The Term for filing a German patent application

The term of filing a patent application in Germany claiming priority is 12 months from the priority date.

Minimum Patent Filing requirements in Germany

The official language of the German patent application is German. The certified German translation of an application filed in English or French may be provided within 12 months from filing the patent application or within 15 months from the earliest priority date if any. If the application is filed in any other foreign language, the certified German translation should be provided within three months from filing.

The following documents are required for successful filing of a new patent application: a request for the grant of a patent, and specification, i.e. description of the invention, claims, drawings, if any, and abstract.

To confirm the priority right, the applicant must submit a сopy of the Priority Document within 16 months from the earliest priority date. Certification or legalization is not required. If the priority document is not filed in English, French, Italian or Spanish, a German translation shall be filed subsequently within a month from submitting thereof. German translation of priority documents filed in English, French, Italian, or Spanish shall be subsequently furnished only upon invitation by the German Patent and TradeMark Office. The translation should be certified by a lawyer or a patent attorney or be done by an officially authorized translator.

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 15 months from the filing date; however, the naming of the inventor should preferably be filed together with the patent application.

Analysis of a patent application in Germany

Patent applications in Germany undergo formal and substantive examinations. The request to conduct a substantive examination must be filed within seven years from filing the German patent application.

Novelty grace period for patent application

German patent application may be filed within six months after the disclosure at an official or officially recognized international exhibition or when such a disclosure was made in bad faith by any third party. The exhibition must fall within the terms of the Convention on international exhibitions signed in Paris on November 22, 1928.

Annual fees are due each year starting from the 3rd one and should be paid before the expiry of the last day of the month in which the anniversary of the filing date occurs. If the fee is not paid before the expiry of the second month from the due date, it may be paid together with a surcharge of EUR 50 before the expiry of the sixth month from the due date.

The maximum protection period of a utility model in Germany is ten years from the date of filing.

For a person neither residing in Germany nor having a principal place of business nor an establishment in Germany, it is required to perform patent prosecution through a registered German patent attorney or a foreign lawyer who is a national of a Member State of the European Union or a State party to the Agreement on the European Economic Area authorized to represent an applicant in proceedings before the German Patent and Trade Mark Office.
