Patent Overview — US 8,352,400 B2
Title: Adaptive pattern recognition based controller apparatus and method and human-factored interface therefore
Patent number / application: US8352400B2; Application US13/244,152; publication US20120017232A1.
Inventors: Steven M. Hoffberg; Linda I. Hoffberg-Borghesani.
Assignee: Listed as Individual (original assignee Individual; Google notes assignee listings may be inaccurate and that it performed no analysis or warranty).
Dates (as supplied): Priority date 1991-12-23 (priority claimed from US07/812,805); filing date 2011-09-23; publication date 2013-01-08; adjusted expiration 2012-01-02. Legal status: Expired – Fee Related.
Purpose: The supplied definitions state the invention "relates to the field of programmable sequencing devices, or, more particularly, the field of remote controls for consumer electronic devices," and "provides an enhanced interface for facilitating human input of a desired control sequence in a programmable device by employing specialized visual feedback." The text notes popular programmable products including VCRs, answering machines, microwave ovens, alarm clocks, thermostats, cameras, home security systems, lighting systems, and automobiles. It describes problems such as remote controls with many buttons causing user confusion, under-utilization of buttons, and greater "search time"; the stated aim is to let all segments of the population effectively interface with programmable devices and let a manufacturer produce a single device without regard to a user's ability to learn programming steps.
Plain-language scope (from the source text): An adaptive, pattern-recognition-based controller with a human-factored interface that gives visual feedback to help a person enter a desired control sequence, applied to programmable consumer devices. Classifications listed include fuzzy logic, machine learning, knowledge-based/inference models, adaptive control, and home automation.

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.
