Case Overview
The Parties
⚖️ Plaintiff
A consumer products intellectual property holding entity with a focus on asserting design and utility patent rights in juvenile and household product categories.
🛡️ Defendant
Globally recognized biopharmaceutical company. The actual dismissal notice named Regalo International, LLC, suggesting a potential clerical or docketing discrepancy in the original filing.
The Patent at Issue
The asserted patent, **USD852543S** (corrected application number: **US29/685,495**), is a design patent protecting the ornamental appearance of a product in the juvenile sleep/travel product category. Design patents, governed under 35 U.S.C. § 171, protect the unique visual characteristics of a manufactured article rather than its functional attributes.

The Verdict & Legal Analysis
Outcome
The case was resolved via **voluntary dismissal without prejudice**, filed by Keezio Group, LLC pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). No damages were awarded. No injunctive relief was granted. The dismissal without prejudice preserves the plaintiff’s right to refile the same claims in the future, subject to applicable statutes of limitations and any potential Rule 11 considerations.
Key Legal Issues
The most analytically significant element of this case is the apparent mismatch between the **named defendant (Regeneron Pharmaceuticals, Inc.)** and the **party identified in the dismissal notice (Regalo International, LLC)**. This discrepancy highlights the critical importance of accurate defendant identification in patent assertion strategy. Such errors can expose plaintiffs to Fed. R. Civ. P. Rule 11 sanctions if not promptly corrected. The rapid dismissal suggests plaintiff’s counsel moved quickly once the issue was identified, before any responsive pleading was filed.
