Abstract:
Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for receiving a first communication as part of a conversation, from an unauthenticated user of a web browser. A conversation identifier is determined based on the first communication. A first responder, a communication protocol, and a communication address of the first responder is determined. The first communication is sent to the first responder and a first reply is received. The conversation identifier is determined based on the first reply and the first reply is mapped to the web browser. The first reply is sent to the web browser.
Plain-Language Overview of Independent Claims
This patent essentially describes a "smart" chat routing system that acts as an intermediary, allowing an anonymous website user to connect with the right expert or agent without either party needing to know the other's contact information or use the same communication platform.
Independent Claim 1: Details a system for managing these communications. It begins when a user on a website, who is not logged in, starts a chat. An initial entity, the "first responder" (which could be an automated greeter or a virtual assistant), interacts with the user. Once the user sends a message, the system analyzes it to identify an appropriate "second responder" (a human expert, for example). The system then sends the user's message to this second responder using their preferred communication method (like SMS or email). When the second responder replies, the system uses a unique conversation ID to route the reply back to the correct anonymous user on the website.
Independent Claim 18: Describes the method or process performed by the system in Claim 1. It outlines the sequence of steps:
- Receiving a chat request from an unauthenticated user on a web page.
- Having a "first responder" send an initial message.
- Receiving the user's first message.
- Creating a unique ID for the conversation.
- Identifying a different, "second responder" based on the user's message.
- Determining how to contact the second responder.
- Sending the user's message to them.
- Receiving the second responder's reply.
- Using the conversation ID to link the reply back to the user.
- Sending the reply to the user's web browser.
