Taro files patent infringement suit against three companies

HAWTHORNE, N.Y. An Israeli generic drug maker has sued three other companies, alleging patent infringement.

Taro Pharmaceutical Industries announced Monday that it had filed suit in the U.S. District Court for the District of New Jersey against Synerx Pharma, DPT Labs and Karalex Pharma, alleging infringement of U.S. Patent No. 7,560,445. The patent covers Taro’s Ovide (malathion) lotion in the 0.5% strength, a treatment for head lice.

Taro said the defendants’ generic versions of the drug infringed its patent, and it’s seeking injunctive relief and damages.
