I. Introduction

This analysis examines the patentability of the claims of U.S. Patent No. 11,100,163 ('163 patent) under 35 U.S.C. § 103, which pertains to the non-obviousness requirement for patentability. An invention is considered obvious if the differences between the claimed invention and the prior art are such that the invention as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art (a "POSITA"). This analysis will consider combinations of prior art references to determine if they would render the claims of the '163 patent obvious.

The '163 patent, titled "Photographic memory," filed on November 29, 2018, generally discloses a system and method for capturing audio and other data, creating a searchable transcript, and associating it with metadata such as time and location. A key aspect of the invention, as detailed in the independent claims, involves presenting location-based advertisements to a mobile device user based on their location and spoken keywords.

II. Person Having Ordinary Skill in the Art (POSITA)

A person having ordinary skill in the art relevant to the '163 patent at the time of the invention (with a priority date of July 29, 2008) would have had a bachelor's degree in computer science, electrical engineering, or a related field, and several years of experience in mobile application development, location-based services, and speech recognition technologies. This individual would have been familiar with concepts such as GPS, client-server architectures, and targeted advertising.

III. Analysis of Independent Claims

For the purpose of this analysis, we will focus on the key limitations of independent claim 1:

• A system for presenting location-based information to a mobile electronic device: This establishes the context of the invention.
• A database system for storing location-based travel information and advertisements: This points to a repository of geographically relevant data.
• A server that automatically receives a location from a mobile device: This involves the device transmitting its coordinates.
• The server automatically retrieves location-based travel information: This is a core functionality of providing relevant data based on location.
• The server automatically retrieves a location-based advertisement...dependent on...the received location...and relevant to at least one spoken keyword: This is a crucial limitation combining location, advertising, and voice input.
• The server automatically presents the retrieved advertisement to the user: This is the final step of delivering the targeted ad.

IV. Prior Art and Motivation to Combine

A review of the prior art available before the '163 patent's priority date reveals several references that, in combination, suggest the obviousness of the claimed invention.

A. Combination of Prior Art for Obviousness

A compelling combination of prior art that would render the claims of the '163 patent obvious includes:

1. A primary reference disclosing location-based services and advertising on a mobile device.
2. A secondary reference teaching the use of speech recognition to identify keywords for search or command input.

B. Rationale for Combination

At the time of the invention in 2008, the field of mobile technology was rapidly advancing. It was well-established to provide users with location-based information, such as maps, points of interest, and weather. Concurrently, targeted advertising based on user data, including location, was a known business model for monetizing free services.

A POSITA would have been motivated to combine a system for location-based advertising with speech recognition for several reasons:

• Improving User Experience and Interface: By 2008, typing on mobile device keyboards was often cumbersome. Voice input was emerging as a more convenient and hands-free method for users to interact with their devices, especially while on the go, such as when driving. A POSITA would have seen the natural progression of applying voice commands to existing mobile applications to enhance usability.
• Enhancing Ad Targeting and Relevance: The effectiveness of advertising is highly dependent on its relevance to the user. A POSITA would have recognized that a user's spoken words are a strong indicator of their immediate interests and intent. Combining location data with spoken keywords would allow for a much more precise and timely delivery of advertisements, making them more likely to be acted upon. For example, a user in a commercial district who says "I'm hungry for pizza" presents a clear opportunity to serve an ad for a nearby pizzeria. This combination represents a predictable improvement in ad targeting technology.
• Applying a Known Technique to a Similar Problem: Speech recognition was already being used to convert spoken language into text for search queries on desktop computers and in early voice assistant applications. A POSITA would have found it obvious to apply this known technique of using speech-to-text for keyword identification to the existing domain of location-based mobile advertising. The motivation would be to simply extend a proven method of user input to a different but analogous platform to achieve a well-understood benefit.

V. Conclusion

The independent claims of U.S. Patent 11,100,163 appear to be obvious in light of the prior art available before its priority date. The combination of a system for delivering location-based advertisements on a mobile device with the use of speech recognition to identify user intent through spoken keywords would have been a natural and predictable advancement to a person of ordinary skill in the art in 2008. The motivation to combine these elements to improve user convenience and the effectiveness of advertising would have been readily apparent. Therefore, a strong argument for the invalidity of these claims under 35 U.S.C. § 103 can be made.
