Purpose: The patent addresses a data gateway for updating user data from multiple data sources. The source describes problems in conventional server-farm gateways: transferring job requests from a failed server without loss, scaling to a growing user base when persistent storage holds jobs at differing processing stages, and inefficiency when a user's job requests are spread across servers so account data must be cached in multiple places.
Plain-language scope: The gateway includes a server farm of multiple servers, with both a persistent job table (centrally storing jobs to be processed) and a server table (centrally storing server activity statuses) residing outside the servers, plus a job engine using both tables. A virtual Internet Protocol load balancer dynamically maps jobs to servers according to user identifiers. A method includes receiving a job request, fetching due jobs from the persistent job table, sending them to a storage queue, rescheduling them in the persistent job table for future processing, dispatching a job to a job handler, and processing it according to data source type. The excerpt also mentions figures covering server farms, the job engine, timer-driven scheduling, a job dispatcher, and a hierarchical job-locking scheme.

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.
