Error while using example function

Example:

from patent_client import Inpadoc, Assignment, USApplication, Patent
# Import the model classes you need
# Fetch US Patents with the word "tennis" in their title issued in 2010
pats = Patent.objects.filter(title="tennis", issue_date="2010-01-01->2010-12-31")
len(pats) > 10

For the Patents endpoint, the issue appears to be related to the deprecation of the PatFT/AppFT endpoints, currently being addressed in #63.

For the Inpadoc endpoint, I have opened a new issue #76 with a descriptive title while I investigate the issue.

Thanks!
