Purpose (plain-language scope, per the excerpt):
The patent relates to video coding/decoding using predictive coding. Based on the classification data and prior-art keywords supplied, it concerns intra (spatial) prediction, where a current block is predicted from already-reconstructed neighboring pixels ("prediction," "block," "mode," "current block," "pixel"). The title indicates reconstructed blocks are generated using a filter applied in connection with an intra prediction mode. Classifications include selection of coding mode/prediction mode (H04N19/103, H04N19/11), selection of a reference unit for prediction (H04N19/105), spatial prediction (H04N19/593), and filters (H04N19/117), consistent with filtering predicted samples based on the intra mode.

What the excerpt does not establish:
The supplied text provides only bibliographic, classification, and keyword metadata; it omits the claims, detailed description, and drawings. Therefore it does not establish: the specific filter coefficients or filter types, which intra prediction modes trigger filtering, how the bitstream signals mode/filter information, the precise number or wording of claims, the scope of protection, or the embodiments disclosed. The excerpt's note that the "family has litigation" is a metadata field only; no litigation details, validity, ownership transfers, or prior-art analysis are addressed here per instruction.

All PTAB activity →AIA trial proceedings (IPR / PGR / CBM) filed at the USPTO Patent Trial and Appeal Board against this patent. Sourced from the USPTO Open Data Portal and refreshed every six hours; each proceeding number deep-links to the PTAB E2E docket.
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.
