Obviousness

The "Prior Art" section of the Google Patents page for US11468497 explicitly lists "user," "input," "purchase," "search," and "website" as keywords, with a "Prior art date" of March 31, 2014. While no specific prior art documents are listed in this section, the patent's own detailed description acknowledges existing technologies and their limitations, which a person having ordinary skill in the art (PHOSITA) would have understood at the time of the invention.

The claimed invention of US11468497 primarily focuses on a "unified input field" that processes user input to determine intent (e.g., search or purchase) and then dynamically presents various options or executes actions, often streamlining multi-step processes into fewer interactions. This includes features such as:

• Receiving user input in a generic input field.
• Analyzing the input to determine user intent, such as a generalized non-purchasing search or a search with intent to purchase. The patent notes that "classification algorithms are often used in processing speech or phone calls" for intent determination, and this disclosure applies them to a "new classification domain" of unified input fields.
• Presenting a set of options based on the determined intent, which can include standard web searches, e-commerce searches, or "one-click" purchase options.
• Flexible user interface presentations for these options, such as drop-down/drop-up menus, tag clouds, or "tears" that peer into other websites or applications.
• Dynamically modifying the functionality and label of an "enter" or "search" button based on the analyzed intent (e.g., changing from "search" to "Purchase iPhone 5S, 64 GB, Gold").
• Resolving ambiguities in purchase requests by using user history, demographics, or popularity, and providing options to modify or cancel purchases.

The patent itself describes the following as existing or typical approaches prior to the invention:

• Dedicated Search Engines (Prior Art Concept A): Users input text into a search field (e.g., Google, Yahoo, Bing) and receive a list of results. These systems also include "autocomplete" features to suggest query completions.
• Dedicated E-commerce Websites (Prior Art Concept B): Users navigate to a specific e-commerce site (e.g., Amazon.com, Apple.com, eBay), enter search terms in a dedicated search field, and then proceed through multiple steps to make a purchase, often with "one-click" purchase options available after navigating to a specific product page.
• Browser-Integrated Multi-Source Search (Prior Art Concept C): Some web browsers (e.g., Mozilla Firefox) provide a search field allowing users to manually select from different search engines or websites (e.g., Google, Wikipedia, Yahoo, Bing, Amazon). The patent notes this as "cumbersome" due to manual switching.
• Keyword-Driven Multi-Source Search (Prior Art Concept D): Users can employ shortcut codes (e.g., "g Olympics" for Google, "b Olympics" for Bing, "z Olympics" for Amazon) within a general search field to direct queries to specific sources. The patent states these "require extra typing" and are "limited to a single search source".

A person having ordinary skill in the art (PHOSITA) in web development, user interface design, or information retrieval, facing the challenges of improving user experience and reducing interaction steps in online activities (especially for purchasing), would have been motivated to combine these known elements.

Here are combinations of these prior art concepts that would likely render the claims of US11468497 obvious:

1. Combination of Prior Art Concept A (Dedicated Search Engines with Autocomplete) + Prior Art Concept B (Dedicated E-commerce Websites with One-Click Purchase) + General Knowledge of Classification Algorithms:

• Motivation: A PHOSITA would be motivated to streamline the user's journey from searching for information about a product to purchasing it. The recognized inconvenience of navigating to separate websites and performing repetitive searches (as articulated by the patent itself when contrasting with existing methods) would drive this integration. Furthermore, the patent notes that classification algorithms were already "often used in processing speech or phone calls" for intent determination. It would be obvious to a PHOSITA to apply such known classification techniques to text input in a general search field to distinguish between informational searches and purchase intent.
• Obviousness Explanation: Given the existence of general search engines (Concept A) that provide information and autocomplete suggestions, and e-commerce sites (Concept B) that facilitate "one-click" purchases after an item is identified, it would be obvious to integrate these functionalities. A PHOSITA would consider developing a system where, upon receiving user input in a single field (like a web search bar), the system would automatically attempt to discern if the user intends to purchase. If purchase intent is high (e.g., "iPhone 5S 32 GB silver"), instead of just showing search results, the system could leverage the "one-click" purchase technology (from Concept B) to directly offer a purchase option, bypassing the need for the user to visit the e-commerce site, search again, and then locate the one-click button. The "classifier" described in the patent would be an obvious application of existing machine learning techniques to a new domain of intent analysis for web actions.

2. Combination of Prior Art Concept A (Dedicated Search Engines with Autocomplete) + Prior Art Concept C (Browser-Integrated Multi-Source Search) + General UI/UX Principles:

• Motivation: The patent highlights the "cumbersome" nature of manually selecting search sources in browser-integrated search fields (Concept C). A PHOSITA would seek to automate this selection and make it more intuitive. General UI/UX principles advocate for presenting relevant options to the user efficiently and with clear visual cues.
• Obviousness Explanation: Building on the idea of a search field that can query multiple sources (Concept C) and the dynamic suggestions of autocomplete (Concept A), it would be obvious to a PHOSITA to present these multi-source options, including direct purchase options (from Concept B, which is generally known in e-commerce), within the autocomplete dropdown menu as the user types. The patent describes presenting "one-click purchasing option in the listing of autocomplete options" and blending "autocomplete with purchasing options or other options such as jumps to other websites". This combines known autocomplete behavior with known multi-source querying and purchasing goals. Furthermore, employing varied visual presentations like drop-down for search and drop-up for purchase options, or using tag clouds with varying size and proximity to indicate relevance, would be obvious UI/UX design choices for presenting context-sensitive options in an organized and user-friendly manner.

3. Combination of Prior Art Concept B (Dedicated E-commerce Websites with One-Click Purchase) + General UI/UX Principles (Dynamic Buttons/Menus):

• Motivation: To reduce the number of user interactions required to complete an online purchase, especially when the user's intent to purchase is clear. Providing immediate and contextual feedback through dynamic UI elements is a common design goal.
• Obviousness Explanation: Knowing that e-commerce sites like Amazon offered "one-click" purchasing (Concept B), a PHOSITA would be motivated to bring this efficiency to the earliest point of user interaction possible. If a unified input field (as a common starting point for users) is used to discern purchase intent, it would be an obvious UI/UX enhancement to dynamically change the associated "search" button to reflect the predicted purchase action. The patent describes changing the "search" button to "Purchase iPhone 5S, 64 GB, Gold" based on user input and determined intent. This dynamic modification of a button's label and function based on real-time input and inferred context is a logical extension of known interactive UI design principles to streamline the execution of a highly probable action (like a one-click purchase). Similarly, offering post-purchase modification or cancellation options (as described in the patent) is a standard practice in e-commerce for managing orders and would be obvious to implement within such an integrated system.

In summary, the claims of US11468497 appear to be an obvious combination of known prior art concepts and widely understood technical principles. The motivation for a PHOSITA would be to improve user efficiency and experience by reducing clicks and cognitive load in online search and purchasing workflows, addressing shortcomings explicitly identified by the patent itself in existing systems.
