Atturo Tire v. Toyo Tire: Federal Circuit Splits the Difference on Tire Design Patent
Atturo Tire Corp. brought design patent infringement claims against Toyo Tire Corp. and Toyo Tire USA Corp. over tire tread design patent USD626913S. After 844 days before the Federal Circuit, the court issued a mixed ruling — affirming some claims, reversing others, and dismissing a portion of the appeal outright.
A Federal Circuit split verdict reshapes Atturo’s design patent position
Atturo Tire Corp. filed this appeal on June 13, 2022, challenging prior proceedings concerning its tire tread design patent USD626913S — a design patent protecting the ornamental appearance of a tire tread pattern. The defendants, Toyo Tire Corp. and its U.S. subsidiary Toyo Tire USA Corp., were represented by Foley & Lardner LLP, while Atturo was represented by Akerman LLP. The case originated as an infringement action, with Atturo asserting that Toyo’s tire products copied the protected design.
The Federal Circuit closed the case on October 4, 2024, issuing a verdict of affirmed-in-part, reversed-in-part, and dismissed-in-part. This three-way disposition is procedurally significant: the affirmance portion validates some aspects of the lower tribunal’s reasoning; the reversal signals the appellate court found legal error on at least one discrete issue; and the partial dismissal suggests one or more issues were not properly before the court on appeal.
The 844-day duration of this Federal Circuit appeal is consistent with complex design patent disputes that raise claim construction and substantial similarity questions. The mixed outcome suggests neither party achieved a clean appellate win, which may leave open questions around damages, injunctive relief scope, or remand proceedings. The public record does not disclose the precise grounds for each component of the split ruling, leaving the full commercial impact partially indeterminate.

Federal Circuit’s split verdict: what each part of the ruling means
What affirmed-in-part, reversed-in-part, dismissed-in-part means
A split Federal Circuit disposition is relatively uncommon and signals that the court found the lower decision correct on some issues, legally erroneous on others, and that certain issues were procedurally barred from appellate review. Each component carries independent legal weight — the reversal in particular indicates the appellate court identified a specific error warranting a different outcome on at least one claim or issue.
Mixed appellate dispositionAtturo wins some ground — and loses some
The partial affirmance preserves Atturo’s position on the issues upheld below, maintaining enforceability of USD626913S on those grounds. However, the reversal component means Atturo failed on at least one significant issue before the Federal Circuit — potentially affecting infringement findings, claim scope, or damages. The dismissed portion suggests Atturo may have pressed arguments the court found procedurally improper, which typically cannot be re-raised.
Partial win — enforceability maintained in partToyo secures a reversal — but not a clean victory
Toyo Tire’s reversal on at least one issue represents a meaningful appellate success, potentially reducing liability exposure or narrowing the scope of any infringement finding. The partial affirmance, however, means Toyo did not escape the dispute entirely. The dismissed portion may have reflected Toyo’s procedural arguments or Atturo’s overreach, but without merits adjudication on that component, Toyo’s protection is limited to affirmed and reversed issues only.
Partial reversal — liability potentially reducedDesign patent enforcement in tire markets remains contested
This mixed ruling suggests the Federal Circuit views tire tread design patent disputes with nuance, declining to grant wholesale affirmance or reversal. For tire manufacturers and aftermarket suppliers, the case signals that ornamental tread design patents can sustain infringement claims through appeal — but that overbroad enforcement attempts risk partial reversal. Competitors should treat USD626913S as an active enforcement asset with defined — though not fully public — scope.

Official order — verbatim text
The Federal Circuit’s three-part disposition — affirmed-in-part, reversed-in-part, dismissed-in-part — reflects granular appellate review across distinct issues rather than a single up-or-down merits ruling. On appeal, the Federal Circuit reviews legal questions de novo and factual findings for clear error. The reversal component indicates the court identified at least one legal error in the proceedings below, while the dismissal of a portion suggests one or more issues lacked proper appellate jurisdiction or were inadequately preserved. The net effect is a remand-likely posture on the reversed issue.
USD626913S — Ornamental Tire Tread Design Patent
USD626913S is a U.S. design patent protecting the ornamental appearance of a tire tread pattern, filed under application number US29/334700. Design patents under 35 U.S.C. §171 protect the visual, non-functional characteristics of an article of manufacture — here, the surface geometry and aesthetic configuration of a tire tread. Unlike utility patents, infringement is assessed under the ‘ordinary observer’ test: whether an ordinary observer would find the accused design substantially similar to the patented design.
For the tire sector, tread design patents represent a meaningful but often underestimated IP layer. Manufacturers differentiate on tread aesthetics alongside performance, making ornamental design rights commercially significant — particularly in aftermarket and off-road tire segments where visual identity drives purchasing. USD626913S’s survival through Federal Circuit appeal, even in partial form, reinforces that Atturo views this asset as central to its competitive positioning against larger global manufacturers including Toyo.
Should your team run an FTO check against USD626913S?
Any tire manufacturer, private-label distributor, or aftermarket supplier commercialising tread designs with visual similarities to Atturo’s patented pattern should treat USD626913S as an active enforcement risk. The Federal Circuit’s partial affirmance confirms the patent’s enforceability in at least some respects. R&D teams designing new tread patterns — particularly in the all-terrain and light truck tire segments — should validate clearance before tooling investment.

What this case signals for the tire design patent IP landscape
A split Federal Circuit ruling in a tire tread design case has layered consequences for enforcement strategy and competitor risk management.
Design patents on tire treads survive Federal Circuit scrutiny
The partial affirmance confirms that ornamental tread design patents like USD626913S can withstand appellate challenge. Tire manufacturers developing new tread patterns should treat registered design patents as credible enforcement tools — and conduct FTO analysis accordingly before commercialising new tread designs.
Mixed verdicts signal over-litigation risk for patent holders
Atturo’s failure to secure a full affirmance — with one portion reversed and another dismissed — suggests the original enforcement posture may have overreached. Design patent holders in manufacturing sectors should scope infringement claims tightly to avoid creating reversal surface area on appeal.
Atturo v Toyo — key questions answered
The Federal Circuit issued a split ruling in Case No. 22-1892: affirmed-in-part, reversed-in-part, and dismissed-in-part. The case closed on October 4, 2024, after 844 days on appeal. The reversal indicates at least one legal error in the proceedings below, while the partial dismissal suggests certain issues were not properly before the appellate court.
The patent at issue is USD626913S (application number US29/334700), a U.S. design patent protecting the ornamental appearance of a tire tread pattern. Design patents protect non-functional aesthetic characteristics and infringement is assessed under the ordinary observer test for substantial similarity.
A split Federal Circuit disposition means the court reviewed multiple distinct issues and reached different conclusions on each. Affirmance means no reversible error was found on those issues; reversal means the court identified legal error requiring a different outcome. The reversed issues are typically remanded to the lower tribunal for proceedings consistent with the appellate ruling.
The partial affirmance confirms that USD626913S retains enforceability on the issues upheld below. The reversal component may affect the scope of any infringement finding, damages award, or injunctive relief. The patent should be treated as an active enforcement asset, though the precise post-appeal scope depends on any remand proceedings.
