Trademark Searches
Trademarks can be registered locally or around the world. Some search tools:
-International Marks under the Madrid Protocol - Madrid Protocol search
-European Union Trademark Search
Beware, searches on available domain names are sometimes captured by web sites and they can register the domain before you … and then charge a high fee to release it. Network Solutions was sued over this for doing this large-scale and the fees were not that high but this has happen elsewhere on a small scale and can cost thousands.
