Representative Matters

LifeScan Scotland, Ltd. (a J&J subsidiary) v. Shasta Technologies
Served as lead counsel for the defendants in patent infringement case in the U.S. District Court for the Northern District of California and its related appeal. The Federal Circuit, in a lengthy published opinion, reversed the lower court’s entry of a preliminary injunction and rejected Lifescan’s claim that the defendants' sales of the GenStrip infringed Lifescan’s ’105 Patent. The Federal Circuit held that Lifescan’s right to enforce the 105 Patent was exhausted as a matter of law.

Pharmatech Solutions, Inc. v. LifeScan Scotland Ltd.
Served as lead counsel before PTAB in a successful IPR  challenge of Lifescan’s ’105 Patent and its related appeal.

Dananberg v. Payless ShoeSource
Successfully defended the national retailer and manufacturer in a patent case in the U.S. District Court for the District of New Hampshire where the plaintiff sought hundreds of millions of dollars in damages. Litigation resulted in multiple favorable Markman rulings, and ultimately, summary judgment on all claims.

Alzheimer’s Institute of America, Inc. v. Mayo Clinic, et al.
Represented the leading nonprofit organization in a licensing and patent dispute involving the “Swedish Mutation,” a genetic mutation related to early-onset Alzheimer’s Disease. The defendant used cell lines containing the mutation, which was patented by the client, for research purposes. Argued successfully in arbitration proceedings that these cell lines were not included in the scope of the licensing agreement and this led to a very favorable settlement.

In the Matter of Certain Foam Footwear
Served as lead counsel for Collective Licensing International in an International Trade Commission action claiming patent infringement stemming from the sale of popular clog-style footwear. Achieved a complete victory in the case. The judge exonerated all accused shoes and invalidated one of Crocs’ two principal patents.

Bath & Body Works, Inc. v. Luzier Personalized Cosmetics
Served as lead defense counsel in a two-week jury trial before the U.S. District Court for the Southern District of Ohio. Obtained a favorable verdict on behalf of the defendant, which was affirmed on appeal before the Sixth Circuit.
