That looks like a patent application, not a grant. You can't claim you have a patent on this yet.

I'm not sure why the application page rather than the grant page is the one turning up in Google's results, but the patent was granted. It is US Patent number 7,126.691, issued October 24, 2006.

Ah. Here's the link: https://www.google.com/patents/US7126691

Not in my experience. It would give me “select cars until none are visible” and it would be replacing the last car by another one for a long time. Then, when there are finally none, it would just offer another captcha, such a as “click on storefronts until there are none”. And so on and on

Same here. I'm starting to wonder if they're doing that on purpose to profile real users according to how fast they solve multiple captchas, say by measuring reaction times between every click on a "car", or to refine their anti bot algorithms by doing a deeper analysis of real user behavior. Whatever their intentions are, it's frustrating.

My guess is that most of the "automatic" stuff is done using cookies and other fingerprinting techniques. In safari I hit the longer captchas far more often than in chrome, and it is quite possible that it is because of the ad blocking tech inside.

Gotta love the patent system. Reading the summary made my eyes roll so far into the back of my head. Basically, they've patented shadow-banning via CAPTCHA. And I'm left also wondering if they've taken the "that's not a bug, it's a feature" meme to a whole new level. I've run into the scenario described by this patent on a few occasions over the last year. I'll be given a CAPTCHA on Google's search results page that…

The patent isn't from Google, it's only listed on Google Patents. Original Assignee: Juniper Networks, Inc.

D'Oh! Thanks for the correction -- somewhat changes my response a bit!
