The POA should be submitted only in case the representative is not a German Patent Attorney. The legalization or notarization of the POA is not required.

The applicant must designate the inventor(s) and confirm that to his knowledge no other person has contributed to the invention. If the applicant of a German patent application is other than the inventor, or, not the sole inventor, the applicant must state how the right to the invention has been acquired. This document must be submitted within 30 months from the priority date. If an applicant does not provide the document within the stipulated period, the Office will invite the applicant to comply with the requirement within a time limit fixed in the invitation.
