Purpose
The invention relates generally to shopping and advertising. It addresses the problem that product information in stores is limited to small on-package print and shelf signs, which are general rather than shopper-specific and require time-consuming comparisons. The system delivers supplemental product information at the time and place of article selection, and lets manufacturers target promotions and discounts to influence those decisions.
Plain-Language Scope
The disclosed system comprises an interactive source of supplemental information about articles in a shopping venue, plus a plurality of interactive, mobile apparatus that shoppers carry through the venue. Shoppers transmit queries to the source and receive information useful for evaluating articles; at least some received information can be formulated to influence selection decisions. Optional features described include: a speech interface (microphone/speaker or headset) with speech recognition and text-to-speech engines; a graphical interface with display and tactile input (touch screen or buttons); a bar code scanner; an artificial intelligence unit for evaluating queries; communication with a point-of-sale (POS) system; a base station housing the interactive source with transceivers and processors; a supplemental database relating to personal shopping preferences; and mounting on a shopping cart.

Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
