Narrative Opinion Summary
In a case involving allegations of patent infringement and misappropriation of trade secrets in wallboard manufacturing, the plaintiff, United States Gypsum Company (USG), and the defendants, Lafarge North America, Inc., contest the admissibility of expert testimony under Federal Rule of Evidence 702 and the Daubert standard. The court examines motions to exclude testimony from USG's expert, Carl Florez, and the defendants' expert, Andrew Reisman. Florez's testimony focuses on USG's data protection measures and alleged wrongful acquisition of documents by the defendants, while Reisman critiques Florez's methodology. The court permits Florez to testify about data protection and whether defendants accessed trade secrets but restricts him from using the term 'misappropriate' or speculating on intent or spoliation. Similarly, Reisman may challenge Florez's methods but is barred from assumptions about the defendants' intent or document use. The court underscores the importance of expert qualifications and reliability, referencing industry standards and expertise in computer forensics. The ruling allows both experts to contribute factual insights while reserving determinations of intent for the jury, maintaining a balance between expert analysis and jury interpretation.
