Bone Care, Int'l v. Pen Tech Pharm., No. 08 C 1083, Slip Op. (N.D. Ill. Mar. 30, 2011) (Dow, J.).
Judge Dow denied defendants' (collectively "Pentech") motion for summary judgment of invalidity for lack of enablement and written description. The Court also denied plaintiff Bone Care International's cross-motion for summary judgment that the patent-in-suit was enabled by its specification, in this patent case involving methods of treating hyperparathyroidism that is secondary to end-stage renal disease. The parties finished briefing their cross-motions weeks before a bench trial began, including the issues in the motion. And by the time of the opinion, the parties had filed extensive post-trial briefing -- the Court allowed briefs up to 280 pages in length. As such and in light of its coming opinion ruling on all factual issues, the Court did not provide a detailed analysis of its reasoning. Instead, it focused on one of the most common hurdles to summary judgment, the battle of the experts. The parties' experts set forth competing views of the facts and circumstances on the case. Because both parties relied upon those experts to make their cases, summary judgment was not proper.
The Court, however, did commit to resolve the issues as part of its written trial decision.
