Legal status: Expired – Fee Related; adjusted expiration 2025-07-23. The source notes legal status is an assumption, not a legal conclusion.
Purpose (per the supplied text): 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, BSC, MSC, GMSC, SS7) to overlay packet data (PCF) and 2.5G/3G multimedia, where the handset's IP context is maintained while powered on and connected—unlike traditional telephony, where connection state exists only during a call. It also notes the service logic–application server connection is "stateful" and must be maintained for the duration.
Plain-language scope (from the excerpt): The patent concerns discovering user endpoint devices associated with an IMS user, in a setting where a subscriber may employ more than one device. The excerpt characterizes IMS as supporting both voice and data services and describes the stateful nature of application-server connections.
Classifications (selected, per source): H04L65/1016 (IMS); H04W76/15 (multiple wireless link connections); H04M7/123 (packet-switched IMS-type network interconnection); H04W4/80 (short-range services); H04W88/06 (multi-mode terminals).

What the excerpt does not establish: It provides no claims, no detailed description of discovery mechanisms, no figures, and no named prior-art references. It does not establish claim scope, validity, inventorship disputes, or ownership transfers; the excerpt is partial, so omitted text may qualify the above.

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.
