Sorrell Holdings v. Infinity Headwear: Federal Circuit Remands Body Washing Device Patent Appeal
Sorrell Holdings, LLC asserted US6887007B2 — a patent covering a hand-held body washing device — against Infinity Headwear & Apparel, LLC in an infringement action that reached the Court of Appeals for the Federal Circuit. After 586 days, the Federal Circuit issued a split decision: affirming in part, vacating in part, and remanding the case for further proceedings.
Split Federal Circuit ruling sends body-washing device case back down
Sorrell Holdings, LLC filed Case No. 22-1964 at the Court of Appeals for the Federal Circuit on 29 June 2022, appealing a lower-court outcome in an infringement action centred on US6887007B2. That patent, applied under application number US10/165149, protects a hand-held body washing device — a personal care product in the consumer goods and hygiene hardware space. The defendant, Infinity Headwear & Apparel, LLC, contested the infringement claims through counsel at Friday, Eldredge & Clark, LLP.
The Federal Circuit closed the appeal on 5 February 2024, delivering a verdict of affirmed-in-part, vacated-in-part, and remanded. This split outcome means the appellate court agreed with some conclusions from the proceedings below, disagreed with others sufficiently to vacate those portions, and sent the case back to the originating tribunal for further adjudication consistent with its guidance. Neither party achieved a clean win at this stage.
The 586-day appellate timeline is consistent with typical Federal Circuit patent appeal durations, which often run 18–24 months. The remand structure suggests the court identified at least one reversible error — likely in claim construction, damages methodology, or a liability determination — while preserving other findings. What remains unknown from the public record is the specific legal question the remand targets and the scope of proceedings now required below, which will determine whether the dispute is resolved through further litigation or eventual settlement.

586 days from filing to Federal Circuit decision — a complex appellate journey
What ‘Affirmed-in-Part, Vacated-in-Part, and Remanded’ means for both parties
What a split Federal Circuit affirmance and vacatur means
An affirmed-in-part, vacated-in-part, remanded verdict indicates the Federal Circuit reviewed multiple distinct issues on appeal and reached different conclusions on each. Portions affirmed stand as final on those points. Portions vacated are nullified — the lower court’s rulings on those issues no longer have legal effect. The remand instructs the originating court to reconsider those vacated questions under the Federal Circuit’s guidance.
Partial vacatur + remandSorrell Holdings: partial win, but litigation continues
For Sorrell Holdings, the affirmed portions represent a preserved victory on those specific issues — findings in its favour that Infinity Headwear cannot re-litigate on those grounds. However, the vacated portions mean Sorrell did not obtain a complete appellate win. The remand reopens proceedings below, maintaining litigation costs and uncertainty. Whether the remand ultimately favours Sorrell depends on how the lower court resolves the remaining questions.
Litigation ongoingInfinity Headwear: vacatur offers a second chance on key issues
The vacatur gives Infinity Headwear & Apparel a meaningful opportunity: rulings previously against it on the vacated issues are wiped, and the lower court must reconsider them. This could affect liability findings, damages calculations, or both. The affirmed portions, however, remain binding — Infinity cannot re-challenge those points. The remand likely prolongs the dispute, but the partial vacatur suggests Infinity’s appellate arguments had merit on at least some issues.
Vacatur provides reliefRemand: what the lower court must now do
On remand, the originating tribunal must address the vacated issues in accordance with the Federal Circuit’s opinion. Depending on the scope, this may involve re-trying damages, revisiting claim construction for specific patent terms, or re-evaluating particular infringement findings. The parties may also elect to settle before the remand proceedings conclude. Until the lower court issues a new ruling, the case remains substantively unresolved on the remanded questions.

Stipulation of dismissal — official text
The Federal Circuit’s verdict of ‘Affirmed-in-Part, Vacated-in-Part, and Remanded’ is a compound disposition indicating the court resolved multiple appellate issues differently. The affirmance preserves some lower-court findings as final; the vacatur legally nullifies others, stripping them of precedential or binding effect for both parties. The remand instruction requires the originating court to revisit the vacated issues under the Federal Circuit’s analytical framework. This outcome leaves the ultimate infringement and/or damages determination on the remanded questions formally open, meaning neither party has yet obtained a final dispositive ruling on all contested matters.
US6887007B2 — Hand-Held Body Washing Device
US6887007B2, filed under application number US10/165149, protects a hand-held body washing device — a consumer personal care product designed for bathing or skin-cleansing use. The patent sits within the broader consumer hygiene hardware domain, an area that encompasses ergonomic grip designs, fluid-dispensing mechanisms, and skin-contact applicator technologies. As a granted utility patent (B2 designation indicates it was published post-grant), the claims define the protected technical scope that competitors must design around.
The enforcement of US6887007B2 against a headwear and apparel company suggests either that Infinity Headwear diversified into personal care products or that the patent’s claims are broad enough to capture product configurations beyond traditional body-wash hardware. For competitors and product developers in the personal care accessories market, the unsettled claim construction resulting from the remand increases uncertainty about the patent’s enforceable boundaries — making active monitoring of post-remand proceedings commercially important.
Should you run an FTO analysis against US6887007B2?
Any company developing or sourcing hand-held body washing devices, personal bathing accessories, or ergonomic skin-care applicators should treat US6887007B2 as a live risk until the remanded proceedings reach a final resolution. The ongoing litigation and unsettled claim scope mean the patent’s enforceable boundaries remain in flux — which is precisely the environment where an FTO gap can emerge unexpectedly.

What this appeal signals for personal care device IP enforcement
A split Federal Circuit outcome in a consumer device patent case signals nuanced claim-scope disputes that warrant close monitoring.
Remands signal claim construction disputes — audit your product scope now
Federal Circuit remands in infringement cases most commonly stem from reversible claim construction errors. If you operate in the personal care or body-washing device market, a remand in this case means the applicable patent scope has not been finally settled. Companies with products in adjacent categories should treat the remanded questions as an ongoing risk signal until the lower court issues its final ruling.
US6887007B2 remains an active enforcement risk until final resolution
Because the case has been remanded rather than dismissed, US6887007B2 retains full enforceability. Sorrell Holdings can continue asserting the patent against Infinity Headwear and, separately, against other parties. Product teams developing hand-held bathing or body-washing hardware should ensure any FTO analysis accounts for the unsettled claim scope resulting from this appeal.
Sorrell v Infinity — key questions answered
The Court of Appeals for the Federal Circuit issued a verdict of affirmed-in-part, vacated-in-part, and remanded on 5 February 2024. Some lower-court findings were preserved; others were vacated. The case was returned to the originating court for further proceedings on the remanded issues, meaning final resolution had not been reached as of the close date.
The patent at issue is US6887007B2, applied under application number US10/165149. It covers a hand-held body washing device in the personal care and consumer hygiene hardware space. The patent is held by Sorrell Holdings, LLC and was asserted against Infinity Headwear & Apparel, LLC in an infringement action.
This compound disposition means the Federal Circuit agreed with some lower-court conclusions (affirmed), disagreed with and nullified others (vacated), and sent the case back to the lower court (remanded) to reconsider the vacated issues using the appellate court’s guidance. Neither party achieves a complete win, and the case continues below on the remanded questions.
After remand, the originating court must address the specific issues identified by the Federal Circuit — which may include claim construction, damages, or particular liability findings. Proceedings can involve further hearings or briefing. Parties sometimes reach a negotiated settlement before the remand concludes. A new judgment from the lower court may itself be subject to further appeal.
