2065438+In June 2006, ZTE, Huawei and WeChat were sued by American companies. What happened was this: Uniloc sued Tencent America in the U.S. District Court for the Eastern District of Texas, on the grounds that the voice group chat and video group chat functions of WeChat infringed their patents and demanded that WeChat immediately suspend these functions! Tencent responded: The indictment has not been received.
Uniloc, known as the "patent hooligan" in the industry, is engaged in patent licensing affairs. The company itself does not manufacture patented products, and by purchasing patent licenses, it issues patent lawsuits to other large companies to obtain high profits.
The concept of applying for a patent in the United States is very vague, which makes such companies take advantage of it. For example, if someone develops a software, Uniloc will not sue the developer. Uniloc claimed to have a patent to use this software and sued other rich people who used this software.
It is reported that Uniloc sued large enterprises in the federal district court in eastern Texas because the judges of this court specifically filed a lawsuit for Uniloc.
Uniloc takes advantage of legal loopholes, so large companies should do their homework when developing and publishing software.
