Narrative Opinion Summary
The case involves a patent infringement dispute between The Nautilus Group, Inc. and ICON Health & Fitness, Inc., centered on U.S. Patent No. 4,725,057, which covers the BowFlex® exercise machine. Nautilus alleged that ICON's CrossBow® infringed on this patent. The district court ruled in favor of ICON, finding no literal infringement, primarily due to differences in the structural design of the rods used in the machines. It interpreted the term 'cantilevered fashion' in claim 12 to require rods with fixed ends, based on dictionary definitions. However, the higher court questioned this interpretation, emphasizing that claims should reflect broader definitions unless explicitly limited, and noted the district court's reliance on extrinsic evidence rather than the intrinsic record. The court highlighted that claim differentiation suggested claim 12 could accommodate rods with either one or both ends free. Consequently, the appellate court remanded the case to the district court to reconsider its interpretation, instructing a broader understanding of 'cantilevered' that aligns with the patent's intent, thus potentially altering the initial non-infringement ruling.
