Purpose and plain-language scope
The patent is directed to optimizing signals from multiple sensors for speech communication. The supplied text's definitions describe a first sensor as a first microphone positioned at a location corresponding to a first speaker, and a second sensor as a second microphone positioned at a location corresponding to a second speaker. Each sensor can be embedded in a speaker housing—for example, an earbud—proximate to a user's eardrum. The definitions also describe a bone conduction microphone positioned adjacent to an air conduction microphone within a structure (e.g., soft rubber material enclosing air), with a foam material between the structure and the microphones to reduce mechanical vibration.
The figures referenced in the excerpt include a zone created in the center of an array associated with a digital beamformer, a bicycle helmet including a dual acoustic sensor device, and a headset including dual acoustic sensors. Classifications assigned to the patent include noise filtering, frequency-domain processing, microphone arrays/beamforming, and combining signals of two or more microphones, consistent with a multi-sensor noise-reduction and beamforming approach to speech pickup.
Because the source text is an excerpt, the full claim set is not reproduced here. The excerpt's definitions describe structural arrangements (microphone placement, earbud housings, bone/air conduction microphone pairing, foam isolation) rather than reciting complete claim language; a precise statement of claimed scope cannot be made from this text alone.
What the excerpt does not establish
The supplied text does not provide the full claims or detailed description. It does not establish the specific signal-processing steps or algorithms beyond the classification hints and figure captions. It does not provide the identity or content of cited prior art, the prosecution history, or the basis for the 2011 priority date beyond the listed entry. It does not establish current ownership or validity beyond the listed assignee entries.

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.
