Guyzar LLC v. Heineken U.S.A., Inc. DC

A couple of months after its last wave of suits ended, Guyzar LLC, an apparent affiliate of monetization firm IP Edge LLC, has filed another one. The NPE has sued AirBNB (1:18-cv-01256), America Movil (TracFone Wireless) (1:18-cv-01258), eBay (Stubhub) (1:18-cv-01257), and Nike (1:18-cv-05599) over the use of the OAuth protocol on their websites. The sole patent-in-suit generally relates to using a separate certification server to authenticate a first server without revealing confidential information about the user. While seeking a default judgment against a defendant in the last round, also targeted for its website operation, Guyzar—ordered to justify a $75K damages ask untethered to either a lost profits or reasonable royalty theory—voluntarily dismissed the case instead.

Guyzar LLC, an apparent affiliate of monetization firm IP Edge LLC, has revived its website login campaign after the last of its previous cases was dismissed in August. The NPE’s latest complaints, against 360Training.com (2:17-cv-00697), Al’s Formal Wear (2:17-cv-00698), Glasses USA (1:17-cv-07906), Executive Gift Shoppe (1:17-cv-07904), and Nikon (1:17-cv-06016), bring the total number of defendants in its sole campaign, launched in late 2015, to more than 75. The new defendants are accused of infringing a single web authentication patent through the use of the OAuth protocol on their websites.

Apparent IP Edge LLC affiliate Guyzar LLC has filed another half dozen cases, bringing the total number of defendants in the litigation campaign that it launched in late 2015 to over 70. The new suits accuse Genesco (2:17-cv-00361), Olympus (2:17-cv-00362), Sony (2:17-cv-00363), Zinio (2:17-cv-00364), Zoho (2:17-cv-00365), and Zoosk (2:17-cv-00366) of infringing the sole patent-at-issue in the campaign (5,845,070) through the use of the OAuth or OAuth 2 protocols on their websites. The ‘070 patent generally relates to using a separate certification server to authenticate a first server without revealing confidential information about the user.
