Patent Overview — US 7,558,283 B2
Title: Method, apparatus and computer program product providing quality of service support in a wireless communications system
Patent number / application: US 7,558,283 B2; Application No. US 11/071,492
Assignee (per source): Original assignee Nokia Inc; current assignee listed as Nokia Technologies Oy and Vringo Infrastructure Inc. (per the source's list; the source notes listed assignees may be inaccurate and that it performed no legal analysis.)
Key dates: Prior art date 2004-03-12; application filed 2005-03-02; publication date 2009-07-07. Legal status listed as expired – lifetime, with anticipated expiration 2025-03-02.
Purpose: The patent relates generally to Quality of Service (QoS) correlation between entities in a communication system, and more specifically to packet data mode handoff techniques in a radio network serving a mobile station, accommodating a mobile node's QoS during and after handoff. It also addresses conventional cdma2000-type QoS negotiation problems, where the Mobile Station (MS) cannot correlate higher-layer QoS signaling (RESV) with a newly established Service Instance when the Service Reference Identifier (SR_ID) is assigned only during auxiliary service instance setup, and where the Packet Data Serving Node (PDSN) cannot correlate an R-P update message with a later R-P setup request.
Plain-language scope (as described in the excerpt): The invention provides a method for correlating a service instance for an MS, a Radio Access Network (RAN), and a PDSN connection by exchanging identifiers between the entities involved. The method comprises receiving from a mobile station a 3GPP2-RSVP Resv message including a request for a plurality [text excerpt ends here]. The excerpt does not set out the full claim language, the remaining method steps, or the apparatus and computer program product aspects.
What the excerpt does not establish: It does not provide the complete claims or full specification, the full assignee chain or its accuracy, validity, enforceability, or prior-art comparison. It also does not establish the details of the asserted invention beyond the described correlation purpose.

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.
