Hello Guys,
Here is a case, somebody has registered domain name using my trademark, something like trademarkwidget.net , they are developing it and are promoting it. I contacted them and told to transfer the domain to me, but they replied that they are not going to do it if I like I can buy it for several hundred dollars. What can I do? It seems that they are not located in USA or Europe, they are located somewhere in pakistan or bangladesh... Should I begin court case? somewhere like WIPO? but it will be more expansive...
What can I do?
