Patent Overview — US10194168B2
Title: Method for inducing prediction motion vector and apparatuses using same
Patent number / application: US10194168B2; application US15/244,579 (publication US20160366436A1).
Assignee(s): Electronics and Telecommunications Research Institute (ETRI) and University Industry Cooperation Foundation of Korea Aerospace University.
Key dates: Priority date 2011-09-16; filing date 2016-08-23; publication date 2019-01-29; status listed Active, with adjusted expiration 2033-03-05. Legal status and dates are expressly noted in the source as assumptions, not legal conclusions.

Purpose (per the source): The invention addresses video encoding/decoding, specifically inducing a prediction motion vector. Stated objects are to provide a method of configuring a candidate prediction motion vector list for increasing video encoding/decoding efficiency, and an apparatus performing that method.
Plain-language scope (from the supplied excerpt): The described method configures a candidate prediction motion vector list by (1) determining information regarding a plurality of spatial candidate prediction motion vectors from an adjacent prediction block of a prediction target block, and (2) determining information regarding a temporal candidate prediction motion vector based on the information regarding the plurality of spatial candidate prediction motion vectors. The spatial information may include spatial candidate prediction motion vector availability information (whether a spatial candidate prediction motion vector is induced) and/or the spatial candidate prediction motion vector itself; the temporal information may similarly include temporal availability information and/or the temporal candidate prediction motion vector. The excerpt states the spatial-determining step "may include the step" but the text is truncated at that point.
Classifications include: H04N19/52 (predictive encoding of motion vectors), H04N19/513, H04N19/176, H04N19/105, among others.

What the excerpt does not establish: It does not provide the full claims, the complete specification, detailed embodiments, the remainder of the spatial-determining step, any prior-art references or comparisons, claim validity, or the actual scope of enforceable claims. It also notes litigation-related metadata (a Darts-ip link) without substantiating it. No legal conclusions should be drawn from this overview.

Proceedings on file (0)
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.
