/281190, is a patent held by SES-Imagotag covering a system and method for communicating spatially organized information.
