Title: Devices and methods supporting content delivery with rendezvous services
Patent number / application: US 9,705,754 B2; Application US 13/715,747; pre-grant publication US 2014/0173047 A1.
Inventors: William Crowder, Andrew Swart, Christopher Newton, Lewis Robert Varney, Laurence R. Lipstone.
Assignee: Original assignee Level 3 Communications LLC; current assignee listed as Sandpiper CDN LLC (per the supplied text's assignment entries).
Key dates: Priority date 2012-12-13; filing date 2012-12-14; publication 2017-07-11; adjusted expiration 2034-02-09. Legal status listed as Active.
Purpose and plain-language scope (from the supplied text):
The patent relates to devices and methods that support content delivery using "rendezvous services." The recurring prior-art keywords in the supplied text — services, information, service, control, collector — indicate the disclosure concerns a framework of services for handling content-delivery information and control, with a collector component. In ordinary terms, the claimed subject matter appears directed to a system and method in which a content-delivery platform uses a rendezvous service to coordinate delivery-related information and control functions among components, rather than to a single delivery server acting alone.

What the supplied excerpt does not establish:
The excerpt contains only bibliographic, procedural, and timeline data plus keyword metadata. It does not reproduce the abstract, any claim language, the written description, or the drawings, so the precise scope of the claims, the exact operation of the "rendezvous services," and the technical details of the "collector" or control functions cannot be determined from this text. Nothing here establishes validity, enforceability, infringement, or the content of any prior-art reference. The excerpt also does not verify the accuracy of the listed legal status, expiration date, or assignee, which the source itself labels as assumptions or as based on data not analyzed. No litigation, ownership-transfer, or prior-art analysis is drawn from this excerpt.

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.
