Patent Overview — US 10085291 B2
Title: "Associated device discovery in IMS networks"
Patent number / application: US 10085291 B2; application US 15/210,263; publication US 20160323928 A1.
Assignee: Aylus Networks Inc (current and original assignee, per the listing).
Inventors: Shamim A. Naqvi, Prasad S. Dorbala, Ellis L. Wong, Mahesh N. Ganmukhi.
Dates: Priority date 2005-06-24 (claimed from US 11/166,407) with a further priority claim from US 11/282,924 (2005-11-18). Filing date 2016-07-14; publication date 2018-09-25 (grant). Listed legal status: Expired – Lifetime, adjusted expiration 2025-07-02.
Purpose and plain-language scope: The supplied text describes the invention as generally relating to IP Multimedia Subsystem (IMS) networks and, more specifically, to IMS users who use "perhaps multiple" discovered user endpoint devices. The background explains how mobile handsets connect through a Radio Access Network (RAN), Base Transceiver Stations, Base Station Controllers, Mobile Switching Centers and the PLMN/PSTN, and how voice traffic uses the circuit-switched paradigm (TDM, SS7 signaling) while IP data service is offered via an overlay packet network using a Packet Control Function. It also notes the evolution of legacy switching into a control component (soft switch) using MGCP and media gateway (MGW) components supporting both packet and other traffic. Classification entries tie the patent to IMS architecture (H04L65/1016), connection setup/multiple wireless links (H04W76/10, H04W76/15), short-range/device-to-device services (H04W4/80), session management (H04L67/14) and terminal devices adapted for multiple networks (H04W88/06).

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.
