Dastar Corp. v. Twentieth Century Fox Film Corp. in South Dakota Law

How Dastar Corp. v. Twentieth Century Fox Film Corp. applies in South Dakota: state-specific rules, key cases, and bar exam notes for Intellectual Property — Trademark (Lanham Act) / Unfair Competition.

State Approach

South Dakota follows similar principles established in Dastar Corp. v. Twentieth Century Fox Film Corp., particularly concerning the application of trademark laws and the standards for unfair competition. The state respects the idea that trademark protections do not extend to unprotected works or ideas that are not distinctly identified with a particular source.

State Rule
In South Dakota, trademark protection is governed by both state law and the Lanham Act, ensuring that marks that are not used or are generic cannot be protected under unfair competition principles.
Significant State Cases

SDH Acquisitions, Inc. v. W. Cargo, LLC

The court held that the plaintiff could not claim trademark protections due to lack of distinctiveness in the used mark.

Lozier v. Estates of the Black Hills, Inc.

The court ruled that unfair competition claims must show a recognizable misrepresentation associated with the trademark.

Hansen v. City of Sioux Falls

The case emphasized that the use of trademarks must be tied to explicit commercial acts, limiting protections under state law.

Comparison to Federal Law

South Dakota's approach aligns closely with the federal standard under the Lanham Act, particularly regarding marks that cannot claim protection. However, South Dakota's courts may apply stricter criteria to distinguish between generic terms and protected trademarks than some federal courts.
