Patent Overview — US12207437B2
Title: Electronic display with cooling
Patent number: US12207437B2 | Application: US18/243,407 (filed 2023-09-07) | Publication: 2025-01-21 | Granted: 2025-01-21 | Status: Active | Anticipated expiration: 2028-09-19
Assignee: Manufacturing Resources International Inc (original and current). Inventors: William Dunn, Tim Hubbard.
Priority: Earliest listed prior-art date 2008-03-03; priority claimed from multiple 2008–2009 US applications (e.g., US12/234,307, US12/234,360, US12/235,200, US12/237,365, US12/411,925, US12/556,029, US12/556,209, US12/620,330). The excerpts also reference application Ser. No. 12/641,468 as a continuation-in-part of several of these.
Purpose: The described embodiments "generally relate to cooling systems and in particular to cooling systems for electronic displays." The text notes that past conductive/convective systems tried to remove heat through display sidewalls, relying "primarily on fans for moving internal air (or ingested ambient air) within the housing past the components to be cooled and out of the display," with power supplies typically being the components at issue and heated air moved "into convectively thermal communication with fins."
Plain-language scope: Exemplary embodiments "may comprise two separate flow paths for gas through an electronic display," where "a first flow path may be a closed loop and a second flow path may be an open loop." The closed-loop path "travels acr[oss]" the display per the excerpted text. Prior-art keywords listed include "airflow pathway," "electronic display," "housing," "display assembly," and "electronic." Classifications include H05K7/20 (cooling/ventilating), G02F1/133385 (liquid-crystal cooling with fans), H05K7/20954 (cooling for display panels), and F28D9/00 (plate-like heat-exchange assemblies).
What the excerpt does not establish: The supplied text is explicitly excerpted and omits the claims, full description, drawings, and most of the specification. It therefore does not establish the actual claim scope, the complete closed-loop airflow routing, specific component arrangements, or the full priority chain. The "Active" status, expiration date, and assignee listing are stated on the source as assumptions, not legal conclusions. No litigation, ownership-transfer, validity, or prior-art analysis is made here.

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.
