Handset makers in China have formed an alliance to prepare for possible patent battles with Apple, Microsoft and Nokia. Coolpad, Konka, TCL, ZTE and Lenovo were among the companies named in a report by DigiTimes on Friday. The number of lawsuits filed in China is expected to increase as Microsoft, Nokia and Apple try to increase market share there, the report says. Nokia has already filed patent infringement suits against several Chinese phone makers and Microsoft has gone after Huawei to try to secure a patent licensing deal. Huawei responded to Microsoft’s threats in early November and explained that it has 65,000 patents worldwide. “We have enough to protect our interests,” Huawei Devices chief marketing officer Victor Xu said. “We are a very important stakeholder in Android.” Each of the Chinese companies reportedly has a large patent portfolio and, combined, they could create enough of a force to stave off at least some of the patent-related lawsuits that have plagued other companies.
