Am I infringing the rights of others?

Before you spend time and money on a new trademark, it is important to find out about the rights of others. This preliminary search will provide you with a listing of registered trademarks that may be similar to yours.

Use the preliminary examination if you:

  • wonder whether your trademark is unique or original
  • want to make sure that your trademark has not been registered previously or does not resemble other registered trademarks

Assessment early in the process

If you check whether your trademark is original as early as possible, you will have time to make the necessary changes prior to launch. You can also avoid conflicts with other trademark owners.

Content and quality

  • Norway: we examine whether there are trademark applications or registered trademarks in Norway that phonetically or visually resemble, are identical to, or contain your trademark.
  • The preliminary search does not include unregistered trademarks that are used in Norway. We therefore recommend that you also check other sources, such as the Brønnøysund Register Centre ( for company names and Norid ( for domain names. In addition, you should search online to see whether the word you wish to register is being used by others.

Which databases do we search in?

The searches are performed using professional search methodology. We use databases and tools to which only national patent offices have access. We search in publicly available information. The result of the preliminary search is not binding for the Norwegian Industrial Property Office if you should send in an application at a later date.

Ordering and delivery

You will usually receive the preliminary search report within four working days.
