Assisted Research Services on site



Please arrange an appointment for the reasearch via phone +49 241 80-94480 with us.


The PNZ provides a research workstation for two time units daily for your own research in the expert databases for patents, trademarks and design.
Searches are possible from 9 to 12 and from 13 to 16 o'clock. Both units can also be booked one after the other, but it is necessary to take a break for airing.
Appointments can be made by telephone: +49 241 80-94480.

The offers are directed only to RWTH Aachen University employees and students.

Alternatively, your searches for industrial property rights or standards can be managed by us online. Or you can order your search from us using our order forms.


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.
