GlaxoSmithKline Plc (NYSE:GSK): Closing price $52.64

Glaxo’s anti-seizure drug Potiga now carries a black-box warning in the United States regarding risks that include potential vision loss. The warning is the FDA’s most serious, and underscores risks of abnormalities in the eye, vision loss, and skin discoloration, any of which could become permanent, said a Thursday statement. The revised label appears after the risks were signaled by the FDA in April. The agency says that patients should have eye exams prior to starting Potiga and every six months during treatment.

Sequenom Inc. (NASDAQ:SQNM): Closing price $1.92

Ariosa Diagnostics Inc. won summary judgment Wednesday in a patent infringement litigation involving United States Patent No. 6,258,540 against Sequenom Inc., which is 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, providing Ariosa with a complete victory in the case. The patent in question 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 since it attempts to cover this natural phenomenon, which the Court found not patent-eligible subject matter.
