Purpose (plain language, limited to the supplied text): The patent is titled a "global hosting system." The source excerpt supplies no abstract and no claim text; the only substantive signals are the title, the classification codes, and the "prior art keywords."
Scope as indicated by the supplied excerpt: The prior-art keywords listed are content, server, page, servers, and content provider, indicating subject matter directed to serving content pages from multiple servers on behalf of a content provider. The classifications point to: web retrieval and browsing optimisation including caching or content distillation (G06F16/957); organisation or management of web site content, e.g. publishing, maintaining pages or automatic linking (G06F16/958); DNS-based name-to-address mapping (H04L61/4511); IP address allocation (H04L61/5007); HTTP-based protocols (H04L67/02); replicated servers and server selection for load balancing (H04L67/1001, H04L67/1004), including selection based on server parameters such as workload (H04L67/1008), on network conditions (H04L67/101), and random or heuristic selection (H04L67/1019). These codes are the source's own mapping, not a restatement of claims.
What this excerpt does not establish: It contains no abstract, no claim language, no written description, and no drawings, so the actual claimed scope cannot be determined from it. It does not establish the inventors' specific technical contribution, embodiments, or limitations. Dates are expressly identified by the source as assumptions and not legal conclusions, and the legal status is likewise an assumption rather than a legal analysis. Related-family filings, continuations, and litigation entries appear in the source but are outside the permitted scope of this overview and are not assessed here.

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.
