US7310532B2 — Patent Overview
Title: Method of automatically updating presence information
Patent number: US7310532B2
Application number: US10/004,568
Inventor(s): Robert C. Knauerhase; Nikhil M. Deshpande
Assignee: Intel Corp (original and current assignee per the source listing)
Priority/filing date: 2001-12-05
Grant/publication date: 2007-12-18
Prior publication: US20030104819A1 (published 2003-06-05)
Status listed: Expired – Fee Related (adjusted expiration 2023-03-27); the source notes legal status is an assumption, not a legal conclusion.
Purpose: The invention addresses the burden of manually maintaining presence information. The excerpt explains that presence information may include reachability of a user through a system (e.g., an instant messaging connection) and availability state (e.g., "available" or "unavailable"). In current systems, users set presence state explicitly, and it persists until manually changed—a process the patent calls cumbersome, easily forgotten, and productive of inaccurate presence information. The invention relates generally to mobile devices and more particularly to automatically updating presence information for a mobile device.
Plain-language scope (from the excerpt): An architecture in which a presence server (160) provides services to mobile devices (140, 142, 144) over a network (110), which may connect to hotspot access points (120, 130). Mobile devices may connect via hotspots, wirelessly without a hotspot, or by hardwired connection. Networks may include Internet/IP, LAN, WAN, GPRS, cellular data, GPS, or IEEE 802.11B, among others. The presence server receives and stores presence information. Figures describe presence rules, presence information contents, and processing including determining state information. Classification includes H04W4/02, H04L67/54 (presence management), and G01S5/0027.
What the excerpt does not establish: It is explicitly marked an excerpt with omitted text, so the full claim set, complete figure descriptions, and detailed processing steps are not available here. It does not establish claim scope, validity, litigation, or ownership transfers; such matters were not researched per instructions.

No PTAB proceedings on file. This patent has not been challenged via IPR, PGR, or CBM. The absence is itself a signal — well-asserted patents eventually attract IPRs. The LLM analysis below may surface filings the ODP feed hasn’t indexed yet.
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.
