Purpose and Plain-Language Scope:
Based solely on the supplied excerpt, the patent concerns a technique for effectively providing audio information in a vehicle. The prior-art keywords listed—"option," "user," "interface," "screen," and "vehicle"—indicate the disclosure relates to a user interface presenting options on a screen within a vehicle context. The classification codes cover vehicle instrumentation and dashboard arrangements (B60K35/00 series), including input arrangements from user to vehicle (B60K35/10), output arrangements from vehicle to user (B60K35/20), visual output such as matrix displays (B60K35/21), and display screens (B60K35/22). Additional classifications relate to heating/cooling/ventilating control systems with displays or voice simulators (B60H1/00985) and suspension control combined with other vehicle control systems (B60G17/0195). This suggests the audio information technique may integrate with various vehicle systems and user-facing displays.

What the Excerpt Does Not Establish:
The supplied text is heavily excerpted and does not include the patent's abstract, specification, claims, or detailed description. It does not establish the specific technical steps of the claimed audio-information technique, the exact hardware or software architecture, the relationship between audio and visual outputs, or the precise scope of any claim. No litigation, ownership transfer, validity, or prior-art analysis is provided or inferred here. The classification list is extensive but appears truncated, so the full scope of technical categorization is not established.

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
