Purpose. The patent addresses roulette gaming, specifically side bets and apparatus enabling novel roulette gaming methods. The background notes that players seek new, more interesting ways to play roulette, particularly where rewards or winning odds may be enhanced. The definitions describe a roulette-based wagering system with a physical roulette wheel, a source of multiple drop balls including at least two balls of different colors, and a selection system that selects a single drop ball for a wagering event. A preferred automated version uses a processor with a random number generator configured to control most aspects of the wagering event.
Plain-language scope. In the described side-bet flow, a multiplier may be randomly selected from a group of fixed multipliers for a payout on a wager; a number and associated color may be randomly generated; the wager is resolved by comparing the randomly generated number to one from the immediately preceding round. A payout is paid when the numbers match, equal to the wager multiplied by the randomly selected multiplier; when they differ, the wager amount is collected for the house. The excerpt also describes ball-storage areas holding first and second colored balls, and a processor causing the selection system to randomly select only one ball for the next event.
What the excerpt does not establish. It does not provide the full claims or claim scope, the complete specification, the number of claims, or the exact claim language. The listed classification codes and prior-art keyword list are indexing labels, not findings. Because the source is explicitly excerpted and omits text, any details beyond those quoted above—including figures, dependent-claim limitations, and the full description—are not established here. Assignee entries reflect recorded assignments only; no independent verification was performed, and no litigation, validity, or prior-art analysis is offered or implied.

PTAB challenges
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.
Extensions
Patent term adjustments, term extensions, continuations, divisionals, family members, and expiration dates.
Derivative works
Defensive disclosure: derivative variations of each claim designed to render future incremental improvements obvious or non-novel.
