The U.S. Court of Appeals upheld a PTAB ruling declaring Xerox's patent unpatentable due to obviousness, despite some disagreement over the Board's claim construction analysis. The case revolved around Snap's challenge to claims of Xerox's patent regarding user context sharing technology via mobile devices. The court clarified that the term 'context graph' must include inherent graph-based features, rejecting Xerox's argument that these properties should not be specifically required in the patent's definitions and affirming that claim interpretations must adhere to their original intent.
The term 'context graph' must maintain its core meaning, emphasizing that patent claims cannot be stretched to encompass unrelated conceptsâsimilar to not redefining a bicycle.
Xerox argued against the PTAB's claim construction that excluded specific graph-based properties, while the CAFC affirmed the need for inherent graph characteristics in the patent.
