  • Learn about identical or similar word trademarks through many different lookup features such as “true-flase”, similar, original, phonetic and “near similar” lookup;
  • Search for identical or similar trademarks by using the image lookup function.

Look up for the trademark before submitting the application if it finds an intermediate or similar trademark.
