Obviousness

Obviousness Analysis of U.S. Patent No. 10,299,071

This analysis evaluates the patentability of the independent claims of U.S. Patent No. 10,299,071 ("the '071 patent") under 35 U.S.C. § 103, which pertains to the non-obviousness requirement for a patent. The analysis is based on the provided prior art references.

A person having ordinary skill in the art (PHOSITA) at the time of this invention would likely have a background in computer science or a related field, with experience in mobile application development, client-server architectures, and familiarity with GPS and wireless network technologies.

Analysis of Independent Claims 1 and 11

Claim 1 describes a server-implemented method for temporarily sharing location between two users (an "Instant Buddy" relationship) based on a request and acceptance. Claim 11 describes the server system that performs this method.

These claims appear obvious in light of a combination of U.S. Patent Application Publication No. 2004/0203923 A1 (B.J. et al., hereinafter "'923") and U.S. Patent No. 6,819,919 B2 (Sirola et al., hereinafter "'919").

1. Core Technology Disclosed in Prior Art: The '923 application discloses the foundational server-based system for enabling mobile users to share their location information in a controlled manner, including the formation of groups. This provides the general framework for a central server managing location data between devices, as claimed in the '071 patent. The '919 patent specifically teaches a "Personal Locator Service" where a first user can request the location of a second user, and the system forwards this request to the second user, who must grant permission for their location to be shared.

2. Motivation to Combine: A PHOSITA, starting with the group-based location sharing system of '923, would recognize the need for more flexible, on-demand sharing scenarios that do not require pre-configured "buddy lists." For instance, a user needing temporary assistance (e.g., a tow truck, as described in the '071 patent's specification at column 8, lines 16-24) would not want to permanently add the service provider to a personal buddy list. The problem, therefore, is how to create a temporary, permission-based sharing link.

   The '919 patent provides a direct solution to this problem by disclosing a request-and-grant mechanism for location sharing. A PHOSITA would be motivated to integrate the permission-based system of '919 into the broader location-sharing framework of '923. This combination would create a service where users could establish temporary, mutually agreeable location-sharing sessions without being part of a permanent group.

3. Resulting Combination:

   • The server infrastructure for receiving and transmitting location data between mobile devices is taught by '923.
   • The specific workflow of one user initiating a request, the server notifying a second user, and the second user accepting or denying the request before sharing commences is taught by '919.
   • The "timeout" feature, which automatically terminates the Instant Buddy relationship (described in the '071 patent at column 8, lines 39-43), would be a simple and predictable design choice for a PHOSITA implementing a temporary sharing feature to ensure privacy and prevent unintended, prolonged tracking.

Therefore, the combination of '923 and '919 would have rendered the methods and systems described in claims 1 and 11 of the '071 patent obvious to a person of ordinary skill in the art.

Analysis of Independent Claim 20

Claim 20 describes a server-based method for managing a location-sharing group where a "supervisor" has special privileges, namely that the supervisor cannot be removed from the group by other members without a specific passcode. The supervisor can monitor the location of all group members.

This claim appears obvious in light of U.S. Patent No. 7,764,961 B2 (Morley, et al., hereinafter "'961") combined with common knowledge in the field of computer security.

1. Core Technology Disclosed in Prior Art: As noted in the prior art analysis, the '961 patent strongly anticipates the core elements of claim 20. It explicitly describes an "automatic location and status reporting system" that can be configured for parental or employer monitoring. This system allows a "supervisor" to track the location of individuals in their group.

2. Motivation to Combine/Modify: The '961 patent discloses the fundamental concept of a supervisory location-tracking group. The only element of claim 20 not explicitly detailed in the '961 patent's summary is the use of a passcode to prevent the supervisor from being deleted by a subordinate member. A PHOSITA tasked with implementing the supervisory system of '961 for its intended purpose (e.g., employee or child monitoring) would immediately recognize that the system would be ineffective if the person being monitored could simply disable the tracking by removing the supervisor from the group.

   Therefore, the motivation to prevent such removal is inherent in the very purpose of a supervisory tracking system. Using a passcode or password to protect administrative or "supervisor" privileges is a fundamental, well-known, and routine technique in computer and network security. It is not an inventive step but rather a standard implementation choice to secure a hierarchical system.

3. Resulting Combination: A PHOSITA would take the supervisory location monitoring system of '961 and apply the routine security measure of a passcode to prevent unauthorized changes to the group's supervisory structure. This combination of the '961 system with basic, common-knowledge security practices would result in the exact system described in claim 20.

Conclusion

The independent claims of the '071 patent appear to be obvious over combinations of the cited prior art. Claims 1 and 11 combine known server-based location sharing with a standard request-and-permission mechanism to create a temporary sharing session, a modification that would have been a predictable solution to a known need for more flexible location sharing. Claim 20 describes a supervisory tracking system that is substantially disclosed in the prior art, with the addition of a passcode-protection feature that constitutes a routine and obvious design choice for any such system.
