PatZilla is a modular patent information research platform and toolkit with a modern user interface and access to multiple data sources.

Project description

IP Navigator


The IP Navigator is a modular patent information research platform and toolkit with a modern user interface and access to multiple data sources.

Its goal is to provide the community with convenient access to the OPS service from EPO and other professional patent search APIs. It is also used as a building block for integrated vendor solutions.


The software got some applause from professional researchers for its unique user interface and rich feature set when it was released to the first audience in 2014. We hear from our users they are still having a great pleasure working with it on a daily basis.

After four years of development, the source code finally gets released under an open source license in 2017. We are looking forward to opening up the development process as well, every kind of participation and support is very much welcome.


  • Multiple data source APIs.
    • Use different patent search services with varying coverage.
    • Connect to multiple services for pdf-, image-, bibliographic data and fulltext acquisition.
  • User interface. Based on contemporary web technologies and responsive design, it works on multiple devices. Use it on PCs, tablets, smartphone devices or as a multi-screen solution. The clear and well-arranged design and layout permits efficient screening of large numbers of patent documents.
  • Dossier management. Manage different collections of patent documents and apply ratings and comments.
  • REST API. Through the extensive REST API, all functionality is available to 3rd-party systems. Deep integration has no limits.
  • Sharing. Well-designed collaboration features allow efficient sharing of information with your colleagues, even across the boundaries of in-house systems.
  • Multitenancy. The software can operate on behalf of different vendors. It’s easy to apply custom branding.

Getting started

Getting started with the software or deploying it yourself is quite easy if you are familiar with Python. We will only cover development here, see install docs about how to run a sandbox instance. The software should work on any other Linux or BSD distribution, but this is beyond the scope of the README.

Project information

The source code lives on GitHub and the Python package is published to PyPI. You might also want to have a look at the documentation.

The software has been tested on Python 2.7 and Python 3.6.


We are always happy to receive code contributions, ideas, suggestions and problem reports from the community. Spend some time taking a look around, locate a bug, design issue or spelling mistake and then send us a pull request or create an issue.

Thanks in advance for your efforts, we really appreciate any help or feedback.
