Detailed information related to the European Patent.

  • Translation 

Switzerland & Liechtenstein are London Agreement countries and share an official language with the EPO. Therefore, a separate Validation request is not mandatory.

  • Representation by a patent attorney

It is not obligatory to assign a registered attorney in Liechtenstein. However, foreign applicants are required to appoint a local Liechtenstein attorney as an "Address for Service" for receiving, interpreting, and handling any communication from the Swiss Intellectual Property Office on behalf of the applicant as Liechtenstein has no its own patent office.
