PatZilla is a modular patent information research platform and data integration toolkit. It provides access to multiple data sources, like the OPS service from EPO, and other professional fulltext patent databases.
The system features an efficient user interface for convenient data exploration in its standalone version. Its software components and interfaces can also be used to build different kinds of vendor solutions.
Currently, PatZilla powers Europatent PATOffice Navigator and Serviva PATselect 4.0.
Project status:
Code status:
- Multiple data source APIs. Connect to different patent search services and APIs for the acquisition of bibliographic-, fulltext-, image-, and pdf-data.
- Graphical 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.
- Command line interface. Functionality for acquiring and processing raw patent data
is conveniently available on the command line using the
patzillacommand. It can be used to run ad hoc inquiries to the system and the upstream data sources and to build custom scripted solutions and simple automations. - HTTP API interface. Through the extensive REST API, all functionality is easily available to 3rd-party systems. Deep integration has no limits.
- Dossier management. Manage different collections of patent documents and apply ratings and comments.
- Sharing. Well-designed collaboration features allow efficient sharing of information with your colleagues and partners, even across the boundaries of in-house systems.
- Multi-tenancy. The software can operate on behalf of different vendors with individual custom branding.
A picture says a thousand words.
The CLI interface offers access to the machinery of PatZilla on your fingertips.
Note that most of the following commands will need appropriate configuration of corresponding access credentials. For more information, please follow up reading the cli documentation.
Examples using EPO/OPS:
# Display usage information of EPO/OPS in JSON format. patzilla ops usage # Submit search query to EPO/OPS, within "title" and "abstract" texts. patzilla ops search "txt=(wind or solar) and energy" # Inquire information about pages and images of full document. patzilla ops image-info --document EP0666666B1 # Acquire first page of patent document in PDF format. patzilla ops image --document EP0666666B1 --page 1 > EP0666666B1-page1.pdf # Acquire first drawing of patent document in PDF format. patzilla ops image --document EP0666666B1 --page 1 --kind FullDocumentDrawing > EP0666666B1-drawing1.pdf
Example using IFI CLAIMS:
patzilla ificlaims search "text:(wind or solar) and energy"
The search demo will run a fixed query on EPO/OPS and display the results.
txt=(SS7 or (telecommunication or communication or comunicación) or (mobile or Mobilfunknetz) or (network or (security or Sicherung))) and pa=(mobil or kommunikation) and cl=(H04W12/12 or H04L63/0281 or H04L63/0414) not pn=(CN or CA or JP)
You will be able to step through result pages and display fulltext- and family-information, but running custom queries will be disabled.
The numberlist demo will display the patent documents DE102011075997A1, DE102011076020A1, DE102011076022A1 and DE102011076035A1. This is a showcase about how to integrate a link to a list of patent documents into own applications. The nasa-public-domain demo is a similar demo, it displays a number of patents of the Public Domain NASA technologies.
The document view demo will display the patent document EP0666666A2 without any control elements. This is a showcase about how to embed the document view into own applications or how to directly link to single documents.
PatZilla uses different API services for accessing patent information.

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.
After a project hiatus from 2020 to 2022, the code base is getting a refresh, many software tests have been added, and the aim is to finish migration to Python 3 within the end of the year.
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.
