TrademarkBob is a very easy to use tool to indentify potential trademark risks. I'm a professional name developer and I use TrademarkBob to assess a large list of names and identify which names are clear of conflicts. Review collected by and hosted on G2.com.
While it is impossible to get a definitive answer on trademark availibility (unless there is an obvious direct conflict, in which case the answer is no), TrademarkBob lays out th potential conflicts and then you have to interpret the results. We would all love a black and white, yes or no answer. But there are a lot of gray areas in trademark law, and sometimes the answer is "maybe." Review collected by and hosted on G2.com.
