Website User Authentication Campaign Hits Facebook
New Patent Litigation
Facebook (4:19-cv-04355) has become the fifth defendant sued in the new litigation campaign of Utah plaintiff TransactionSecure, L.L.C., which hit DeviantArt, Fitbit, Microsoft (GitHub), and Stripe earlier in July. The defendants are accused of infringement through the use of the OAuth 2.0 protocol, a user authentication framework, on their respective websites, in this new case focusing on its use by Instagram. The asserted patent broadly concerns authenticating a user’s identity using a “trusted entity” with a repository that holds the user’s personal information.

New Campaign Targets OAuth 2.0 Protocol for Website User Authentication
New Patent Litigation
TransactionSecure, L.L.C. has launched a second litigation campaign over a decade after its first one ended. The Utah plaintiff accuses DeviantArt (2:19-cv-05836), Fitbit (3:19-cv-04075), and Stripe (3:19-cv-04052) of infringing a single patent generally related to authenticating a user’s identity using a “trusted entity” with a repository that holds the user’s personal information. (TransactionSecure also filed a case, since removed from PACER, over the same patent against Microsoft (GitHub) (3:19-cv-04050).) At issue in each case is the defendant’s use of the OAuth 2.0 protocol, a user authentication framework, on its website.
