ITC Asks for Comments on Rohm and Hass Organic Polymer Patent Complaint
The International Trade Commission is asking for comments by about June 1 on public interest factors raised by Rohm and Hass’ May 21 Section 337 patent complaint on opaque polymers (see 13052115). According to Rohm and Hass and its parent company Dow Chemical, Organic Kimya, a company headquartered in Turkey with a Dutch subsidiary, manufactures opaque polymers that infringe its patents. These infringing products are then imported by Turk International and Aalborz Chemical. Rohm and Hass is requesting cease and desist orders and limited exclusion orders blocking import and sale in the U.S. of infringing opaque polymers.

Opaque polymers are hollow-sphere polymeric pigments that allow paint manufacturers to reduce the raw material cost of their formulations by using tiny air voids trapped in the polymer to scatter light. Rohm and Hass’ patented technology involves a process to obtain polymer particles of uniform and ideal size with higher void fractions and “dramatically improved opacifying properties,” its complaint said.
