In this patent infringement action, Stryker moved to strike the expert report of Karl Storz’ (“KSEA”) infringement expert because the expert did not provide any analysis of infringement of the patent-in-suit. As explained by the district court, Karl Storz’ infringement expert’s, Mr. Gould Bear, report included six sections: (1) introduction, (2) summary of conclusions, (3) background and qualifications, (4) materials reviewed, (5) legal principals and methods, and (6) conclusion.
The expert report did not provide any analysis regarding how “the accused products literally include each element of Claims 1, 2 and 3 of the ’420 Patent.” And the district court explained that “[e]ven Mr. Gould Bear’s description of his process is conclusory: ‘I have analyzed literal infringement with respect to each limitation of the asserted patent claim, comparing the accused products – in their ordinary and intended uses – to the invention described in the patent claim they are alleged to infringe. When analyzing a dependent claim, I determined whether the allegedly infringing products include each and every element of the dependent claim, the independent claim from which it depends and all intermediate dependent claims.’ (Id. at 14-15 ¶ 32.)
The expert report made no effort to explain how the expert determined that the allegedly infringing products include each element of the dependent claim and instead just stated he had made that determination.
