Microsoft filed an application with the description of automatic Goodbye Messages to the US Patent Office via the Internet pager.
The idea of "invention" is that when communicating with an IM pager, a person often forgets to say goodbye at the end of a conversation. It looks ugly, and the other person may be offended. Therefore, the patented Microsoft program substitutes an automatic message, including taking into account the context. It may contain the name of the interlocutor or consist of one word “bye”.
