China-based Netac Technology Co has been actively enforcing its patent rights in China in recent years, pursuing lawsuits against competitors ranging from local manufacturers to international corporations such as Sony. According to Netac, such cases were either won outright or out-of-court settlements were reached, often resulting in Netac becoming the defendants' product supplier. Furthermore, companies such as Toshiba, Kingston, PNY and Phison, to name a few, agreed to sign licence agreements, entitling Netac Technology to royalties.
