Narrative Opinion Summary
Datamize, L.L.C. appealed a decision from the United States District Court for the Northern District of California, which invalidated all claims of U.S. Patent No. 6,014,137 for indefiniteness under 35 U.S.C. § 112, ¶ 2. The patent, concerning an authoring system for electronic kiosk interfaces, was challenged by Plumtree Software, Inc., which argued that the term 'aesthetically pleasing' was indefinite. The district court concurred, emphasizing the lack of an objective standard for this term. Datamize contended that the term should be interpreted subjectively, aligning with the intent of the system creator. However, the court found this argument unconvincing, noting the necessity for an objective measure to ensure public notice of the patentee's rights. The appellate court, reviewing the grant of summary judgment de novo, upheld the lower court's decision, affirming the patent's invalidity. The ruling underscores the importance of precise claim language and the statutory requirement for definiteness, rejecting subjective interpretations that lack a clear standard. Consequently, Datamize's patent claims were invalidated, leaving them without recourse in this infringement dispute.

Application: The court analyzed whether the phrase 'aesthetically pleasing' could be given a reasonable meaning based on intrinsic and extrinsic evidence, ultimately finding it indefinite.
Reasoning: The determination of definiteness is based on whether terms can be given reasonable meaning, and challenging claim construction does not automatically imply indefiniteness.

Reasoning: The district court found no explicit definition in the patent’s specification that would limit this subjectivity. Ultimately, the court deemed 'aesthetically pleasing' to be 'hopelessly indefinite,' granting Plumtree’s motion for summary judgment of invalidity.
