ProudLion IP v. Fossil Group: Smartwatch Patent Suit Dismissed With Prejudice
ProudLion IP, LLC filed a patent infringement action against Fossil Group in the Western District of Texas, asserting US9967389B2 against Fossil’s smartwatch line. The parties jointly stipulated to dismiss all claims within 260 days — plaintiff’s claims dismissed with prejudice, signalling a likely settlement or licence resolution.
A Quick Exit in W.D. Texas: Smartwatch IP Claim Ends by Joint Stipulation
On June 5, 2023, ProudLion IP, LLC — a non-practising entity represented by Ramey LLP — filed a patent infringement complaint against Fossil Group, Inc. in the Western District of Texas, Austin Division, before Chief Judge Robert Pitman. The sole patent asserted was US9967389B2, targeting Fossil’s smartwatch product line. Fossil retained Fish & Richardson LLP, a firm with a strong track record defending against NPE assertions in W.D. Texas.
On February 16, 2024 — 260 days after filing — the parties filed a joint stipulation of dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Under that rule, the stipulation became effective automatically upon filing without requiring judicial approval. Critically, ProudLion’s infringement claims were dismissed with prejudice, meaning they cannot be refiled, while Fossil’s counterclaims were dismissed without prejudice, preserving Fossil’s ability to reassert them in future proceedings.
The asymmetric dismissal terms — plaintiff with prejudice, defendant without — are consistent with a negotiated resolution, most likely a licence or covenant not to sue granted to Fossil. The public record does not disclose any financial terms. The sub-nine-month duration suggests early resolution, potentially following claim construction exchanges or pre-trial motion pressure. What remains unknown is whether a licence was granted, and on what scope.

Joint stipulation under Rule 41: what the dismissal terms mean for each party
Rule 41(a)(1)(A)(ii) dismissal requires no court approval
A joint stipulation under Fed. R. Civ. P. 41(a)(1)(A)(ii) is self-executing — it takes effect the moment it is filed and does not require a judge’s signature or order. The court’s February 20 order simply acknowledged the filing and administratively closed the docket. This mechanism is commonly used when parties have reached a private resolution and wish to end proceedings quickly and cleanly.
Procedural dismissalProudLion’s claims dismissed with prejudice — no second bite
Dismissal with prejudice of ProudLion’s claims operates as a final adjudication on the merits for res judicata purposes. ProudLion cannot refile the same infringement claims against Fossil based on US9967389B2 for the same accused products. This outcome is consistent with ProudLion having obtained a licence or other commercial consideration from Fossil, making further litigation unnecessary and legally barred.
Claims permanently barredFossil’s counterclaims survive — dismissed without prejudice
Fossil’s counterclaims — likely invalidity or non-infringement declarations — were dismissed without prejudice, meaning Fossil retains the right to reassert them in future proceedings. This asymmetry is a standard negotiating outcome that protects the defendant’s leverage: if ProudLion were to assert the patent again (against different products or in different contexts), Fossil’s invalidity arguments remain available.
Defendant’s options preservedLikely licence signals ongoing smartwatch IP exposure for the sector
The structure of this dismissal — particularly the with-prejudice bar on plaintiff’s claims — is consistent with ProudLion having extracted a commercial outcome from Fossil. Other smartwatch OEMs and wearable device makers operating in similar technology spaces covered by US9967389B2 should note that this patent remains in force and that ProudLion’s monetisation strategy appears active. An FTO assessment against this patent is advisable for competitors.

Official order — verbatim text
The dismissal order reflects the automatic operation of Rule 41(a)(1)(A)(ii): the court exercises no discretion and makes no merits determination. The asymmetric prejudice terms — plaintiff with prejudice, defendant without — are the operative commercial signal. They confirm ProudLion accepted a bar on future assertion against Fossil, while Fossil preserved its invalidity arguments. No damages, injunction, or claim construction ruling was issued.
US9967389B2 — Smartwatch communication and data technology
US9967389B2 is a United States utility patent with application number US15/654609. The patent covers technology in the smartwatch and wearable device domain, specifically relating to communication and data functionality deployed in consumer wearable devices. The application’s filing and prosecution history places it within the broader wave of wearable technology patents that emerged as the smartwatch category matured commercially. ProudLion IP, LLC holds this patent as part of what appears to be an active licensing and enforcement programme.
From a competitive intelligence standpoint, US9967389B2 sits in a technology space contested by major smartwatch and wearable OEMs including Apple, Samsung, Garmin, and Fitbit, in addition to Fossil Group. The fact that ProudLion targeted Fossil — a significant mid-market smartwatch player — suggests the patent’s claims are broad enough to read on widely deployed wearable architectures. Any competitor shipping smartwatches or wrist-worn connected devices with similar communication or data management functionality should treat this patent as a live enforcement risk.

If your organisation designs, manufactures, or imports smartwatches or wrist-worn connected devices into the US market, US9967389B2 warrants attention.

The patent was not invalidated in this proceeding, meaning its claims remain fully enforceable. Product teams shipping devices with onboard communication modules or data synchronisation features should conduct a targeted FTO review.

NPE speed matters: Ramey LLP filed and resolved in under nine months

Cases of this structure — single patent, single defendant, quick joint dismissal — typically signal a licensing outcome rather than litigation attrition. Companies receiving demand letters from this firm should model early resolution economics against full defence costs.
With-prejudice dismissal confirms Fossil’s exposure is resolved — for now
Fossil secured dismissal of plaintiff’s claims with prejudice, effectively insulating it from re-assertion of US9967389B2 on the same accused products. However, Fossil’s without-prejudice counterclaim dismissal means it did not secure a formal invalidity ruling — the patent itself was not cancelled or invalidated by this proceeding.
ProudLion v Fossil — key questions answered
ProudLion IP, LLC filed a patent infringement suit against Fossil Group in W.D. Texas on June 5, 2023, asserting US9967389B2 against Fossil’s smartwatches. The parties filed a joint stipulation of dismissal on February 16, 2024. ProudLion’s claims were dismissed with prejudice; Fossil’s counterclaims were dismissed without prejudice. The case was closed on February 20, 2024, after 260 days.
Dismissal with prejudice operates as a final judgment on the merits for res judicata purposes. ProudLion is permanently barred from refiling the same infringement claims against Fossil Group based on US9967389B2 for the same accused smartwatch products. This outcome is typically the result of a negotiated resolution such as a licence, covenant not to sue, or lump-sum settlement, though no financial terms are disclosed in the public record.
The asymmetric dismissal terms reflect a negotiated outcome. Fossil’s counterclaims — likely invalidity or non-infringement declarations — were dismissed without prejudice, preserving Fossil’s ability to reassert them if needed. This structure suggests Fossil obtained a licence or other resolution that made immediate pursuit of invalidity unnecessary, while retaining the option if the patent were asserted again in a different context.
Yes. The dismissal was procedural and no court made any finding regarding the validity or invalidity of US9967389B2. The patent was not cancelled, limited, or found unenforceable. ProudLion retains full ownership and enforcement rights. Other smartwatch or wearable device manufacturers operating in the US market remain potentially exposed to assertion of this patent.
W.D. Texas, Austin Division has become one of the most active patent litigation venues in the United States, particularly for NPE plaintiffs. Ramey LLP is a frequent filer in this district. The court’s historically efficient scheduling and plaintiff-friendly procedural history make it a preferred forum for licensing-oriented patent enforcement. Defendants in this district often face early settlement pressure due to predictable and fast-moving dockets.
