Cherry Optical v. Inland Diamond Products: Federal Circuit Appeal Dismissed
Cherry Optical, Inc. brought an infringement appeal against Inland Diamond Products, Co. before the U.S. Court of Appeals for the Federal Circuit, asserting two patents covering beveling wheels and beveled eyeglass lenses. The appeal was dismissed without a merits ruling after 582 days, leaving the underlying infringement dispute unresolved on the public record.
Federal Circuit dismisses Cherry Optical’s eyeglass lens beveling appeal
Cherry Optical, Inc. filed Case No. 24-1560 at the U.S. Court of Appeals for the Federal Circuit on 12 March 2024, appealing an infringement dispute against Inland Diamond Products, Co. The case centred on two patents — US9405130B2 and US8636360B2 — covering a beveling wheel, a method for forming a beveled lens for use with eyeglasses, and the beveled lens itself. These patents protect precision optical finishing technology used in the production of prescription eyewear.
The Federal Circuit closed the appeal on 15 October 2025 with an order of dismissal. The verdict record states the cause was ‘DISMISSED’ and the basis of termination is recorded as ‘Appeal Dismissed.’ A procedural dismissal at the appellate level means the court did not reach the substantive merits of the infringement claims — neither party received a ruling on patent validity or infringement liability. The dismissal leaves the posture of the underlying district-level dispute unchanged, at least as far as the public record reveals.
At 582 days, the appeal’s duration is consistent with a matter that progressed through briefing before being resolved on procedural grounds rather than a swift early dismissal. The public record does not disclose whether the dismissal followed a settlement between the parties, a jurisdictional defect, or a voluntary withdrawal by Cherry Optical. What remains unknown is whether the parties reached a commercial resolution and what the current enforceability status of both patents is in the context of this dispute.

Federal Circuit dismissal: what the procedural ending means for both parties
Appeal dismissed without a merits ruling
A Federal Circuit dismissal on procedural grounds means the appellate court never evaluated whether the district court below erred on infringement or validity. The order ‘DISMISSED’ forecloses this appeal path but does not, by itself, resolve the underlying patent dispute. Common procedural grounds include lack of jurisdiction, failure to prosecute, or voluntary withdrawal — the public record is silent on which applied here.
No merits adjudicationCherry Optical loses appellate avenue without vindication
As appellant, Cherry Optical brought this case to the Federal Circuit seeking a favourable ruling on its beveling lens patents. A dismissal without merits review means Cherry Optical did not obtain the appellate affirmance or reversal it sought. Whether the patents remain commercially enforceable against Inland Diamond Products depends on what — if anything — was resolved at the district level before this appeal was filed and dismissed.
Appellate relief deniedInland Diamond avoids Federal Circuit merits exposure
Inland Diamond Products, as appellee, benefits from the dismissal in the sense that no Federal Circuit ruling on the asserted patents was entered against it. However, the absence of a merits ruling also means there is no formal finding of non-infringement or invalidity that Inland Diamond can rely on as precedent. The company’s IP risk from US9405130B2 and US8636360B2 remains technically unresolved on the public record.
No adverse merits findingOptical lens finishing IP landscape left unresolved
For manufacturers of beveling wheels, grinding tools, and precision optical finishing equipment, this dismissal provides no clarifying guidance on the scope or validity of the Cherry Optical patents. Competitors and component suppliers in the ophthalmic lens processing sector cannot rely on this Federal Circuit outcome as a safe harbour. An independent freedom-to-operate analysis against US9405130B2 and US8636360B2 remains advisable for any party active in this technology space.

Official order — verbatim text
The Federal Circuit’s order — ‘THIS CAUSE having been considered, it is ORDERED AND ADJUDGED: DISMISSED’ — is a procedural disposition. It indicates the court terminated the appeal without issuing a ruling on the substantive infringement or validity questions raised by Cherry Optical. No opinion on claim construction, infringement, or patent scope was published. For both parties, the dismissal resets the litigation posture to whatever state the district-level proceedings had reached prior to the appeal, and neither party can rely on this Federal Circuit outcome as binding precedent on the merits.
US9405130B2 & US8636360B2 — Beveling wheel and beveled eyeglass lens technology
US9405130B2 (application US14/589198) and US8636360B2 (application US12/540181) together cover the hardware and process claims at the heart of this dispute. The patents protect a beveling wheel — the precision abrasive tool used to grind the characteristic V-shaped edge profile onto ophthalmic lenses — as well as the method by which that bevel is formed and the resulting beveled lens product. Both patents fall within the precision optical manufacturing domain, addressing the mechanical interface between lens blanks and eyeglass frames.
For the ophthalmic lens processing industry, these patents matter because beveling is a ubiquitous finishing step in prescription eyewear manufacture. Any tool supplier, lens lab, or OEM that produces or sells beveling wheels or finished beveled lenses in the U.S. market sits within the potential claim scope. The fact that Cherry Optical pursued Federal Circuit-level litigation suggests it views these patents as commercially significant enforcement assets, raising the profile of both grants for competitors and investors monitoring the optical finishing IP landscape.
Should you run an FTO against US9405130B2 and US8636360B2?
Product teams and supply chain managers working on ophthalmic lens finishing equipment — including beveling wheels, CNC edging machines, and lens processing systems — should treat both patents as live risk items. The Federal Circuit dismissal issued no narrowing claim construction and no invalidity finding. If your product touches the beveling wheel geometry, lens edge formation methods, or beveled lens specifications described in these grants, an FTO analysis is warranted before commercialisation or market expansion in the United States.

What this case signals for the ophthalmic lens processing IP landscape
A procedural Federal Circuit dismissal in an eyeglass lens beveling patent dispute leaves enforcement risk alive for the broader optical finishing sector.
Procedural dismissal does not extinguish the underlying patent risk
US9405130B2 and US8636360B2 remain granted patents with no Federal Circuit invalidity ruling against them. Companies producing or supplying beveling wheels and related optical finishing tools should not interpret this dismissal as a clearance event. The patents’ claims retain their presumption of validity under 35 U.S.C. § 282.
Duration suggests briefing progressed before resolution — monitor for refiling
At 582 days, this appeal ran long enough to suggest substantive activity before dismissal. That pattern is consistent with either a negotiated resolution or late-stage procedural barrier. IP teams should monitor Cherry Optical’s enforcement activity in district courts for any refiled or related actions asserting these patents against optical tool manufacturers.
Cherry v Inland — key questions answered
The Federal Circuit dismissed Cherry Optical’s appeal in Case No. 24-1560 on 15 October 2025. The appeal involved infringement claims over US9405130B2 and US8636360B2, covering beveling wheels and beveled eyeglass lenses. The court issued a procedural dismissal without reaching the merits of the infringement dispute. No invalidity or non-infringement ruling was entered.
Cherry Optical asserted two patents: US9405130B2 (application US14/589198) and US8636360B2 (application US12/540181). Both patents relate to beveling wheel technology, the method of forming a beveled lens for use with eyeglasses, and the beveled lens product itself — core components in precision ophthalmic lens finishing.
A Federal Circuit dismissal on procedural grounds does not invalidate the patents or render them unenforceable. US9405130B2 and US8636360B2 retain their presumption of validity under U.S. patent law. No claim construction or invalidity ruling was issued. The patents remain live enforcement assets that Cherry Optical could assert in future district court proceedings.
The 582-day duration is consistent with an appeal that progressed through appellate briefing before being resolved on procedural grounds. The public record does not disclose the specific reason for dismissal — possible causes include voluntary withdrawal, a negotiated settlement, or a jurisdictional defect identified late in proceedings. The extended timeline suggests the matter was substantively active rather than dismissed immediately at inception.
No. Because the dismissal was procedural and no merits ruling was issued, the Federal Circuit’s order cannot be relied upon as precedent on infringement or validity. Manufacturers of beveling wheels, ophthalmic lens finishing equipment, or beveled lenses for eyeglasses remain exposed to claims under the as-granted scope of US9405130B2 and US8636360B2. An independent freedom-to-operate analysis is strongly advisable for any party active in this product category.
