Patent number: 11494739Abstract: Message display control means updates and displays messages sequentially on a message list screen each time message receiving means receives a message. When input detection means detects a response message, identification means identifies the latest message at the time of detection and the response message. Response message sending means sends the response message as a response to the identified message to other participants upon completion of input of the response message. Therefore, even in the case where the message list screen is updated due to receiving the subsequent message during the input of the response message, the completed response message is able to be sent back to the response object message.Type: GrantFiled: June 17, 2021Date of Patent: November 8, 2022Assignee: Airbnb, Inc.Inventors: Nobuyuki Ishikawa, Kazuhiro Konno, Akira Saitoh, Shigeki Takeuchi, Hayato Uenohara
