Challenge to Printed Publication Status of Prior Art Reference Does Not Justify Late Disclosure of New Reference​

The court granted plaintiff's motion to strike a previously undisclosed prior art publication from defendant's invalidity contentions and rejected defendant's argument that the reference was necessary to address plaintiff's challenge to another reference. "[W]hile it is true that the printed publication argument was raised only in response to [defendant's] motion for summary judgment of anticipation, [defendant] should not have been caught entirely unawares by [plaintiff's] printed publication defense to [defendant's] reliance on the [originally disclosed] reference as anticipating prior art. Given the obscurity of the [original] reference, it is not surprising that [plaintiff] would raise an issue as to whether the [original] publication was sufficiently in the public domain to qualify as prior art. . . . Nothing prevented [defendant] from citing both [the original] and the [new] reference in its original invalidity contentions. . . . [I]t would be highly prejudicial to [plaintiff] for [defendant] to be allowed to use the [new] reference after having raised it for the first time only a few weeks before trial and after the close of discovery."
