nachfolgend als „Patentanwälte“,

hereinafter referred to as “patent attorneys”, “we”, “us”. These data protection regulations apply to the use of the website and data processing by the patent attorneys.

The in-house data protection officer of the patent attorneys is Ms. Alina Hammel, who can be contacted at .


Personal data are all information about personal and factual circumstances of a certain or determinable natural person. This includes, for example, information such as your name, your address and your telephone number or e-mail address. No personal data is any information that does not identify you, for example your age, gender or professional training. In the following, however, only your IP address is relevant with regard to the term “personal” data. We do not collect any other data that could possibly be used to draw conclusions about your person – except in application procedures or direct contact.

3. collection and storage of personal data as well as type and purpose of their use

When you call up our website, information is automatically sent to the server of our website by the browser used on your end device. This information is temporarily stored in a so-called web server log file and can be made available to the host for order data processing (e.g. for creating click statistics within the website, specifically: “how often was post XY clicked on?)

The following information is collected without your intervention and stored until automatic deletion, which usually occurs at the end of the session (so-called “session cookies”):

  • IP address of the requesting computer
  • Date and time of access
  • Name and URL of the retrieved file
  • Website from which the access takes place (referrer URL)


  • the browser used and, if applicable, the operating system of your computer and the name of your access provider.

It should be explicitly mentioned that this data does not allow any direct conclusions to be drawn about your person; only in combination with other data not collected by us is it possible to identify you beyond doubt. We process the data mentioned above for the following purposes:

  • To ensure a smooth connection of the website (e.g. the website cannot be delivered to you without the system-immanent retrieval of the IP address)
  • Guarantee of a comfortable use of our website (e.g. Google Maps, see below for a more detailed privacy policy on the Google Maps Plugin)
  • Evaluation of the system security and stability (e.g. the above-mentioned data enables us to trace error messages that were displayed to you during the use of our website and, if necessary, to correct them directly)

The legal basis for data processing is Art. 6 para. 1 sentence 1 lit. f DSGVO. Our legitimate interest follows from the above listed purposes for data collection, the examples given serve to illustrate the purposes mentioned. Under no circumstances do we use the collected data for the purpose of drawing conclusions about your person.

Furthermore, we use cookies and analysis services when you visit our website. You will find more detailed explanations in sections 4 and 5 of this privacy policy.

4. Passing on of Data

Your personal data (see above “session cookies” and IP address) will not be transferred to third parties for any other purposes than those listed below.

We only pass on your personal data to third parties if:

  • you have given your express consent in accordance with Art. 6 Para. 1 S. 1 lit. f DSGVO, whereby by using our website you agree that in particular session cookies may be installed on your computer and the IP address may be transmitted to our hoster (1&1 AG)
  • the disclosure pursuant to Art. 6 Para. 1 S.1 lit. f DSGVO is necessary for the assertion, exercise or defence of legal claims and there is no reason to assume that you have an overriding interest worthy of protection in not disclosing your data,
  • in the event that there is a legal obligation to pass on the data pursuant to Art. 6 para. 1 sentence 1 lit. c DSGVO. By order of the competent authorities, we may in individual cases provide information about this data (e.g. IP address), if this is necessary for the purposes of criminal prosecution, danger prevention, the fulfilment of the legal tasks of the constitution protection authorities or the military counterintelligence service or for the enforcement of intellectual property rights.


We use cookies on our website. These are small files that are automatically created by your browser and stored on your end device (laptop, tablet, smartphone or similar) when you visit our site. The German Wikipedia defines cookies as follows:

„Ein Cookie ([ˈkʊki]; englisch „Keks“) ist eine Textinformation, die die besuchte Website (hier „Server“) über den Webbrowser auf dem Computer des Betrachters („Client“) platziert. Der Cookie wird entweder vom Webserver an den Browser gesendet oder von einem Skript (etwa JavaScript) in der Website erzeugt. Der Client sendet die Cookie-Information bei späteren, neuen Besuchen dieser Seite mit jeder Anforderung wieder an den Server.“

Cookies do not cause any damage to your end device, do not contain viruses, trojans or other malware.
Information is stored in the cookie that is related to the specific terminal device used and can be regarded more as a “footprint” than an identification mark. As a result, we do not obtain direct knowledge of your identity.

The use of cookies serves on the one hand to make the use of our offer more pleasant for you (e.g. the Google Maps Plugin, see below) and to enable us to continuously optimize the website and the offer contained therein (web server log files).

So-called “session cookies” enable us to recognize that you have already visited individual pages of our website. After leaving our site, these are automatically deleted from your computer.

In addition, as mentioned above, we use temporary cookies to optimize user-friendliness and page content. These cookies are stored on your end device for a specific and defined period of time. For this purpose, the use of our website – for our technical means – is statistically recorded in an anonymous form. The evaluation, which mainly consists of “click numbers”, “click times” or similar, provides us with feedback on the extent of use of our website. These temporary cookies enable us to recognize that you have already been on our site (e.g. for the calculation of the number of visitors; for the calculation of this value, the same person who has visited our site two or more times a day is counted as only one visitor). These temporary cookies are automatically deleted from your computer after a previously defined period of time.

The data processed by cookies are required for the above-mentioned purposes in order to safeguard our legitimate interests and those of third parties in accordance with Art. 6 Paragraph 1 S. 1 lit. f DSGVO.

Most browsers automatically accept cookies, but you can configure your browser so that no cookies are stored on your computer or a message always appears before a new cookie is created. However, completely deactivating cookies may mean that you will at least not be able to use all the functions of our website, or that you may not be able to connect to our website at all.

6. PRIVACY STATEMENT ON 1&1 WebAnalytics

On the basis of Art. 6 Para. 1 S. 1 lit. f DSGVO, we use a data protection compliant web analysis service from 1&1 Internet AG, 1&1 WebAnalytics, to ensure that our website is designed to meet the needs of our customers and is continuously optimized. On the other hand, we use the tracking measure to evaluate the use of our website statistically and anonymously for our technical means for the purpose of optimizing our offer for you.

As briefly mentioned above, 1&1 WebAnalytics uses temporary cookies which are created on your computer by our website and are automatically deleted after a previously defined period of time.

The legal reasons for the disclosure of your personal data mentioned under point 4, item 3 also apply accordingly to 1&1 Internet AG. 1&1 is also entitled to pass on your data to third parties if these third parties are commissioned by 1&1 AG to evaluate this data purely for the purpose of our website.

You can deactivate the creation of cookies on your computer with the browser settings mentioned in the last paragraph of point 5, should you not wish your personal data to be evaluated either by us or by 1&1 Internet AG.
