Here is a concise summary of US patent 11875275:

Title: Custom time series models in computer analytics systems

Assignee: The current assignee is Cisco Technology Inc. The original assignee was Splunk Inc.

Inventors: Koulick Ghosh and George TSIRONIS.

Filing Date: February 21, 2023.

Issue Date: January 16, 2024.

Abstract: The patent describes techniques for creating custom time series models within computer analytics systems. A computer system provides an abstraction layer to facilitate model creation. This involves receiving custom model parameters through a model creation wizard interface. The custom model definition is then transformed into a functional custom model using these parameters, which the computer system can subsequently execute to identify properties in data that are not explicitly present.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (Method): This claim describes a computer-implemented method. It involves a computer system receiving one or more user-defined parameters for a custom model through a "model creation wizard interface." The system then uses these parameters to convert the custom model's definition into an executable custom model. Finally, the computer system runs this custom model to discover characteristics or insights in data that are not immediately obvious or explicitly stated within the data itself.

• Independent Claim 9 (System): This claim defines a computer system configured to perform the method outlined in Claim 1. The system comprises one or more memories that store instructions, and one or more hardware processors that execute these instructions. The execution of these instructions causes the computer system to carry out the steps of receiving custom model parameters via a wizard interface, transforming the custom model definition into a custom model using those parameters, and then executing the custom model to identify implicit properties within data.

• Independent Claim 17 (Non-Transitory Computer-Readable Medium): This claim covers a non-transitory computer-readable medium (e.g., a hard drive, SSD). This medium stores instructions that, when processed by one or more hardware processors, direct a computer system to perform the same set of operations as described in Claim 1. Specifically, these operations include receiving custom model parameters through a model creation wizard interface, transforming the custom model definition into a custom model using these parameters, and executing the custom model to identify properties in data that are not explicitly present.

USPTO and CAFC 2026 Dockets:
The patent status indicates a pending PTAB (Patent Trial and Appeal Board) case, IPR2026-00263, which was filed in 2026. No specific dockets related to US11875275 were found for the Court of Appeals for the Federal Circuit (CAFC) in 2026 based on the provided information.

Proceedings overview

There is one AIA trial proceeding on file for US patent 11875275, which is currently active and in the "Pending" status. This means the patent's claims are still undergoing review by the PTAB, and no final decision has been rendered, so its defensive posture is currently uncertain.

IPR2026-00263 — SAGEMCOM BROADBAND SAS v. Cisco Technology Inc.

• Type: Inter Partes Review
• Filed: 2026-02-20
• Status: Pending – The petition has been filed and is awaiting a decision on institution by the PTAB.
• Judge panel: Not yet public, as the institution decision has not been issued.
• Petition grounds: Details of the challenged claims, specific prior art, and statutory bases (§ 102 / § 103 / § 112) are not publicly available at this early stage without reviewing the petition itself.
• Institution decision: Not yet issued. The statutory deadline for the PTAB to decide whether to institute the IPR is typically within six months of the petition's filing date, which would be around August 20, 2026.
• Final Written Decision: Not issued, as the proceeding is still in the pre-institution phase.
• Settlement / termination: No settlement or termination has been reported.
• Appeal: No appeal has occurred, as no Final Written Decision has been issued.
• Defensive value: This IPR is in its initial stages. While its outcome is uncertain, the existence of an active IPR means that the validity of the patent's claims is currently being challenged. A defendant facing assertion of this patent should closely monitor this proceeding, as a successful IPR could invalidate some or all of the asserted claims.

Strategic summary

The validity of US patent 11875275 is currently under challenge in a single Inter Partes Review, IPR2026-00263, filed by SAGEMCOM BROADBAND SAS. As the proceeding is still in the pre-institution phase, all claims of the patent are currently UNTESTED by the PTAB. There are no claims that have been canceled or sustained through an AIA trial. The Patent Owner is Cisco Technology Inc..

Given the early stage of IPR2026-00263, the estoppel landscape is not yet defined. If the IPR is instituted and proceeds to a Final Written Decision, the petitioner (and its privies) would be estopped from asserting grounds raised or that reasonably could have been raised in the IPR concerning any claims found unpatentable. However, for other potential defendants, the full range of prior-art grounds remains available until an institution decision is made and any claims are ultimately adjudicated. There are no apparent patterns of multiple IPR filings by the same petitioner on this specific patent, nor any signals regarding aggressive appeals by the patent owner or involvement of defensive aggregators like Unified Patents based on the current information for this patent.

Recommended next steps

• Monitor IPR2026-00263 closely: The key upcoming milestone is the institution decision, expected around August 20, 2026. This decision will determine whether the PTAB will proceed with a full review of the challenged claims. Access to the petition and any preliminary responses filed would provide insight into the specific claims challenged, the prior art asserted, and the arguments presented by both parties.
• If you are a defendant, obtain and review the petition in IPR2026-00263 to understand the specific prior art and arguments being used to challenge the patent. This information can inform your own invalidity contentions if you are involved in co-pending litigation.
• If the IPR is instituted, continue to track the trial schedule, including any upcoming oral hearings and the expected Final Written Decision due date (typically one year from institution).
• Search for "IPR2026-00263" directly on the USPTO PTAB E2E (or its successor P-TACTS) portal for access to public documents, including the petition, preliminary response, and ultimately the institution decision.

Most Relevant Prior Art for US Patent 11875275

1. US 9,130,971 B2 (Site-Based Search Affinity)

• Full Citation: US 9,130,971 B2, "SITE-BASED SEARCH AFFINITY", issued on September 8, 2015.

• Publication/Filing Date: Issued: September 8, 2015. (The filing date is not explicitly stated in the provided text but can be found via a USPTO search for this patent number.)

• Brief Description: This patent describes a data intake and query system, such as the SPLUNK® ENTERPRISE system, which collects, indexes, and searches machine data, including "time series data." It provides functionalities for anomaly detection and prediction of future outcomes using "models" to identify information not explicitly present in the input data. It also highlights a limitation of such systems where customers are often restricted to a fixed set of models provided by enterprise software creators, implying the difficulty or impossibility for users to create custom models.

• Potential Anticipation (35 U.S.C. § 102): US 9,130,971 B2 does not directly anticipate the independent claims of US 11875275. While it discloses a system for analyzing time series data and using models to identify implicit properties in data, it explicitly identifies the lack of user-defined custom model creation as a limitation. Therefore, it does not disclose the key elements of US 11875275, which are:

  • Receiving user-defined parameters for a custom model via a model creation wizard interface.
  • Transforming the custom model definition into an executable custom model using these parameters.
  • Executing that custom, user-defined model to identify properties not explicitly present.

  Instead, US 9,130,971 B2 serves as a foundational reference for the general problem space and the capabilities of existing analytics systems, against which the novelty of US 11875275 (i.e., enabling custom model creation through a wizard) can be highlighted. It directly provides the context for the "problem" that US 11875275 aims to solve.

Obviousness Analysis under 35 U.S.C. § 103 for US Patent 11875275

This analysis identifies combinations of prior art references and common general knowledge that would render the independent claims of US Patent 11875275 obvious to a person having ordinary skill in the art (PHOSITA) before the patent's priority date of October 17, 2019. The core invention of US11875275 is facilitating the creation and execution of custom time series models in computer analytics systems using a "model creation wizard interface" to receive user-defined parameters.

Prior Art References Considered

1. US 9,130,971 B2 (Site-Based Search Affinity), issued September 8, 2015: This patent, frequently referenced within the text of US11875275, describes a robust computer analytics system (e.g., the SPLUNK® ENTERPRISE system) designed for collecting, indexing, and searching massive volumes of machine data. It handles events associated with specific points in time ("time series data"), uses flexible schemas for on-the-fly information extraction, and supports functionalities like anomaly detection and prediction of future outcomes based on data analysis. The patent explicitly notes that "models are executed by computers to analyze the data and detect information about the users and hardware that directly or indirectly cause the data," and that "anomaly detection is used for systems to detect fraud, security threats, and the existence of faulty data." While it broadly refers to "models" for these purposes, it also states that "creating a model is generally performed by enterprise software providers. When the enterprise software is provided to the customers or used by customers, the customers are often only able to use a fixed set of models created by the enterprise software provider."

2. Common General Knowledge (CGK) of User Interface Design for Complex Software (pre-Oct 2019): Prior to October 2019, "wizard interfaces" were a well-established and ubiquitous design pattern in software development for guiding users through multi-step processes, configurations, or creations that required inputting various parameters. This was a common approach to simplify complex tasks for users who might not have expert-level technical knowledge.

3. Common General Knowledge (CGK) of Analytical Software and Custom Model Creation (pre-Oct 2019): Before October 2019, various analytical software tools (e.g., Microsoft Excel with its Data Analysis ToolPak, statistical packages like SPSS or SAS, or open-source environments like R and Python with libraries such as scikit-learn or statsmodels) routinely provided users with interfaces to define parameters for diverse statistical, machine learning, and time series models. These tools allowed users to specify inputs, select model types, and define specific parameters (e.g., window sizes, thresholds, regression coefficients) to generate results that identified properties not explicitly present in the raw input data (e.g., trends, correlations, anomalies, predictions).

Obviousness Argument

The independent claims of US Patent 11875275 (Claims 1, 9, and 17) cover a method, system, and non-transitory computer-readable medium, respectively, for:

1. Receiving user-defined parameters for a custom model via a model creation wizard interface.
2. Transforming the custom model definition into an executable custom model using these parameters.
3. Executing the custom model to identify properties in data not explicitly present.

Combination: US 9,130,971 B2 in view of Common General Knowledge of UI Wizards and Analytical Software

A PHOSITA, at the time of the invention, would have found the claimed invention obvious by combining the teachings of US 9,130,971 B2 with common general knowledge in software engineering and data analytics.

Motivation to Combine:
The US 9,130,971 B2 patent clearly describes sophisticated computer analytics systems that ingest and process massive amounts of machine data, enabling searches and supporting high-level analytical tasks like anomaly detection and predicting future outcomes. However, it identifies a limitation where "creating a model is generally performed by enterprise software providers" and customers "are often only able to use a fixed set of models." A PHOSITA would recognize this as a significant impediment to users needing specialized or custom analyses for their unique operational contexts. There would be a strong motivation to enhance such a powerful data analytics platform by enabling end-users to create their own custom analytical models. This would empower a broader user base to extract more specific and relevant insights from their machine data without requiring extensive programming or data science expertise for every custom scenario.

Application to Claim Elements:

• "receiving, by a computer system, one or more user-defined parameters of a custom model definition via a model creation wizard interface;"

  • US 9,130,971 B2 discloses a "computer system" for data intake and query, processing machine data and events, and capable of applying "models" for analysis like anomaly detection.
  • CGK of UI Wizards: The idea of using a "wizard interface" to gather "user-defined parameters" for a software function was well-known and routinely applied to simplify complex configuration or creation processes in enterprise software, including those related to data analysis, reporting, and system setup. Extending this established UI paradigm to define parameters for custom analytical models would be a straightforward application of known techniques to address the identified problem of limited user customization.
  • CGK of Analytical Software: Existing analytical software commonly provided interfaces (some wizard-like) for users to input parameters for various models. Therefore, incorporating such a user-friendly parameter input mechanism into an enterprise analytics system would be an obvious design choice for improving usability and customizability.

• "transforming, by the computer system, the custom model definition into a custom model using the one or more user-defined parameters;"

  • US 9,130,971 B2 describes models used in the system, implying the system's ability to execute them. The patent further explains that "Programming is used to transform the structure into a workable model that a computer can interpret."
  • CGK of Analytical Software and Software Engineering: The step of taking user-defined parameters (e.g., statistical coefficients, machine learning algorithm choices, time-window settings) and configuring or generating executable code or logic to create a functional "custom model" is a fundamental and inherent aspect of any configurable analytical software. A PHOSITA would understand that once parameters are received, the system must process them to create an operable model instance. Modern analytics platforms frequently employed techniques like dynamic code generation, script execution, or API calls to underlying analytical engines based on user inputs.

• "executing, by the computer system, the custom model to identify one or more properties in data that are not explicitly present in the data."

  • US 9,130,971 B2 explicitly states that its models "detect information about the users and hardware that directly or indirectly cause the data," and that "the properties detected are not explicitly in the input data." It specifically mentions "anomaly detection" and "predict future outcomes" as examples of what models do.
  • CGK of Analytical Software: The primary purpose of any analytical model (statistical, machine learning, time series) is to derive insights, predictions, or classifications (i.e., "properties") that are not immediately obvious or "explicitly present" in the raw input data. Therefore, executing a custom model to achieve this goal is the expected and inherent function of such a model within any analytics system.

Conclusion

Based on the foregoing, a PHOSITA would have been motivated to combine the established data analytics capabilities of a system like that described in US 9,130,971 B2 with the common general knowledge of using wizard interfaces for simplified parameter input and the known functionalities of analytical software to define and execute custom models. This combination would lead to the obvious development of a system and method that allows users to define custom time series models through a wizard, transform these definitions into executable models, and then run them to identify implicit properties in data, thereby overcoming the acknowledged limitation of fixed enterprise-defined models. The claimed invention, therefore, would have been obvious under 35 U.S.C. § 103.
