Purpose: The invention generally relates to peripheral input devices for computers and video game consoles. Its fundamental object is a hand-operated game pad controller plus a plurality of modules that may be releasably joined to the game pad to add functionality appropriate to the game being played. A more specific object is a novel two-hand operated controller that includes a removable mouse module for axis directional control while also incorporating a game pad device into a single integrated device, thereby eliminating the need for the keyboard in a mouse/keyboard combination.
Plain-language scope: The background contrasts existing input devices: a flight yoke offers slow, steady, precise aiming but poor quick-reflex aiming; a mouse/keyboard setup offers excellent quick-reflex aiming but the keyboard is a poor gaming input; and handheld game pads offer good fingertip button access but weak aiming. The mouse and hand-operated joystick require a stable flat surface, while handheld game pads are strictly hand-supported and work away from such surfaces. The described invention addresses this by letting a user reconfigure a two-hand controller with releasable modules depending on the game.
What the excerpt does not establish: The excerpt is explicitly partial ("[Excerpt only; consult the source for omitted text.]"), so the complete claim set, dependent claims, full specification, drawing descriptions, and any listed prior-art references are not available here. The overview above rests only on the supplied background and objects; no claims are quoted because none appear in the excerpt. Litigation, ownership transfers, validity, and prior-art analysis were not researched and are not addressed.

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.
