Patent Overview — US7251621B1

Title: Method and apparatus for the home delivery of local retail e-commerce orders

Assignee/Inventor: Individual (original assignee listed as Individual); inventor Weiwen Weng.

Key dates (as listed): Priority date 2006-02-03; application US11/617,989 filed 2006-12-29; granted and published 2007-07-31; anticipated expiration 2026-02-03. Legal status: Expired – Fee Related.

Purpose: The patent addresses high consumer delivery costs in e-commerce. It empowers members of the general population ("patrons") to deliver retail-store orders to buyers more cost-effectively than conventional home-delivery services, using deviations from a route the patron would already travel. The description frames "local" as a network of sellers, buyers, and patrons within about 50 miles of a population or commerce center (potentially far smaller in dense cities), and states the approach applies to any category of e-commerce goods (electronics, groceries, clothing, appliances, and others).

Plain-language scope (from the excerpted text): The disclosed methods, systems, and computer data signals match pending e-commerce orders with a patron whose acceptable delivery criteria are satisfied. These criteria include acceptable deviation criteria (e.g., added distance under 1 mile or added time under 5 minutes) and acceptable order criteria (e.g., weight under about 20 pounds or fewer than 3 bags). Separately, buyers impose acceptable patron criteria—such as a minimum number of prior deliveries, positive feedback, or proximity within degrees of connection in a trust network (the text references third-party ratings and networking sites). The excerpt also describes cost concepts (cost of travel, total travel cost, true travel cost), and systems with data-storage media and client/server matching calculations executed substantially on the internet. Figures 2 and 3 concern a component diagram and travel/delivery efficiency.

What the excerpt does not establish: It does not supply the full claims, complete specification, drawings, or prosecution history; nor does it provide claim-by-claim scope, exact step ordering, or all limitations.

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.
