To use the project:

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

# Fetch US Patents with the word "tennis" in their title issued in 2010
>>> pats = PatentBiblio.objects.filter(title="tennis", issue_date="2010-01-01->2010-12-31")
>>> len(pats) > 10
True

# Look at the first one
>>> pats[0]
PublicationBiblio(publication_number=7841958, publication_date=2010-11-30, patent_title=Modular table tennis game)

# 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
