Obviousness

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

This analysis identifies combinations of prior art references that would render claims 1-13 of US Patent 11190590 obvious to a person having ordinary skill in the art (PHOSITA), drawing upon the grounds asserted in IPR2026-00148 and the general knowledge and definitions presented within the patent itself. The core concept of US11190590 is a "System and method for server based control" that replaces dedicated local gateways for building or vehicle control with a remote server, thereby implementing gateway or control functionalities in the cloud. The patent explicitly states that this approach offers "much better cost, reliability and level of service."

A key piece of prior art cited within US11190590 itself, demonstrating the state of the art and providing a strong motivation for such a combination, is the paper "Home Network with Cloud Computing for Home Management" by Katsuya Suzuki and Masahiro Inoue (IEEE 15th International Symposium on Consumer Electronics, 2011, pages 421-425). This paper describes "a prior-art architecture involving moving limited management functions of a home gateway onto network cloud," directly addressing the motivation to leverage cloud computing for home management functions.

Combinations of Prior Art and Obviousness Rationale

The following combinations of prior art, as outlined in the IPR petition grounds, would render claims 1-13 obvious:

1. Claims 1-13 over US Patent 8,026,804 (Kovler) in view of US Patent 7,088,235 (Dietz) and US Patent 7,224,271 (Lee).

   • Kovler (US 8,026,804): This patent generally relates to a system and method for remote control of devices. A typical remote control system would involve a local controller or gateway managing various devices within an environment (e.g., home appliances, sensors) and potentially allowing remote access via a network.
   • Dietz (US 7,088,235): This patent describes a network for remote control of systems in a building, likely detailing the communication infrastructure and mechanisms for controlling devices within a building from a remote location.
   • Lee (US 7,224,271): This patent focuses on a home management and security system, which would involve sensors, actuators, and a central control unit (gateway) to monitor and manage aspects of a home environment.

   Motivation for Combination: A PHOSITA, familiar with the concepts disclosed in Kovler (remote device control), Dietz (building system control networks), and Lee (home management with sensors/actuators and a control unit), would have been motivated to combine these teachings. The inherent desire to improve "cost, reliability and level of service" for such systems, as articulated in US11190590, would lead a PHOSITA to consider offloading gateway or control functionalities to a server (e.g., a cloud server). The Suzuki and Inoue paper from 2011 explicitly provides this motivation by disclosing "moving limited management functions of a home gateway onto network cloud." Such a combination would leverage the scalability, centralized management, and reduced local hardware requirements offered by server-based solutions, which were well-understood benefits of cloud computing by the priority date.

2. Claims 1-13 over Kovler in view of Dietz and US Patent Application Publication 2008/0262660 (Schultz).

   • Kovler (US 8,026,804): As above, generally relates to remote control of devices.
   • Dietz (US 7,088,235): As above, describes a network for remote control of systems in a building.
   • Schultz (US 2008/0262660 A1): This patent application publication pertains to methods and systems for managing remotely accessible devices. This would likely describe how devices in a local network can be accessed and controlled from a remote location.

   Motivation for Combination: Similar to the previous combination, a PHOSITA would recognize that combining Kovler's remote control principles, Dietz's building network, and Schultz's remote device management capabilities would result in a comprehensive system for controlling devices in a building remotely. The motivation to centralize "gateway or control functionalities" on a "server" for "better cost, reliability and level of service" (as described in US11190590) would be clear. The Suzuki and Inoue paper further reinforces this motivation by explicitly suggesting the movement of home gateway management functions to a network cloud. Implementing Schultz's management system on a cloud server rather than a purely local gateway would be an obvious design choice to achieve these known advantages.

3. Claims 1-13 over Kovler in view of US Patent 7,859,380 (Friel) and US Patent 7,657,333 (Decker).

   • Kovler (US 8,026,804): As above, generally relates to remote control of devices.
   • Friel (US 7,859,380): This patent describes a system and method for controlling appliances through a network. This would detail how various home or building appliances (such as those listed in US11190590's definitions, e.g., water heaters, HVAC systems, refrigerators) are connected and controlled via a network.
   • Decker (US 7,657,333): This patent focuses on an integrated home control system with remote access. This would involve a system that integrates various home functions and allows for their control from a location external to the home.

   Motivation for Combination: A PHOSITA would be motivated to combine Kovler's general remote device control with Friel's specific appliance control over a network and Decker's integrated home control with remote access. The progression from local control and limited remote access to a more robust, scalable, and cost-effective solution via server-based control would be obvious. The recognized benefits of cloud computing, such as improved "reliability and level of service" (as mentioned in US11190590), would drive a PHOSITA to move the central control and gateway functions described by Friel and Decker to a "server" or "cloud computing" environment, as taught by the Suzuki and Inoue paper.

4. Claims 1-13 over US Patent 8,248,229 (Stiesdal) in view of Dietz and Lee.

   • Stiesdal (US 8,248,229): This patent describes a system and method for controlling wind turbines. While specific to wind turbines, it would inherently disclose a robust control system for monitoring sensors and actuating components in a remote or distributed environment. This would include principles of data acquisition from sensors, processing control logic, and issuing commands to actuators.
   • Dietz (US 7,088,235): As above, describes a network for remote control of systems in a building.
   • Lee (US 7,224,271): As above, focuses on a home management and security system, involving sensors, actuators, and a central control unit.

   Motivation for Combination: A PHOSITA would recognize that the control principles for a complex system like a wind turbine, as taught by Stiesdal (monitoring, control logic, actuation), are generally applicable to other environments requiring similar control, such as "a building or in a vehicle" as described in US11190590. Applying Stiesdal's control methodology to building systems (Dietz) and home management (Lee) would be a straightforward adaptation. Furthermore, the motivation to improve the "cost, reliability and level of service" for such comprehensive control systems, as consistently highlighted in US11190590, would lead a PHOSITA to deploy the overarching control and gateway functionalities on a remote "server" (cloud), following the teaching of the Suzuki and Inoue paper to move gateway management functions to the cloud. The general benefits of cloud computing in terms of scalability and reduced local infrastructure would also make this combination an obvious choice.

In summary, for each of these combinations, the individual prior art references establish the components of a control system, including sensors, actuators, networks, and local gateways for remote access. The explicit teachings in the Suzuki and Inoue paper, coupled with the well-known advantages of cloud computing (e.g., cost-effectiveness, scalability, reliability, and centralized management), would provide ample motivation for a PHOSITA to relocate or implement the "gateway or control functionalities" of these systems on a remote "server" rather than solely on a dedicated local device, thereby rendering claims 1-13 of US11190590 obvious.
