What Is the Filing and Case Overview?
Belcher Pharmaceuticals, LLC filed a lawsuit against International Medication Systems, Limited (IMS) in the U.S. District Court for the District of Delaware (Case No. 1:18-cv-00960-LPS-CJB) on April 3, 2018. The case centers on patent infringement and misappropriation of trade secrets related to a proprietary pharmaceutical delivery system.
Claims include patent infringement on U.S. Patent No. 9,571,480 and trade secret misappropriation under the Defend Trade Secrets Act (18 U.S.C. §§ 1836 et seq.) and Delaware Uniform Trade Secrets Act (UDSTA). The plaintiff alleges that IMS used confidential information and patents owned by Belcher to develop similar drug delivery technologies without authorization.
The defendant, IMS, denies wrongdoing, claims patent invalidity, and contends that the patents and trade secrets are unenforceable or were improperly obtained.
