Purpose and plain-language scope. According to the supplied classification data, the disclosure concerns light guides — optical elements that carry and distribute light — specifically "planar or of plate-like form" guides for lighting devices or systems. Within that structure, the classifications identify: means for improving coupling of light into the guide (including shaping a portion of the guide, e.g. collimating, focusing or diverging surfaces, and forming holes or recesses to house at least part of a light source); and means for improving coupling of light out of the guide, such as 2-D arrangements of prisms, protrusions, indentations or roughened surfaces, and linear grooves extending over the full length or width of the guide. The listed prior-art keywords — light, assembly, film, deformities, sheet — are consistent with a panel that extracts light via surface deformities in a film or sheet. The excerpt also lists classifications for illuminated signs/luminous advertising (G09F13/00) and for refractors for light sources including photoluminescent material (F21V5/10), indicating contemplated signage and phosphor-related uses.
Not established by this excerpt. The supplied text contains no claims, no abstract, no detailed description, and no drawings/figures. It therefore does not establish the specific claimed combination, claim scope or limitations, the number of claims, any priority chain beyond the single claimed reference, any embodiments, or the meaning of "deformities" as used in the specification. Dates and statuses are as listed and are expressly assumptions, not 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.
Derivative works
Defensive disclosure: derivative variations of each claim designed to render future incremental improvements obvious or non-novel.
