Purpose and plain-language scope (from the supplied definitions and excerpt): The invention "generally relates to IP Multimedia Subsystem (IMS) networks and, more specifically, to IMS users that use (perhaps multiple) discovered user endpoint devices." The excerpt frames this against the evolution from circuit-switched voice (BTS/RAN, BSC, MSC/GMSC, SS7 signaling, TDM) toward packet-switched data overlays and 2.5G/3G multimedia, where a handset's IP context is maintained whenever it is powered on and connected, rather than only during a call. It also notes that a defining aspect of such networks is a "stateful" connection between service logic and the application server. Prior-art keywords include "mobile device," "session," "network," "devices," and "pan," and classifications include H04L65/1016 (IMS) and H04W88/06 (multi-mode terminals), consistent with discovery of associated devices.

What the excerpt does not establish: It does not supply the claims, full description, or detailed embodiments; the definitions section is explicitly truncated ("Excerpt only"). It therefore does not establish the specific claimed methods, the exact discovery mechanisms, or how "PAN" devices are used. It also does not establish litigation, ownership transfers, validity, or prior art, and the dates and assignee are presented as unverified assumptions.

All PTAB activity →AIA trial proceedings (IPR / PGR / CBM) filed at the USPTO Patent Trial and Appeal Board against this patent. Sourced from the USPTO Open Data Portal and refreshed every six hours; each proceeding number deep-links to the PTAB E2E docket.
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.
