Patent No. US10841253 (titled "Two-way real time communication system that allows asymmetric participation in conversations across multiple electronic platforms") on Feb 8, 2018. The application was issued on Nov 17, 2020.
’253 is related to the field of real-time communication (RTC) and cross-protocol message routing. Traditionally, instant messaging, SMS, and email operate in silos, requiring both participants to use the same software or protocol and know each other’s contact details beforehand. This patent addresses the technical challenge of bridging these disparate communication channels to allow anonymous, topic-based interactions between users on different platforms.
The underlying idea behind ’253 is the use of a centralized proxy server that acts as a protocol-agnostic bridge, decoupling the initiator’s interface from the responder’s preferred communication channel. By assigning a unique conversation identifier to a topic-based request, the system can route messages across different formats—such as converting a web-based chat into an SMS or an instant message—while maintaining a continuous dialogue thread. This allows for a protocol-independent handshake where the system matches participants based on expertise or criteria rather than pre-existing contact lists.
The claims of ’253 focus on a system and method that routes a conversation request from an initiator to a set of responders selected based on the topic and the initiator's past communication history. The independent claims specifically require the system to send the initiator's prior conversation history to the selected responder to provide context. Furthermore, the claims cover the specific technical capability of a responder to switch their active communication channel mid-stream, such as moving from an email response to an SMS response, while the system continues to map these disparate inputs to the same original conversation.
In practice, the invention functions as an intelligent switchboard that preserves anonymity by stripping identifying metadata from the message packets. When an initiator asks a question on a website, the server identifies available experts and pushes the query to them via their registered preferences, such as a mobile phone number. The system uses the conversation identifier to ensure that when a responder replies via SMS, the text is correctly injected back into the initiator’s web-based chat window, creating a seamless user experience despite the underlying protocol mismatch.
This approach differs from prior solutions by eliminating the requirement for a shared communication client and by utilizing asymmetric session management. Unlike standard chat rooms or email threads, the responder can dynamically change their device or protocol during a single session without breaking the connection. By integrating the initiator's historical data into the routing logic, the system ensures that the responder is equipped with relevant background, moving beyond simple message forwarding to a context-aware cross-platform gateway.
In the early 2010s when ’253 was filed, real-time communication systems were typically implemented using siloed architectures where both the initiator and the responder were required to utilize identical protocols and software clients to establish a session. At a time when digital messaging commonly relied on the manual exchange of specific destination addresses or unique identifiers to route data, cross-platform interoperability was limited by the lack of centralized translation layers capable of bridging disparate transport layers like SMS, instant messaging, and email. Hardware and software constraints made the dynamic routing of anonymous, topic-based requests non-trivial, as session persistence and message mapping generally depended on static, pre-defined peer-to-peer connections rather than mediated, asymmetric discovery mechanisms.
The disclosed invention represents a technical advancement in communication session management through the integration of a centralized mapping architecture that decouples the initiator’s communication mode from the responder’s communication mode. By utilizing a conversation identifier to bridge disparate protocols, the system enables an architectural shift from address-based messaging to topic-based discovery, allowing initiators to broadcast requests without prior knowledge of responder identities or specific destination addresses. This configuration overcomes the technical constraint of protocol dependency by dynamically routing responses from multiple, heterogeneous communication channels back into a unified interface for the initiator. Furthermore, the system enables asymmetric conversation management, providing a technical mechanism to maintain initiator anonymity while concurrently managing isolated sub-sessions between the initiator and multiple responders across different network environments.
The patent includes a total of 20 claims, with claims 1, 14, and 18 serving as the independent claims. These independent claims focus on a real-time communication system, a computer-readable medium, and a method for managing conversations by selecting responders based on criteria and past communications, mapping responses across different communication modes using unique identifiers, and facilitating the transition between multiple real-time messaging formats. The dependent claims serve to specify additional features such as maintaining participant anonymity, utilizing SMS as a communication mode, filtering or routing responses from multiple responders, removing identifying information from messages, and managing active communication modes based on responder activity.
