Problem getting drawings from USPTO

[amotl]

Just discovered those in the log files.

It looks like all of patimg1.uspto.gov, patimg2.uspto.gov, aiw1.uspto.gov and aiw2.uspto.gov have been decomissioned.

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.

Application

Previous URL: http://aiw1.uspto.gov/.aiw?Docid=20220110447&idkey=NONE New URL: https://pdfaiw.uspto.gov/.aiw?docid=20220110447&SectionNum=2 Direct access: https://pdfaiw.uspto.gov/47/2022/04/011/2.pdf

Publication

Previous URL: http://patimg1.uspto.gov/.piw?Docid=05123456&idkey=NONE New URL: https://pdfpiw.uspto.gov/.piw?docid=05123456&SectionNum=2 Direct access: https://pdfpiw.uspto.gov/56/234/051/2.pdf

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

Hi again.

a49eeae34d has a fix for this issue, and b0d8825cb 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.
