WFR IP, LLC v. Kohl’s, Inc. — Wireless Earpiece Patent Suit Dismissed With Prejudice
WFR IP, LLC asserted US7505793B2 — a wireless earpiece and wearable device patent — against retailer Kohl’s, Inc. in the Eastern District of Texas. The parties filed a joint stipulation of dismissal with prejudice after 271 days, with each side bearing its own costs and attorneys’ fees, suggesting a confidential resolution.
Wireless earpiece patent claim against Kohl’s ends in permanent dismissal
WFR IP, LLC filed suit against Kohl’s, Inc. on December 20, 2023 in the Eastern District of Texas (Case No. 2:23-cv-00618), asserting infringement of US7505793B2. The patent covers wireless earpiece and wearable device technology, and WFR IP alleged that Kohl’s had infringed through the sale and distribution of wireless earpiece and wearable products via its website and other retail channels. WFR IP was represented by Ramey LLP and Blank Rome LLP (Houston), while Kohl’s retained Alston & Bird, LLP.
The case closed on September 16, 2024, after only 271 days, when the parties filed a Joint Stipulation of Dismissal with Prejudice. The Eastern District Court accepted and acknowledged the stipulation, dismissing all claims and causes of action with prejudice. Critically, the order specified that each party shall bear its own costs, expenses, and attorneys’ fees — a fee-neutral resolution that neither confirms nor denies a monetary settlement between the parties.
The speed of resolution — under nine months — is notably faster than the typical E.D. Texas patent litigation lifecycle and suggests the parties reached a private agreement relatively early in the proceedings. A dismissal with prejudice forecloses WFR IP from reasserting the same patent claims against Kohl’s in the future. The public record does not disclose whether a licensing arrangement or other commercial terms were agreed, and no trial or claim construction proceedings appear to have occurred.

Dismissed with prejudice: what the joint stipulation means for both parties
Joint stipulation dismissal with prejudice explained
A dismissal with prejudice entered on joint stipulation is a consensual, permanent termination of the litigation. Under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), parties may jointly stipulate to dismiss without court approval, though here the court formally accepted the stipulation. ‘With prejudice’ means WFR IP cannot re-file the same claims against Kohl’s based on US7505793B2. The case ends on the merits as a matter of law, regardless of whether a settlement was reached.
Permanent bar on re-filingWFR IP surrenders right to sue Kohl’s again on this patent
By agreeing to a with-prejudice dismissal, WFR IP permanently waives the right to bring the same US7505793B2 claims against Kohl’s. This is a stronger concession than a without-prejudice dismissal. The fee-neutral order — each party bearing its own costs — is consistent with a private licensing deal or nuisance-value settlement, but the public record is silent on financial terms. WFR IP retains the patent and may assert it against other defendants.
Patent survives; this defendant releasedKohl’s secures permanent peace on US7505793B2 claims
Kohl’s exits the litigation having secured a with-prejudice dismissal, meaning WFR IP cannot re-assert these specific claims in a new action. The absence of a fee award against WFR IP suggests Kohl’s did not pursue an exceptional-case fee motion under 35 U.S.C. § 285, which is typical where parties prefer a clean, low-profile exit. Kohl’s wireless earpiece and wearable product lines are now clear of this particular patent threat.
Permanent release from this claimWireless wearable retailers face continued PAE assertion risk
This case is consistent with a broader pattern of patent assertion entities targeting consumer electronics retailers over wireless earpiece and wearable technology in E.D. Texas. A swift, fee-neutral dismissal with prejudice typically signals a confidential resolution rather than a defendant win on the merits. Other retailers and distributors of wireless earpiece products should note that US7505793B2 remains active and may be asserted against non-settling parties. FTO analysis against this patent remains commercially relevant.

Official order — verbatim text
The court’s order accepts the parties’ joint stipulation verbatim, confirming that all claims and causes of action are dismissed with prejudice, with no fee award to either side. The ‘each party bears its own costs’ language is significant: it forecloses a later fee motion under 35 U.S.C. § 285 and is consistent with a negotiated exit rather than a litigated outcome. The order’s denial of all pending relief as moot confirms no substantive motions were resolved on the merits before the dismissal was entered.
US7505793B2 — wireless earpiece and wearable device technology
US7505793B2, filed under application number US11/218392, covers wireless earpiece and wearable device technology. The patent sits within the consumer electronics and wireless communication domain, addressing the design and functionality of earpiece devices capable of wireless operation. Its application date places it in the mid-2000s wave of Bluetooth and short-range wireless audio innovation, a period that generated a dense thicket of foundational wireless earpiece patents still subject to active assertion today.
For consumer electronics retailers and distributors, US7505793B2 represents a meaningful assertion risk. WFR IP’s selection of Kohl’s — a general merchandise retailer rather than a technology manufacturer — suggests the patent’s claims are being applied broadly to the retail distribution of wireless earpiece products. This is a common enforcement strategy: targeting downstream retailers who lack the technical resources to mount a full prior art defence, increasing the commercial pressure to settle. The patent remains live and its assertion scope has not been adjudicated on the merits in this case.
Should you run an FTO analysis against US7505793B2?
Any company selling, distributing, or sourcing wireless earpiece or wearable audio products for the U.S. market should treat US7505793B2 as a live risk. The Kohl’s case demonstrates that WFR IP is willing to target major retailers — not just manufacturers — for alleged infringement. Given that no merits adjudication occurred and the patent survived unchallenged, its claim scope remains intact. R&D and procurement teams introducing new wireless earpiece SKUs or expanding wearable audio product lines should prioritise FTO clearance.
PatSnap Eureka’s FTO Search Agent enables IP and R&D teams to map the claim landscape of US7505793B2 against specific product categories, identify prior art that could support an IPR petition, and flag related patents in WFR IP’s portfolio that may present additional exposure.

What this case signals for the wireless wearable retail IP landscape
A fast, fee-neutral dismissal with prejudice in E.D. Texas is a recognisable pattern in PAE enforcement — here’s what it means for the sector.
E.D. Texas remains a preferred venue for wireless wearable PAE actions
WFR IP’s choice of the Eastern District of Texas for a wireless earpiece infringement suit follows a well-established playbook. The district’s patent-friendly procedural history and plaintiff-favourable scheduling norms continue to attract patent assertion entities targeting consumer electronics retailers. Companies selling wireless or wearable audio products through U.S. retail channels should monitor this venue closely.
Fee-neutral terms signal a private resolution, not a defendant victory
When a PAE and a major retailer agree to a with-prejudice dismissal where each party bears its own fees, it rarely reflects a clean defendant win. It more typically suggests the defendant paid or granted something of value privately. Kohl’s counsel at Alston & Bird did not pursue a § 285 fee motion, reinforcing the view that the case resolved commercially rather than on merits grounds.
WFR v Kohl’s — key questions answered
The dismissal with prejudice entered in Case No. 2:23-cv-00618 permanently bars WFR IP from reasserting the same US7505793B2 claims against Kohl’s. However, it does not extinguish the patent itself. WFR IP retains the right to enforce US7505793B2 against other defendants not party to this stipulation.
No merits adjudication occurred in WFR IP v. Kohl’s. The case was resolved via a joint stipulation of dismissal with prejudice, with each party bearing its own costs. The public record does not disclose whether a licensing payment or other commercial terms were agreed. A with-prejudice dismissal without a fee award does not constitute a court finding of non-infringement or invalidity.
US7505793B2, filed under application US11/218392, covers wireless earpiece and wearable device technology in the consumer electronics and wireless communication domain. In this litigation, the patent was asserted by WFR IP, LLC, a patent assertion entity. The patent remains active following the dismissal of the Kohl’s action.
Targeting downstream retailers is a recognised PAE enforcement strategy. Retailers typically lack deep technical IP litigation resources and face commercial pressure to resolve cases quickly to avoid disruption to product lines. Suing a high-profile retailer like Kohl’s may also signal to other potential defendants that the patent holder is actively enforcing, potentially encouraging licensing discussions across the sector.
The fee-neutral order in WFR IP v. Kohl’s means neither party can pursue a subsequent cost recovery or fee motion arising from this litigation. Under 35 U.S.C. § 285, a prevailing party may seek attorneys’ fees in exceptional cases. The absence of any such motion, combined with the joint stipulation, is consistent with a negotiated commercial resolution and suggests Kohl’s did not obtain the kind of clear litigation victory that would support an exceptional-case fee award.
