Bone Care Int’l, LLC v. Pentech Pharm. Inc., No. 08 C 1083, Slip Op. (N.D. Ill. Jul. 16, 2010) (Ashman, Mag. J.).

Judge Ashman granted plaintiffs’ motion to strike defendants’ expert affidavit (the "Affidavit") in this patent case. The Affidavit was filed in support of defendants’ Daubert motion filed after the close of fact discovery. The Court struck the Affidavit for three reasons:

  1. The Court had already warned the parties regarding discovery that "enough [was] enough."
  2. The Affidavit, which contained substantive opinions and calculations, would prejudice plaintiffs. Discovery was closed, trial was looming, and plaintiffs would not have had enough opportunity to consult their experts or to file supplemental reports addressing the Affidavit.
  3. Defendants had the information in the Affidavit at least by December 2009.  Defendants could have filed the information as part of a timely expert report.
