Patent Overview — US 9,210,603 B2
Title: "Technique for performing physical layer measurements"
Patent number: US 9,210,603 B2. Application number: US 14/605,862. Publication: US 2015/0139019 A1 (published 2015-05-21). Grant date: 2015-12-08. Filing date: 2015-01-26. Priority date: 2009-11-30. Anticipated expiration: 2030-11-25. Legal status: Expired – Fee Related (as listed).
Inventors: Bengt Lindoff, Robert Baldemair, Lars Sundström. Original assignee: Optis Wireless Technology LLC. Current assignees listed: Optis Wireless Technology LLC and Cluster LLC. The source also records an assignment to Telefonaktiebolaget LM Ericsson (Publ) dated 2015-08-19, followed by assignments to Cluster LLC and then Optis Wireless Technology, LLC, all on the same date.
Purpose and plain-language scope: The disclosure concerns physical layer measurements in evolved Universal Terrestrial Radio Access Network (E-UTRAN)/LTE-Advanced systems that aggregate multiple frequency resources (component carriers), where a selected resource serves as the anchor or primary component carrier. Because receiving control signaling across multiple frequency resources is described as non-optimal for power consumption, the patent addresses the need for a technique that manages physical layer measurements so that resultant transients do not disturb communication, or potential communication, over those frequency resources. As described in the supplied excerpt, a mobile terminal determines that it is to perform a physical layer measurement with regard to a first frequency resource, and determines whether there is data to be communicated over one or more second frequency resource(s) within a time period. The excerpt is cut off mid-sentence at that point.

What the excerpt does not establish: It does not supply the full claims, the complete algorithm or its conditions, detailed embodiments, or figures. It also does not establish the legal status, ownership, or validity as findings of this overview; the listed classifications (e.g., H04W24/08, H04W24/10, H04W36/0085) are given as classifications only.

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.
