Federal Circuit Decision Highlights Risks in Design Patent Filings Using Utility Application Priority


The U.S. Court of Appeals for the Federal Circuit rendered a decision in April 2025, shedding light on potential pitfalls for practitioners in the domain of design patent prosecution. A critical takeaway from the case of Floyd is the potential risk involved when attempting to claim priority from a utility application to a design patent.

John Hemmer of Morgan Lewis emphasizes the legal implications surrounding this prosecutorial strategy following the court’s ruling, advising legal professionals to exercise caution when navigating these terrains. The ruling illustrates the nuanced differences between utility and design patents—differences that, if not properly considered, could result in unenforceable design rights based on filing inaccuracies.
