Chongqing Jianqiao Sues HolleyPharm Again For Patent Infringement

This article was originally published in PharmAsia News

Executive Summary

Chongqing Jianqiao Pharmaceutical Development has again sued Holley Pharmaceuticals, alleging that the latter's Duo-Cotecxin (dihyhroartermisinin piperaquine) tablets infringe on its patented compound for piperaquine tablets. Chongqing Jianqiao demands that HolleyPharm stop production and sale of the product, pay RMB 1 for economic losses, as well as issue a public apology and pay for court expenses. HolleyPharm claims thatDuo-Cotecxin's components are totally different from those of Chongqing Jianqiao's piperaquine tablets and it will be fighting the suit. Meanwhile, HolleyPharm has appealed its previous patent infringement case (PharmAsia News, Jul. 28, 2008). Analysts observe that an unfavourable ruling will negatively impact the firm as it will have to stop producing and selling Duo-Cotecxin locally if it loses the two cases.
