GSK GSK plc

LONDON--Vectura Group PLC (VEC.LN) said on Wednesday it has filed a patent infringement lawsuit against GlaxoSmithKline PLC (GSK.LN) because GSK didn't exercise the option to license any additional patents under an agreement with Vectura dated August 2010.

Vectura, which specialises in products for inhaled airways disease, also reiterated its 2016 revenue guidance.

The lawsuit claims infringement of one of Vectura's patents in the U.S., the company said. The separate agreement with GSK relating to the legacy Skyepharma dry powder formulation technology used in GSK's Ellipta product range is unaffected by this lawsuit, Vectura said.

In August of 2010, GSK and Vectura entered a license and option-to-licence agreement relating to a number of Vectura patent families and various formulation technologies relevant to the Ellipta products.

Vectura shares at 1630 GMT up 0.20 pence, or 0.1%, at 150 pence, while GSK shares up 29.50 pence, or 1.8%, at 1,696.50 pence.
