Patent Overview — US 9,155,026 B2
Title: Systems for facilitating wireless communication and related methods
Assignee: HTC Corp (original assignee also HTC Corp)
Inventor: Huaiyuan Wang
Key dates: Priority date 2012-01-10; filing date 2012-02-14; publication date 2015-10-06 (application US13/372,701; US20130178160A1 published 2013-07-11). Legal status listed as Expired – Fee Related, with an adjusted expiration of 2032-06-21 (Google Patents notes legal status is an assumption, not a legal conclusion).
Purpose: The disclosure generally relates to Wi-Fi communication. Conventional Wi-Fi passive scanning is energy-expensive: the patent states that scanning all 35 channels (12 in 2.4 GHz, 23 in 5 GHz) at up to a 100 ms beacon interval yields about 3500 ms of scanning per 5-minute cycle — a 1.167% duty cycle — and, at 70 mA receiver draw, over 0.8 mAh per scan cycle. The disclosed approach instead uses Bluetooth Low Energy (BLE) to carry Wi-Fi information, which "uses less energy than may be required for such scanning using standard Wi-Fi scanning procedures."
Plain-language scope: A Bluetooth transmitter is collocated with a Wi-Fi-capable device (e.g., an access point or peer device such as Wi-Fi speakers, dongles, or printers) and broadcasts BLE Advertisement packets carrying Wi-Fi information — potentially SSID, BSSID, operating band, channel number, and other predefined information elements. An electronic device (e.g., smartphone, tablet) monitors BLE advertising channels via a BLE receiver/Wi-Fi monitoring system. On receiving the Wi-Fi information (e.g., ADV_IND or ADV_NONCONN_IND packets), it may optionally open a BLE data connection for further information exchange, then uses the received information to initiate Wi-Fi authentication and association, or peer-to-peer connection, with the Wi-Fi-capable device.
What the excerpt does not establish: The full claim set and detailed description are omitted, so precise claim scope cannot be confirmed. The excerpt also does not establish other family members' substantive content, or the accuracy of the listed legal status.

Proceedings on file (0)
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.
