Problem getting drawings from USPTO about patzilla

[aghster]

As it seems, USPTO does not provide TIFF images any longer, but only PDF:
https://patft.uspto.gov/netahtml/PTO/help/images.htm (see "Notices")

Instead of loading a TIFF from http://aiw1.uspto.gov/.aiw?Docid=20220110447&idkey=NONE, you will probably have to load a PDF from https://pdfaiw.uspto.gov/47/2022/04/011/1.pdf.

Apparently, for a Docid "abcd0efghij" the URL to access a PDF of the n-th page is: https://pdfaiw.uspto.gov/ij/abcd/gh/0ef/n.pdf

Hi @aghster,

thanks. Nice to see you again. You are absolutely right. Currently, I am trying to figure out if I can trust the observation that "Drawings" are always on section 2 / page 2. Can you spot any contradicting samples?

With kind regards,
Andreas.

Summary

I am picking two arbitrary samples here. The application is fairly new.

I found a contradicting example. Within the document US10194689B2, drawings at section 2 ¹ will only start on page 5 ².

Hi again.

a49eeae has a fix for this issue, and b0d8825 covers it with corresponding test cases. Both are part of #49. Thank you again!

With kind regards,
Andreas.

Dear @aghster,

USPTO PatFT and AppFT servers have been decommissioned recently, see #61.

With kind regards,
Andreas.
