Case Overview
The Parties
⚖️ Plaintiff
Individual patent holder asserting rights over the ornamental design of an Inflatable Flamingo Floater.
🛡️ Defendant
Named as the accused infringer, alleged to have manufactured, distributed, or sold a product that infringed upon the protected ornamental design.
The Patent at Issue
The patent central to this dispute is U.S. Design Patent USD858674S (Application No. US29/656568), protecting the ornamental design of an Inflatable Flamingo Floater. Design patents protect the ornamental or aesthetic appearance of a functional article — not its utility.
Under the “ordinary observer test,” infringement is evaluated based on whether an ordinary observer, familiar with the prior art, would be deceived into believing the accused design is the same as the patented design.

Litigation Timeline & Procedural History
The complaint was filed on December 11, 2024 in the U.S. District Court for the Western District of Pennsylvania, and assigned to Chief Judge Cathy Bissoon. The case closed administratively on May 28, 2025, following confirmation of a settlement agreement.
| Complaint Filed | December 11, 2024 |
| Case Closed (Settlement) | May 28, 2025 |
| Total Duration | 168 days |
This 168-day duration from filing to administrative closure is notably swift for patent litigation, highlighting the pragmatic approach of both parties in resolving a consumer goods dispute before peak seasonal sales cycles.
The Verdict & Legal Analysis
Outcome
On May 28, 2025, Judge Cathy Bissoon entered an Order for Administrative Closing, confirming the parties had settled. The court retained jurisdiction to enforce the settlement agreement.
Specific damages amounts, royalty terms, or injunctive relief provisions were not disclosed in the public record, a common feature of privately negotiated design patent settlements.
Legal Significance
While this case does not produce a published opinion and therefore carries no direct precedential value, it contributes to the observable pattern of design patent enforcement in consumer goods — particularly in seasonal recreational products where short market windows make rapid resolution strategically preferable.
The swift resolution may suggest that the infringement case, evaluated under the “ordinary observer test,” was commercially clear enough that prolonged litigation was not economically rational for the defendant. This case also reflects the continuing viability of individual inventor enforcement of design patents.
