US7574553B2 — Concise Patent Overview
Title: Digital component power savings in a host device and method
Patent number / application: US7574553B2, Appl. No. US11/454,493
Dates: Priority and filing date 2006-06-16; publication of US20070294464A1 on 2007-12-20; grant/publication 2009-08-11. Google Patents lists an adjusted expiration of 2027-09-14 (legal status is an assumption, not a legal conclusion).
Assignee: The "Current Assignee" listed is E2e Systems LLC, with Cornice Inc also listed; the original assignee is shown only as "Individual." The record shows assignment entries to Cornice, Inc. (2006-06-16), Hercules Technology Growth Capital, Inc. and Benhov GmbH, LLC (2007), and later to Intellectual Ventures Assets 207 LLC (2026-04-08) and E2e Systems LLC (2026-05-31).
Purpose (per the excerpt): To reduce power consumption of a host digital device by having a component that interfaces with the host monitor the interface itself, rather than relying on host signaling or a poorly tuned drive-side timer to power down a hard disk drive.
Plain-language scope (as described in the excerpt's definitions): A first digital component (embodied as a hard disk drive) shares an interface with other components and with a host that issues commands, some addressed to the first component. During idle time between commands, a control or monitoring arrangement watches the interface for commands directed to that component, drawing only a leakage current (in one embodiment, under 1 milliamp); the component may enter a "coma mode" limited to leakage current. On detecting a relevant issued command, a wake-up signal is generated and an operating arrangement works with the host to execute the command in a normal operational mode. The excerpt names figures 1–6, including flow-diagram FIG. 4.

What the excerpt does not establish: The full text of the claims, the complete description, the named prior-art references, and the contents of FIGS. 1–6 are not reproduced; the classifications (e.g., G06F1/3203, G06F1/3221) are listed but not explained. The excerpt alone does not establish claim scope, validity, or the details behind any ownership transaction.

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.
