Patent Overview — US11563621B2
Title: Cluster computing
Assignee: Advanced Cluster Systems Inc (original and current assignee, per the supplied text).
Key dates: Priority date 2006-06-13; filing date 2021-07-13 (application US17/374,864); publication date 2023-01-24; status Active, with an adjusted expiration listed as 2027-05-04.
Purpose: The patent addresses adding cluster computing functionality to computer programs. It notes that many applications are not designed to benefit from clusters, and some run on only a single node—for example, because they use a "kernel" (an interpreter managing hardware resources and communications) built to communicate with a single node. Mathematica® from Wolfram Research, Inc. is given as an example of such a single-node kernel. The disclosed approach adapts a software module designed to run on a single node to support cluster computing, even where the module was not designed to do so, and can provide parallelization even when no access to the program's source code is available.
Plain-language scope: In one embodiment, a cluster includes first, second, and third processors, each with a kernel that translates commands into code for its processor, plus a cluster node module per processor. The first cluster node module receives commands from a user interface, sends commands to the first kernel, and communicates with the other cluster node modules; it also comprises a data structure storing messages originating from the second and third cluster node modules. Another embodiment includes a user interface and a single-node kernel, with a cluster node module that communicates with that kernel and other cluster node modules, accepts instructions from the user interface, and appears as a single-node kernel to the user interface. The module may include a toolkit with library calls implementing at least a portion of MPI calls, or high-level cluster computing commands; MPI calls can be added within an interactive environment such as the Mathematica Front End.
What the excerpt does not establish: It does not provide the full claims, complete specification, drawings, or a complete list of cited prior art; it also does not establish legal conclusions about scope or coverage.

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.
