Patent Overview — US 9100780 B2
Title: Method and apparatus for managing positioning assistance data
Patent number / application: US 9100780 B2; application US 13/783,015; pre-grant publication US 20140248899A1
Assignee: Qualcomm Incorporated (original assignee; assignment recorded 2013-04-04)
Inventors: Amir A. Emadzadeh; Sundar Raman
Key dates (as listed, stated as assumptions on the source page): priority date 2013-03-01; filing date 2013-03-01; publication date 2015-08-04; adjusted expiration 2033-05-01. Legal status: Expired – Fee Related. PCT/US2014/017535 (WO2014133878A1) also claims priority.
Purpose: Location based services (LBS) such as personal navigation, social networking, and content targeting rely on assistance data describing nodes (e.g., base stations) in areas defined as regions. The patent addresses managing that assistance data when a region's data is too large for a mobile device.
Plain-language scope (from the supplied definitions/abstract): In one aspect, a method obtains assistance data for a "master region" including a set of nodes; determines whether the total assistance-data size exceeds a mobile device operating capacity or the total node count exceeds an upper-bound number; and, if either condition is met, divides the master region into sub-regions according to one or more criteria. In another aspect, a mobile device identifies its master region and associated sub-region definitions (indicating the area each sub-region occupies), obtains a first estimated position, defines a projected area ("horizon tile") centered at that estimate, and obtains assistance data for at least one sub-region overlapping the projected area. Corresponding apparatus, mobile-device, and means-plus-function claims are described. Classifications include G01S5/0236 (assistance data, e.g., base station almanac), H04W4/029, and H04W64/00.

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.
