USPTO AWS Web Application Firewall breaks Patent Public Search Functionality about patent_client HOT 9 CLOSED

The WAF appears to be gone, and I've gotten it working by using the HTTPX library to support HTTP/2

The notes suggesting that Public Patent Search no longer works have been removed!

Version 3.2.7 includes these fixes!

The USPTO implemented a AWS Web Application Firewall as an anti-bot measure that is currently breaking this feature. I don't have a good workaround until the USPTO decides to offer an actual PublicSearch API. Sorry!

Updated docs to indicate that this feature is broken, and updated examples. Will keep this open on the off chance that I can find a workaround.

Is it just me or does that actual web site for Patent Public Search not working? Going to this URL for me just shows Forbidden in general.

I think what you're experiencing is another side effect of the WAF. If you try to use this library a few times on Patent Public Search, your IP gets blacklisted for some short period of time. If you turn on a VPN, or wait a few hours, the Forbidden notice goes away.

I should probably hard-disable the PPS functionality in this library to prevent that from happening to other people...
