Patent Overview — US6755741B1
Title: Gambling game system and method for remotely-located players
Patent number / application: US6755741B1; application US09/869,763, filed 2000-01-06.
Inventor / assignee: Inventor Yacob Rafaeli. Original and current assignee listed as "Individual" (the source notes listed assignees may be inaccurate).
Key dates: Priority date 1999-01-07 (assumed, per source); filing 2000-01-06; granted/publication 2004-06-29; anticipated expiration 2020-01-06. Legal status: Ceased.
Purpose: To let remotely-located players participate in real gambling games, rather than only in "virtual systems" that display a simulated game device (roulette wheel, card table, slot machine). The stated aim is to increase players' feeling and excitement of being present in a real casino and their confidence in the system's integrity "against the possibility of electronical manipulation."
Plain-language scope (from the excerpted description): A central station — preferably an actual casino — has multiple betting-type game devices involving chance, each with an electronic camera (and preferably a microphone). Remotely-located player stations each have a monitor, a speaker, and input means. Data processing means: (a) establish communication between central and player stations; (b) let a player select a game device, see what occurs there, and place a bet on an action involving chance at that device; (c) display the player's current account (continuously displayed and updated). Some game devices involve actions by a house person at the casino (e.g., card table, roulette); others involve actions by the remote player (e.g., remotely activated slot machines, remotely thrown dice). Player stations may use personal computers with downloaded software, and may include an electronic camera to transmit the player's image to a display at the player's card-table position.

AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
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
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
