Blackstrap Industries v. Rockbros USA: Design Patent Dispute Ends in Agreed Dismissal
Blackstrap Industries filed suit in the District of New Jersey alleging Rockbros USA infringed design patent USD758703S covering its flagship balaclava design. After 524 days of litigation, both parties agreed to dismiss all claims with prejudice — with no costs or attorneys’ fees awarded to either side.
Design Patent War Over Balaclavas Settles on Agreed Terms
Blackstrap Industries, Inc., a balaclava and headwear brand, filed this infringement action on 28 June 2024 in the U.S. District Court for the District of New Jersey against Rockbros USA LLC, a competing headwear retailer. The dispute centred on design patent USD758703S (application no. US29/453183), which protects the ornamental appearance of Blackstrap’s flagship balaclava product. Blackstrap alleged that Rockbros’s competing balaclavas infringed that protected design.
The case closed on 4 December 2025 via a joint stipulation filed under Federal Rule of Civil Procedure 41. Under the agreed order, all claims, counterclaims, and affirmative defences were dismissed with prejudice — meaning neither party may re-litigate the same claims in federal court. Notably, the stipulation contains no award of costs or attorneys’ fees to either side, suggesting a negotiated resolution rather than a clear-cut win for either party.
The 524-day duration before a stipulated dismissal suggests meaningful settlement negotiations occurred after substantive litigation activity, though the public record does not disclose any underlying licensing agreement or financial terms. The court’s retained jurisdiction clause — preserving the District of New Jersey’s authority to resolve future disputes over the subject matter — is consistent with a private settlement agreement operating alongside the dismissal, though the existence or terms of any such agreement remain unknown from the docket.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41 stipulated dismissal with prejudice explained
Under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), parties may jointly stipulate to dismiss an action. A dismissal ‘with prejudice’ is a final adjudication on the merits — it permanently bars either party from refiling the same claims. This is the most legally conclusive form of voluntary dismissal and is typically the product of a negotiated resolution between the parties.
Permanent bar on refilingBlackstrap cannot re-assert these infringement claims
A with-prejudice dismissal extinguishes Blackstrap’s infringement claims against Rockbros for the conduct at issue. Blackstrap may not revive this specific action. However, USD758703S remains a valid, enforceable design patent — Blackstrap retains full rights to assert it against other parties or in response to future infringing conduct by Rockbros that post-dates any settlement terms.
Patent validity preservedRockbros secures closure but faces ongoing design risk
Rockbros obtains finality against Blackstrap’s current claims and cannot be re-sued on the same accused conduct. The absence of any costs award suggests neither party was found to have litigated in bad faith. However, if Rockbros continues selling balaclava designs that overlap with USD758703S, it remains exposed to fresh infringement actions absent a licence or design-around.
No costs; future risk remainsDesign patent enforcement in outdoor headwear: key takeaways
This case signals that design patent holders in the performance headwear segment are willing to litigate to protect ornamental differentiation — but are also prepared to resolve disputes commercially. For competitors sourcing or manufacturing balaclavas, USD758703S remains an active enforcement risk. A freedom-to-operate review against this patent is advisable before launching competing products in the U.S. market.

Official order — verbatim text
The stipulation is precise in its finality: all claims, counterclaims, and affirmative defences are dismissed with prejudice, and no costs or fees are awarded. The with-prejudice standard forecloses any future refiling on these facts. The express retention of court jurisdiction is legally significant — it transforms the court into an enforcement mechanism for any underlying private agreement, without requiring that agreement to be placed on the public record. Neither the verdict text nor the docket discloses financial terms.
USD758703S — Ornamental design for a balaclava headwear product
USD758703S (application no. US29/453183) is a U.S. design patent protecting the ornamental appearance of a balaclava — a close-fitting headwear garment covering the head, neck, and face, widely used in cold-weather outdoor and performance sports applications. Design patents under 35 U.S.C. § 171 protect the distinct visual characteristics of a product, not its functional attributes. The scope of protection is defined by the drawings and is assessed under the ‘ordinary observer’ test established in Egyptian Goddess v. Swisa.
For the performance headwear sector, design patents like USD758703S represent a meaningful competitive moat. Blackstrap’s flagship balaclava has a recognisable aesthetic that contributes to brand identity and consumer recognition. Competitors — particularly those sourcing similar-looking products from overseas manufacturers — face meaningful infringement risk if the ornamental profile of their products would deceive an ordinary observer into believing they are the patented design. This case demonstrates that Blackstrap is prepared to enforce that moat through litigation.
Should you run an FTO analysis against USD758703S?
Any brand, retailer, or importer selling balaclavas or similar close-fitting face-and-head coverings in the U.S. market should treat USD758703S as a clearance priority. The ‘ordinary observer’ standard for design patent infringement is broad — even non-identical products can infringe if a consumer would mistake them for the patented design. This is particularly relevant for companies sourcing private-label or OEM headwear from manufacturers who supply multiple buyers with similar silhouettes.
PatSnap Eureka’s FTO Search Agent allows R&D and product teams to run systematic design patent clearance searches against USD758703S and the broader Blackstrap design portfolio. The tool surfaces similar design patents by visual and structural similarity, maps the claim scope, and flags overlap with your product’s ornamental features — enabling informed go/no-go decisions before you commit to inventory or launch campaigns.

What this case signals for the performance headwear IP landscape
A stipulated dismissal with prejudice after 524 days typically suggests a negotiated outcome. Here is what that means for the sector.
Design patents are real enforcement tools in the headwear category
Blackstrap’s willingness to litigate for over 17 months over a design patent signals that ornamental IP is being actively enforced in the outdoor/performance headwear segment. Brands that rely on distinctive product appearance should audit competitor lines against their own design portfolio — and vice versa.
Retained jurisdiction clause suggests a private settlement agreement
The stipulation expressly preserves the court’s jurisdiction to resolve future disputes over the subject matter. This language is a standard mechanism used when a confidential settlement agreement accompanies a dismissal — implying commercial terms, potentially including a licence or market boundary, may govern the parties’ ongoing relationship.
BLACKSTRAP v ROCKBROS — key questions answered
A dismissal with prejudice is a final, merits-equivalent resolution. In this case, it means Blackstrap Industries cannot refile its design patent infringement claims against Rockbros USA based on the same accused conduct. The joint stipulation under FRCP Rule 41 permanently extinguishes those specific claims, though USD758703S remains enforceable against other parties.
Yes. The dismissal with prejudice resolves only this specific dispute between Blackstrap and Rockbros. It does not invalidate or limit USD758703S. The patent remains active and enforceable by Blackstrap against any third party whose balaclava products infringe the ornamental design shown in the patent drawings.
The retention of jurisdiction clause — preserving the District of New Jersey’s authority to enforce and resolve disputes over the subject matter — is a standard mechanism used when a private settlement agreement accompanies a court dismissal. It allows either party to return to the court to enforce the settlement without filing a new lawsuit, suggesting a confidential agreement governs the parties’ ongoing relationship.
The ordinary observer test, from Egyptian Goddess, Inc. v. Swisa, Inc. (Fed. Cir. 2008), is the standard for design patent infringement. A product infringes a design patent if an ordinary observer, familiar with the prior art, would mistake the accused design for the patented design. For USD758703S, this means any balaclava with a sufficiently similar ornamental profile to Blackstrap’s patented design could potentially infringe — regardless of brand labelling.
Companies importing balaclavas — particularly those sourcing OEM or private-label products — face direct infringement exposure in the U.S. regardless of where manufacturing occurs. The U.S. importer or reseller is a proper defendant for design patent claims. This case suggests Blackstrap actively monitors the market. Importers should conduct design patent clearance against USD758703S and consider ITC Section 337 exposure, which allows exclusion orders blocking importation of infringing goods.
