Foto Electric Supply v. Marut Enterprises: Federal Circuit Appeal Dismissed in 138 Days
Foto Electric Supply Co., Inc. brought an infringement appeal to the Federal Circuit against Marut Enterprises LLC, asserting patents covering back-shaver devices including the GEM 107/108 and MANGROOMER® line. The appellant voluntarily dismissed its own appeal under FRAP 42(b) after just 138 days, citing Marut’s continued inaction — with each party bearing its own costs.
Back-Shaver Patent Appeal Ends Without Merits Ruling at Federal Circuit
Foto Electric Supply Co., Inc. (Fesco) filed this appeal at the Court of Appeals for the Federal Circuit on 1 May 2025, docketed as Case No. 25-1726. The dispute centred on two patents — utility patent US7856725B2 and design patent USD0611653S — covering back-shaver devices, specifically Fesco’s redesigned GEM 107/108 products featuring a 150-degree angle, and the MANGROOMER® back hair shaver line associated with Marut Enterprises LLC. The underlying action was framed as a patent infringement claim.
On 16 September 2025, Fesco moved to dismiss its own appeal pursuant to Federal Rule of Appellate Procedure 42(b), stating the appeal was ‘no longer necessary’ in light of Marut’s ‘continued inaction.’ Marut did not oppose dismissal, though it formally disagreed with the characterisation in Fesco’s motion. The Federal Circuit granted the motion to the limited extent of dismissing the appeal, ordering each party to bear its own costs — meaning no merits adjudication was reached and no judicial finding of infringement or validity was made.
The 138-day duration suggests the parties never reached substantive appellate briefing before Fesco concluded the appeal had served its purpose — or that a commercial resolution was reached outside the court record. The reference to Marut’s ‘continued inaction’ is consistent with a scenario where the underlying competitive threat had dissipated, though the public record does not confirm any settlement. What remains unknown is whether any district court proceedings underpin this appeal, and what specifically prompted Fesco’s decision to withdraw.

Appeal dismissed under FRAP 42(b): what the order means for both parties
FRAP 42(b) voluntary dismissal — no merits adjudicated
Federal Rule of Appellate Procedure 42(b) allows an appellant to dismiss its own appeal by motion. The Federal Circuit granted this motion solely to the extent of dismissing the appeal — meaning no panel reviewed the merits of the infringement claims, no claim construction was issued, and neither patent’s validity nor enforceability was addressed. The dismissal is procedural, not substantive.
Procedural dismissalPublic record is silent on prejudice designation
The order does not expressly state whether the dismissal is with or without prejudice. Under FRAP 42(b), appellate dismissals can carry different implications depending on the underlying district court posture. Because the public record here does not specify, practitioners should not assume either party is barred from future action on these patents based on this dismissal alone. The district court record, if any, would govern re-filing rights.
Prejudice status unclearFesco withdraws — ‘continued inaction’ cited as rationale
Fesco’s stated basis — that the appeal was ‘no longer necessary’ due to Marut’s ‘continued inaction’ — suggests the competitive or commercial threat that motivated the appeal may have abated. Fesco retains its patent rights in US7856725B2 and USD0611653S. No adverse finding was entered against it. However, Fesco absorbs its own appellate legal costs with no cost recovery from Marut.
Appellant bears own costsMarut survives appeal without merits defence — for now
Marut did not oppose dismissal, achieving exit from the Federal Circuit appeal without a merits ruling being rendered against it. Marut formally distanced itself from Fesco’s characterisation of the facts, preserving its litigation posture. Each party bearing its own costs means Marut receives no cost award. The MANGROOMER® product line faces no court-ordered restriction, though Fesco’s patents remain in force and could anchor future enforcement action.

Official order — verbatim text
The Federal Circuit’s order is deliberately narrow: it grants Fesco’s FRAP 42(b) motion ‘only to the extent the appeal is dismissed,’ with each party bearing its own costs. The court made no finding on infringement, validity, or claim scope of US7856725B2 or USD0611653S. Marut’s formal disagreement with Fesco’s motion characterisation is preserved in the record but carries no legal effect on the dismissal. The cost-neutral order suggests neither party extracted a concession at the appellate stage.
US7856725B2 & USD0611653S — Back-Shaver Device Utility and Design Patents
US7856725B2 is a utility patent protecting the functional architecture of a back-shaver device — specifically associated with the GEM 107/108 product line featuring a 150-degree blade angle, a configuration claimed to improve ergonomic reach and shaving efficiency. USD0611653S is a companion design patent protecting the ornamental appearance of the device. Together, these patents represent both the how-it-works and how-it-looks dimensions of Fesco’s back-shaver IP portfolio, filed under application numbers US11/442099 and US29/316404 respectively.
In the consumer personal care hardware sector, dual utility-and-design patent coverage on a single product creates compounding enforcement risk for competitors. The utility patent’s claim scope around the 150-degree angle geometry may capture functionally similar designs even when appearance differs, while the design patent addresses visual copycats. Because neither patent was construed or adjudicated in this Federal Circuit proceeding, their enforceability remains intact — and potentially untested against Marut’s MANGROOMER® product configuration in any definitive judicial forum.
Should you run an FTO against US7856725B2 and USD0611653S?
Any company designing, importing, or commercialising back-shaver devices — particularly those featuring angled blade geometries or ergonomic handles — should treat these two patents as live FTO risks. US7856725B2’s claims around the 150-degree angle feature have never been narrowed by claim construction in a published ruling. USD0611653S’s ornamental scope for the shaver’s overall form factor is similarly unlitigated at the merits level. This gap in the judicial record means product teams cannot rely on court-narrowed claims to define safe design-around space.
PatSnap Eureka’s FTO Search Agent allows R&D and IP teams to map pending product specifications against the claim language of US7856725B2 and the ornamental scope of USD0611653S in minutes. The platform surfaces related prior art, identifies design-around pathways, and flags any continuation or related applications that could extend the patent family’s reach — giving product teams the clearance confidence they need before launch.

What this case signals for the personal care device IP landscape
A voluntary Federal Circuit dismissal citing competitor inaction is a commercially significant signal in design-patent-intensive consumer product sectors.
Design and utility patent stacking remains a viable enforcement lever
Fesco’s dual assertion of a utility patent (US7856725B2) and a design patent (USD0611653S) on back-shaver devices illustrates a common stack strategy in consumer hardware. Even without a merits ruling, the filing itself may have achieved a deterrent effect — consistent with Fesco’s claim that Marut’s ‘continued inaction’ made the appeal unnecessary.
FRAP 42(b) dismissals signal commercial resolution or dissipated threat
When an appellant voluntarily dismisses at the Federal Circuit before briefing concludes, it typically signals either an out-of-court resolution or a strategic reassessment. IP teams monitoring competitor patent behaviour should treat such dismissals as indicators of shifting commercial dynamics rather than patent weakness — the underlying IP remains fully enforceable.
FOTO v MARUT — key questions answered
Foto Electric Supply Co. voluntarily dismissed its Federal Circuit appeal against Marut Enterprises LLC under FRAP 42(b), citing Marut’s ‘continued inaction.’ The court granted the motion solely to dismiss the appeal, with each party bearing its own costs. No merits ruling on infringement or patent validity was issued.
Two patents were asserted: US7856725B2 (utility patent covering the back-shaver device, associated with the GEM 107/108 featuring a 150-degree blade angle, application no. US11/442099) and USD0611653S (design patent for the ornamental appearance of the device, application no. US29/316404).
No. A voluntary dismissal under FRAP 42(b) is purely procedural — the Federal Circuit made no finding on the merits, claim scope, validity, or enforceability of US7856725B2 or USD0611653S. Both patents remain in force and could be asserted in future proceedings.
It means neither Fesco nor Marut recovered appellate costs from the other party. Typically in a FRAP 42(b) dismissal, costs may be taxed against the dismissing party; the court’s cost-neutral order here suggests either a negotiated arrangement or the court’s standard practice in consent dismissals where the opposing party does not oppose.
The dispute involved Fesco’s redesigned GEM 107/108 back-shaver devices (second generation, featuring a 150-degree blade angle) and Marut Enterprises LLC’s MANGROOMER® back hair shaver products. The infringement action concerned whether Marut’s products encroached on Fesco’s utility and design patent rights in these personal care devices.
