Search rooms of the German Patent and Trade Mark Office in Munich and Berlin

Using search options

The two search rooms of the DPMA in Munich and at the Technical Information Centre (TIZ) in Berlin also form part of our extended customer care and services. There, you can use various information options relating to industrial property rights. For example, you can perform prior art and novelty searches and monitor filing activities in specific fields of technology or of specific applicants. Furthermore, you can conduct searches on your own for individual patents, utility models, trade marks, and designs and identify the legal status of specific applications.

The search rooms have the character of reference libraries. All kinds of documents may be used there, but no documents may be taken out of the search rooms.

Assistance to users

Irrespective of whether you wish to search for specific IP rights or the state of the art, the staff of the search rooms will help you choosing the appropriate search tools and explain how to use these tools.

Collections of patents, trade marks, utility models and designs

Collections relating to patents, trade marks, utility models and designs

In the search rooms you have access to the following information sources:

  • national and foreign patent documents (access via DEPATIS and on paper collections)
  • national and foreign patent, trade mark and design gazettes/journals
  • EPIDOS-INPADOC indexes on patent documents from all over the world since 1968
  • legal (procedural) status information on German IP rights via DPMAregister
  • trade mark databases and dictionaries
  • design index, arranged by classes of goods (the index comprises the German register (index) cards from 1988 to 2003)
  • search tools (for example International Patent Classification)
  • collections of standards, such as DIN, ISO, ASTM
  • books and journals (focusing on technology, sciences and industrial property protection)

Many of the collections are available on CD and can be viewed in the search room.

DEPATIS patent information system

The electronic DEPATIS patent information system has almost completely replaced the paper search file of the patent examiners at the DPMA and the corresponding collections for the public. In the public search rooms, DEPATIS work stations are available to the public.

File inspection

You can inspect case files in the search rooms of the DPMA in Munich and Berlin or at the enquiry unit in Jena, but you first need a communication sent by the DPMA stating that the case files are available for file inspection. To receive such a communication you must send a letter requesting the inspection of a case file to the DPMA (see Sec. 31 Patent Act, Sec. 8(5) Utility Model Act, Sec. 62 Trade Mark Act, Sec. 22 Design Act). About two weeks after making the request you will usually receive the respective communication. For details about file inspection, particularly about online file inspection, please click here.
