The search

You can search the trade mark database with or without search operators. Without search operators, the search engine will exclusively find identical terms.


How the search works

After you have entered your search term or terms into the search field and started the search, the following fields will be searched for matches:


  1. Trade mark titles
  2. Word elements of word/figurative marks
  3. Trade mark numbers
  4. Application numbers
  5. Owner
  6. Representative
  7. Goods and services


You will obtain results if the character string found matches what you typed exactly. For example, if you search for ‘photo’, it will only find results with the word ‘photo’ and not ‘photos’, ‘photograph’ or ‘photographer’. To search for alternative spellings or similar terms, please use the advanced search options.

If you use several search terms, the search results will contain at least one of these terms (the standard operator OR).


Upper/lower case

The search does not differentiate between upper and lower case letters.


Search terms with umlauts and diacritical marks

Umlauts (ä, ö, ü) and diacritical marks (e.g. à, ô, ç) are not taken into account by the search. This is also the case if using quotation marks to search for exact phrases. It therefore does not matter if you type umlauts or accent marks – a search for ‘schön’ or ‘schon’ will find the same results. You cannot, however, use ‘ae’ ‘oe’ or ‘ue’ in place of ‘ä’, ‘ö’ or ‘ü’.


Search terms with special characters

The search engine does not recognise special characters. This includes the characters +  -   /  & !  (  ). Full stops and commas are recognised.

Because special characters function like spaces, the character strings before and after a special character (PC-Doctor) are handled as though they are separate terms (search for ‘PC’ and ‘Doctor’). Therefore, please place search terms with special characters in quotation marks – “PC-Doctor”.
