The Mars patent had gone through reexamination in which the PTO confirmed patentability of the claims without change. The Mars patent had been previously declared valid and infringed. Mars was suing Conlux for almost $40 million and also alleged that the infringement was willful. Thus, the potential total amount of damages Mars was seeking was almost $120 million.

Atherectomy is a field of medical technology which involves the removal of plaque build-up in human arteries.

The jury returned a damage verdict in favor of our client SSI in the amount of $1.1 million, which was in excess of a 10% royalty.

  • Devon v. AMMI, (U.S. Dist. Ct, Cal. 1994). In this case we represented AMMI, the CAFC vacated and remanded a preliminary injunction granted earlier by the district court on the grounds that the district court failed to consider arguments made during the prosecution of the patent. See, 1994 LEXIS U.S. App. 2051. Here, too, the goods involved were medical products (light handle covers used during surgery). Later, in 1994, before the district court, we successfully moved for a summary judgment of non-infringement.

  • C.R. Bard, Inc. v. The Kendall Co., (U.S. Dist. Ct. Cal. – 1993). After a three week trial, a jury returned a verdict finding that a patent owned by our client, C.R. Bard, was infringed by Kendall. Kendall's manufacture and sale of a Foley urine catheter device having a tamper-evident seal shrunk fit on a certain location on the device was found to infringe on Bard's patent rights. After the jury returned its verdict, a separate damage trail was set to begin shortly thereafter. However a multi-million dollar settlement was received and accepted on the damages. The settlement also included a provision for a consent judgment of validity and infringement as well as an injunction.
