Patent Overview — US9131336B2
Title: System and method for facilitating short-range wireless communications between a mobile wireless device and an auxiliary system.
Patent number / application: US9131336B2, application US14/334,900. Inventors: Ronald Scotte Zinn and Sean Elliott Wilson. Original assignee: BlackBerry Ltd (Research In Motion Limited); current assignee listed as Malikie Innovations Ltd.
Key dates: Priority date 2004-05-10; filing date 2014-07-18; publication of US20140370813A1 on 2014-12-18; grant/publication as US9131336B2 on 2015-09-08; anticipated expiration 2024-05-10. Legal status: expired – lifetime.
Purpose: To increase interoperability between wireless devices (e.g., cellular telephones, data messaging devices) and other electronic systems, such as an automobile audio system, without interfering with stand-alone device functions and while keeping user input to a minimum. One motivating example is using a cellular telephone through an automobile's microphone and speakers for hands-free operation.
Plain-language scope: The patent describes a wireless device with a short-range transceiver that communicates with an auxiliary device. A signal module supplies a mode control signal, and a control module shifts the transceiver between a "power saver mode" and a "search mode." In search mode, the transceiver searches for the auxiliary device; in power saver mode, it does not search. The signal module may include a single-action user input, or a detector that senses when an auxiliary device is in close proximity (sending a first signal when proximate and a second when not). The control module moves the transceiver from power saver to search upon the first signal, and back upon the second. In one described variant, a proximate device indicator comprises a magnet and the detector detects the magnet. A corresponding method and wireless system are also described, along with figures including FIGS. 1–4c.
What the excerpt does not establish: It does not provide the full specification, complete claim set, prosecution history, or figures' details; the excerpt explicitly notes omitted text. It also does not establish litigation, validity, ownership-transfer details, or prior art.

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.
