Purpose and plain-language scope (per the supplied excerpt):
The excerpt identifies the invention as a radio receiver and lists recurring concepts: signal(s), intermodulation, a signal or band "of interest," sampling, filtration, adaptive and blocking effects, phase shift, search algorithm, delay, amplification, quantization, and mitigation. In plain terms, the disclosed receiver appears directed to processing received signals to mitigate intermodulation interference affecting a band of interest—drawing on sampling, filtering, and adaptive/blocking techniques, with a search algorithm and phase/delay adjustments. The excerpt indicates the abstract and claims concern methods, with method claims and abstract referencing interception-related effects.
Classification-style subject matter noted: sampling (methods), intermodulation effects, adaptive and blocking effects, phase shift, search algorithms, surface acoustic wave methods, quantization.

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.
