PRODUCTS AND THE PATENTS THAT COVER THEM
United States patents.
Each product below is covered by the patents listed with it. A patent may cover some features of a product and not others; a product may include features that no listed patent covers. The claims of each patent determine its scope. Patent numbers link to the public record at Google Patents.
Alice®, Alice® OnBoard and Alice® Avatars
Personalized and targeted media: selecting, customizing and delivering content for the people present, including selection by audience context and, with the visitor’s consent and where the installation is configured for it, by recognition and continuity (the capability that lets Alice® Avatars recognize the visitors they serve). Alice® OnBoard delivers concurrent personal presentations on a visitor’s own device using the same parallel-media methods as Lory®. In-venue location is included where configured.
