Purpose and plain-language scope (based on the supplied text):
The patent is directed to a framework supporting content delivery, and specifically to “adaptation services” within that framework. In plain terms, the disclosed subject matter concerns systems, methods, and/or apparatus for delivering content across a network in which the framework can adapt content delivery through one or more services. The listed “prior art keywords” in the supplied text (service, services, information, control, particular device) indicate the disclosure centers on service-based control and information handling for a device within the delivery framework. The text also notes a “First worldwide family litigation filed” link (Darts-ip), indicating litigation is associated with the family, though no case details are supplied.
What the excerpt does not establish:
The supplied source is largely a bibliographic/classification and procedural record. It does not include the claims, specification, drawings (images are present but not rendered as text), or detailed technical description. Therefore it does not establish the specific claimed subject matter, the precise operation of the “adaptation services,” claim scope, dependency, or any limitations. It also does not establish validity, patentability, enforceability, or legal status beyond the listed “Active” assumption. No conclusions about ownership transfers, litigation substance, or prior art should be drawn from this excerpt.

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.
