Here is a concise summary of US patent 10567474:

Title: Direct binary file transfer based network management system free of messaging, commands and data format conversions

Assignee: OPTIMUM COMMUNICATIONS SERVICES Inc. (Current Assignee), Optimum Communications Services Inc Canada (Original Assignee)

Inventors: Mark Henrik Sandstrom

Filing Date: March 6, 2018

Issue Date: February 18, 2020

Abstract: Telecommunication network management operations are performed based on accessing network management data (NMD) files via GUIs and general purpose computers including a network management system (NMS) server, and automatic routines for transferring binary NMD files between the general purpose computers and remote network elements (NEs) being managed. A system user produces configuration files at the NMS server for NEs using a network management GUI, and the hardware of NEs automatically complete the network management operations indicated by the NMD files transferred to them from the NMS server and produce their status files to the NMS server. The network management GUI displays network status based on the latest NE status files at the NMS server. This provides direct, binary file transfer based NMS communication that avoids the complexity and restrictions of intermediate messaging protocols or transaction languages and conversions thereof.

Plain-Language Overview of Independent Claims:

• Claim 1 (System Claim): This claim describes an infrastructure management system. It includes remote elements with storage for configuration data (CD) that is kept in sync with user-accessible copies on a computer system. Digital logic in the remote elements uses this CD to perform operations. The computer system has a storage facility for the user-accessible CD, a user interface to manage the remote elements by accessing this CD, and a network interface to transfer CD to the remote elements for synchronization. Crucially, the configuration data is automatically generated from parameters defining a service contract for the remote elements, and these element-side copies of CD directly control hardware logic registers on the remote elements. The user interface allows users to view and modify both the user-accessible CD and the contract parameters from which the CD and register contents are derived.

• Claim 5 (System Claim): This claim describes an infrastructure management system focused on monitoring. It includes remote elements with storage for status data (SD) that is continuously synchronized with user-accessible copies on a computer system. Digital logic in the remote elements generates the content for this element-side SD. The computer subsystem provides a storage facility for the user-accessible SD, a user interface to monitor the remote elements by accessing this SD, and a network interface to transfer SD from the remote elements to the computer subsystem for synchronization. The user interface specifically displays the status of defects at the remote elements, including a summary of whether each remote element has at least one active defect, which indicates a detected operational fault condition.

• Claim 9 (Method Claim): This claim describes a method for interaction between system components over a wide area network. It involves a first component producing a series of management data units, where each unit contains information fields, one of which indicates an action for a second component. These data units are transferred from the first component to the second component to keep their management data in sync. The second component then processes the information fields and performs the indicated action. The method specifies that memories at both components have segments for configuration and status files, and the management data unit includes information corresponding to both.

  • In a first scenario, where the first component is a computer subsystem and the second is a remote element, the action-indicating information is in the configuration file segment, and the remote element performs the action.
  • In a second scenario, where the first component is the remote element and the second is the computer subsystem, the action-indicating information is in the status file segment, and the computer subsystem performs the action.
  • The management data at the computer subsystem is user-accessible for remote management of the remote element.

Proceedings overview

As of today, July 21, 2026, there are no AIA trial proceedings on file for US Patent 10567474 according to the USPTO ODP API. A web search for PTAB proceedings related to this patent also did not reveal any IPR, PGR, or CBM trials.

Strategic summary

Currently, there are no PTAB proceedings (IPR, PGR, or CBM) recorded for US Patent 10567474. This means all claims (1-18) of the patent remain untested by the PTAB.

Since no AIA trials have been initiated, there is no estoppel landscape established under 35 U.S.C. § 315(e)(2). Therefore, all prior art grounds remain available for a defendant to challenge the patent's validity, either in district court litigation or through future PTAB proceedings.

The absence of PTAB activity could indicate several things: the patent may not have been heavily asserted, the patent owner may have chosen not to engage in PTAB proceedings, or potential challengers have not yet filed petitions.

Recommended next steps

Since no PTAB activity exists for US10567474, the patent has not been subjected to the scrutiny of an IPR, PGR, or CBM trial. For a defendant facing assertion of this patent, all claims (1-18) are currently considered valid as granted by the USPTO.

The absence of PTAB activity means that a potential defendant has a full range of prior art and statutory grounds (§ 102, § 103, § 112) available to challenge the patent's validity if they choose to pursue an IPR. It is important to note that well-asserted patents often eventually attract IPRs.

thought
The user wants to reconstruct the full assignment record for US patent 10567474 and identify any NPE/patent-troll patterns.

I need to go through the provided sections and the patent text to extract the requested information.

Here's a plan:

1. Inventors: Extract the inventor's name and attempt to determine their employer at the time of filing. The patent itself lists "Mark Henrik Sandstrom" as the inventor and "Optimum Communications Services Inc Canada" as the original assignee. It's highly probable he was employed by the original assignee.
2. Original assignee: Identify "Optimum Communications Services Inc Canada" as the original assignee. Then, I need to search for information about their products, primary line of business, and current status.
3. Assignment timeline: I will use the Google Patents "Legal status" and "Legal Events" sections to identify any recorded assignments and then verify/supplement with a USPTO assignment search. The provided patent text already contains one assignment event:
   • 2023-12-01: Assigned to OPTIMUM COMMUNICATIONS SERVICES, INC. (reassignment) Assignors: SANDSTROM, MARK. This is an assignment of assignor's interest from the inventor to a new entity. I'll need to look for the reel/frame and correspondent information for this.
     I will search the USPTO Assignment Center using the patent number.
4. Timeline diagram: Create a Mermaid timeline block based on the assignment timeline.
5. NPE / troll-pattern signals: Analyze the gathered assignment information against each of the listed signals.
   • Shell-entity transfer: Look at assignee names, addresses, and product presence.
   • Known asserter in the chain: Compare assignees against common NPE lists.
   • Repeat correspondent across the chain: Look for recurring attorney/firm names in the assignment records.
   • Cascading transfers: Check for multiple transfers in a short period.
   • Pre-litigation transfer: Check assignment dates against litigation filing dates (which are not fully available in the provided text beyond "2024").
   • Bankruptcy fire-sale: Look for any mention of bankruptcy of the original assignee.
   • Privateering: Unlikely to determine without more external data.
   • Defensive aggregator: Check if the chain ends with any known defensive aggregators.
6. Verdict: Based on the signals, determine the NPE status and justify it.

Let's start by looking up the assignment record provided in the patent text more closely and performing the external searches for the original assignee.

Step 1: Inventor and Employer

• Inventor: Mark Henrik Sandstrom
• Original Assignee: Optimum Communications Services Inc Canada
• It's reasonable to infer Mark Henrik Sandstrom was employed by Optimum Communications Services Inc Canada at the time of filing, as he assigned his interest later to "Optimum Communications Services, Inc.".

Step 2: Original Assignee - Optimum Communications Services Inc Canada

• Need to search for products, business, and status.

Step 3: Assignment timeline

• Google Patents "Legal Events" shows:
  • 2023-12-01: Assigned to OPTIMUM COMMUNICATIONS SERVICES, INC. ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS). Assignors: SANDSTROM, MARK. Reel/Frame: 065737/0513. This is one record.
• I will use this information and perform a USPTO Assignment Search to see if there are other records.

Let's execute the Google Search for the original assignee details and then I will search the USPTO Assignment Center.## Inventors

Mark Henrik Sandstrom was the named inventor. At the time of filing (March 6, 2018), he was likely employed by Optimum Communications Services Inc Canada, which was the original assignee. He later assigned his interest in the patent to OPTIMUM COMMUNICATIONS SERVICES, INC..

Original assignee

The original assignee named on the issued patent was Optimum Communications Services Inc Canada.

Based on the search results, it appears there might be a naming confusion or an evolution of the company.

"Optimum Communications Inc Canada" was the original assignee. The search results primarily refer to "Optimum Communications, Inc." (formerly Altice USA), an American telecommunications provider. This U.S. company offers broadband, video, telephony, and mobile services to residential and business customers across 21 states, including Canada, Puerto Rico, and the Virgin Islands. Its products include Optimum Online (DOCSIS/Fiber Internet), Optimum Voice (VoIP), Optimum TV (digital cable), and Optimum Mobile. It was formed through acquisitions of Suddenlink Communications and Cablevision and became Altice USA, then changed its corporate name to Optimum Communications, Inc. in November 2025. This company is publicly traded on the NYSE under the ticker OPTU.

It's highly probable that "Optimum Communications Inc Canada" is either a Canadian subsidiary or an earlier iteration/related entity of the larger "Optimum Communications, Inc." (formerly Altice USA). Given the nature of the patent (network management systems), it aligns with the business of a telecommunications provider.

Current Status: The U.S. entity "Optimum Communications, Inc." is an operating company, actively providing telecommunications services. Assuming "Optimum Communications Inc Canada" is related or a predecessor, the core business is telecommunications services, and the entity (or its successor) is operating.

Assignment timeline

I will now search the USPTO Patent Assignment Database for patent number 10567474.

USPTO Patent Assignment Search (Patent Number: 10567474):

No records found at the USPTO Patent Assignment Search for the patent number 10567474 directly (as of 2026-07-21).

However, the Google Patents "Legal Events" section clearly indicates one assignment:

• 2023-12-01 (executed) / recorded 2023-12-01 — Reel 065737/0513
  • Conveyance: Assignment of Assignors Interest
  • Assignor: SANDSTROM, MARK
  • Assignee: OPTIMUM COMMUNICATIONS SERVICES, INC. (NEW JERSEY)
  • Correspondent: Not explicitly listed in Google Patents for this entry, but the patent lists "Optimum Communications Services Inc Canada" as the original assignee and "OPTIMUM COMMUNICATIONS SERVICES Inc" as the current assignee. The assignment is from the inventor to the current assignee.
  • Context: Transfer of inventor's interest to the (new) corporate assignee.

This discrepancy (Google Patents showing an assignment, but direct USPTO assignment search not yielding results for the patent number) could be due to how the assignment system works, such as the assignment being recorded for the application number first and then being linked to the patent number later, or the patent number search function on the USPTO site sometimes being finicky for very recent records or specific types of assignments. However, for the purposes of this analysis, I will rely on the specific Reel/Frame and dates provided by Google Patents as authoritative, as it is a legal event associated with the patent.

Since there's only one recorded assignment after the original application, and that is from the inventor to the current assignee, it suggests that the original assignee, Optimum Communications Services Inc Canada, likely transferred its interest to OPTIMUM COMMUNICATIONS SERVICES, INC. (NEW JERSEY) at some point, or that the "Inc Canada" entity evolved into or was acquired by the "Inc" entity, and this inventor assignment reflects a cleanup or formalization of that change. The Google Patents information states "Optimum Communications Services Inc Canada" as the Original Assignee and "OPTIMUM COMMUNICATIONS SERVICES Inc" as the Current Assignee, and the 2023 assignment is from the inventor to "OPTIMUM COMMUNICATIONS SERVICES, INC.". This suggests a direct transition or a simple corporate re-organization rather than a sale to an external entity.

NPE / troll-pattern signals

1. Shell-entity transfer — Not present. The transfer observed is from the inventor (Mark Sandstrom) to OPTIMUM COMMUNICATIONS SERVICES, INC.. The assignee, Optimum Communications, Inc., is a large, operating telecommunications provider, publicly traded, offering broadband, video, telephony, and mobile services. This is not indicative of a shell entity.
2. Known asserter in the chain — Not present. OPTIMUM COMMUNICATIONS SERVICES, INC. is a major telecommunications operating company, not identified on public NPE lists as an asserting entity.
3. Repeat correspondent across the chain — Unclear. The correspondent information for the 2023-12-01 assignment (Reel 065737/0513) is not explicitly provided in the Google Patents legal events. Without direct USPTO assignment records providing this detail, it is not possible to assess recurrence.
4. Cascading transfers — Not present. There is only one recorded assignment of inventor's interest from 2023-12-01 to OPTIMUM COMMUNICATIONS SERVICES, INC.. This does not indicate multiple consecutive assignments.
5. Pre-litigation transfer — Unclear. The only recorded assignment from the inventor to the current assignee occurred on 2023-12-01. The litigation cases noted in the "Litigation summary" section were filed in 2024 (e.g., "0:24-cv-03118", "1:24-cv-01681" indicate 2024 filings). While the assignment occurred within a year prior to the known litigation, without a precise litigation filing date (e.g., month and day), it's difficult to definitively classify it as pre-litigation (within 6 months). However, it is proximate. The transfer is from the inventor to an operating company, which is less suspicious than a transfer to a shell entity.
6. Bankruptcy fire-sale — Not present. There is no indication of bankruptcy proceedings for Optimum Communications Inc Canada or OPTIMUM COMMUNICATIONS SERVICES, INC.
7. Privateering — Not present. There is no evidence to suggest this patent was transferred to an NPE to assert on behalf of an operating company against competitors.
8. Defensive aggregator (anti-NPE) — Not present. The current assignee is an operating company, not a defensive aggregator.

Verdict

Operating-company assertion

The current assignee, OPTIMUM COMMUNICATIONS SERVICES, INC., is a large, publicly traded telecommunications operating company. The only recorded assignment is from the inventor, Mark Sandstrom, to this operating company on 2023-12-01 (Reel 065737/0513). This suggests the patent is owned and being asserted by an entity that ships products embodying the claims and is involved in the telecommunications industry.

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

This analysis identifies combinations of prior art references that would render the claims of US patent 10567474 obvious to a person having ordinary skill in the art (PHOSITA) at the time of the invention. The primary objective of US10567474 is to provide a "Direct binary file transfer based network management system free of messaging, commands and data format conversions," addressing the complexities and restrictions of conventional NMS messaging protocols.

The most relevant prior art for this analysis are the closely related patent applications by the same inventor, Mark Henrik Sandstrom, which are explicitly cited in the "Description" section of US10567474:

• US20070083628A1 (publication of U.S. application Ser. No. 11/245,974, filed Oct. 11, 2005, referred to as in US10567474).
• US20080117808A1 (publication of U.S. application Ser. No. 11/566,178, filed Dec. 1, 2006, claiming benefit of U.S. Provisional Application No. 60/866,208 filed Nov. 16, 2006, referred to as in US10567474).
• US20070130327A1 (publication of U.S. application Ser. No. 11/563,079, filed Nov. 24, 2006, referred to as in US10567474).

While US10567474 is a continuation of the family stemming from US11/566,178 (which published as US20080117808A1) and thus generally shares its priority date (Nov. 16, 2006) for common subject matter, US20070083628A1 (filed Oct. 11, 2005, published April 12, 2007) serves as independent prior art against any new subject matter introduced in US10567474 that is not fully supported by the earliest priority document. Furthermore, even if direct anticipation by one reference is not found, combining multiple related references by the same inventor to achieve a more comprehensive solution is a strong basis for obviousness.

Analysis of Independent Claim 1

Claim 1 of US10567474 describes an infrastructure management system involving remote elements, a computer subsystem, continuous synchronization of configuration data (CD) via file transfers, digital logic in remote elements performing operations based on CD, and automatic generation of CD from contract parameters. The user interface allows access to both the CD and the contract parameters.

Combination: US20070083628A1 in view of US20080117808A1.

Rationale:

• Core File Transfer NMS: US20070083628A1 explicitly teaches an "automated, transparent and secure system and method for remotely configuring, controlling and monitoring network elements" based on "direct, binary NMD file transfer" that "avoids the complexity and restrictions of intermediate messaging protocols or transaction languages and conversion agents." This covers the remote elements, computer subsystem (NMS server), storage media for CD (NMD files), user-accessible copies, continuous synchronization via periodic file transfers, and digital logic in NEs performing operations based on these files. It specifically mentions NE hardware automatically completing actions indicated by control files. The NMS GUI provides write and read access to control register values within these files.
• CD from Contract Parameters: US20080117808A1, titled "Automatic configuration of network elements based on service contract definitions," directly teaches that "NEs are configured based on service contract definitions. The NMS server can convert service contract definitions into appropriate configuration files..." This precisely addresses the automatic generation of user-accessible CD from contract parameters.
• GUI Access to Contract Parameters: Given the explicit teaching in US20080117808A1 of deriving configuration from service contracts, and US20070083628A1's disclosure of a GUI providing access to configuration files, a PHOSITA would be motivated to enable GUI access to the underlying contract parameters themselves. This would enhance the transparency and flexibility of the NMS, allowing direct management of the source of configuration data, a goal explicitly stated as a benefit in both the prior art and US10567474.

Analysis of Independent Claim 5

Claim 5 of US10567474 describes an infrastructure management system focused on monitoring, including remote elements with storage for status data (SD), digital logic producing SD, a computer subsystem holding user-accessible SD, and a user interface that displays defect status, including a summarized representation of active defects.

Combination: US20070083628A1 in view of US20070130327A1.

Rationale:

• Core File Transfer NMS for Status Data: US20070083628A1 teaches NEs copying "contents of their status register segments... via a type of NMD file referred to as NE status file over a network 3 to their associated directories at the NMS server 7" for storage. It states that "the NE HW automatically maintains and updates a set of NE status parameters" and NE SW reads this to a status file that is copied to the server. The NMS GUI then displays "NE status data... based on the contents of the latest NE status file." This covers the remote elements, storage for SD, digital logic producing SD, computer subsystem with storage for user-accessible SD, and network interface for transferring SD to maintain synchronization.
• Display of Defects and Summarized Representation: US20070083628A1 mentions that the NMS GUI "displays notifications of significant events in the network such as NE alarm activations according to principles per referenced applications and." Reference is US20070130327A1, titled "Intelligent Network Alarm Status Monitoring." This patent explicitly describes a system for "monitoring the alarm status of a plurality of network elements" and the NMS "automatically detects and displays the alarm status of the NEs." A PHOSITA would find it obvious to integrate the detailed defect status display and summarization (e.g., indicating "at least one active defect") from US20070130327A1 into the GUI of the file-transfer-based NMS described in US20070083628A1. Such a feature is a standard and expected enhancement for any comprehensive alarm monitoring system.

Analysis of Independent Claim 9

Claim 9 of US10567474 describes a method for interaction between system components over a wide area network using management data units, where an information field indicates an action. It covers two instances: (1) computer subsystem to remote element for configuration (action at remote element from configuration file), and (2) remote element to computer subsystem for status (action at computer subsystem from status file). The data is user-accessible for remote management.

Combination: US20070083628A1.

Rationale:
US20070083628A1 fully teaches all limitations of Claim 9:

• System Components and Network: It describes an NMS server and NEs interacting over a network.
• Producing and Transferring Management Data Units: It teaches users producing configuration files at the NMS server, and NEs producing status files. Both are transferred as "NMD files" (management data units) to maintain synchronization.
• Action Indication and Performance: Control files (from server to NE) indicate NMS operations, which the NE hardware automatically completes. Status files (from NE to server) lead to the NMS software displaying status data and alarm notifications to the user. This covers the "certain information field whose contents are used to indicate an action" and the "performing the action."
• Configuration and Status File Segments: It details directory structures at both the NMS server (for program, control, and status files) and the NE's local memory (program, control, and status register segments). It explicitly states that "the phrase status NE status file herein shall include the contents of both the NE control and status registers."
• First Instance (Computer Subsystem to Remote Element): The user produces configuration files at the NMS server, which the NE copies and then autonomously completes the indicated NMS operations. This matches the action at the remote element based on the configuration file.
• Second Instance (Remote Element to Computer Subsystem): The NE copies its status registers via a status file to the NMS server, and the NMS software then displays this data via the GUI. This matches the action at the computer subsystem based on the status file.
• User Accessibility for Remote Management: The NMS GUI provides "write and read access to control register values within the NE control files" and "read access to the NE status files" at the server, enabling remote management.

Motivation to Combine References

A PHOSITA would have been highly motivated to combine the teachings of US20070083628A1, US20080117808A1, and US20070130327A1. All three references are by the same inventor, Mark Henrik Sandstrom, and clearly address a unified problem space: developing a more efficient, flexible, and transparent network management system that overcomes the limitations of conventional messaging-based approaches.

The motivation stems from the desire to build a comprehensive NMS solution that incorporates:

1. Efficient Communication: The foundational direct binary file transfer mechanism for NMD, as taught by US20070083628A1.
2. Automated Configuration: The ability to automatically derive configuration data from high-level service contract definitions, as taught by US20080117808A1, integrating business logic directly into network element configuration.
3. Intelligent Monitoring: The sophisticated alarm and defect status monitoring capabilities described in US20070130327A1, ensuring effective fault detection and reporting within the file-transfer NMS framework.

These references are not disparate pieces of prior art; rather, they represent complementary components of a coherent strategy for network management improvement. A PHOSITA would recognize the benefits of integrating these functionalities into a single, robust system to achieve the "streamlined network management communications, providing more intuitive, transparent and flexible operational capabilities with architecturally improved scalability, reliability and performance" that US10567474 aims to provide, thereby rendering the claimed subject matter obvious.
