Acne Gel Patent infrigement
June 2, 2009
Stiefel Laboratories Inc., a Florida-based dermatology company, sued KV Pharmaceutical Co. last week, alleging an infringement of a patent for Duac topical gel, an acne medication.
The lawsuit, filed Thursday, seeks to stop KV from manufacturing and selling a similar topical gel. KV had submitted a new drug application for the gel to the U.S. Food and Drug Administration, according to the lawsuit.
A Stiefel spokeswoman declined to comment on the lawsuit.
A request for comment from KV was not immediately returned.
Brentwood, Mo.-based KV has suspended drug shipments, halted all production and recalled painkillers because the tablets were oversized.
In March, KV said it entered into a consent decree with the FDA that outlines a series of measures that will permit KV and its subsidiaries to resume manufacturing and distribution.
