Patent Overview — US6701431B2
Title: Method of generating a configuration for a configurable spread spectrum communication device
Patent number / application: US6701431B2; application US09/772,582, filed 2001-01-29; granted 2004-03-02. Priority date listed as 2000-01-28. Status listed as "Expired – Lifetime," adjusted expiration 2022-10-13.
Inventor(s): Ravi Subramanian and Christopher Woodthorpe.
Assignee information (as listed): Original assignee Infineon Technologies AG; current assignee entries Infineon Technologies AG and Morphics Technology Inc. The source notes that listed assignees may be inaccurate and that no legal analysis was performed.
Purpose: The patent addresses the problem that spread spectrum applications (e.g., fixed wireless, unlicensed FCC wireless, LAN, cordless telephony, personal base station, telemetry, mobile wireless) generally use unique and incompatible protocols, requiring distinct hardware, software, and methodologies — costly in design, testing, manufacturing, and infrastructure. The invention aims to configure a general-purpose spread spectrum device to perform a specific application, manage external control of that device, avoid working through the entire set of possible combinations and permutations of hardware sequencing and variable assignments, and verify/simulate operation of the externally controlled device.
Plain-language scope (per the excerpt): A method implemented on a computing device with a processor and computer-readable memory. Steps include: receiving input identifying a desired function and a desired operation within that function to be implemented by a configurable communication device; generating a signal flow path for the desired operation; mapping the desired operation onto a function-specific computing element (or set) with localized control within the configurable device; repeating these steps to satisfy multiple operations enabling the desired function; and configuring a configurable interconnect to enable the signal flow path and mapping across computing elements. A second embodiment is described as an electronic device with processor and coupled computer-readable memory containing instructions.
What the excerpt does not establish: The full text of the claims, the detailed description, and the drawing contents are omitted from the supplied excerpt. It therefore does not establish the precise claim scope, the complete list of referenced prior art, or the specific implementation details of the described embodiments. Only the definitions and summary passages quoted above are available.

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.
