Purpose and scope (plain language, per the supplied text):
The patent concerns decoding digital video/images using prediction. Classification entries describe methods for compressing or decompressing digital video signals using adaptive coding, including selection of coding or prediction mode, selection of a reference unit for prediction within a chosen mode (e.g., adaptive choice of position and number of pixels used for prediction), spatial predictive coding modes, subdivision of pictures into coding blocks, and motion inside a coding unit. Prior-art keywords listed are: block, prediction, image data, image, data.
In essence, as far as the supplied excerpt shows, the disclosed subject matter relates to predicting blocks of image data during decoding, selecting prediction modes and reference units, and handling adaptively coded video signals.

What the excerpt does not establish:
The supplied text contains no claims, no detailed description, no drawings content, and no specific prior-art references. It therefore does not establish the precise claimed scope, the number or wording of claims, the specific prediction/decoding steps, embodiments, or the identity of cited prior art. The excerpt also notes that listed assignees and legal status are assumptions/not legal conclusions and may be inaccurate; this overview repeats them without verification. No litigation, ownership-transfer, validity, or prior-art analysis is provided here.

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.
