Patent Overview: US 11770313 B2
Title: Method, apparatus, and system for optimizing performance of a communication unit by a remote server
Assignee: Adaptive Spectrum and Signal Alignment Inc (current); original assignee Assia Spe LLC. Inventor: Wonjong Rhee.
Key dates: Priority date 2011-11-10; filing date 2020-11-23; publication date 2023-09-26; anticipated expiration 2031-11-10. Status: Active.
Purpose: The patent addresses the problem that conventional adaptation algorithms (e.g., rate adaptation in WiFi) are static—implemented in firmware and governed by fixed designer assumptions that may not match real operating environments, causing poor performance. Embodiments described relate to optimizing performance of a communication unit by a remote server.
Plain-language scope: A remote server collects data from one or more communication units, generates a policy for each unit based on that data, and sends the policy to the units. The policy contains conditions for operation, and the units implement the policy according to time-varying data. On the device side, a communication unit sends data to the remote server, receives the policy, and executes it by implementing one of first and second algorithms based on the conditions and time-varying data. The described system may include a WiFi Access Point or a Digital Subscriber Line Access Multiplexer (DSLAM). The specification states embodiments are not limited to DSL or WiFi and apply to any communication system needing adaptation algorithms to cope with real-time variations in link channel, noise, interference, and other performance-affecting factors. The excerpt also mentions a machine-readable storage medium with executable instructions and a processor-based system.

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.
