Purpose: The invention addresses the prior-art problem that operating parameters for automatically and dynamically adjusting a hardware component — and the required reference value — were not provided, aiming to improve performance and enable more effective protection. It is described as particularly for controlling required voltage and core frequency according to load current.
Plain-language scope: The operation monitor device controls output voltage to a hardware component operating within a system. It comprises a PWM module, a monitoring unit, and a controller. The PWM module generates output voltage/current according to a reference voltage and detects load-current variation from the component's operation, producing a voltage variation detected by the monitoring unit, which outputs a detecting result to the system. The system feeds back a monitor signal; the monitoring unit generates a modulating signal in response, and the controller generates a new reference voltage, which the PWM module uses to modulate output voltage. The controller may include a signal converter (with a conversion table) and a reference voltage generator (with a parameter table). Communication may use an I2C bus; the monitoring unit may be a hardware monitor and may control a heatsink (e.g., a fan). The hardware component may be a processor (GPU/CPU) or memory. The PWM module may include an integrated circuit, a power switch (e.g., MOSFET), an output circuit, and two impedance components.

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.
