Purpose and plain-language scope
The patent concerns light emitting panel assemblies. The listed prior-art keywords are "light," "emitting panel," "light emitting," "panel member," and "major surface," indicating a panel member with a major surface through which light is emitted. Classifications further indicate a planar/plate-like light guide with means for coupling light in from a source and redirecting means on the light guide's surface. Keyword-frequency data in the excerpt lists, among terms appearing in the claims/abstract, "liquid crystal," "optical film," and "optical effect," and among description terms "transition," "film," "distribution," "coating," "adhesive," "colorant," and "ink." Google Patents also lists litigation entries (Texas Eastern District Court cases 2:14-cv-00142, -00145 and -00146) and assignments dated 2013.
What the excerpt does not establish
The supplied text contains no claim language, no written description, and no abstract, so it does not establish the actual claimed scope, the specific embodiments, the intended applications, or the meaning of any term beyond the keyword and classification data above. It also does not establish the accuracy or legal effect of the listed priority date, status, assignee, or litigation records — the source itself labels status, priority, and assignee data as assumptions or non-conclusions. Nothing here is evidence of validity, infringement, ownership, or prior art. No further detail should be inferred beyond the excerpt.

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.
