At the PNZ, we provide you with access to selected licensed databases which enable you to perform independent searches on site. Our experienced and competent specialists are on hand to offer any assistance you may need.

We discuss search strategies with you and provide you with an introduction into the search options available to you through the various databases. This enables you to have direct influence on your research into the current state of the art.


Databases in the PNZ

Commercial databases offer convenient search options and special features in contrast to the freely available search offers.

No knowledge of search languages is necessary, large numbers of hits can be quickly viewed and a convenient selection can be made for further processing.

In addition to analysis options of the hit lists (applicant, technology area, time, etc.), the commercial databases offer, among other things, working with the search history, setting up search profiles and automatic search queries.

At the PNZ we have the following databases, among others, ready for you:


Patents, Utility Models

Logo Patselect

Orbit: Comprehensive databases for patent research; offers more comfortable usage options than DepatisNet with regards to a comparable data basis.


Trade Marks / Design

Cedelex Logo

Cedelex: Trademark and design database with German, European, and international trademarks and design. Contains good inquiry possibilities for similarity inquiries.
