Synventive’s Technology License with HRSflow Has Expired

Synventive Molding Solutions, a global leader in hot runner systems and components for the injection molding industry, and INglass S.p.A. entered into a technology license in 2014 that granted INglass, and its hot runner division HRSflow, access to certain Synventive intellectual property* covering the use of electronic actuators and pin control of sequential valve gated hot runner systems. These technologies, primarily utilized in the automotive interior and exterior industry, improve the injection molding process in numerous ways and eliminate surface defects in the molded part. As a result of the 2014 technology license, HRSflow received the necessary rights to implement Synventive’s patented SYNFLOW® technology. Effective November 6, 2018, the 2014 technology license agreement expired.

Synventive holds the view that certain products manufactured or sold by HRSflow after the expiration date are covered by the subject Synventive patents and other patents issued since the license was granted and therefore constitute a violation of Synventive’s patent rights. In Synventive's opinion, the license expiration means that HRSflow can no longer sell products that utilize the process of modulating the opening of the valve pin in order to solve part quality defects as represented in Synventive’s SYNFLOW® patents.

Synventive regards its ongoing investment in research and development of new technology, and the intellectual property that protects that investment, as fundamental to Synventive’s success. Synventive is committed to enforcing its intellectual property rights to prevent unjustified infringement of those rights, and has filed a lawsuit for patent infringement against INglass S.p.A. and HRSflow GmbH in the Regional Court of Mannheim in Germany based on EP 2 620 266 B1. Synventive is seeking monetary damages, an injunction from selling any hot runner systems infringing upon Synventive’s patented pin control technology, and a recall of infringing HRSflow hot runner systems, controllers and auxiliary equipment.
