Sequenom Inc. (SQNM) Stock Crushed After Patent Ruling

October 31, 2013 11:38 AM EDT Send to a Friend
Ariosa Diagnostics, Inc., won summary judgment yesterday in a patent infringement litigation involving U.S. Patent No. 6,258,540 against Sequenom, Inc. (Nasdaq: SQNM) an exclusive licensee of the patent from Isis Innovations, Inc.

The United States District Court for the Northern District of California invalidated the '540 patent at issue, giving Ariosa a complete victory in the case. The patent at issue is related to the detection of fetal cell-free DNA in the bloodstream of pregnant women, and Sequenom claimed that it applied to tests for the determination of certain fetal genetic characteristics.

The Court invalidated Sequenom's patent because it attempts to cover this natural phenomenon, which the Court found is not patent-eligible subject matter.

In light of repeated public threats by Sequenom regarding enforcement of its '540 patent, Ariosa filed suit against Sequenom in December 2011, seeking a declaratory judgment that its Harmony™ Prenatal Test did not infringe Sequenom's patent. Sequenom counterclaimed for patent infringement and moved for a preliminary injunction.
