Title: Apparatus and method for automatically refreshing a display of a telephone
Patent number / application: US8903067B2; application US11/472,613
Assignee (per source): Original assignee TP Lab Inc. The source lists current assignee as Lab Technology LLC (noted as possibly inaccurate). Per instructions, ownership transfers are not addressed here.
Key dates (as listed): Prior art date and filing date 2006-06-22; publication date 2014-12-02; adjusted expiration 2031-07-23; legal status listed as Active. The source notes that legal status and dates are assumptions, not legal conclusions.
Inventor: Shin Cheung Simon Chiu
Purpose: The invention "relates generally to telecommunications, and more specifically to apparatus and methods for automatically refreshing a display screen of a telephone." The stated problem is that a telephone's display and navigation keys force users to "navigate through many menu displays in order to find a desired service," given the many available services (personal communication, directory, information, and commercial services such as voice messaging, yellow pages, stock quotes, weather, traffic, fund transfer, ticketing, or merchandise ordering).
Plain-language scope (from the excerpt): The patent addresses automatically refreshing a telephone's display so that the services shown reflect what the user is likely to want. The excerpt indicates the refresh can depend on usage patterns — users "often access the same services at the same time every day," use some services more routinely, and may access certain services "depending on their location," such as on public transportation or in a mall. A worked example describes a working single parent using a home phone for weather, traffic, school announcements, voice messages, and news, and a local restaurant directory to order take-out. Classifications include location-based services (H04W4/02, H04W4/029) and user interfaces adapted to specific conditions according to geographic location (H04M1/72457).
Not established by the excerpt: The excerpt omits the claims, abstract, and most of the description. It therefore does not establish the specific claimed apparatus/method steps, the exact refresh triggers or algorithms, claim scope or breadth, validity, or the prior art.

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

Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
