IEEEtran: how to add copyright footer at the center of bottom with multiple lines

Question

I have a journal paper that requires me to enter the copyright footer. The solution here partially solved my problem.

However, the content of the footer is

Copyright~\copyright~2017 IEEE. Personal use of this material is permitted. However, permission to use this material for any other purposes must be obtained from the IEEE by sending a request to [email protected].

which is too long to fit in one line. I tried to use line break \\ or \newline, it doesn't work. What is the correct method to break the copyright footer into multiple lines in IEEEtran? Thanks.

Answer 1

I have figured it out. The way to do is to use a minipage for the copyright content. One example is as follows:

\makeatletter
\def\ps@IEEEtitlepagestyle{
  \def\@oddfoot{\mycopyrightnotice}
  \def\@evenfoot{}
}
\def\mycopyrightnotice{
  {\footnotesize
  \begin{minipage}{\textwidth}
  \centering
  Copyright~\copyright~2017 IEEE. Personal use of this material is permitted. However, permission to use this  \\ 
  material for any other purposes must be obtained from the IEEE by sending a request to [email protected].
  \end{minipage}
  }
}
