Download patent as pdf #164

Closed prana2023 closed 2 months ago

prana2023 commented 2 months ago

I would like to download the patent as a PDF using patent IDs. I am using the following code but it is not working:

from patent_client import Patent

patent = Patent.objects.get("11478533") patent.download_images(path='/ub33/Downloads/')

Do I need an API key to access ppubs uspto ?

See the error stack I get:

File "/Users/ub33/PycharmProjects/tpp/dataprocessing/Patent.py", line 4, in patent.download_images(path='/ub33/Downloads/') File "/Users/ub33/PycharmProjects/tpp/venv/lib/python3.9/site-packages/patent_client/_sync/uspto/public_search/model/document.py", line 205, in download_images return public_search_api.download_image(self, path) File "/Users/ub33/PycharmProjects/tpp/venv/lib/python3.9/site-packages/patent_client/_sync/uspto/public_search/api.py", line 173, in download_image response.raise_for_status() File "/Users/ub33/PycharmProjects/tpp/venv/lib/python3.9/site-packages/httpx/_models.py", line 761, in raise_for_status raise HTTPStatusError(message, request=request, response=self) httpx.HTTPStatusError: Client error '404 Not Found' for url 'https://ppubs.uspto.gov/dirsearch-public/print/print-process' For more information check: https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/404

FYI: I cannot repeat this error, it works well for me. Maybe it was an upstream error at USPTO (maintenance or whatever)?

Do you still have the issue?

For the record, this API is pretty flakey. It isn't an API per-se, since I'm automating the Patents Public Search interface for it, and it changes frequently without notice, and has some backend instability. If it is throwing a 404 error, it's probably a USPTO issue. If you consistently have the issue and it seems like it's a patent_client library, I'm happy to take a deeper look!
