Here's a concise summary of US Patent 12218934, "Contextual and risk-based multi-factor authentication":

Title: Contextual and risk-based multi-factor authentication

Assignee: Qomplx Inc (Current Assignee listed as QPX LLC and QOMPLX LLC after reassignment)

Inventors: Jason Crabtree, Andrew Sellers, Ian MacLeod

Filing Date: 2024-09-13

Issue Date: 2025-02-04

Abstract: A system for contextual and risk-based multi-factor authentication that includes a multi-dimensional time series data server to monitor and record network traffic data, and serve this data to other modules. A directed computation graph module receives this traffic data, determines a network traffic baseline, and calculates a required verification score for granting access. Users must then utilize a plurality of verification methods to build up their verification score to the required level to gain access.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (System Claim): This claim describes a system for contextual and risk-based multi-factor authentication. It consists of two main components:

  1. A multi-dimensional time series data server which has memory, a processor, and instructions to monitor and record network traffic data, and then provide this data to other parts of the system.
  2. A directed computation graph module which also has memory, a processor, and instructions. This module receives the network traffic data from the server, establishes a normal pattern (baseline) for network traffic, and then determines how high a "verification score" a user needs to achieve before they can access a network resource. This score determination is based, at least partially, on the network traffic baseline.
     The claim specifies that the user must use multiple verification methods to accumulate enough verification score to be granted access to the network resource.

• Independent Claim 7 (Method Claim): This claim outlines a method for contextual and risk-based multi-factor authentication, involving the following steps:

  1. A multi-dimensional time series data server monitors and records network traffic data.
  2. The multi-dimensional time series data server then provides this traffic data to other modules.
  3. A directed computation graph module receives the traffic data from the server.
  4. The directed computation graph module determines a network traffic baseline from the received data.
  5. The directed computation graph module determines a required verification score that a user must obtain to be granted access to a network resource, based at least partly on the network traffic baseline.
  6. The user is then required to use multiple verification methods to accumulate enough verification score to gain access to the network resource.

Legal Status and Litigation:
The patent is currently "Active".
As of the information available, the patent family "has litigation". Specifically, a PTAB (Patent Trial and Appeal Board) case, IPR2026-00182, has been filed and is currently pending. The petitioner for this IPR is "Unified Patents PTAB Data". There is also mention of the "First worldwide family litigation filed" via a Darts-ip link.

A search of CAFC dockets for 2026 did not immediately reveal specific dockets directly naming US12218934, which is not unusual as PTAB actions are distinct from CAFC appeals unless the PTAB decision is appealed. The provided CAFC search results are general information pages and a list of scheduled cases for May 2026, which does not include US12218934. Therefore, while PTAB litigation is confirmed, no direct CAFC litigation regarding this specific patent number in 2026 dockets has been definitively found through the performed search at this time.

As of April 26, 2026, known litigation involving US patent 12218934 is as follows:

Proceedings overview

There is one active AIA trial proceeding on US Patent 12218934. It is an Inter Partes Review (IPR) that has been instituted and is currently in the trial phase. This indicates that the patent is actively being challenged, and its claims are currently under review by the Patent Trial and Appeal Board (PTAB), which introduces uncertainty regarding the validity of the challenged claims for a defendant.

IPR2026-00182 — Microsoft Corporation v. QOMPLX LLC

• Type: Inter Partes Review
• Filed: 2025-12-30
• Status: Trial Instituted (The PTAB has decided to proceed with a full review of the challenged claims, meaning there is a reasonable likelihood that at least one challenged claim is unpatentable).
• Judge panel: Information not publicly available at this stage in the provided patent text or readily accessible through a quick general search.
• Petition grounds: Details regarding specific claims challenged, prior art references, and statutory bases (§ 102 / § 103 / § 112) are typically outlined in the institution decision. This information is not explicitly available in the provided patent text.
• Institution decision: Instituted. The institution decision date is not provided in the prompt, but the "last modified" date of 2026-05-26 indicates recent activity related to its "Trial Instituted" status. The reasoning for institution would generally be that the petitioner, Microsoft Corporation, demonstrated a reasonable likelihood that at least one challenged claim of US12218934 is unpatentable.
• Final Written Decision (if issued): Not yet issued, as the proceeding status is "Trial Instituted."
• Settlement / termination: Not applicable, as the proceeding is active in the trial phase.
• Appeal: Not applicable, as no Final Written Decision has been issued.
• Defensive value: This active IPR means that the claims challenged by Microsoft Corporation are currently undergoing a validity review. A defendant facing assertion of this patent should closely monitor the progress of IPR2026-00182, as a successful challenge could invalidate claims pertinent to the assertion, potentially weakening the patent owner's case.

Strategic summary

Currently, US Patent 12218934 has one active Inter Partes Review, IPR2026-00182, initiated by Microsoft Corporation. This IPR has been instituted, meaning the PTAB found sufficient merit in Microsoft's petition to proceed to trial. As the proceeding is still in the trial phase, no claims have been canceled or sustained yet; all challenged claims are currently UNTESTED pending the Final Written Decision. The specific claims under challenge are not detailed in the provided data.

Regarding the estoppel landscape, if IPR2026-00182 proceeds to a Final Written Decision, Microsoft Corporation (and its privies) would be estopped under 35 U.S.C. § 315(e)(2) from asserting in future district court litigation or other USPTO proceedings any ground of unpatentability that they raised or reasonably could have raised during this IPR with respect to the claims at issue. For other potential defendants, any prior art grounds not included in Microsoft's petition (or not reasonably discoverable by Microsoft) would theoretically remain available for separate challenges, provided they are not otherwise barred by other PTAB rules or timings. The information provided does not indicate any pattern signals such as multiple IPRs by the same petitioner or aggressive PTAB appeals by the patent owner, QOMPLX LLC. However, the presence of Microsoft Corporation as a petitioner signals a significant challenge.

Recommended next steps

As IPR2026-00182 is currently in the "Trial Instituted" phase, a defendant should closely monitor its progression. Key upcoming milestones would include the oral hearing (if scheduled) and, most importantly, the statutory one-year deadline for the Final Written Decision, which would typically be one year from the institution date. The institution decision for IPR2026-00182 would contain the exact claims challenged and the prior art relied upon.
It looks like the initial summary for IPR2026-00182 was good, but I can add more specific details regarding the petition grounds and confirm the patent owner from the search results. The judge panel is still not explicitly stated in the public snippets for this specific case, but I have a better understanding of the institution process.

Updated information for IPR2026-00182:

• Patent Owner: Qomplx LLC
• Petition grounds: Microsoft Corporation challenged claims 1-30 of US12218934 under 35 U.S.C. § 103 (obviousness).
  • Ground 1: Obviousness over Kirti (Patent 10,063,654). Petitioner argued that Kirti teaches all elements of the challenged claims, including analyzing historical user login activity to create a "baseline user profile," identifying "anomalous activity," and implementing "additional steps to authentication" such as "elevated authentication or OTP validation."
  • Ground 2: Obviousness over Kirti (Patent 10,063,654) in view of Coffin (a 2011 book titled "Expert Oracle and Java Security"). This ground asserted that Coffin provides explicit details for MFA implementation steps not explicitly covered by Kirti.
  • Additional Grounds: Obviousness challenges for claims 10 and 25 (related to virtual machines) based on Kirti and Coffin in further view of Vemulapalli (Patent 9,448,852), which teaches using virtual machines in cloud computing environments.
• Institution decision: The petition was filed on December 30, 2025. The status "Trial Instituted" means the PTAB determined there was a reasonable likelihood that at least one challenged claim is unpatentable. The institution decision date is not explicitly stated, but the trial was instituted. Director John A. Squires now handles all decisions on institution, primarily through summary notices that provide no information.

Let's integrate this into the response.

Constraint Checklist & Confidence Score:
All previous constraints are still met. I now have specific details on the petition grounds and confirmation of the patent owner. The judge panel is still not publicly available at this stage for this specific IPR.

Confidence Score: 5/5

Strategizing complete. I will now proceed with generating the revised response.## Proceedings overview

Strategic summary

Currently, US Patent 12218934 has one active Inter Partes Review, IPR2026-00182, initiated by Microsoft Corporation against patent owner QOMPLX LLC. This IPR has been instituted, meaning the PTAB found sufficient merit in Microsoft's petition to proceed to trial. As the proceeding is still in the trial phase, no claims have been canceled or sustained yet; all challenged claims (1-30) are currently UNTESTED pending the Final Written Decision. Microsoft has specifically challenged these claims under obviousness grounds, citing prior art references Kirti, Coffin, and Vemulapalli.

Regarding the estoppel landscape, if IPR2026-00182 proceeds to a Final Written Decision, Microsoft Corporation (and its privies) would be estopped under 35 U.S.C. § 315(e)(2) from asserting in future district court litigation or other USPTO proceedings any ground of unpatentability that they raised or reasonably could have raised during this IPR with respect to claims 1-30. For other potential defendants, any prior art grounds not included in Microsoft's petition (or not reasonably discoverable by Microsoft) would theoretically remain available for separate challenges, provided they are not otherwise barred by other PTAB rules or timings. The information provided does not indicate any pattern signals such as multiple IPRs by the same petitioner or aggressive PTAB appeals by the patent owner, QOMPLX LLC. However, the presence of Microsoft Corporation as a petitioner signals a significant challenge. The current trend at the PTAB, especially under Director Squires, shows a narrowing path to institution due to discretionary considerations, making institution itself a notable event.

Recommended next steps

As IPR2026-00182 is currently in the "Trial Instituted" phase, a defendant should closely monitor its progression. The PTAB has a statutory one-year deadline to issue a Final Written Decision from the date of institution. This means the Final Written Decision for IPR2026-00182 can be expected approximately by late 2026 or early 2027, given the petition was filed on 2025-12-30. The institution decision for IPR2026-00182 outlines that claims 1-30 are challenged based on obviousness over Kirti, and Kirti in view of Coffin, with additional challenges for claims 10 and 25 involving Vemulapalli. Reviewing the full institution decision (which is generally public on the USPTO PTAB E2E portal) would provide specific details about the Board's reasoning for institution and the strength of the petitioner's arguments.

NPE / troll-pattern signals

1. Shell-entity transfer — Present. The transfer from QOMPLX, INC. to QPX LLC (Reel 059957/0279, executed 2024-09-26) and subsequent name change to QOMPLX LLC (Reel 059958/0122, executed 2024-09-28) involves the creation of an LLC (QPX LLC, then QOMPLX LLC) which could potentially be a licensing-only entity, though further investigation into QOMPLX LLC's activities would be needed to confirm this definitively. The suffix "LLC" is common for such entities.

2. Known asserter in the chain — Not present. None of the assignees (Fractal Industries, Inc., QOMPLX, INC., QPX LLC, QOMPLX LLC) are identified as known asserters in the provided lists.

3. Repeat correspondent across the chain — Present. Matthew S. Stippich of Cantor Colburn LLP is listed as the correspondent for all four assignments: Reel 059952/0101 (2024-09-15), Reel 059954/0831 (2024-09-18), Reel 059957/0279 (2024-09-26), and Reel 059958/0122 (2024-09-28).

4. Cascading transfers — Present. There are four transfers/name changes within a very short period (September 2024). Specifically, the sequence of assignments from inventors to Fractal Industries, Inc. (2024-09-15), then a name change to QOMPLX, INC. (2024-09-18), then an assignment to QPX LLC (2024-09-26), followed by a name change to QOMPLX LLC (2024-09-28) all occurred within a 13-day span. This rapid succession of transfers and name changes, especially leading to an LLC, is a strong signal.

5. Pre-litigation transfer — Unclear. The patent issued on 2025-02-04. The assignments occurred in September 2024, prior to issuance. There is no information provided about any infringement suits.

6. Bankruptcy fire-sale — Not present. No information suggests the original assignee filed for bankruptcy.

7. Privateering — Unclear. No SEC filings or external coverage are provided to indicate privateering.

8. Defensive aggregator (anti-NPE) — Not present. The chain does not terminate at a known defensive aggregator.

Verdict

NPE — moderate confidence. The presence of a shell-entity transfer (QOMPLX, INC. to QPX LLC/QOMPLX LLC), coupled with cascading transfers (four transactions within 13 days in September 2024, all handled by the same correspondent), are strong signals of potential NPE activity. The use of an LLC in the final ownership step, especially after multiple rapid transfers, points towards an entity structured for licensing rather than product development.

Most Relevant Prior Art for US12218934

1. U.S. Pat. No. 11,757,872

• Full Citation: U.S. Pat. No. 11,757,872 (issued Sep. 12, 2023) to Crabtree et al., titled "CONTEXTUAL AND RISK-BASED MULTI-FACTOR AUTHENTICATION".
• Publication/Filing Date: Issued Sep. 12, 2023. This patent is a continuation of U.S. patent application Ser. No. 17/539,137, filed on Nov. 30, 2021.
• Brief Description: This patent describes a system and method for contextual and risk-based multi-factor authentication. A server dynamically determines a necessary verification score for user access to resources, based on context and risks (e.g., connection origin, unusualness of request). Users collect verification points through a plurality of verification methods. The system includes a multi-dimensional time series data server to monitor and record network traffic and a directed computation graph module to determine a network traffic baseline and the required verification score based on the baseline.
• Potential Anticipation (35 U.S.C. § 102): This patent has the exact same title and abstract description as US12218934, and is explicitly stated as a continuation of an earlier application in the same family. It fully anticipates Claim 1 (System) and Claim 7 (Method) of US12218934, as it describes all elements of the system and steps of the method. This suggests US12218934 is claiming the same invention, likely with minor claim language adjustments or as part of a continuing prosecution strategy.

2. U.S. Pat. No. 11,218,474

• Full Citation: U.S. Pat. No. 11,218,474 (issued Jan. 4, 2022) to Crabtree et al., titled "CONTEXTUAL AND RISK-BASED MULTI-FACTOR AUTHENTICATION".
• Publication/Filing Date: Issued Jan. 4, 2022. This patent is a continuation of U.S. patent application Ser. No. 16/856,827, filed on Apr. 23, 2020.
• Brief Description: Similar to US11757872B2, this patent describes a system and method for contextual and risk-based multi-factor authentication. It involves a server dynamically determining a verification score based on connection context and risks, and a user building up this score using multiple verification methods. The system incorporates a multi-dimensional time series data server for network traffic monitoring and a directed computation graph module for baseline determination and score calculation.
• Potential Anticipation (35 U.S.C. § 102): As another direct continuation with the identical title and abstract content, this patent also fully anticipates Claim 1 (System) and Claim 7 (Method) of US12218934.

3. U.S. Pat. No. 10,742,647

• Full Citation: U.S. Pat. No. 10,742,647 (issued Aug. 11, 2020) to Crabtree et al., titled "CONTEXTUAL AND RISK-BASED MULTI-FACTOR AUTHENTICATION".

• Brief Description: This patent details a system and method for contextual and risk-based multi-factor authentication, including a multi-dimensional time series data server for monitoring network traffic and a directed computation graph module for establishing a network traffic baseline and determining a required verification score. The user must achieve this score through various verification methods. The score depends on factors like connection origin and anomaly detection.
• Potential Anticipation (35 U.S.C. § 102): Being the earliest granted patent in this direct lineage with the same title and fundamental inventive concept, this patent fully anticipates Claim 1 (System) and Claim 7 (Method) of US12218934. The content of the provisional application 62/574,708 would be captured within this patent, establishing the earliest effective filing date for the "Contextual and Risk-Based Multi-Factor Authentication" invention.

4. U.S. Pat. No. 10,860,962

• Full Citation: U.S. Pat. No. 10,860,962 (issued Dec. 8, 2020) to Crabtree et al., titled "SYSTEM FOR FULLY INTEGRATED CAPTURE, AND ANALYSIS OF BUSINESS INFORMATION RESULTING IN PREDICTIVE DECISION MAKING AND SIMULATION".
• Publication/Filing Date: Issued Dec. 8, 2020. This patent is a continuation-in-part of U.S. patent application Ser. No. 15/141,752, filed on Apr. 28, 2016.
• Brief Description: This patent describes a business operating system that integrates data from various sources (sensors, network providers, web crawling) for analysis and transformation into task-optimized results using a directed computational graph. It performs predictive statistics and machine learning for forecasting and decision-making, including cyber security functions like detecting anomalous network behavior and mitigating cyberattacks. It specifically mentions continuous polling of incoming traffic data for anomalous activities and tailoring alerts to responding parties.
• Potential Anticipation (35 U.S.C. § 102): While not directly focused on multi-factor authentication, this patent discloses a "multi-dimensional time series data store module" (similar to the server in Claim 1 and 7) for network traffic data and a "directed computational graph module" (similar to the module in Claim 1 and 7) for analysis, including detecting "anomalous network behavior" which is a basis for determining verification score in US12218934. It also discusses predictive analysis using machine learning. Elements like "monitoring and recording a network's traffic data" and "determining a network traffic baseline from the traffic data" are strongly suggested. However, the explicit "requiring a user to use a plurality of verification methods to earn enough verification score" part of claims 1 and 7 is not directly present in its abstract, nor is the "determining a required verification score needed before granting access." Therefore, it likely anticipates some components of Claim 1 and 7 related to data processing and baseline determination, but not the entire MFA system and method.

5. U.S. Pat. No. 10,248,910

• Full Citation: U.S. Pat. No. 10,248,910 (issued Apr. 2, 2019) to Crabtree et al., titled "DETECTION MITIGATION AND REMEDIATION OF CYBERATTACKS EMPLOYING AN ADVANCED CYBER-DECISION PLATFORM".
• Publication/Filing Date: Issued Apr. 2, 2019. This patent is a continuation-in-part of U.S. patent application Ser. No. 15/237,625, filed on Aug. 15, 2016.
• Brief Description: This patent focuses on a system for detecting, mitigating, and remediating cyberattacks. It retrieves and analyzes network traffic data, predicting normal usage patterns and continuously polling for anomalous activities. It uses a multi-dimensional time series data store and a directed computational graph module for analysis. The system formulates a baseline network usage profile and provides recommendations to reduce the probability of cyberattacks and mitigate damage.
• Potential Anticipation (35 U.S.C. § 102): This patent clearly describes the components for "monitoring and recording a network's traffic data" and "determining a network traffic baseline from the traffic data" using a "multi-dimensional time series data store" and "directed computational graph module," as detailed in Claim 1 and Claim 7 of US12218934. However, it does not explicitly disclose the step of "determining a required verification score needed before granting access by a user to network resource based at least in part by the network traffic baseline" nor "requiring a user to use a plurality of verification methods to earn enough verification score." It likely anticipates the data collection and baseline generation aspects (parts of Claim 1 and Claim 7 related to the data server and graph module's initial functions), but not the specific application to contextual and risk-based MFA with verification scores and methods.

6. U.S. Pat. No. 10,204,147

• Full Citation: U.S. Pat. No. 10,204,147 (issued Feb. 12, 2019) to Crabtree et al., titled "SYSTEM FOR CAPTURE, ANALYSIS AND STORAGE OF TIME SERIES DATA FROM SENSORS WITH HETEROGENEOUS REPORT INTERVAL PROFILES".
• Publication/Filing Date: Issued Feb. 12, 2019. This patent is a continuation-in-part of U.S. patent application Ser. No. 15/091,563, filed on Apr. 5, 2016.
• Brief Description: This patent describes a system and method for capturing, analyzing, and storing time series data from various sensors. It uses a multi-dimensional time series data store module that can accommodate high-volume data surges and programming wrappers for sophisticated logic. The system analyzes and transforms this data using a directed computational graph.
• Potential Anticipation (35 U.S.C. § 102): This patent directly teaches the "multi-dimensional time series data server" and "directed computation graph module" components of Claim 1 and the "monitoring and recording a network's traffic data" and "serving the traffic data to other modules" steps of Claim 7. While it covers the foundational data handling and processing components, it lacks the specific application to determining a verification score for user access based on a network traffic baseline and the use of plurality of verification methods for MFA. Thus, it anticipates the underlying data infrastructure but not the specific MFA context of US12218934's independent claims.

However, it still does not fully disclose the "required verification score" for user access and the use of a plurality of verification methods for MFA to achieve that score, as central to Claim 1 and Claim 7 of US12218934. It provides strong anticipation for the data collection and anomaly detection aspects, forming a significant part of the context for the MFA system.

Summary of Anticipation:

The patents U.S. Pat. Nos. 11,757,872, 11,218,474, and 10,742,647 are all direct continuations with identical titles and descriptions. They represent the most relevant prior art and fully anticipate Claim 1 (System) and Claim 7 (Method) of US12218934 under 35 U.S.C. § 102, as they disclose the same invention. The earlier filing date of U.S. Pat. No. 10,742,647, which claims priority to the provisional application 62/574,708, effectively establishes the prior art date for the "Contextual and Risk-Based Multi-Factor Authentication" invention.

Other continuation-in-part patents and applications (e.g., US10860962B2, US10248910B2, US10204147B2, US20170371726A1, US20170124501A1, US20170124464A1) provide foundational technology for data collection, processing, baseline determination, and anomaly detection using multi-dimensional time series data servers and directed computational graphs. These would likely anticipate individual components or steps within Claim 1 and Claim 7 of US12218934, particularly those relating to the underlying data infrastructure and analytical capabilities. However, they generally lack the specific combination of these elements directed to dynamically determining a required verification score for user access based on a network traffic baseline and requiring a user to use a plurality of verification methods to obtain that score for multi-factor authentication. These could form the basis for obviousness rejections under 35 U.S.C. § 103, but not direct anticipation under § 102 for the entire independent claims of US12218934.

Obviousness Analysis of US Patent 12218934 under 35 U.S.C. § 103

This analysis assesses the obviousness of US Patent 12218934 ("Contextual and risk-based multi-factor authentication") under 35 U.S.C. § 103, considering the provided patent text and its cited prior art. The patent addresses the problem of over-reliance on a single method of multi-factor authentication (MFA) and the need for a system that dynamically determines verification requirements based on context and risk.

The independent claims of US12218934 are:

• Independent Claim 1 (System Claim): A system comprising a multi-dimensional time series data server (MTSDS) to monitor, record, and serve network traffic data; and a directed computation graph module (DCGM) to receive this data, determine a network traffic baseline, and determine a required verification score for user access based on the baseline. The user then uses a plurality of verification methods to build up the required score to gain access.
• Independent Claim 7 (Method Claim): A method involving steps of monitoring, recording, and serving network traffic data with an MTSDS; receiving this data and determining a network traffic baseline with a DCGM; determining a required verification score based on the baseline; and requiring a user to use a plurality of verification methods to earn enough score for access.

The effective priority date for the core subject matter of US12218934 traces back to at least October 28, 2015, through its chain of priority claims to U.S. patent application Ser. No. 14/925,974.

Identification of Prior Art and Their Teachings

Several prior art references, particularly those within the patent's own family and explicitly incorporated by reference, disclose components and functionalities highly relevant to the present invention:

1. U.S. Pat. No. 10,248,910 (US10248910B2), titled "DETECTION MITIGATION AND REMEDIATION OF CYBERATTACKS EMPLOYING AN ADVANCED CYBER-DECISION PLATFORM," filed on August 15, 2016, and claiming priority back to U.S. patent application Ser. No. 14/925,974 filed on October 28, 2015. This patent describes a system (a business operating system 100) that continuously retrieves and stores network traffic data using a "multidimensional time series data store 120". This system analyzes captured data to predict normal usage patterns and formulate a "continuously evolving baseline network usage profile". It further describes the analysis of network traffic and usage patterns using a "directed computational graph module 155" to detect "anomalous activities" to that baseline.
2. U.S. Pat. No. 10,204,147 (US10204147B2), titled "SYSTEM FOR CAPTURE, ANALYSIS AND STORAGE OF TIME SERIES DATA FROM SENSORS WITH HETEROGENEOUS REPORT INTERVAL PROFILES," filed on April 5, 2016, and also claiming priority to U.S. patent application Ser. No. 14/925,974. This patent details the functionality of a "Multiple dimension time series data store module 120" for receiving and storing streaming data from various sensors, including network service information captures. This directly supports the "multi-dimensional time series data server" component of US12218934.
3. U.S. patent application Ser. No. 14/925,974 (US20170124464A1), titled "RAPID PREDICTIVE ANALYSIS OF VERY LARGE DATA SETS USING THE DISTRIBUTED COMPUTATIONAL GRAPH," filed on October 28, 2015. This application, the earliest priority document, generally describes the use of distributed computational graphs for analyzing large datasets, which underpins the "directed computation graph module" used for baseline determination and anomaly detection.
4. General Knowledge of Multi-Factor Authentication (MFA): The background section of US12218934 explicitly states, "Multi-factor authentication (MFA) is widely used today as an additional verification step often used in conjunction with a traditional login and password as a way to further secure a user's online accounts. MFA methods commonly used today includes one-time use codes sent to a user's mobile device or email, confirming through a uniquely generated link sent to the user, or using authenticator devices and apps that generate a code on-demand". This confirms that the concept of MFA and various verification methods were well-known prior art.
5. General Knowledge of Risk-Based Authentication: Prior to 2015, the concept of adjusting authentication requirements based on the assessed risk of an access attempt (e.g., unusual location, unknown device, access to sensitive resources) was a recognized practice in network security.

Obviousness Combination and Motivation

A person having ordinary skill in the art (PHOSITA) in network security, around the earliest priority date of October 28, 2015, would have found the invention of US12218934 obvious by combining the teachings of:

• US10248910B2 (and its underlying priority applications like US14/925,974 and US10204147B2), which collectively describe a sophisticated system for real-time network traffic monitoring, baseline establishment, and anomaly detection.
• General knowledge of MFA systems and their various verification methods.
• General knowledge of risk-based authentication approaches.

Motivation for Combination:

The motivation for a PHOSITA to combine these prior art elements is explicitly articulated in the "Background of the Invention" section of US12218934: "What is needed is a system that uses a combination of verification methods so that over-reliance on a single, and possibly compromised, method is eliminated. Such a system should be able to dynamically determine the varying amounts of verification needed, based on the context and risks associated with the connection."

Specifically, the motivation would arise from:

1. Enhancing Security through Dynamic Risk Assessment: The network traffic monitoring, baseline analysis, and anomaly detection capabilities described in US10248910B2 provide a robust mechanism for assessing the real-time risk associated with an access request. A PHOSITA would be motivated to integrate this detailed risk assessment into existing MFA processes to strengthen security. If an access attempt deviates from a normal baseline (e.g., unusual origin, time, or resource access patterns), the system should respond with a commensurately higher authentication requirement.
2. Improving User Experience: Conversely, for routine, low-risk access attempts (e.g., a user accessing common resources from a known device within the corporate network during business hours), a PHOSITA would seek to reduce unnecessary authentication friction. By dynamically adjusting the "required verification score" based on a low-risk assessment from the network monitoring system, the user could achieve access with fewer or simpler verification methods, optimizing the user experience without compromising security.
3. Overcoming Limitations of Static MFA: The patent itself highlights the "fault" of "over-reliance on a single method of delivery" in conventional MFA. A PHOSITA, aware of this limitation, would find it obvious to use a "plurality of verification methods" and a "points-based system" where different methods contribute varying "verification points" to achieve a dynamically determined "required verification score". This directly addresses the vulnerability of a single, compromised factor by requiring a combination of factors, potentially of different types and strengths, based on the assessed risk.

Application to Claims 1 and 7:

The elements of Claims 1 and 7, concerning the MTSDS for monitoring network traffic, the DCGM for determining a network traffic baseline, and the subsequent determination of a required verification score, are directly taught or rendered obvious by US10248910B2 and related priority documents. The further step of requiring a user to use a plurality of verification methods to accumulate enough points for access is an obvious application of known MFA principles, enhanced by the dynamic risk assessment provided by the underlying network monitoring and analysis system. The specific verification methods detailed in US12218934 (e.g., biometrics, device ID, one-time codes) are also acknowledged as known in the art.

Therefore, a PHOSITA, faced with the recognized problem of inflexible and potentially insecure MFA systems, would have been motivated to combine the robust network traffic analysis and anomaly detection capabilities available in the prior art (e.g., US10248910B2, US10204147B2, US14/925,974) with existing MFA and risk-based authentication principles to create a system that dynamically adjusts authentication requirements based on real-time contextual and risk factors. This combination would lead to the claimed system and method in US12218934 with a reasonable expectation of success.

To determine the patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and the projected expiration date for US Patent 12218934, we need to analyze the information from the patent itself and consult relevant USPTO resources.

1. Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) is granted to compensate applicants for delays caused by the USPTO during the prosecution of a utility or plant patent application. The total PTA is added to the standard 20-year term from the earliest filing date. Factors leading to PTA include the USPTO failing to:

• Issue a first Official Action or notice of allowance within 14 months of filing.
• Issue an action within four months of an applicant's response.
• Issue the patent within four months of payment of the issue fee.
• Issue a patent within three years of the actual filing date (with some provisos).

The Google Patents page for US12218934B2 does not explicitly state the granted PTA. To get the precise PTA, one would typically need to examine the patent grant or the PAIR (Patent Application Information Retrieval) system on the USPTO website. However, based on the filing date of September 13, 2024, and the publication date of February 4, 2025, there was a relatively quick issuance. Without explicit PTA data, a precise calculation is not possible here.

2. Patent Term Extensions (PTE)

Patent Term Extension (PTE) is awarded to compensate for delays incurred in obtaining regulatory approval on a patented product, especially for drugs, biologics, or medical devices, under 35 U.S.C. § 156. PTE can extend a patent's life by up to five additional years.

US Patent 12218934, titled "Contextual and risk-based multi-factor authentication," is a software/computer-implemented invention related to network security. This type of patent is not typically eligible for PTE, as PTE is primarily for patents covering products subject to premarket government approval by regulatory agencies like the FDA. Therefore, it is highly unlikely that US12218934 has received or is eligible for PTE.

3. Continuation Applications, Divisional Applications, and Related Family Members

The "CROSS-REFERENCE TO RELATED APPLICATIONS" section of US12218934 provides a comprehensive list of its lineage, indicating that it is part of a large patent family:

• This application is a continuation of U.S. patent application Ser. No. 18/464,623, titled "RISK-BASED MULTI-FACTOR AUTHENTICATION," filed on Sep. 11, 2023.
• Which is a continuation of U.S. patent application Ser. No. 17/539,137, titled "CONTEXTUAL AND RISK-BASED MULTI-FACTOR AUTHENTICATION," filed on Nov. 30, 2021 (issued as U.S. Pat. No. 11,757,872 on Sep. 12, 2023).
• Which is a continuation of U.S. patent application Ser. No. 16/856,827, titled "CONTEXTUAL AND RISK-BASED MULTI-FACTOR AUTHENTICATION," filed on Apr. 23, 2020 (issued as U.S. Pat. No. 11,218,474 on Jan. 4, 2022).
• Which is a continuation of U.S. patent application Ser. No. 15/790,860, titled "CONTEXTUAL AND RISK-BASED MULTI-FACTOR AUTHENTICATION," filed on Oct. 23, 2017 (issued as U.S. Pat. No. 10,742,647 on Aug. 11, 2020).
• Which claims priority to U.S. provisional patent application 62/574,708, titled "CONTEXTUAL AND RISK-BASED MULTI-FACTOR AUTHENTICATION," filed on Oct. 19, 2017.

Additionally, Ser. No. 15/790,860 is also a continuation-in-part of several other applications, which themselves have complex lineages, indicating a large family of related patents focusing on underlying technologies such as distributed computational graphs and cyberattack detection:

• U.S. patent application Ser. No. 15/616,427 (filed Jun. 7, 2017)
• U.S. patent application Ser. No. 14/925,974 (filed Oct. 28, 2015)
• U.S. patent application Ser. No. 15/237,625 (filed Aug. 15, 2016, issued as U.S. Pat. No. 10,248,910)
• U.S. patent application Ser. No. 15/206,195 (filed Jul. 8, 2016)
• U.S. patent application Ser. No. 15/186,453 (filed Jun. 18, 2016)
• U.S. patent application Ser. No. 15/166,158 (filed May 26, 2016)
• U.S. patent application Ser. No. 15/141,752 (filed Apr. 28, 2016, issued as U.S. Pat. No. 10,860,962)
• U.S. patent application Ser. No. 15/091,563 (filed Apr. 5, 2016, issued as U.S. Pat. No. 10,204,147)
• U.S. patent application Ser. No. 14/986,536 (filed Dec. 31, 2015, issued as U.S. Pat. No. 10,210,255)
• U.S. patent application Ser. No. 14/925,974 (filed Oct. 28, 2015)

The earliest priority date for US12218934, based on the cross-references, is October 28, 2015 (from U.S. patent application Ser. No. 14/925,974, which is referenced twice). The provisional application 62/574,708 (filed Oct. 19, 2017) is claimed as priority by Ser. No. 15/790,860, which is later in the chain than the October 28, 2015 date. Therefore, the effective earliest filing date for term calculation is October 28, 2015.

4. Projected Expiration Date

For utility patents filed on or after June 8, 1995, the patent term generally expires 20 years from the date on which the application for the patent was filed, or if it claims priority to an earlier application under 35 U.S.C. §§ 120, 121, 365(c), or 386(c), 20 years from the filing date of the earliest such application.

Given that US12218934 claims priority back to an application filed on October 28, 2015 (U.S. patent application Ser. No. 14/925,974), the statutory 20-year term would be calculated from this earliest effective filing date.

Therefore, the projected expiration date is:
October 28, 2015 (earliest priority date) + 20 years = October 28, 2035.

This date does not include any potential Patent Term Adjustment (PTA), as that information is not explicitly provided. If PTA were granted, it would extend the expiration date beyond October 28, 2035. However, the Google Patents page already lists an "Anticipated expiration" of "2035-10-28". This indicates that no significant PTA was granted or that any granted PTA was offset by applicant delay, or that it is simply a calculation based on the 20-year term from the earliest priority date without factoring in specific adjustments.
