Patent Overview — US 10721836 B2
Title: Electronic Display with Cooling
Patent number: US 10721836 B2 (application US 16/708,260; publication US 20200154597 A1)
Inventors: William Dunn; Tim Hubbard
Assignee: Manufacturing Resources International Inc. (original assignee and current assignee as listed)
Key dates: Priority date listed as 2008-03-03; filing date 2019-12-09; granted/publication date 2020-07-21; anticipated expiration 2028-09-19. Legal status shown as Active. The patent claims priority from a chain of earlier applications (including US 12/234,307, US 12/234,360, US 12/235,200, US 12/237,365, US 12/411,925, US 12/556,209, US 12/556,029, US 12/620,330, and US 12/641,468), some through provisional filings such as 61/033,064 (2008-03-03).
Purpose: The text states the described exemplary embodiments relate to cooling systems, and in particular to cooling systems for electronic displays. It explains that conductive and convective heat transfer systems for electronic displays generally attempt to remove heat from electronic components through the display sidewalls, that past systems relied primarily on fans to move internal or ingested ambient air past components to be cooled and out of the display, and that such components are typically power supplies.
Plain-language scope (from the supplied text): The disclosed subject matter concerns removing heat from electronic displays, using the enclosure and heat-exchange approaches to manage heat from heat-generating components such as power supplies. Classifications listed include H05K7/20 (cooling, ventilating, or heating of electric apparatus), H05K7/202 (air circulating in a closed loop within an enclosure wherein heat is removed through heat-exchangers), G02F1/133385 (cooling of liquid crystal cells with cooling means, e.g. fans), and H05K7/20954 (cooling for display panels). The prior-art keywords listed are: electronic image, image assembly, enclosure, mounting space, heat exchanger.

What this excerpt does not establish: It does not provide the actual claim language, the full specification, the drawings, or the detailed description. It therefore does not establish the precise metes and bounds of the claimed invention, the specific heat-exchange structures claimed, or the full technical disclosure. It also does not establish the accuracy of the listed legal status, priority dates, or assignee information, which the source itself describes as assumptions rather than 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
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.
