Patent Overview — US6014090A
Title: Method and apparatus for delivering local information to travelers
Patent number / application: US6014090A; application US08/995,623
Inventors: Kenneth H. Rosen; Steven Charles Salimando
Original assignee: AT&T Inc (per the supplied page, with current assignees listed as Google LLC and AT&T Properties LLC)
Dates: Priority/filing date 1997-12-22; publication/grant date 2000-01-11; anticipated expiration 2017-12-22
Status: Expired – Lifetime
Purpose: The invention gives a user of a mobile communication system geographically localized information that is time-dependent, so that a traveler can receive information that is up to date and relevant to the traveler's location, at a level of detail the user controls.
Plain-language scope: A geographic location identifier associated with the mobile communication system's location is received. An address of a resource server, which stores time-dependent, geographically localized information, is associated with that identifier, and the address is sent to the mobile communication system. The geographic location identifier may come from a GPS receiver, a bar code scanner reading a fixed bar code, or user-observed mile markers/channel markers. The identifier can be translated into a URL or into a radio frequency for tuning an associated radio, or can itself be the resource server address. Information may be delivered over a wireless link, including audio content via a mobile phone. A list of multiple resource servers related to the location identifier is contemplated. System elements include a telecommunications network, a resolution server (processor, memory, port), resource servers, and a mobile communication system (transceiver, geographic location device, user interface device).

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.
