Item 8.01. | Other Events |
On March 14, 2014, Idenix Pharmaceuticals, Inc. (Idenix) issued a press release announcing that it has filed patent infringement lawsuits against Gilead Sciences, Inc. and/or certain of its subsidiaries (Gilead) in each of three countries - France, Germany and the United Kingdom.
The lawsuits allege that Gilead infringes Idenixs recently-granted, co-owned European patent EP 1 523 489 that covers 2-methyl-2-fluoro nucleosides for treating the hepatitis C virus (HCV). In these lawsuits, Idenix is seeking remedies with respect to Gileads marketing and sales of drugs containing sofosbuvir, which Idenix believes infringes its European patent.
Other Ongoing Patent Disputes
Idenix has several ongoing litigation and administrative matters involving Gilead. In December 2013, Idenix announced it filed two lawsuits against Gilead: a patent infringement lawsuit in the United States District Court in Boston, Massachusetts (Idenix U.S. Patents 6,914,054 and 7,608,597) and a separate patent infringement and interference lawsuit in the United States District Court in Wilmington, Delaware (Idenix U.S. Patent 7,608,600 and Gilead U.S. Patent 8,415,322).
In February 2012, the U.S. Patent and Trademark Office (USPTO), initiated a patent interference between one of Idenixs co-owned patent applications and a patent owned by Gilead. In January 2014, the USPTO determined that Idenix is not entitled to priority of invention and judgment was entered in favor of Gilead. Idenix challenged this decision in the U.S. District Court for the District of Delaware.
In December 2013, the USPTO declared a second patent interference between Idenixs U.S. Patent 7,608,600 and Gileads U.S. Patent Application 11/854,218, both related to the use of certain 2-methyl, 2-fluoro nucleoside compounds to treat HCV infections.
In August 2013, Idenix filed a request with the Chinese Patent Offices Patent Re-examination Board, or the PRB, to invalidate Gileads Chinese Patent No. ZL.200480019148.4.
Gilead Sciences has also filed suit against Idenix in various jurisdictions outside the United States (Canada, Norway and Australia) to invalidate granted Idenix patents covering certain 2-methyl-2-fluoro nucleoside compounds and their use in treating HCV or other Flaviviridae viruses.
The full text of the press release is attached hereto as Exhibit 99.1. Exhibit 99.1 is incorporated by reference into this Current Report on Form 8-K.
