Judge Gorton denied both parties’ motions to disqualify each other’s expert witnesses in a contentious litigation involving allegations of doctored evidence. LovePop asserts that PaperPop infringed its copyright in several designs of pop-up greeting cards. PaperPop produced documents and photographs that were alleged to show that PaperPop conceived of the designs first, but LovePop purports that PaperPop tampered with the metadata to falsely back-date the documents to the relevant date. LovePop proffered an expert who would testify as to what metadata was, the means for manipulating metadata, and that some of PaperPop’s documents could not have been created on the dates alleged because the software with which they were created had not yet been made available. PaperPop in turn proffered an expert to testify that LovePop’s expert used unvalidated testing to achieve his results and to present the results of his testing that show the tests of LovePop’s expert were unreliable and incorrect. Judge Gorton determined that both parties’ complaints were directed to the credibility of their opponents’ experts, who were otherwise both well-qualified. Accordingly, he denied both motions.
