Washington plaintiff Nobots LLC has filed suit against Alphabet (Google) (6:21-cv-01290) over the provision of CAPTCHA security products, including Google reCAPTCHA v2 Checkbox, reCAPTCHA v2 Invisible, reCAPTCHA v3, and reCAPTCHA Enterprise. The new Western District of Texas recounts a history of such products, culminating in the assertion that Google infringes two patents that Nobots pleads cover “new and improved CAPTCHA security methods” that “shift[] the burden of proof for assessing the likely user status of a computing device form the user side to the server side of the equation, by analyzing biometric and other available data of the user . . . and yielding a probability value, or confidence score, that the user is a human being rather than a bot”.
