Mathews Archery v. Viper Sights: Consent Judgment, $21,001 Award & Permanent Injunction
Mathews Archery, Inc. asserted three design patents covering archery stabilizer aesthetics against Viper Sights’ Dovetail Riser Stabilizer line. The Western District of Pennsylvania closed the case after 171 days via a stipulated consent judgment — awarding Mathews $21,001 and permanently enjoining Viper from making, selling, or importing the accused products.
Design patent consent judgment shuts down Viper’s stabilizer line
Filed on 31 December 2024 in the Western District of Pennsylvania before Judge Mark R. Hornak, this infringement action was brought by Mathews Archery, Inc. — owner of three U.S. design patents (USD1,049,293, USD1,049,294, and USD1,049,295) — against Viper Sights, Inc., doing business as Viper Archery Products. The dispute centred on Viper’s Dovetail Riser Stabilizer products, offered in 8-, 10-, and 12-inch variants, which Mathews alleged infringed the ornamental design protected by its patents.
The case resolved on 20 June 2025 via a stipulated consent judgment, triggered by Viper’s Rule 68 offer of judgment dated 2 June 2025. Under the agreed terms, judgment of $21,001 was entered against Viper in favour of Mathews, payable directly to Baker Botts LLP within seven days. Critically, the Enjoined Parties — including Viper’s affiliates, successors, and any entity acting in concert — are permanently restrained from making, using, selling, offering for sale, or importing the Dovetail Riser Stabilizers or any colorable variation. Viper’s non-infringement counterclaims were dismissed with prejudice; remaining affirmative defenses were dismissed without prejudice.
Resolution within 171 days suggests Viper assessed continued litigation risk — including a potential permanent injunction at trial — as commercially unacceptable relative to the $21,001 settlement figure. The consent judgment’s broad injunction language, covering ‘colorable variations’ and all affiliates, indicates Mathews prioritised market exclusivity over damages quantum. What remains unknown from the public record is whether any confidential commercial terms accompanied the stipulation, and whether Mathews intends to pursue similar actions against other competitors in the archery accessories segment.

Consent judgment terms: what the $21,001 award and injunction mean
Consent judgment via Rule 68 offer: what it means
A stipulated consent judgment differs from a litigated verdict: both parties agree on terms and ask the court to enter judgment. Here, Viper made a Rule 68 offer of judgment on 2 June 2025 — a procedural device that, once accepted, caps cost exposure. The result is a court-entered, enforceable judgment without findings of fact or conclusions of law. Both parties waived appeal rights, making this disposition final and immediately binding.
Final, non-appealable judgmentMathews secures injunction and monetary award
Mathews Archery achieved its primary commercial objective: a permanent injunction that bars Viper and all affiliated entities from producing or selling the Dovetail Riser Stabilizers or any ‘colorable variation.’ The $21,001 monetary award is modest relative to typical patent litigation costs, but the broad injunctive relief — covering successors, assigns, and concert parties — suggests Mathews valued market protection over damages recovery. Viper’s non-infringement counterclaims were dismissed with prejudice, foreclosing that route of future challenge.
Permanent injunction grantedViper exits the accused product line under court order
Viper Sights accepted a $21,001 judgment and a binding permanent injunction, effectively withdrawing its Dovetail Riser Stabilizer products from the market. While the consent judgment limits ongoing litigation cost, the injunction’s ‘colorable variation’ language constrains Viper’s ability to redesign and re-enter the same product space without risking contempt proceedings. The dismissal of non-infringement counterclaims with prejudice forecloses re-litigating those specific defenses. Remaining affirmative defenses were dismissed without prejudice, preserving limited future flexibility.
Product line permanently enjoinedDesign patent enforcement signals risk for archery accessories market
This outcome demonstrates that design patent holders in the archery accessories segment are willing to assert ornamental design rights aggressively — and can secure both injunctions and monetary relief within six months of filing. Competitors offering stabilizer products with similar visual configurations face meaningful infringement exposure. The ‘colorable variation’ scope of the injunction reinforces that design-arounds must go beyond superficial modifications. Brands operating in the archery stabilizer category should conduct proactive FTO analysis against Mathews’ design patent portfolio.

Official order — verbatim text
The stipulated consent judgment is precise in its enforcement architecture: it enters a $21,001 money judgment while simultaneously imposing a permanent injunction covering ‘colorable variations’ — a formulation that goes beyond the specific accused products listed in the amended complaint. Viper’s non-infringement counterclaims are dismissed with prejudice, eliminating those defenses in any future related proceeding, while remaining affirmative defenses are preserved without prejudice. The mutual waiver of appeal rights renders this judgment immediately final, consistent with a negotiated resolution rather than a litigated outcome.
USD1,049,293, USD1,049,294 & USD1,049,295 — archery stabilizer ornamental design patents
USD1,049,293, USD1,049,294, and USD1,049,295 are U.S. design patents owned by Mathews Archery, Inc., all sharing priority through applications US29/882,262, US29/882,287, and US29/882,289 respectively. Design patents protect the ornamental — not functional — appearance of a product, meaning the visual configuration of the stabilizer unit itself is the protected subject matter. Filing three related design patents on a single product category is a deliberate portfolio strategy: each patent captures a distinct ornamental variation, together creating overlapping design protection that is structurally difficult for competitors to circumvent with minor aesthetic modifications.
For the archery accessories sector, Mathews’ design patent family around stabilizer products represents a meaningful competitive moat. Stabilizer aesthetics are commercially significant in the hunting and competitive archery markets, where product appearance influences purchasing decisions. A portfolio covering multiple ornamental variants means that even a substantive redesign of a competing stabilizer may fall within the scope of one of the three patents. Any manufacturer or brand entering the archery stabilizer space — particularly dovetail riser configurations — should conduct detailed FTO analysis against this patent family before product launch.
Should you run an FTO against USD1,049,293, USD1,049,294 & USD1,049,295?
Any company designing, manufacturing, or importing archery stabilizers — particularly riser-mount or dovetail-style configurations — should treat Mathews’ three-patent design family as a primary FTO priority. The consent judgment’s ‘colorable variation’ injunction language signals that courts will apply broad design patent scope in this product category. OEM suppliers, private-label brands, and retailers sourcing archery accessories from third-party manufacturers all carry potential downstream infringement exposure.
PatSnap Eureka’s FTO Search Agent can analyse the visual claim scope of USD1,049,293, USD1,049,294, and USD1,049,295 against your proposed stabilizer designs — mapping ornamental similarities and identifying design-around opportunities before product launch.

Portfolio viewWhat this case signals for the archery accessories IP landscape
A swift consent judgment with a broad permanent injunction shows design patents carry real enforcement teeth in the sporting goods segment.
Speed of resolution reflects defendant’s commercial risk calculus
Viper’s decision to offer judgment after just 154 days of litigation — before any claim construction or summary judgment — suggests an internal assessment that the ornamental designs were sufficiently distinctive to sustain Mathews’ infringement claims. Competitors should treat rapid consent judgments as signals of strong design patent validity, not merely weak defendant finances.
Permanent injunction scope is the operative commercial outcome
The $21,001 award is commercially secondary to the permanent injunction binding Viper, all affiliates, successors, and concert parties. Any archery accessories company considering product acquisitions involving Viper or related entities must conduct due diligence on this judgment’s binding scope before completing a transaction.
Mathews’ three-patent design family creates layered enforcement risk
Filing three design patents on a single product family — each capturing related but distinct ornamental elements — creates overlapping coverage that is difficult to design around. Competitors attempting to modify stabilizer aesthetics to avoid one patent may inadvertently infringe the others. PatSnap Eureka can map the claim scope of all three patents to identify clearance zones.
Rule 68 offer timing reveals settlement leverage windows
Viper’s Rule 68 offer came 154 days post-filing, likely after initial discovery exchanges revealed unfavourable infringement evidence. Monitoring the docket cadence in similar design patent cases can help IP teams anticipate when defendants are likely to seek early resolution — a key input for licensing strategy and enforcement sequencing.
MATHEWS v VIPER — key questions answered
The case closed on 20 June 2025 via a stipulated consent judgment. Viper Sights agreed to a $21,001 money judgment in favour of Mathews Archery and accepted a permanent injunction prohibiting it from making, selling, or importing the Dovetail Riser Stabilizer products or any colorable variation. Both parties waived appeal rights and agreed to bear their own attorneys’ fees.
Mathews Archery asserted three U.S. design patents: USD1,049,293, USD1,049,294, and USD1,049,295 — collectively referred to in the judgment as the ‘Mathews Patents.’ These design patents protect the ornamental appearance of archery stabilizer products, with priority applications US29/882,262, US29/882,287, and US29/882,289. The patents cover any continuations, divisionals, reissues, reexaminations, and foreign counterparts.
The accused products were Viper Sights’ Dovetail Riser Stabilizer products, sold in 8-inch, 10-inch, and 12-inch models, as identified in Mathews’ Amended Complaint (ECF No. 16). These products are referred to in the consent judgment as ‘Viper Enjoined Products’ and are permanently enjoined along with any colorable variations thereof.
The permanent injunction binds the ‘Enjoined Parties’ — defined broadly as Viper Sights, all affiliates, predecessors, successors, assigns, and any person or entity acting in concert with them. It permanently restrains those parties from directly or indirectly making, using, selling, offering for sale, or importing the Dovetail Riser Stabilizers or any colorable variation. The court retains jurisdiction to enforce compliance.
Yes, partially. Viper’s affirmative defenses and counterclaims of non-infringement were dismissed with prejudice under the consent judgment, meaning they cannot be relitigated in future proceedings related to the same patents and products. Viper’s remaining affirmative defenses and counterclaims raised in its Answer to Amended Complaint (ECF No. 41) were dismissed without prejudice, preserving limited future flexibility on those issues.
