Chief Judge Stark grants Daubert motion

Chief Judge Leonard P. Stark recently ruled on Daubert motions in Greatbatch Ltd. v. AVX Corp., C.A. No. 13-723-LPS (D. Del. July 20, 2017).  Of note, the Court granted a Daubert motion to preclude an expert from testifying “that ‘no reasonable metallurgist’ would relay on certain data,” explaining that such testimony would “improperly usurp[] the Court’s gatekeeping function of determining reasonable reliance.”

The Court also granted-in-part a motion to preclude a plaintiff expert from testifying as to the defendant-employees’ state of mind and intent, explaining that “[s]uch statements are improper legal conclusions based on unscientific interpretation.”  The same expert also was precluded from offering an opinion that the defendant’s earlier products (as well as its current products) infringe, because the expert “offers no analysis to support this opinion and, to the contrary, acknowledged the difference the [earlier] primer could have.”
