Case Brief Summary & Legal Analysis
tl;dr: A patent claim for a software system requiring an “aesthetically pleasing” user interface was held invalid. The court found the term purely subjective and lacking any objective standard, making the claim’s scope impossible for the public to determine.
Legal Significance: Establishes that purely subjective claim terms, such as “aesthetically pleasing,” render a utility patent claim indefinite under 35 U.S.C. § 112 unless the patent provides an objective standard for measuring the term, thereby providing an “objective anchor.”
Case Facts & Court Holding
Key Facts & Case Background
Datamize, LLC owned U.S. Patent No. 6,014,137, which claimed a software system for authoring user interfaces for electronic kiosks. The patent’s sole independent claim required the system to generate a “uniform and aesthetically pleasing look and feel” for the interface screens. Datamize sued Plumtree Software, Inc. for infringement. Plumtree moved for summary judgment, arguing the patent was invalid for indefiniteness under 35 U.S.C. § 112, ¶ 2. Plumtree contended that the term “aesthetically pleasing” is entirely subjective and that the patent’s specification provided no objective guidance or standard to determine its meaning. The specification mentioned that design choices could be based on the “considered opinions of aesthetic design specialists” but did not define what those opinions were. The district court granted summary judgment, finding the term “hopelessly indefinite.” Datamize appealed, arguing that the term was not fatally imprecise and should be evaluated from the subjective viewpoint of the person practicing the invention.
Court Holding & Legal Precedent
Issue: Does a patent claim term that relies on a purely subjective aesthetic judgment, such as “aesthetically pleasing,” without an objective standard provided in the patent’s specification, render the claim invalid for indefiniteness under 35 U.S.C. § 112, ¶ 2?
Yes. The Federal Circuit affirmed the district court’s summary judgment of invalidity, Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore
