US7616601B2 — Network Resource Manager in a Mobile Telecommunication System
Overview (from supplied source text only)
Title: Network resource manager in a mobile telecommunication system.
Identifiers: US7616601B2; application US10/250,702; earlier publication US20040082338A1.
Dates: Priority date 2001-01-16; filing date 2001-12-20; granted/publication of US7616601B2 on 2009-11-10. Legal status shown as "Expired – Lifetime," with an adjusted expiration of 2023-07-16.
Inventors / Assignee: Joakim Norrgard, Anders Larsson, and Olov Schelen. Current assignee listed as NetSocket Inc; original assignee NetSocket Inc. The source text also lists multiple later reassignments (e.g., OPERAX AB, NYA OPERAX AB, NETSOCKET, INC., ALLIACENSE LIMITED LLC, LIT-US CHISUM 22-A LLC) and a security agreement with Comerica Bank. Per instruction, these are noted only as they appear and are not analyzed here.
Purpose and plain-language scope: Based on the title, classifications, and prior-art keywords, the patent concerns managing network resources in a mobile telecommunication system. Classifications place it in wireless network resource management and QoS negotiation (H04W28/00, H04W28/16, H04W28/24), and in data-network traffic control, admission control, and resource allocation (H04L47/*), including centralized and distributed allocation (bandwidth brokers), reservation during connection setup, dynamic reallocation after handoff, and QoS mapping between different networks. The recurring prior-art keyword "NRM" (network resource manager) and "RAN" (radio access network) indicate the described subject matter involves an NRM interacting with a radio access network to allocate or reserve resources.
What this excerpt does not establish: It does not include the abstract, claims, detailed description, drawings, or specific prior-art references, so the precise claimed scope, embodiments, and technical mechanisms cannot be stated. It also does not establish litigation outcomes, ownership validity, patentability, or the accuracy of the listed legal status, which the source itself describes as an assumption and not a legal conclusion.

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.
