Case Brief Summary & Legal Analysis
tl;dr: A clog manufacturer’s design patents were invalidated based on prior art. The appellate court reinstated the patents for further review, holding that the “ordinary observer” test is the sole test for anticipation and requires comparing the entire design, including features like insoles visible at the point of sale.
Legal Significance: This case established that the “ordinary observer” test is the sole standard for design patent anticipation under 35 U.S.C. § 102, eliminating the “point of novelty” test and aligning the standard for validity with the standard for infringement established in Egyptian Goddess.

Case Facts & Court Holding
Key Facts & Case Background
International Seaway Trading Corp. (“Seaway”) owned three design patents for clogs. Seaway sued Walgreens Corp. for infringement. Walgreens moved for summary judgment, arguing Seaway’s patents were invalid as anticipated by a prior art design patent for Crocs-brand clogs (the ’789 patent). The overall exterior appearances of the Seaway and Crocs clogs were very similar, with minor variations in the number and placement of ventilation holes. However, the patented design featured a distinct pattern of dimples on the insole, which differed from the insole pattern in the prior art. The district court granted summary judgment of invalidity. In its analysis, the court applied only the “ordinary observer” test and refused to compare the insoles of the competing designs. The court reasoned that insoles are not visible during the “normal use” of a shoe (i.e., when worn on a foot), and therefore were irrelevant to the anticipation analysis. Seaway appealed, arguing the court should have also applied the “point of novelty” test and erred by excluding the insoles from its comparison.
Court Holding & Legal Precedent
Issue: Is a design patent anticipated under 35 U.S.C. § 102 if an ordinary observer, comparing the patented design and the prior art reference as a whole, would find them substantially the same, and must this comparison include ornamental features visible during any part of the product’s normal life, including at the point of sale?
Yes. The “ordinary observer” test is the sole test for design patent Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Legal Issue
Is a design patent anticipated under 35 U.S.C. § 102 if an ordinary observer, comparing the patented design and the prior art reference as a whole, would find them substantially the same, and must this comparison include ornamental features visible during any part of the product’s normal life, including at the point of sale?
