Purpose (per the excerpt): Existing mobile devices have limited display and navigation capacity, so PC-oriented personalized pages can present more information than a user wants to page through on a phone. The patent addresses presenting information on mobile communications devices in "desirable and contextually relevant ways."
Plain-language scope (per the excerpt): The information presented at a user's mobile device is contextually based on the device location, user identity, time of day, aggregated information-based web portal usage statistics, and personal status and presence information. Presentation is controlled by "template-like lenses" — for example, geographic lenses (communities, cities, states, nationalities) and venue lenses (sporting, recreational, educational, work, national parks, amusement parks). Users can build customized lenses. The service can automatically update lenses based on contextual status and presence information. Lenses accommodate profiles developed from aggregate computer and telephone usage data, so information can be presented automatically once the appropriate lens is determined.

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.
