Patent Overview: US9711127B2
Title: Multi-sensor signal optimization for speech communication
Patent number / application: US9711127B2 (application US13/621,432)
Inventors: Siew Kok Hui; Eng Sui Tan
Original assignee: Bitwave Pte Ltd
Key dates: Priority date 2011-09-19; filed 2012-09-17; published as US20130070935A1 on 2013-03-21; granted 2017-07-18. The listing shows a legal status of "Active" with an adjusted expiration of 2033-12-08, but the source expressly notes that legal status is an assumption and not a legal conclusion.
Purpose: The disclosure addresses speech communication, and in particular multi-sensor signal optimization for speech communication. It notes that headsets with microphones are used for entertainment, communication, and "hands free" voice-command control by people on the move (for example, cycling, motorcycling, boating, or driving), including in outdoor settings. The stated aim is to enhance speech-communication performance, for example in noisy environments, by computing noise information for microphones and an output of a spatial filter, and selecting a portion of that noise information, or an optimized combination of portions of it.
Plain-language scope (as described in the supplied excerpt): A system—such as a headset or helmet—includes a sensor component with acoustic sensors (for example, microphones, a bone-conduction microphone, an air-conduction microphone, or an omnidirectional sensor) that generate first and second sound information. An audio processing component (for example, a digital signal processor) generates filtered sound information using the first sound information, the second sound information, and a spatial filter (for example, a beamformer or adaptive beamformer). The audio processing component determines noise levels, such as signal-to-noise ratios, for the first sound information, the second sound information, and the filtered sound information, and generates output sound information based on selecting one of those noise levels or a weighted combination of them. A transceiver component can send the output sound information to a communication device.

What the excerpt does not establish: The supplied text is explicitly marked as an excerpt. It contains no claim language, complete specification, drawings, or listed prior-art references, so it cannot support a specific claim construction, confirmed claim scope, or conclusions about novelty or validity. It also does not document ownership changes or litigation, and per instruction those were not researched.

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.
