ZTE has accused rival Huawei of patent trolling, suggesting that the latter is using litigation as part of tactical competition in the European marketplace. In a statement issued yesterday, ZTE said that Huawei’s legal suit regarding the use of trademarks in Europe was spurious. The manufacturer claims that it ceased using the trademark in question a year before Huawei was awarded any rights to it, and therefore “the injunction has no impact on ZTE’s business.”
