Purpose: The invention relates to a method and system for retail checkout of purchased articles. Customers select articles from a display of samples; the articles are automatically retrieved from a product stocking area, placed in an article accumulating area, and provided to customers after pre-check and finalizing check-out operations.

Plain-language scope (from the supplied text): The described method includes: (a) providing identification by a customer; (b) viewing samples of items in a display area; (c) entering selection of a desired item via selection means associated with the display area; (d) entering a desired quantity via quantity means; (e) repeating steps (c)–(d) for additional items; (f) performing a pre-check operation; (g) receiving an itemized, totaled receipt with identification number and account verification; (h) retrieving selected items from a product stocking area and assembling them in an item accumulating area; (i) checking out at a checkout station; and (j) receiving the purchased items. The display area has individual compartments for actual samples, with selection means employing vertical and horizontal values associated with rows and columns of compartments. The facility may include display panels, aisles, a pre-check terminal station, product stocking area, order accumulation area, conveyor, finalizing terminal, and a vehicle check-out area through which automobiles move from "zone 1" to "zone 2." A wireless-transceiver-based queuing arrangement is mentioned to serve customers on a "first arrived, first served" basis.

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.
