I have idea for product (wich i belive ,is not developed yet ),does somebody knows how i can check that? thanks
Be careful when you search for a patent or trademark which you want to develop. Perhaps somebody in some part of the world would have forseen it. It would be a good idea to get a professional advice from attorneys who specialize in IP rights. For the start you can do a preliminary search in 1. US Patents Office (USPTO) 2. EU trademark search for EU countries.
