Obviousness

The obviousness analysis under 35 U.S.C. § 103 for US patent 12010174B2 requires identifying combinations of prior art references that would render the claims obvious to a person having ordinary skill in the art (PHOSITA) at the time of the invention (priority date January 9, 2012), along with a motivation to combine them. A PHOSITA is presumed to have access to all pertinent prior art and to be capable of combining references in a predictable way.

The independent claims (1, 11, 12, and 22) of US12010174B2 essentially describe a system and method for server-based control of field units (sensors and/or actuators) in an environment (building or vehicle) via a local router and an external server on the Internet. The crucial aspect is the external server implementing the control logic.

Potential Combinations of Prior Art and Rationale for Obviousness:

1. Combination of "Home Network with Cloud Computing for Home Management" (Suzuki and Inoue, 2011) and general knowledge of wireless mesh networks (e.g., Borcoci tutorials, IEEE 802.11s).

• Suzuki and Inoue (2011): This paper, specifically incorporated by reference in US12010174B2, describes "a prior-art architecture involving moving limited management functions of a home gateway onto network cloud". It proposes a home network system architecture utilizing cloud computing for home management. [cite: The full patent text, under "a prior-art architecture involving moving limited management functions of a home gateway onto network cloud is described in the paper entitled: “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, which is incorporated in its entirety for all purposes as if fully set forth herein."] It explains that basic and real-time applications are handled by M2M communication between household devices in a local network, while "sophisticated and non-real-time applications are managed on the network cloud and control the household devices via internet". This directly teaches the concept of an external server (network cloud) managing and controlling devices (household devices) in an environment (home) via the internet.
• Wireless Mesh Networks (WMNs): The patent explicitly mentions WMNs, IEEE 802.11s, and cites tutorials by W. Steven Conner and Eugen Borcoci as known in the art. [cite: The full patent text, under "a Wireless Mesh Network (WMN) and Wireless Distribution Systems (WDS) are known in the art to be a communication network made up of clients, mesh routers and gateways organized in a mesh topology and connected using radio.", "WMNs are standardized in IEEE 802.11s and described in a slide-show by W. Steven Conner, Intel Corp. et al. entitled: “IEEE 802.11s tutorial” presented at the IEEE 802 Plenary, Dallas on Nov. 13, 2006, in a slide-show by Eugen Borcoci of University Politehnica Bucharest, entitled: “Wireless Mesh Networks Technologies: Architectures, Protocols, Resource Management and Applications”, presented in INFOWARE Conference on Aug."] These references detail WMN architectures, protocols (including routing), and applications for residential and enterprise environments, emphasizing benefits like low deployment costs, high scalability, and fault resiliency. They also describe mesh routers as access points for users inside homes and for connecting clients with different radio technologies. The concept of "field units" encompassing sensors and actuators is also broadly disclosed within the patent as known technology.
• Motivation to Combine: A PHOSITA, seeking to implement a robust, scalable, and cost-effective home or building control system, would be motivated to combine the cloud-based management architecture described by Suzuki and Inoue with the established technology of wireless mesh networks. WMNs offer decentralized management and interoperability among devices, making them ideal for connecting a diverse set of "field units" (sensors and actuators) within an environment. The motivation would be to leverage the benefits of cloud computing for complex control logic and data processing (as taught by Suzuki and Inoue) while using WMNs for reliable and flexible local connectivity for sensors and actuators, thereby extending the reach and robustness of the control system. The combination would address the limitations of a dedicated hardware gateway in each environment, as explicitly stated in the patent's own disclosure. [cite: The full patent text, under "a dedicated hardware gateway is required to control the wireless network in each environment. The disclosure describes how the dedicated gateway can be replaced by a cloud server, offering much better cost, reliability and level of service."]

How this combination renders claims obvious:

• Claim 1 (System for controlling devices in an environment): Suzuki and Inoue teach the external server (cloud) implementing management functions and controlling household devices via the internet. The WMN references teach the local network (mesh routers) connecting various devices (field units, including sensors and actuators). Combining these, the external server's control logic would process data from WMN-connected sensors and send commands to WMN-connected actuators, thereby forming the claimed system. The "router" in the claim is clearly a "mesh router" from the WMN prior art, which serves to connect devices in the home and to external networks like the Internet.
• Claim 11 (Method for controlling devices in an environment): The method steps of the server receiving data, executing control logic, and sending commands are directly taught by Suzuki and Inoue in the context of cloud-based home management. Applying this method over a WMN as the local network, also taught in the prior art, would be a straightforward implementation.

2. Combination of "Home Network with Cloud Computing for Home Management" (Suzuki and Inoue, 2011) and general knowledge of vehicle control systems and remote communication.

• Suzuki and Inoue (2011): As noted above, this reference teaches cloud-based management and control of devices in a "home" environment.
• Vehicle Control Systems and Remote Communication: The patent itself defines "environment control networks" broadly, stating the environment can be a "house, agricultural farm, city traffic systems etc." and that the controller can allow "automatic control or control by the user via the Internet". [cite: The full patent text, under "Environment control networks are networks of sensors and controller which provide an optimized solution for an environment control. The environment can be a house, agricultural farm, city traffic systems etc.", "the controller will allow automatic control or control by the user via the Internet."] Prior art existed for vehicle control systems, including remote access. For example, the description of "Entry systems for vehicles that utilize image authentication" that include a peripheral monitoring device to detect a person approaching the vehicle, which is "known in the conventional art" in Japanese Patent Publication Laid-Open No. 2003-138817, implies remote monitoring and control. Furthermore, a "Vehicle control system, server, and vehicle control method" published in 2021 (though a later publication, it references "conventional art" and earlier applications) discusses controlling vehicle doors and recognizing the presence and motion of people, which implicitly involves sensors and actuators, and could involve remote server interaction. Another prior art request from 2018 also discussed a "method for controlling a service station related to a vehicle" which used a "back-end element" (server) to authenticate access rights and enable use of the service station via a "control element," and that the user interface element "enables the user to start a service of the service station." This further demonstrates the concept of remote, server-based control in a vehicle-related context.
• Motivation to Combine: A PHOSITA, observing the advantages of cloud-based control for home environments (as taught by Suzuki and Inoue), would naturally consider extending this paradigm to vehicle environments. The motivation would be to centralize and enhance the control and management capabilities of vehicle systems, similar to how it benefits home management, for example, for fleet management, diagnostics, or advanced driver-assistance systems. The move to an external server for control logic offers benefits like simplified maintenance and support, and potentially improved stability and data security, which would be highly desirable in a vehicle context. [cite: The full patent text, under "SaaS is becoming ever more common as a form of SA delivery over the Internet and is being facilitated in a technology infrastructure called “Cloud Computing”.", "the service is supplied and consumed over the internet, thus eliminating requirements to install and run applications locally on a site of a customer as well as simplifying maintenance and support."]

How this combination renders claims obvious:

• Claim 12 (System for controlling devices in a vehicle): The general concept of an external server controlling devices via a local network and router is present in Suzuki and Inoue for a "home." Extending this to a "vehicle" with its own local network, router, and field units (sensors and actuators) would be an obvious design choice, given the established knowledge of remote vehicle monitoring and control, and the general applicability of cloud computing to various "environments" for enhanced control and data management. [cite: 2, The full patent text, under "Environment control networks are networks of sensors and controller which provide an optimized solution for an environment control. The environment can be a house, agricultural farm, city traffic systems etc."]
• Claim 22 (Method for controlling devices in a vehicle): The method of an external server receiving data, executing control logic, and sending commands, as taught by Suzuki and Inoue for a home, would be directly applicable to a vehicle, with the "field units" being vehicle sensors and actuators.

General Considerations for Obviousness:

• PHOSITA Knowledge: A PHOSITA in 2012 would have understood the concepts of networked sensors and actuators, local gateways/routers, and the increasing capabilities of internet-connected servers (cloud computing) for managing and controlling distributed systems. The patent itself provides extensive definitions of these concepts as known in the art, including various network types (LAN, WLAN, PAN, WPAN, WAN, cellular), communication protocols (TCP/IP, ZigBee, Z-Wave), and diverse sensor and actuator types. [cite: The full patent text, under "Definitions"]
• Motivation to centralize control: The patent acknowledges the need to replace "dedicated hardware gateways" with "cloud servers" for "better cost, reliability and level of service". [cite: The full patent text, under "a dedicated hardware gateway is required to control the wireless network in each environment. The disclosure describes how the dedicated gateway can be replaced by a cloud server, offering much better cost, reliability and level of service."] This explicitly states the motivation that would drive a PHOSITA to combine existing technologies to achieve server-based control.
• Predictable Results: Moving control logic to an external server provides predictable benefits, such as scalability, remote access, centralized updates, and potentially offloading processing from local devices, which aligns with the motivations discussed. [cite: 9, The full patent text, under "SaaS is becoming ever more common as a form of SA delivery over the Internet and is being facilitated in a technology infrastructure called “Cloud Computing”.", "the service is supplied and consumed over the internet, thus eliminating requirements to install and run applications locally on a site of a customer as well as simplifying maintenance and support."]

In conclusion, the combination of prior art demonstrating cloud-based management of local networks and devices (e.g., Suzuki and Inoue) with existing knowledge of wireless mesh networks and general remote control systems, particularly in the context of the stated benefits of moving control to a server, would render the independent claims of US12010174B2 obvious to a person having ordinary skill in the art at the time of the invention.
