Static Control’s ZeroTwist Gear Technology Eliminates Risk of Infringing Canon OPC Gear Patents

by Imaging Solution Bureau

After years of research, development and investment, Static Control is releasing imaging systems featuring its patented ZeroTwist gear technology for OPC drums that eliminate the risk of infringing OPC drum gear patents held by Canon.

This year Canon sued 34 companies for patent infringement, putting enormous pressure on remanufacturers, distributors and resellers both large and small to avoid court action and crushing penalties. All of the companies named in complaints filed in both federal U.S. District Court and the International Trade Commission have settled the complaints, most with conditions favorable to Canon.

Industry analysts estimate that up to 70 percent of all remanufactured laser printer cartridges sold today use OPC drums with gears that feature a twist design that risks infringing Canon’s patents. Static Control’s gears do not slant or twist, and they have 90-degree angles. Static Control was granted U.S. patent 7,813,676 B2 in October, 2010, and U.S. patent 8,073,364 B2 in December, 2011, for OPC drum drive gears whose design eliminates the risk of infringing Canon’s patent.

“After an investment of thousands of legal and engineering hours and many millions of dollars in plastic injection molding equipment, additional personnel and time devoted to system testing, we now have fully functional gear solutions that eliminate the risk of infringing Canon’s patents,” said Ed Swartz, Founder and CEO of Static Control.
