Intellectual Property India Publishes Patent Application for A Client-Side Mail-Add-In Method And System That Warns At Compose Time Upon Recipient Change, Via A Non-Blocking Compose Banner And Without Transmitting The Message To A Server, When A Current Recipient'S Domain Does Not Appear Among The Domains Of The Quoted Email Thread.

MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202641125225 A) filed by Teamwin Global Technologica Private Limited on October 21, 2026, for A Client-Side Mail-Add-In Method And System That Warns At Compose Time Upon Recipient Change, Via A Non-Blocking Compose Banner And Without Transmitting The Message To A Server, When A Current Recipient'S Domain Does Not Appear Among The Domains Of The Quoted Email Thread..

Inventor includes Mohan Kumar Siramdasu.

The application for the patent was published on October 30, 2026, under issue no. 44/2026.

Abstract: A CLIENT-SIDE MAIL-ADD-IN METHOD AND SYSTEM THAT WARNS AT COMPOSE TIME UPON RECIPIENT CHANGE, VIA A NON-BLOCKING COMPOSE BANNER AND WITHOUT TRANSMITTING THE MESSAGE TO A SERVER, WHEN A CURRENT RECIPIENT'S DOMAIN DOES NOT APPEAR AMONG THE DOMAINS OF THE QUOTED EMAIL THREAD. A mail-client add-in or extension is disclosed that, at compose time upon a recipient-change event (adding 0 ms of latency to message send) and entirely on the client, parses the quoted thread (historical) section of a message being composed for email addresses, reduces them to a set of thread domains, computes the set of current-recipient domains, and — when a current recipient's domain is absent from the thread-domain set — surfaces a non-blocking compose banner (InsightMessage infobar or inline top-of-compose banner) that names the new domain and the recipient. Dismissal or acknowledgment keyed to the message identifier and the new domain is recorded in client-side add-in storage so the banner does not re-nag, and removing the deviating recipient clears the banner (with optional two-click pre-send confirmation on hosts configured for send-time blocking). The check runs without transmitting the message, its body, or its recipient list to a server, converting a generic external-recipient notice into a conversation-specific "new domain" compose banner that catches autocomplete and look-alike domain errors. It is published defensively over expired prior art. Abstract figure: FIG. 2.
