Abstract: The patent describes a method for operating a heterogeneous computing system. This system includes computation nodes and booster nodes that process a computation task broken down into sub-tasks. Initially, these sub-tasks are assigned and processed in a "first distribution." Subsequently, the system uses information gathered from this initial processing to generate a "further distribution" of sub-tasks, aiming to optimize processing in a subsequent computing iteration.

Independent Claims Overview:

Independent Claim 1 (Method Claim):
This claim details a method for dynamically managing sub-tasks within a heterogeneous computing system. In essence, it involves:

1. Initial Processing: Taking a computation task with multiple sub-tasks and, in a first computing round, assigning and processing these sub-tasks across a portion of the available computation nodes and booster nodes.
2. Information Gathering: Collecting data about how these sub-tasks were processed by the nodes.
3. Dynamic Re-distribution: Using the collected information to create a new, refined distribution of sub-tasks for processing in a future computing round. The goal is to improve how tasks are handled in subsequent iterations.

Independent Claim 9 (System Claim):
This claim outlines the components of a heterogeneous computing system designed to perform the method described in Claim 1. Key components include:

1. Computing Hardware: A collection of computation nodes and booster nodes designed to execute tasks comprising multiple sub-tasks.
2. Connectivity: A communication interface that connects all computation nodes to each other and to the booster nodes.
3. Resource Manager: A component responsible for initially assigning portions of the booster nodes and computation nodes to handle tasks in a first computing round.
4. Application Manager: A component configured to receive performance data from "daemons" (background processes) operating within the computation and booster nodes. This manager then uses this information to update and improve the distribution of sub-tasks between the computation nodes and booster nodes for subsequent computing rounds.

```**US Patent 11537442: Application Runtime Determined Dynamical Allocation of Heterogeneous Compute Resources**

**Title:** Application runtime determined dynamical allocation of heterogeneous compute resources
**Current Assignee:** Partec AG
**Inventors:** Thomas Lippert, Bernhard Frohwitter
**Filing Date:** January 23, 2019
**Issue Date:** December 27, 2022
**Abstract:** The patent describes a method for operating a heterogeneous computing system that includes both computation nodes and booster nodes. When a computation task, composed of multiple sub-tasks, is processed, the system initially assigns these sub-tasks in a first distribution. Information gathered from this initial processing is then used to generate a refined "further distribution" of sub-tasks among the nodes for improved processing in subsequent computing iterations.

**Plain-Language Overview of Independent Claims:**

*   **Independent Claim 1 (Method):** This claim outlines a method for efficiently handling complex computational tasks on a system with different types of processing units (computation nodes and booster nodes). It involves an initial step where sub-tasks are distributed and processed. Crucially, the system then collects data about how well those sub-tasks were processed. Based on this feedback, it generates an improved plan for distributing the sub-tasks for any subsequent rounds of computation, aiming to optimize performance.

*   **Independent Claim 9 (System):** This claim describes the actual hardware and software components of such a heterogeneous computing system. Key elements include: a collection of standard computation nodes and specialized booster nodes for executing tasks broken into smaller sub-tasks; a communication network linking these nodes; a "resource manager" responsible for the initial assignment of nodes to tasks; and an "application manager." The application manager is designed to receive real-time performance data from monitoring software ("daemons") running on the nodes. It then uses this information to dynamically adjust and improve how sub-tasks are distributed between the computation and booster nodes for all subsequent processing iterations.

**CAFC 2026 Dockets:**
As of April 26, 2026, a search of the CAFC 2026 dockets for patent number 11537442 did not yield any specific litigation information within that court. However, other litigation related to this patent has been noted, including PTAB case IPR2025-00318, which has been filed and instituted with Microsoft Corporation as the petitioner, and a US case filed in the Texas Eastern District Court (case 2:24-cv-00433).

Proceedings overview

There is one AIA trial proceeding on file for US patent 11537442. This proceeding, IPR2025-00318, was terminated due to settlement. This means the patent has not undergone a full PTAB trial resulting in claims being invalidated or sustained. For a defendant, this indicates that the patent has not been challenged to a final decision at the PTAB, leaving all claims untested by a final written decision.

IPR2025-00318 — Microsoft Corporation v. ParTec AG

• Type: Inter Partes Review
• Filed: 2024-12-20
• Status: Terminated-Settled – The proceeding was concluded due to a settlement between the parties.
• Judge panel: Information not available in public snippets.
• Petition grounds: Details regarding the specific claims challenged, prior art asserted, and statutory bases (§ 102 / § 103 / § 112) for the petition are not publicly available in the provided snippets. This information would typically be found in the petition itself on the PTAB E2E system.
• Institution decision: The status "Terminated-Settled" and the last modified date of 2026-05-18 suggest the case was likely instituted or was pending an institution decision when it settled. A specific institution decision date and reasoning are not available in public snippets.
• Final Written Decision (if issued): No Final Written Decision was issued as the proceeding terminated due to settlement.
• Settlement / termination: The proceeding was terminated as settled. The filing date of the IPR was 2024-12-20. The last modified date for the proceeding is 2026-05-18, indicating the settlement occurred sometime before or around this date. The specific terms of the settlement are confidential.
• Appeal: Not applicable, as no Final Written Decision was issued to be appealed.
• Defensive value: Since the proceeding settled before a final decision on the merits, no claims of US11537442 were invalidated. This means that a potential defendant facing assertion of this patent will need to conduct their own analysis regarding validity, as the PTAB has not provided an adjudication. The settlement indicates that at least one challenger (Microsoft Corporation) sought to invalidate the patent, but the dispute was resolved privately.

Strategic summary

All claims of US11537442 remain UNTESTED by a PTAB Final Written Decision. The sole IPR filed against this patent, IPR2025-00318 by Microsoft Corporation, was terminated due to a confidential settlement between the parties. This means no claims were canceled or sustained through a PTAB trial process. Therefore, the patent has not been narrowed through IPR.

Regarding the estoppel landscape, § 315(e)(2) generally bars petitioners (and their privies) from raising any ground they raised or reasonably could have raised only if a final written decision is issued. Since IPR2025-00318 terminated in a settlement, it's unlikely that statutory estoppel under § 315(e)(2) applies to Microsoft Corporation or its privies concerning this specific IPR. However, the private settlement agreement might include contractual estoppel clauses that prevent Microsoft from challenging the patent again. For any other defendant, all prior-art grounds remain available for potential challenge in a new IPR, as no claims were adjudicated. There is no clear pattern of multiple IPR filings by the same petitioner or aggressive PTAB appeals by the patent owner yet, given only one terminated proceeding. Unified Patents is noted as having filed the PTAB case IPR2025-00318, indicating a defensive aggregator's involvement.

Recommended next steps

• Since IPR2025-00318 was terminated-settled, there is no PTAB Final Written Decision to link to for claim invalidation.
• Given that all claims of US11537442 are untested by PTAB, a defendant currently being asserted against should thoroughly evaluate the patent's validity, potentially considering filing a new IPR if strong prior art can be identified.
• Accessing the publicly available documents for IPR2025-00318 on the PTAB E2E system (e.g., the petition and any institution decision if it was issued before settlement) could provide insights into the initial invalidity arguments raised by Microsoft Corporation.
• The involvement of Unified Patents suggests a prior art search was conducted for the IPR, and reviewing their petition (if accessible) could be a starting point for any new validity analysis.
• Monitor any further litigation related to US11537442 to identify additional prior art or claim constructions that may inform a defensive strategy.

US patent 11537442, titled "Application runtime determined dynamical allocation of heterogeneous compute resources," describes a method and system for efficiently distributing sub-tasks within a heterogeneous computing environment. The patent's core innovation lies in using runtime information gathered by daemons to dynamically adjust the assignment of sub-tasks to computation nodes and booster nodes across multiple computing iterations, aiming to optimize overall task computation.

Below is an analysis of the most relevant prior art cited in US11537442, including full citations, dates, brief descriptions, and potential anticipation under 35 U.S.C. § 102.

Most Relevant Prior Art for US11537442

1. EP2442228A1 / US20130282787A1 (and related WO 2012/049247 A1)

• Full Citation: EP2442228A1 (published April 18, 2012) and US20130282787A1 (published October 24, 2013). These documents refer to the same underlying invention as WO 2012/049247 A1, which is explicitly mentioned in US11537442.
• Publication/Filing Date: The priority date for WO 2012/049247 A1 is October 13, 2010. EP2442228A1 was published on April 18, 2012, and US20130282787A1 on October 24, 2013.
• Brief Description: This prior art describes a cluster computer architecture with computation nodes and boosters connected via a communication interface. It introduces a resource manager responsible for dynamically assigning boosters and computation nodes to each other during runtime.
• Potential Anticipation (35 U.S.C. § 102): While WO '247 provides a flexible arrangement for assigning boosters to computation nodes, the present invention (US11537442) states that WO '247 "does not address how to distribute tasks between computation nodes and boosters." Therefore, it is unlikely to fully anticipate claims related to the dynamic distribution of sub-tasks based on runtime feedback for optimization in subsequent iterations. However, elements of Claim 1 of US11537442, particularly the general concept of a "heterogeneous computing system comprising a plurality of computation nodes and a plurality of booster nodes" and a "resource manager for assigning... booster nodes and... computation nodes to each other," may find partial correspondence in WO '247. The distinction lies in the dynamic reallocation of sub-tasks and the use of runtime information from daemons for iterative optimization, which are key inventive steps in US11537442.

2. US 2017/0262319 A1

• Full Citation: US 2017/0262319 A1 (publication date not explicitly stated in the provided text, but it's a 2017 publication).
• Publication/Filing Date: The patent itself does not specify the filing date, but the publication date is 2017.
• Brief Description: This reference describes runtime processes that can fully or partially automate the distribution of data and mapping of tasks to computing resources. However, it notes that a "tuning expert," a human operator, might still be needed for mapping actions to available resources. It primarily describes how a given application can be mapped onto a computing hierarchy.
• Potential Anticipation (35 U.S.C. § 102): US 2017/0262319 A1 focuses on the initial mapping and distribution of tasks, potentially requiring human intervention. US11537442, in contrast, emphasizes dynamic alteration of sub-task distribution during runtime based on feedback from daemons for subsequent iterations. Therefore, while US 2017/0262319 A1 might anticipate aspects of initial task assignment (e.g., as mentioned in the description of how an initial distribution might be determined in US11537442), it is less likely to anticipate the iterative, feedback-driven dynamic reassignment of sub-tasks by an application manager as claimed in US11537442. Specifically, claims 1, 2, 3, 4, and 9 of US11537442, which detail the use of "information relating to the processing of the plurality of sub-tasks" to "generate a further distribution" and the dynamic alteration by an "application manager" and "resource manager," would likely distinguish from US 2017/0262319 A1 due to the lack of explicit dynamic, iterative feedback-based optimization at runtime.

3. "Dynamic Process Management with Allocation-internal Co-Scheduling towards Interactive Supercomputing” by Clauss et al. (COSH 2016)

• Full Citation: Clauss et al. “Dynamic Process Management with Allocation-internal Co-Scheduling towards Interactive Supercomputing”, COSH 2016 Jan. 19, Prague, CZ.
• Publication/Filing Date: January 19, 2016.
• Brief Description: This paper is incorporated by reference in US11537442 for its description of "dynamic process management" and daemons. A daemon in the context of US11537442 is an application running as a background process capable of providing information used for dynamic allocation.
• Potential Anticipation (35 U.S.C. § 102): This non-patent literature reference describes daemons and dynamic process management, which are foundational concepts utilized by US11537442. While it establishes the presence of daemons and their ability to provide information, US11537442 explicitly states that the arrangement of WO '247 (which Clauss et al. builds upon) "does not address how to distribute tasks between computation nodes and boosters." Therefore, while Clauss et al. likely anticipates the existence and function of daemons for gathering information (relevant to claim 5 and 8), it is less likely to anticipate the specific method of using that daemon-provided information to iteratively adjust sub-task distribution for optimization as detailed in claims 1, 2, 3, 4, 7, 9, and 10 of US11537442.

4. "The DEEP Project An alternative approach to heterogeneous cluster-computing in the many core era” by Eicker et al. (Concurrency Computat.: Pract. Exper. 2016)

• Full Citation: Eicker et al. in “The DEEP Project An alternative approach to heterogeneous cluster-computing in the many core era”, Concurrency Computat.: Pract. Exper. 2016; 28:2394-2411.
• Publication/Filing Date: Published online July 27, 2015.
• Brief Description: This paper further describes the arrangement of WO '247, detailing a heterogeneous system with computation nodes and booster nodes connected by a switchable network. It discusses "taskifying" an application by annotating code with pragmas and labels to indicate scalable parts for booster processing.
• Potential Anticipation (35 U.S.C. § 102): Eicker et al. describes the concept of "taskifying" and initial allocation based on code annotations, which could relate to the initial distribution described in US11537442, especially the aspect of an operator estimating scalability (as mentioned in the detailed description). This could potentially anticipate aspects of Claim 6, where "the first distribution is determined based on a rating provided in source code for each sub-task." However, similar to the other references, it does not explicitly disclose the dynamic, runtime feedback-driven iterative adjustment of sub-task distribution that forms the core of US11537442's claims. The Eicker et al. paper focuses on the initial "taskifying" and offloading, not the continuous runtime optimization through feedback.

In summary, the cited prior art establishes the background of heterogeneous computing systems with computation and booster nodes, resource management, and the use of daemons for information gathering, and initial task mapping through code annotation. However, US11537442 distinguishes itself by claiming a method and system for dynamically generating a further distribution of sub-tasks for subsequent computing iterations based on runtime information relating to the processing of previous iterations, a crucial element not fully disclosed or rendered obvious by the identified prior art.

To analyze the obviousness of US patent 11537442 under 35 U.S.C. § 103, we will consider the claims of the patent and combinations of the provided prior art references, explaining the motivation for a person having ordinary skill in the art (PHOSITA) to combine them. The core of US11537442 is a method and system for dynamically allocating heterogeneous compute resources by iteratively adjusting the distribution of sub-tasks based on runtime performance information.

Key Features of US11537442 (from Claims 1 and 9, and description):

1. A heterogeneous computing system with computation nodes and booster nodes.
2. Processing a computation task comprising a plurality of sub-tasks.
3. In a first computing iteration, assigning and processing sub-tasks in a first distribution.
4. Using information relating to the processing of sub-tasks (e.g., from daemons operating in the nodes) to generate a further distribution of sub-tasks for a further computing iteration.
5. An application manager receives this information and determines the further distribution.
6. A resource manager may determine initial assignments and dynamically alter further distributions and node assignments based on the application manager's input.

Prior Art References:

• WO 2012/049247 A1 (WO '247): Describes a cluster computer architecture comprising a plurality of computation nodes and a plurality of boosters connected via a communication interface. It explicitly states that a resource manager is responsible for assigning one or more of the boosters and computation nodes to each other in a dynamic manner during runtime. However, it explicitly "does not address how to distribute tasks between computation nodes and boosters."

Obviousness Analysis under 35 U.S.C. § 103

The independent claims (Claim 1 and Claim 9) of US11537442 relate to a method and system for dynamic, feedback-driven adjustment of sub-task distribution in a heterogeneous computing environment. A compelling argument for obviousness can be made by combining the teachings of WO '247, Eicker et al., US 2017/0262319 A1, and Clauss et al.

Combination 1: WO '247 + Eicker et al. + US 2017/0262319 A1 + Clauss et al.

1. Heterogeneous System and Dynamic Node Assignment (WO '247):
   WO '247 clearly discloses a heterogeneous computing system comprising computation nodes and booster nodes connected via a communication interface. It also teaches that a resource manager dynamically assigns these nodes to each other during runtime. This forms the foundational system for US11537442.

2. Initial Task Distribution (Eicker et al. and US 2017/0262319 A1):
   WO '247 explicitly states that it "does not address how to distribute tasks between computation nodes and boosters." This missing element creates a clear motivation for a PHOSITA to seek methods for task distribution.

   • Eicker et al. provides a solution by describing how applications are "taskified" via developer annotations (pragmas and labels) to indicate which parts are "highly scalable" and "to be processed by a booster." This directly teaches a method for creating a first distribution of sub-tasks based on their suitability for different node types, as mentioned in Claim 6 of US11537442.
   • US 2017/0262319 A1 further reinforces this by describing "runtime processes that can fully or partially automate the distribution of data and mapping of tasks to computing resources" onto a "given computing hierarchy." This provides additional motivation and means for a PHOSITA to implement an initial, automated distribution of sub-tasks across the heterogeneous resources of WO '247.

   Motivation for combination: A PHOSITA, faced with the stated deficiency of WO '247 (lack of task distribution mechanism), would naturally look to known techniques for distributing tasks in heterogeneous environments. Eicker et al. and US 2017/0262319 A1 provide precisely such mechanisms, offering an initial, potentially semi-automated or programmer-guided, distribution for the system of WO '247.

3. Dynamic Refinement of Task Distribution using Runtime Information (Clauss et al.):
   Having established an initial distribution of tasks, a PHOSITA in the field of high-performance computing would understand that initial distributions might not be optimal and that performance can vary dynamically. Therefore, there would be a strong motivation to optimize and adapt this task distribution during runtime for improved efficiency and resource utilization.

   • Clauss et al. is cited by US11537442 as disclosing "daemons as addressed herein" for providing information for "Dynamic Process Management with Allocation-internal Co-Scheduling towards Interactive Supercomputing." These daemons can report "information relating to the processing of sub-tasks" and a "current state of the respective processing entity," as described in US11537442's detailed description.
   • The concept of "dynamic process management" inherently suggests collecting runtime information and using it to make adjustments.

   Motivation for combination: It would be obvious for a PHOSITA, building a system based on WO '247 (with initial task distribution from Eicker et al. and/or US '319) to incorporate a feedback mechanism for performance optimization. Using daemons, as taught by Clauss et al. and explicitly cited by US11537442 for dynamic process management and information provision, to gather runtime metrics (e.g., loading, execution time, resource utilization, as implied by Claim 8) and then using this information to generate a further distribution for subsequent iterations (the core of Claims 1 and 9) would be a logical and predictable step to improve the efficiency of task processing in a heterogeneous, dynamically managed environment. The overall objective of such a system is optimal performance, and iterative refinement based on feedback is a well-known engineering principle for achieving this.

4. Application Manager and Resource Manager Interaction (Claims 2, 3, 4, 9, 10):
   US11537442 describes an application manager receiving information and determining further distribution (Claim 2, 9), and a resource manager dynamically altering distributions and node assignments based on this input (Claim 3, 4, 10). These are architectural choices for implementing the dynamic adjustment. In a system with a resource manager (WO '247) and mechanisms for task distribution (Eicker et al., US '319), and a need for dynamic optimization based on feedback (Clauss et al.), the provision of an application manager to coordinate task-level adjustments and feed these back to the resource manager (which already handles dynamic node assignments in WO '247) would be a straightforward and obvious design implementation for a PHOSITA. WO '247's resource manager already "dynamically alters assignment of the plurality of computation nodes and the plurality of booster nodes to each other during the computation of the computation task". Using the new performance information to inform this existing dynamic assignment capability is merely applying known functionality in an expected way.

Conclusion on Obviousness:

Claims 1 and 9 of US11537442, and their dependent claims, would be obvious to a PHOSITA given the combination of WO '247, Eicker et al., US 2017/0262319 A1, and Clauss et al.

• WO '247 establishes the heterogeneous system and the dynamic assignment of nodes by a resource manager.
• Eicker et al. and US 2017/0262319 A1 teach initial methods for distributing tasks (taskifying via annotations or runtime automation) across such a heterogeneous system, addressing a known deficiency of WO '247.
• Clauss et al. teaches the use of daemons for providing runtime information to enable "dynamic process management."
• A PHOSITA would be motivated to combine these to achieve an optimized task distribution. After an initial task distribution (Eicker et al./US '319) on the heterogeneous system (WO '247), collecting runtime performance data via daemons (Clauss et al.) to iteratively refine the task distribution and instruct the already dynamic resource manager (WO '247) to adjust node assignments accordingly, is a logical and obvious step to improve efficiency and resource utilization, which are well-known goals in parallel and high-performance computing. This combination covers the key steps of assigning sub-tasks in a first iteration, collecting information, and generating a further distribution for a further iteration.
