Obviousness

Obviousness Analysis of US Patent 9462410 Under 35 U.S.C. § 103

This analysis identifies combinations of prior art references that would render the claims of US patent 9462410 obvious to a person having ordinary skill in the art (PHOSITA) at the time of the invention (priority date January 8, 2014).

Core Invention of US9462410

US patent 9462410, titled "Providing service description," describes a two-phase method for a beacon device (first device 110) to provide a service description to a user terminal (second device 130) regarding a service accessible at a remote server (server 150). The primary problem addressed is the limited data capacity of short-range wireless advertising messages, such as those used in Bluetooth Low Energy (BLE). [Description]

The two phases are:

1. Preliminary Service Description: The first device broadcasts concise "preliminary service description" via advertising messages. This description is sufficient to cause an indication on the user interface of the second device, allowing the user to decide whether to request more information. [Claim 1]
2. Complementary Service Description: Upon a user-initiated request from the second device, the first device establishes a wireless short-range point-to-point connection. Over this connection, "supplementary information" is transmitted. This supplementary information either directly contains the "complementary service description" or provides information (e.g., a URL) to obtain it, thereby supplementing the preliminary description. [Claim 1]

The patent emphasizes that the first device merely provides the service description and not the service itself, which resides on a remote server apparatus. [Description]

Identified Prior Art References

The patent itself cites the following as background and for detailed protocol descriptions, establishing them as prior art:

• Bluetooth Specification Version 4.0, Specification Volume 3—Core System Package [Host volume] Part C, Section 11 (publication date June 30, 2010) (hereinafter "Bluetooth Spec 4.0 Part C"). This document describes the Bluetooth Low Energy (BLE) protocol, including the structure and limitations of advertising messages, connection initiation, and roles of advertiser/scanner/initiator. [Description]
• Bluetooth Specification Version 4.0, Specification Volume 3—Core System Package [Host volume] Part G (publication date June 30, 2010) (hereinafter "Bluetooth Spec 4.0 Part G"). This document describes the Generic Attribute Profile (GATT), which provides a framework for structured data exchange and service discovery over established BLE point-to-point connections. [Description]

In addition to these specific technical specifications, "common general knowledge" in the art at the priority date (2014) includes:

• The widespread use and understanding of Uniform Resource Locators (URLs) and Uniform Resource Indicators (URIs) for identifying and accessing resources, such as web pages, applications, or services, on remote servers over networks like the Internet. [Description]
• The concept of beacons or small, low-power devices broadcasting limited information to nearby mobile devices for various purposes (e.g., location data, sensory data). [Description]

Obviousness Argument for Claims 1, 9, 10, and 11

The independent claims (Claim 1: apparatus, Claim 9: arrangement, Claim 10: beacon method, Claim 11: user terminal method) all encapsulate the two-phase service description process. These claims would have been obvious in light of a combination of the Bluetooth Specification Version 4.0 (Parts C and G) and the common general knowledge of URLs/URIs and network services.

Elements Disclosed by Prior Art:

1. Broadcasting advertising messages with limited data (Preliminary Service Description): Bluetooth Spec 4.0 Part C explicitly details BLE advertising, where devices broadcast messages on advertising channels with a limited user data payload (e.g., up to 31 octets). [cite: Bluetooth Specification v4.0, Vol 3, Part C, Section 11] These messages can include "Advertising Data (AD) structures" such as service UUIDs or local names, which naturally serve as a "preliminary service description" to indicate basic information about an available service. [cite: Bluetooth Specification v4.0, Vol 3, Part C, Section 11.1]
2. Causing service indication on a user interface: It is inherent in the design of BLE-enabled scanning devices (e.g., smartphones) that they would process received advertising data and display relevant information (like device names or service types) on their user interface, enabling user interaction.
3. Receiving a user-initiated request for more information (Complementary Service Description): Bluetooth Spec 4.0 Part C describes "connectable advertising" where a scanning device (initiator) can respond to an advertisement by sending a CONNECT_REQ to establish a connection. [cite: Bluetooth Specification v4.0, Vol 3, Part C, Section 11.1.2] A user deciding to "select" an advertised service to get more details is a natural interaction with such a system.
4. Establishing a wireless short-range point-to-point connection: This is a core function of BLE. When an advertising device accepts a CONNECT_REQ, a point-to-point connection is established, with the initiator becoming the master and the advertiser the slave. [cite: Bluetooth Specification v4.0, Vol 3, Part C, Section 11.1.2]
5. Providing and transmitting supplementary information via the point-to-point connection: Once a BLE connection is established, Bluetooth Spec 4.0 Part G details the Generic Attribute Profile (GATT), which enables structured and more extensive data exchange. Services and their characteristics (containing data) can be discovered and read over this connection. [cite: Bluetooth Specification v4.0, Vol 3, Part G] This mechanism is perfectly suited for providing "supplementary information," including a "complementary service description."
6. Service accessible at a remote server apparatus: While BLE itself primarily deals with device-to-device communication, the concept of a "service" residing on a remote server and being accessed via a network (e.g., Internet, WLAN) was well-established. [Description]

Motivation to Combine:

A PHOSITA in the field of wireless communication in 2014, aware of the constraints of BLE advertising (limited message size, as noted in the patent's background [Description]), would have been motivated to devise a system for providing comprehensive service descriptions for remote services. The challenge was how to effectively advertise a service whose full details (including how to access it) exceeded the capacity of a single BLE advertising message.

The obvious solution would be to implement a two-phase approach, leveraging the distinct capabilities of BLE's advertising and connected modes:

• To overcome the advertising message size limitation, a PHOSITA would naturally use the limited advertising space for a brief, indicative "preliminary service description" (e.g., a service category UUID or a short name, as defined by Bluetooth Spec 4.0 Part C [cite: Bluetooth Specification v4.0, Vol 3, Part C, Section 11.1]). This maximizes the reach of the low-power broadcast for initial discovery.
• To provide the full details for a remote service, upon user interest (manifested by a request to connect), the PHOSITA would then establish a standard BLE point-to-point connection (Bluetooth Spec 4.0 Part C [cite: Bluetooth Specification v4.0, Vol 3, Part C, Section 11.1.2]). Over this connection, the more extensive data transfer capabilities offered by GATT (Bluetooth Spec 4.0 Part G [cite: Bluetooth Specification v4.0, Vol 3, Part G]) would be used to provide the "complementary service description."
• Crucially, if the actual service resides on a remote server, the logical content of this "complementary service description" would include a URL or URI (common general knowledge) to enable the user's device to access that remote service. This is the conventional and most efficient way to link to network resources.

This combination of existing technologies (BLE advertising, BLE connection, GATT, and URLs) would be readily apparent to a PHOSITA seeking to improve the utility of BLE beacons for advertising remote services. The outcome of such a combination—efficient initial discovery followed by detailed access information—would be entirely predictable. The patent's solution directly maps to combining these well-known elements to solve a recognized problem in a predictable manner.

Therefore, Claims 1, 9, 10, and 11, which describe this two-phase method for providing service descriptions using short-range wireless communication to link to a remote service, would have been obvious in light of the Bluetooth Specification Version 4.0 in combination with common general knowledge of network resource identification and access via URLs/URIs.
