Narrative Opinion Summary
This case involves Berry Sterling Corporation's appeal of a U.S. District Court decision that granted summary judgment to Pescor Plastics, Inc., thus invalidating Berry's U.S. Patent Des. No. 362,368. The patent covered an ornamental design for a container developed for Coca Cola's 'Coke to Go' initiative, which required specific functional attributes. The district court ruled that the design was primarily dictated by functionality, without addressing claims of obviousness or infringement. On appeal, the court vacated the judgment and remanded the case, finding that the district court had improperly applied summary judgment standards by not fully considering the patent's claimed ornamental appearance and the existence of alternative designs. The appellate court stressed that a proper patent analysis must focus on the design's claimed appearance rather than its commercial embodiments and recognized that the presence of multiple design options indicates an ornamental purpose. The decision was vacated for further proceedings to appropriately assess whether the design claim was invalid due to functionality.
