Purpose. The patent addresses cooling systems for electronic displays. The excerpt states that prior conductive and convective heat-transfer systems generally tried to remove heat through display sidewalls, and that past systems relied primarily on fans moving internal or ingested ambient air past components (typically power supplies) and out of the housing, with heated air moved into convective thermal communication with fins.
Plain-language scope (per the excerpt). Exemplary embodiments may comprise two separate gas flow paths through the display: a first, closed-loop flow path and a second, open-loop flow path. The closed loop travels across the front surface of the image assembly, continues to the rear where it may enter a heat exchanger, and returns to the front surface. The open loop may draw ambient gas (e.g., ambient air) through the rear of the display — sometimes through a heat exchanger, behind an image assembly, or both — and exhaust it out of the display housing. A heat exchanger may transfer heat from the circulating gas to the ambient gas. Ambient gas may also be forced behind the image assembly (sometimes a backlight) to cool the image assembly and/or backlight.
Internal references (excerpt). The text identifies a chain of applications incorporated by reference, including Ser. Nos. 12/641,468, 12/237,365 (U.S. Pat. No. 8,879,042), 12/235,200, 12/620,330 (U.S. Pat. No. 8,274,622), and 12/556,209 (U.S. Pat. No. 8,379,182), among others.
What the excerpt does not establish. The supplied text contains no claim language and no prior-art references. It therefore does not establish claim scope, validity, patentability, or the accuracy of the listed dates, priority, status, or assignee information. The excerpt is also expressly noted as possibly incomplete.

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.
