Ridge Wallet v. Bemmo — Court Denies Dismissal of Patent and Trade Dress Claims Over Compact Wallet Design

Background

Ridge Wallet — maker of the popular slim, minimalist wallet — sued Bemmo Inc. for patent and trade dress infringement. Ridge Wallet holds U.S. Patent No. 10,791,808, covering a compact wallet design with specific structural features including an auxiliary mechanism (a removable hook or tang engaging a recess). Ridge Wallet also claimed trade dress protection for its distinctive “Forged Ember” design — a unique pattern of irregularly-shaped geometric red speckling on a carbon fiber surface in shades of grey and black.

Bemmo moved to dismiss all claims under Rule 12(b)(6), arguing that its Slim Wallet does not meet the patent’s claim limitations and that Ridge Wallet’s trade dress claims were inadequately pleaded.

The Court’s Holding

Judge Komitee denied Bemmo’s motion to dismiss in its entirety.

On direct patent infringement: Bemmo argued the Slim Wallet lacks the patent’s “Auxiliary Feature Limitation” (a removable hook/tang/recess mechanism) and “Recess Limitation.” The court held these arguments premature — resolving them would require claim construction without a Markman hearing, expert testimony, or discovery. Ridge Wallet’s interpretation that the Slim Wallet’s money clip bends at an angle to form a “hook” engaging a recess was “at least plausible” and sufficient at the pleading stage.

On induced and contributory infringement: Ridge Wallet adequately pled scienter by alleging it sent Amazon takedown requests in January 2023 and a cease-and-desist letter in February 2023 specifically accusing Bemmo of infringing the ‘808 Patent. The court found Bemmo’s asserted good-faith belief in non-infringement “presents a factual question” not suitable for resolution at the motion to dismiss stage.

On trade dress: The court found Ridge Wallet adequately pled all four elements of its trade dress claim for the Forged Ember design. The design was precisely articulated (a specific combination of materials, patterns, and colors), secondary meaning was supported by allegations of millions in advertising and substantial sales, non-functionality was established because the decorative pattern is ornamental (Ridge Wallet sells other wallets without it), and likelihood of confusion was plausible given both products compete in the same online compact wallet market.

Key Takeaways

• Claim construction at the pleading stage is an uphill battle. Courts generally will not resolve competing claim interpretations on a motion to dismiss — defendants must wait for a Markman hearing and discovery to challenge whether a product meets claim limitations.
• Cease-and-desist letters establish scienter for induced infringement. Sending a detailed letter accusing a competitor of specific patent infringement, followed by continued sales, can satisfy the knowledge element for induced and willful infringement claims.
• Consumer product trade dress is protectable when precisely defined. Ridge Wallet’s success in surviving dismissal turned on its precise articulation of the protected design elements and strong allegations of secondary meaning through advertising spend and media coverage.

Why It Matters

For consumer product companies, this ruling reinforces that both utility patents and trade dress can provide meaningful protection against knockoff competitors — and that these claims are difficult to defeat at the motion to dismiss stage. The decision is particularly relevant for the growing market of direct-to-consumer brands that sell distinctive products primarily through Amazon and other online marketplaces, where copycat products proliferate. The court’s approach to trade dress secondary meaning — crediting allegations of advertising investment, media coverage, and active enforcement — provides a useful template for brands seeking to protect their distinctive designs.
