Ohio) — prevailed as lead trial counsel for Ethicon in a 10-day jury trial over ownership of patent applications relating to ultrasonic shears; jury found breach of invention assignment clause, non-compete and agreement not to use confidential information; court then upheld monetary damages and re-assigned patent applications (1:07cv1016, 2009 WL 2707805 (S.D.

One patent that was found to be valid and infringed in the first trial (where Sidley was not counsel) was found by jury to only have one infringing unit and damages of US$1.00. One patent that was found to be infringed had damages reduced to US$5/unit.

GENUS/ABS
- Inguran v. ABS Global and Genus (W.D. WI) — lead trial counsel for defendants in a suit originally asserting seven patents and a claim for trade secret theft. The case followed Sidley’s successful claim on behalf of ABS and Genus against Inguran for monopolization under Section 2 of the Sherman Act in a 2014 litigation in the Western District of Wisconsin. In this case, Sidley obtained summary judgment dismissing plaintiffs’ claims on four patents. One patent was invalidated on indefiniteness grounds, one on written description grounds, and two on non-infringement grounds. Plaintiff dismissed its claims on a fifth patent with prejudice. The court also dismissed plaintiffs’ trade secret allegations as precluded by the previous litigation. Trial was completed on September 10, 2019 on the two remaining patents from the present case and one patent that was remanded for re-trial from the first case, resulting in a design around option being cleared as non-infringing, willfulness being dropped, and plaintiff being awarded a royalty half of plaintiff’s original damages request. The case settled while on appeal.
