Major privately held food and agribusiness company based in the U.S., a prominent supplier of frozen potato products.

- • USD0640036S — Design patent protecting the ornamental appearance of a twisted potato product.

Das Urteil und die rechtliche Analyse
Ergebnis
The Federal Circuit **affirmed** the infringement judgment in favor of McCain Foods Ltd. The court’s order confirms that J.R. Simplot Co. infringed both the utility patent (US6821540B2) and the design patent (USD0640036S) as asserted by McCain. This affirmance signals that McCain Foods’ intellectual property protections over its potato product technology remain intact.
Wichtige rechtliche Fragen
The Federal Circuit’s affirmance of an infringement finding typically means the appellate panel found no reversible error in the district court’s claim construction, infringement analysis, or validity assessment. For the design patent claims (USD0640036S), the operative test is the “ordinary observer” standard — whether an ordinary observer would find the accused product substantially similar to the patented design. The Federal Circuit’s affirmance suggests McCain’s twisted potato design was sufficiently distinctive and that Simplot’s product crossed into protected ornamental territory.

Two patents were at issue: utility patent US6821540B2, covering twisted potato product technology, and design patent USD0640036S, protecting the ornamental appearance of the product.
The Federal Circuit affirmed the lower court’s infringement judgment in favor of McCain Foods Ltd., confirming that J.R. Simplot Co. infringed both asserted patents.
It validates dual utility-design patent enforcement in food technology and signals that well-constructed infringement cases will withstand Federal Circuit scrutiny, encouraging similar assertion strategies.
