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

PatZilla: Patent information research for humans

About

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.

• Code status:

  

  

Features

• 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 patzilla command. 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.

User interfaces

Graphical user interface

A picture says a thousand words.

Command line interface

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"

Demos

• 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.

Data sources

PatZilla uses different API services for accessing patent information.

Primary data sources:

• EPO/OPS
• DPMA/DEPATISnet
• IFI Claims
• MTC depa.tech

Auxiliary data sources:

• USPTO/PATIMG
• CIPO

Getting started

Getting started with the software or deploying it yourself is quite easy if you are familiar with Python or Docker. See the install documentation page about how to install, configure and run PatZilla.

History

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.

patzilla's Issues

Support Docker-based development sandboxes

Building on top what @aghster already contributed the other day, I already mentioned at #6 (comment) that

there might be another type of Docker container in the future which will give you a complete development sandbox setup.

and in #8 (comment), we again found that this would be a good option to have.

DEPATISnet data source adapter broken after upstream layout updates (June 14th, 2022)

Hi there,

on June 14th, 2022, the DPMA will deploy an update to the public-facing DEPATISnet systems.

DEPATISnet will have a new layout from 14 June 2022.
The pages have been streamlined.

-- https://depatisnet.dpma.de/DepatisNet/depatisnet?window=1&space=menu&content=assistent&action=aktuelles&switchToLang=en#a52

This breaks the corresponding client adapter dpma/depatisnet.py. The regression has been detected by our monitoring systems at ~18 o'clock on June 13.

With kind regards,
Andreas.

USPTO PatFT and AppFT servers decommissioned on September 30, 2022

Hi there,

following up on #48, we wanted to report that the USPTO introduced PPUBS, and deprecated PatFT, AppFT, PubEAST, and PubWEST ¹.

With kind regards,
Andreas.

Unexpected HTTP 4XX in case of server issue

Hello,

Page: /navigator/
IMHO It is better to have HTTP 5XX answer to frontend (for example 500) if search back-end answered with HTTP 401.
Now: back-end answers with HTTP 404/400. But client request can be fully valid, it is just issue with server config for example.

Data lost

Hello,
I have done a search last friday, but today I don't find my file.
In Patzilla navigator, I created a project, then performed my searches and selected some documents.
They was listed in collection of documents area.
Today, I restart the computer and the server, but the interface is virgin like the first day. In projects collection, I have only "ad-hoc" project with 0 documents.
The service mongod is running.
I just installed genghisapp to browse the content of mongodb, I found the database patzilla_development but there is no collection in it.
I run patzilla as user with the sequence :

source .venv27/bin/activate
pserve patzilla.ini

Are my data saved? Where? How can they be restored?
I'm running Mageia 7 with mongodb-4.1.4

User interface is broken when displaying document details

Hi there,

when starting PatZilla in development/sandbox mode, I am observing a few glitches.

First, something is wrong with the fonts on the data source chooser.

Then, as already discovered and reported by @papoteur-mga at #68 (comment), it looks like the document details are not displayed at all, and, in the same manner, the document details chooser also does not work. The problem can easily be revealed by conducting a simple query.

Bummer! I will try to look into this on the weekend, or next week.

With kind regards,
Andreas.

How to configure data source DEPATISnet

Trying to figure out how to configure DEPATISnet as a data source. So far IP-Navigator always tries to collect from OPS no matter if it is mentioned in the patzilla.ini or not.

So there seems to be no difference whether patzilla.ini reads:

    datasources = ops, depatisnet, depatech

or datasources = depatisnet, depatech

How do I force IP-Navigator to search DEPATISnet and how would I configure this in the .ini?

Thanks!

PatZilla does not serve requests when started in development mode

Hi there,

following up on the report #51 by @think-nice-things, we tried to reproduce the problem. We installed the software with:

virtualenv --python=python2 .venv2
source .venv2/bin/activate
pip install patzilla
pip install 'urllib3!=1.25.0,!=1.25.1,<1.26,>=1.21.1'  # Just a fix to adjust some dependency woes.

Then, we created the configuration file patzilla.ini

patzilla make-config development > patzilla.ini

and adjusted a single line, adding the depatech data source like:

[ip_navigator]
datasources = ops, depatisnet, depatech

With that, PatZilla seems to start successfully.

pserve patzilla.ini

Report with bibliographic data

Hello,
I tried different exports after some searches.
I would expect to have a report (PDF or ODT format) with the collection of bibliographic data, but didn"t found that.
Have I missed something?

How to install Patzilla on Ubuntu 23.04 ?

Hello,
I have failed to install using docker, docker-compose, or Linux installation following instructions at https://docs.ip-tools.org/patzilla/install/linux-macos.html#install-linux-macos

Fix normalization of USPTO document numbers for granted patents

@aghster spotted an issue with normalizing numbers for USPTO appropriately:

I think you will have to pad document numbers for granted patents with leading zeros to ensure that the length is 8 for patents preceeding US 10,000,000 B2. However, normalize_patent_us() does not seem to do this.

See also [the kind of reference implementation] PatentsViewApp.openPDF().

Support Python 3

2020: Python 2 is dead. Long live Python 3!

@frankheider already chimed in (thanks again!) to add basic Python 3 support within [1]. However, this is just a start. The codebase will have to be converted completely and the functionality has to be checked for any quirks eventually coming from this transition.

Update list of OPS fulltext countries

Dear @aghster,

thank you again for your contribution #3 submitted the other day. In the OPS manual 1.3.16 ¹, I observed the following change log items since I've looked at it the last time:

• 2019-05-07 1.3.10 Updated fulltext collection.
• 2019-09-05 1.3.15 Updated the fulltext country code list.
• 2020-09-14 1.3.16 Correction to countries list.

Maybe it is not too difficult to figure out what has changed here, and converge that into a patch, if necessary.

With kind regards,
Andreas.

New Espacenet version will probably require adaptations

Hi,

the EPO has recently released a beta of the upcoming new Espacenet. When the current Espacenet will be replaced by the new one, this will probably require some adaptation of all services that obtain their data by crawling Espacenet.

I just wanted to give you a heads up.

Grouping by family with OPS database

Querying with DPMA database allows to group documents per family.
However, this is not possible today with the OPS Database.
Why this limitation?
Is it because it is better to query DPMA?
Or the feature is not yet developped?

depa.tech doesn't work

Hi,

I installed patzilla as from pip (0.169.3).
The data source ops works nicely but I didn't manage to use depa.tech.
I've aquired a depa.tech account.

The relevant config entries look like this:

[ip_naviator]
datasources = ops, depatisnet, depatech

# [datasource:depatech]                                                                                                                                                                                                                                                                                                                                  
api_uri      = {depatech_api_uri}                                                                                                                                                            
api_username = {depatech_api_username}                                                                                                                                                       
api_password = {depatech_api_password}     

where I used the credentials as supplied by depa.tech.

Still depa.tech doesn't appear and for example in the web interface I don't get the depa.tech button.

Anything I'm missing?

PatZilla croaks with “HTTPBadGateway: Could not connect to OPS servers”

After installing PatZilla in development mode on a fresh Ubuntu 18.10 box, customers are reporting a problem to us. While PatZilla starts fine and is apparently properly configured, it bails out when actually accessing the OPS services with this exception:

  File "/home/develop/patselect-dev/ip-navigator/patzilla/access/epo/ops/client.py", line 192, in request
    raise error
HTTPBadGateway: Could not connect to OPS servers.

Add Open Office to Docker image

Regarding the topic about satisfying the dependency to OO in Docker from #5, @aghster said:

Also, I do not think that OO is actually required, since according to @amotl it just serves to do "some rendering for specific export artefacts".

Yes, the export subsystem offers an Excel report and unoconv is really just used for converting this to a PDF file. PatZilla will perfectly run without this.

Unfortunately, there seems to be no pre-built unoconv package for Alpine Linux. Therefore, one would have to install unoconv and include the required LibreOffice or OpenOffice libraries manually.

unoconv can be acquired through PyPI [1]. Would LibreOffice or OpenOffice be available on Alpine?

Improve documentation re. workstation setup vs. development setup

Hello,

I just tried the application patzilla 0.162.0.

As soon I try to open the site, I get a server error. In console message, it seems that templates/urlcleaner.js is claimed but not present. Indeed, I found only templates/urlcleaner.min.js.

I'm on a Mageia distro. I set a virtualenv, then used pip to get the installation. This worked. Then I created a patzilla.ini as development config.

Launching the server is OK.

  File "/home/yves/.venv27/lib/python2.7/site-packages/mako/runtime.py", line 804, in _lookup_template
    raise exceptions.TemplateLookupException(str(compat.exception_as()))
TemplateLookupException: Can not locate template for uri 'patzilla.navigator:templates/'

I never tried it before.

I understand that the docker-compose means of installation is probably not supported yet, just wanted to point out the issue. (Also had to add a couple of things to the docker files to get things to work, happy to make a pull request when desired)

Problems installing in sandbox mode, and migration to Python 3

I'm trying to launch Patzilla in sandbox mode.
However, when I connect the page http://localhost:6543/navigator/ I get a blank page. In debug console, I found:

Uncaught Error: Module build failed (from /home/yves/patzilla/patzilla/node_modules/sass-loader/lib/loader.js):
Error: Missing binding /home/yves/patzilla/patzilla/node_modules/node-sass/vendor/linux-x64-83/binding.node
Node Sass could not find a binding for your current environment: Linux 64-bit with Node.js 14.x

Found bindings for the following environments:
  - Linux 64-bit with Node.js 11.x

This usually happens because your environment has changed since running `npm install`.
Run `npm rebuild node-sass` to download the binding for your current environment.

However, the file /home/yves/patzilla/patzilla/node_modules/node-sass/vendor/linux-x64-83/binding.node exists.
On Internet, I found multiple answer to rebuild node-sass module, but after tenth rebuild, I convinced that something else is the cause.
I have system node at version 14.25.3, thus I don't understand why it says Found bindings for the following environments: - Linux 64-bit with Node.js 11.x
