Examination for patentability


To obtain a patent for your invention, you must first file an application for the grant of a patent ("patent application") with the German Patent and Trademark Office (DPMA).

In order to maintain your patent application or patent protection, you must pay annuities for each patent or application. These are due from the beginning of the 3rd year after filing and in each subsequent year. You must pay the renewal fees without being asked to do so.

With the receipt of the application the filing date is secured. An automatic examination for novelty and inventive step does not take place. For this purpose, a request is required, which can be filed by the applicant, but also by any third party, up to the expiry of 7 years from the filing date. Otherwise, the application is deemed to be withdrawn.

You may have a search carried out on an invention already filed before the examination. Such an early search is useful if, for example, you want to get a preliminary impression of the patentability and thus of a later examination result.

Filing the request for examination

To actually obtain a patent, you must file a request for examination and pay the examination fee of 350.00 EUR. Only then can the DPMA examine the application and, if necessary, grant a patent.

Note: If you wish, you can also file a search request for your application before you file your request for examination, for which a fee will be charged. In this case, the protectability of your filed invention will be assessed and substantiated in a detailed search report, which also contains the documents that may be relevant for the further examination of the patentability of your invention.

During the examination procedure, the patent examiners of the DPMA ensure that your invention meets the following criteria:

  • Novelty
  • inventive step
  • industrial applicability

In addition, it must be a technical invention that is disclosed in an executable manner.


Your patent application remains secret for 18 months, after which it is disclosed, i.e. published. In the database "DPMAregister" a reference to the publication of the so-called Offenlegungsschrift appears. You can view it there from the first day of publication.

The period of secrecy is intended to give you the opportunity to follow up your application or, if necessary, to withdraw it before the publication of the Offenlegungsschrift. The disclosure notice will appear irrespective of whether you have filed a request for examination or not.

Notice of Examination

If you have filed a request for examination of your application, a patent examiner will determine the prior art relevant to your invention and examine whether a patent can be granted against this background.

If it is determined that your invention is new, involves an inventive step, is disclosed in an executable form and is susceptible of industrial application, and that your application also meets all other formal requirements, the DPMA will grant you a patent.

If your invention does not meet the requirements or your application has other deficiencies, you will be notified in an examination communication.

You then have the opportunity to comment and correct the deficiencies within a period specified in the examination communication. Please note that all amendments must be within the scope of the original disclosure, i.e. the description of your invention filed on the filing date.

Grant and Publication

After successful examination of the patent application, a patent can be granted. The publication of the grant is made in the relevant part of the Patent Gazette. It can also be searched in the databases "DEPATISnet" and "DPMAregister". With the publication of the grant of the patent in the Patent Gazette, the property right of the patent proprietor comes into existence. A granted patent is effective for a maximum of 20 years from the day after the application is filed.

A patent is granted for a technical invention that is new, involves an inventive step, and is susceptible of industrial application.


  • An invention is considered new if it does not belong to the prior art. Prior art is considered to be all knowledge that has been made available to the public in writing or orally anywhere in the world prior to the filing date.
  • For this purpose, the examiners of the DPMA search and compare patent specifications, published patent applications, technical literature and lectures from many countries.
  • Furthermore, prior art includes prior publications by the inventor or the applicant himself, for example, conference papers, articles in scientific journals and exhibitions at trade fairs.

Inventive step:

  • It is not sufficient that an invention is new. It must also be based on an inventive step, i.e. it must not be obvious from the prior art.
  • This criterion ensures that not every innovation, no matter how minor, already leads to an IP right.
  • Property rights for inventions that hardly differ from the known would hinder the use and development in the field. This would block progress.

Industrial applicability:

  • Industrial applicability is basically satisfied by all inventions that are producible or usable in any industrial field.
  • Ideas that are not feasible may not be patented.
  • In addition, for socio-ethical reasons, medical procedures are not considered to be industrially applicable. The physician should be free to choose the procedure for the surgical or therapeutic treatment of his or her patients and not be hindered by patent rights. However, this exception applies only to the medical procedures, not to the products used in the process.
  • Objects such as medical devices, surgical tools, dressings, pregnancy tests or pharmaceuticals can be patented.

You must submit the following documents with the patent application:

  • Description of the invention
    • The description must be disclosed clearly and completely enough to enable a person skilled in the art to carry out the invention.
    • The description forms the basis for the patent claims.
  • Naming of the inventor
  • Claims
    • The patent claims determine the scope of protection of the patent, i.e. they specify what exactly is to be protected.
  • Drawings, if applicable
  • Summary

The current costs can be found in the cost information sheet on fees and expenses of the German Patent and Trademark Office and the Federal Patent Court.

  • Filing of the request for examination: 7 years from the filing date. Renewal fees must be paid from the 3rd patent year.
  • Payment of the examination request fee: within 3 months after receipt of the examination request.
  • Opposition to the grant of the patent: within 9 months from the date of publication of the grant of the patent in the Patent Gazette.
  • Payment of the renewal fee: without request at the beginning of the third and each subsequent year, calculated from the filing date. If you fail to pay the renewal fee on time or in full, the patent will lapse.

The typical processing time , if you submit the exam application within the first 4 months of filing, pay the exam fee, and have not filed any extension requests, is 3.2 years on average .
