Ice Rover v. TackLife: Three-Patent Cooler Dispute Dismissed Without Prejudice
Ice Rover, Inc. asserted two design patents and one utility patent against TackLife’s Reyleo 50-Quart Portable Rotomolded Cooler in the Western District of Texas. After 827 days of litigation, Ice Rover voluntarily dismissed the case without prejudice under Fed. R. Civ. P. 41(a)(1)(A)(i), leaving the door open for future enforcement action.
Ice Rover’s Multi-Patent Cooler Claim Ends Without a Merits Decision
On July 19, 2022, Ice Rover, Inc. filed suit against TackLife, Inc. in the Western District of Texas (Case No. 6:22-cv-00802), asserting infringement of three patents: design patents USD893979S and USD881673S, and utility patent US10272934B2. The accused products were TackLife’s Reyleo-branded 50-Quart Portable Rotomolded Cooler (with wheels) and related cooler products. The asserted patents collectively cover the ornamental design and functional features of portable hard-sided coolers.
On October 23, 2024, Ice Rover filed a stipulated dismissal without prejudice pursuant to Fed. R. Civ. P. 41(a)(1)(A)(i), closing the case after 827 days. A dismissal without prejudice means no judgment was entered on the merits; Ice Rover retains the theoretical right to refile the same claims. TackLife received no formal adjudication of non-infringement or invalidity, meaning neither party obtained a definitive win on the underlying patent questions.
The 827-day duration before a Rule 41(a)(1)(A)(i) dismissal is notable — such dismissals can occur at any stage, but the elapsed time suggests the case progressed through at least early motion practice before resolution. The public record does not disclose whether a settlement was reached, a licensing agreement was executed, or Ice Rover simply elected to exit litigation. The absence of defendant counsel on record may suggest TackLife’s litigation posture was limited, which could have influenced the strategic calculus for both sides.

Dismissed without prejudice: what Rule 41(a)(1)(A)(i) means for each party
Rule 41(a)(1)(A)(i): plaintiff’s unilateral exit before answer
Fed. R. Civ. P. 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without a court order before the opposing party serves an answer or a motion for summary judgment. The dismissal is without prejudice by default, meaning the underlying claims are not extinguished. No judicial finding on infringement, validity, or damages was made. The procedural record does not reflect an answer filed by TackLife, which is consistent with this mechanism being available.
No merits adjudicationWithout prejudice vs. with prejudice: the critical difference
A dismissal without prejudice preserves the plaintiff’s right to refile the same claims, subject to applicable statutes of limitations and any court-imposed conditions. A dismissal with prejudice would have permanently barred Ice Rover from asserting the same patents against TackLife on the same accused products. Here, the public record confirms the dismissal is explicitly without prejudice, meaning TackLife has not secured a permanent shield against these patents. The threat of future enforcement on USD893979S, US10272934B2, and USD881673S technically remains.
Refiling remains possibleIce Rover exits without conceding invalidity or non-infringement
Ice Rover retains its patent portfolio intact. No court found any of the three asserted patents invalid, unenforceable, or not infringed. The voluntary exit may suggest a negotiated resolution — such as a license or commercial agreement — or a strategic decision to defer litigation, but neither is confirmed by the public record. Ice Rover’s ability to enforce these design and utility patents against TackLife or other market participants is legally unaffected by this dismissal.
Patent rights preservedTackLife avoids judgment but gains no formal IP clearance
TackLife did not obtain a declaration of non-infringement or invalidity. Without such a ruling, TackLife cannot cite this case as legal precedent to defeat future infringement claims based on the same patents. Competitors and other cooler manufacturers in the rotomolded segment face a similar exposure: the patents remain in force, and the dismissal provides no FTO cover. TackLife’s commercial risk from these three patents is only resolved if a separate license or covenant not to sue was negotiated privately.

Official order — verbatim text
The dismissal was filed by Ice Rover under Fed. R. Civ. P. 41(a)(1)(A)(i), which permits unilateral plaintiff dismissal before the defendant has answered. The without-prejudice designation is legally significant: it confirms no adjudication on the merits of infringement or validity for any of the three asserted patents. TackLife receives no res judicata protection from this proceeding. The phrasing ‘Stipulated Dismissal’ in the filing title is noted, though Rule 41(a)(1)(A)(i) technically requires no defendant stipulation at the pre-answer stage — this characterisation in the public record does not alter the legal effect of the dismissal.
USD893979S, US10272934B2 & USD881673S — portable cooler design and utility claims
The asserted portfolio combines three distinct intellectual property instruments. USD893979S and USD881673S are design patents protecting the ornamental appearance of portable cooler products — they cover how the product looks, not how it functions. US10272934B2 is a utility patent covering functional aspects of a portable cooler, filed as application US15/625092. Together, the trio creates overlapping protection: competitors must navigate both the aesthetic and functional dimensions of the patented cooler design, a layered enforcement strategy common in high-competition consumer goods categories.
The rotomolded cooler segment has become increasingly contested as premium brands like YETI have demonstrated the commercial value of durable, wheeled portable coolers. Ice Rover’s three-patent stack suggests a deliberate effort to establish IP barriers across multiple vectors — design and utility — making it harder for lower-cost competitors to introduce visually or functionally similar products without triggering infringement risk. For sector participants, the continued enforceability of these patents post-dismissal means the competitive risk profile for cooler manufacturers remains elevated.
Should your product team run an FTO against USD893979S, US10272934B2, and USD881673S?
Any company developing, importing, or selling portable hard-sided coolers — particularly wheeled rotomolded models in the 40–60 quart class — should treat this patent trio as active enforcement risk. Ice Rover’s willingness to pursue 827 days of litigation in the Western District of Texas signals genuine enforcement intent. The without-prejudice dismissal provides no safe harbour for TackLife or any other market participant. R&D and product teams should assess both the visual design elements covered by the two design patents and the functional claims of US10272934B2 before launching or refreshing product lines in this category.

What this case signals for the portable cooler and outdoor products IP landscape
Three asserted patents, 827 days, and a quiet exit: this case raises important questions for cooler brands operating in the rotomolded segment.
Design patents are potent offensive tools in consumer products litigation
Ice Rover deployed two design patents (USD893979S, USD881673S) alongside a utility patent, a combination increasingly common in consumer goods IP enforcement. Design patents allow visual comparisons that can be compelling to juries and are harder to design around than utility claims. Brands in the portable cooler category should audit whether their product aesthetics could be challenged under existing design registrations.
Dismissal without prejudice leaves the competitive landscape unsettled
No merits ruling means TackLife — and any similarly positioned competitor — cannot rely on this case for FTO purposes. Ice Rover’s patents remain enforceable. For brands selling rotomolded or hard-sided portable coolers with wheeled configurations, monitoring Ice Rover’s patent portfolio and any new filings is a commercially prudent step.
Ice v TackLife — key questions answered
Ice Rover filed a patent infringement action against TackLife in the Western District of Texas on July 19, 2022, asserting three patents — USD893979S, US10272934B2, and USD881673S — over TackLife’s Reyleo 50-Quart Portable Rotomolded Cooler. The case was dismissed without prejudice on October 23, 2024 under Fed. R. Civ. P. 41(a)(1)(A)(i), after 827 days of litigation. No merits ruling was issued.
Ice Rover asserted three patents: USD893979S (a design patent covering the ornamental appearance of a portable cooler), USD881673S (a second design patent for a portable hard-sided cooler), and US10272934B2 (a utility patent covering functional aspects of a portable wheeled cooler, from application US15/625092). The combination of design and utility patents creates layered infringement exposure for competitors in the rotomolded cooler market.
A dismissal without prejudice means no judgment was entered on the merits. TackLife did not obtain a ruling of non-infringement or invalidity. Ice Rover retains the legal right to refile claims based on the same patents against TackLife or other parties, subject to statutes of limitations. This dismissal provides no freedom-to-operate cover for TackLife or competing cooler brands. The enforceability of all three asserted patents is legally unchanged.
Fed. R. Civ. P. 41(a)(1)(A)(i) permits a plaintiff to dismiss without court order before the opposing party serves an answer or a motion for summary judgment. The absence of defendant counsel on record for TackLife in the case data is consistent with no answer having been filed, which would preserve Ice Rover’s right to use this mechanism regardless of how much time had elapsed since filing.
The case signals that Ice Rover is an active patent enforcer in the portable cooler space with a portfolio spanning both design and utility protection. The without-prejudice dismissal means the patents remain live enforcement tools. Companies manufacturing or selling rotomolded wheeled coolers should conduct FTO analysis against USD893979S, US10272934B2, and USD881673S, and monitor Ice Rover’s patent portfolio for new filings or continuation applications that could extend claim coverage.
