Patent Overview — US 9,282,676 B1
Title: Suspended electronic display and cooling assembly
Assignee: Manufacturing Resources International Inc. (original and current assignee as listed)
Inventor: Marcos Diaz
Key dates: Filing/priority date 2014-11-25; granted and published 2016-03-08; listed as active with an adjusted expiration of 2034-11-26.
Purpose: The assembly addresses cooling of electronic displays used outdoors or in hot environments, including heat from solar loading. A stated problem is that drawing ambient air into all portions of a display can introduce dust and contaminants into sensitive areas, causing premature failures.
Plain-language scope (from the supplied text): The assembly provides two separate fluid (air) flow paths through the display. A first path is a closed loop circulating through a sealed electronics compartment defined by a back pan, a perimeter wall, and a rear cover; it may circulate around and through partitions inside that compartment. A second path is an open loop defined by a channel between the back pan and the electronic display, drawing ambient gas in and exhausting it out the display housing. Both paths may contain fans. The assembly also includes passageways accommodating elongate members extending through the housing; these passageways sit outside the sealed electronics compartment and contain at least one clamp each, the clamps accommodating the elongate members so the assembly can be suspended from a support such as a frame. Figures 1–14 depict front/rear perspective and planar views, cross-sections, and detail views of the assembly and its flow paths.
Classifications include H05K7/20 (cooling, ventilating, heating), H05K7/20136 (forced ventilation, e.g. fans), H05K7/20954 (cooling for display panels), and F16M13/027 (ceiling supports).

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.
