Patent Overview — US 8,112,323 B2

Title: Procurement requisition processing method and system

Patent number / application: US 8,112,323 B2; Application US 11/867,084

Assignee: International Business Machines Corporation (original and current assignee listed)

Inventors: Macam S. Dattathreya; Russell Thomas White, Jr.

Key dates: Filed 2007-10-04; priority date 2007-10-04 (as listed); published as US 2009/0094130 A1 on 2009-04-09; granted 2012-02-07. Legal status shown as "Expired – Fee Related," with an adjusted expiration of 2030-12-07 (status and dates are described in the source as assumptions, not legal conclusions).

Purpose: The invention relates to "a method and associated system for configuring available purchase types for items available for purchase." It addresses the stated problem that modifying a process for requesting items is complicated and inflexible, that a user requesting items may lack the ability to associate items with external factors, and may be limited by an inability to modify the process.

Plain-language scope: The disclosed system generates and modifies three profile types—entity/company profile, catalog profile, and user profile—and uses a database table of "purchase types." Predetermined purchase types are inserted into the table; entity and catalog profile GUIs are modified to let administrators specify allowable purchase types; user profiles allow default purchase types based on the user's owning company's allowable types. Based on a user's company and selected purchase type, a shopping process provides appropriate catalogs. The stated advantage is that purchase types for items are configurable without requiring software application code changes each time a new purchase type is introduced; a "purchasing type" entity appears in company, user, and catalog profiles. The patent also describes a purchasing method, a computing system, a computer program product, and a process for supporting computer infrastructure.

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.
