Professional practice company; application for admission by patent attorneys

Patent attorneys can join together to form professional associations for the joint practice of their profession.



A prerequisite for admission is that the partners and the members of the management and supervisory bodies belong to the professional groups listed in Sections 52b and 52c PAO. The professional practice company must have chosen an admissible legal form and must not be in a state of financial collapse. It must also provide evidence that it has taken out professional indemnity insurance or present a provisional cover note. The professional liability insurance must be taken out with an insurance company authorized to do business in Germany and must cover the liability risks for financial losses arising from advice and representation in accordance with Section 3 PAO. It must be maintained for the duration of the activity.

After their admission, professional practice companies become members of the Chamber of Patent Attorneys.



Processing time

The Chamber of Patent Attorneys will decide on your application once all the necessary application documents have been submitted.

Required documents

  • Application for admission of a professional practice company

    A patent attorney company is obliged to take out professional liability insurance with an insurance company authorized to do business in Germany and to maintain it for the duration of the license. The minimum insurance amount is 2,500,000 euros for a single claim. The insurer's benefits for all damages caused within one insurance year may be limited to the amount of the minimum insurance sum multiplied by the number of partners and managing directors who are not partners. However, the maximum annual benefit must amount to at least four times the minimum sum insured (Section 52j PAO in conjunction with Section 45 PAO).
