Patent Overview — US10848398B2
Title: Method, apparatus, and system for optimizing performance of a communication unit by a remote server
Assignee/Current Assignee (as listed): Adaptive Spectrum and Signal Alignment Inc; original assignee Assia Spe LLC. Inventor: Wonjong Rhee.
Key dates: Priority/filing date 2011-11-10; publication of US20140304408A1 on 2014-10-09; granted and published as US10848398B2 on 2020-11-24; anticipated expiration 2031-11-10. Application number US14/356,581. Legal status listed as Active.
Purpose: The patent addresses the problem that conventional adaptation algorithms (e.g., rate adaptation in WiFi) are static—built into firmware with rules and thresholds fixed by the system designer. Because the designer's assumptions may not match actual operating environments, the communication system may perform poorly. The invention moves optimization to a remote server that can generate policies based on collected data.
Plain-language scope (from the excerpt): The disclosed method for optimizing performance of one or more communication units by a remote server comprises: (1) collecting data from the communication units; (2) generating a policy for each unit based on the collected data; and (3) sending the policy to each unit, where the policy comprises conditions for operation of the units, and the units implement the policy according to time-varying data. The excerpt also describes a system including a machine-readable storage medium with instructions causing a remote-server processor to perform the method, and a communication system comprising a WiFi Access Point or a DSLAM. Figures describe a prior-art communication system, WiFi and DSL optimization systems, server-side and communication-system-side methods, and a processor-based system. Classifications include H04L43/04 and H04L1/0019.

What the excerpt does not establish: It omits the full claims, detailed written description, and any specific policy-generation techniques. It provides no information on validity, enforceability, prior-art analysis, or the merits of any litigation; and it does not establish the accuracy of assignee listings or legal-status assumptions, which the source itself labels as assumptions, not legal conclusions.

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
