Installation

pip install patent_client

If you only want access to USPTO resources, you’re done! However, additional setup is necessary to access EPO Inpadoc and EPO Register resources. See the Docs.

Documentation

The easiest way to get started is with Patent Client Examples. The examples repository has a list of Jupyter notebooks showing application examples of the patent_client library.

Docs, including a fulsome Getting Started are available on Read the Docs.

SUPER QUICK START

To use the project:

# Import the model classes you need
>>> from patent_client import Inpadoc, Assignment, USApplication

# Fetch US Applications
>>> app = USApplication.objects.get('15710770')
>>> app.patent_title
'Camera Assembly with Concave-Shaped Front Face'

# Fetch from USPTO Assignments
>>> assignments = Assignment.objects.filter(assignee='Google')
>>> len(assignments) > 23000
True
>>> assignment = Assignment.objects.get('47086-788')
>>> assignment.conveyance_text
'ASSIGNMENT OF ASSIGNORS INTEREST'

# Fetch from INPADOC
>>> pub = Inpadoc.objects.get('EP3082535A1')
>>> pub.biblio.title
'AUTOMATIC FLUID DISPENSER'

# Fetch from EPO Register (NOTE: This is broken right now :( )
#>>> epo = Epo.objects.get('EP3082535A1')
#>>> epo.title
#'AUTOMATIC FLUID DISPENSER'
#>>> epo.status
#[{'description': 'Examination is in progress', 'code': '14', 'date': '20180615'}]

Other Languages

Merely as a way to explore other languages and technologies, I have built a few (partial) ports of this library to other languages:

• patent_client_js - ES6 Javascript (PEDS / PTAB / Assignments support (ASYNC!))

• patent_client_java - Java (Ptab API only)

• patent_client_scala - Scala (Ptab API only)

• patent_client_ruby - Ruby (Nothing Works Yet)

Development

To run the all tests run:

pytest

A developer guide is provided in the Documentation. This project is narrowly scoped to only public documented API’s available without charge (at least for moderate usage). Scrapers of HTML websites are not permitted. But PR’s to add support for new API’s are more than welcome.

Pull requests welcome!
