How to add copyright notice (in a box with borders) at bottom of first page?

For IEEE conference format, you ca use:

\IEEEoverridecommandlockouts
\IEEEpubid{\makebox[\columnwidth]{978-1-4799-2442-4/13/\$31.00 \copyright 2013 IEEE \hfill} \hspace{\columnsep}\makebox[\columnwidth]{ }}

just after:

\begin{document}

You can find some more practical information in this blog post, and in the original IEEEtran class howto.

You can do this in several ways; for example you can use the textpos, or the atbegshi package, or TikZ. Here's an example using TikZ:

\documentclass{IEEEtran}
\usepackage{tikz}
\usepackage{lipsum}

\newcommand\copyrighttext{%
  \footnotesize text text text text text text text text text text text text
   text text text text text text text text text text text text text text text text
   text text text text text text text text text text text text text text text text
   text text}
\newcommand\copyrightnotice{%
\begin{tikzpicture}[remember picture,overlay]
\node[anchor=south,yshift=10pt] at (current page.south) {\fbox{\parbox{\dimexpr\textwidth-\fboxsep-\fboxrule\relax}{\copyrighttext}}};
\end{tikzpicture}%
}

\begin{document}

\copyrightnotice
\lipsum[1-10]

\end{document}

I've been googling some more, and bumped into the package textpos, which gave me a workable solution (don't know if it is the 'best' one). It requires me to tweak the position and width of the box, but that's okay.

\documentclass{IEEEtran}
\usepackage[absolute,showboxes]{textpos}

%set unit to be pagewidth and height, and increase inner margin of box
\setlength{\TPHorizModule}{\paperwidth}\setlength{\TPVertModule}{\paperheight}
\TPMargin{5pt}

%define \copyrightstatement command for easier use
\newcommand{\copyrightstatement}{
    \begin{textblock}{0.84}(0.08,0.93)    % tweak here: {box width}(leftposition, rightposition)
         \noindent
         \footnotesize
         \copyright  IEEE, 2012. Blablablablabla ... more text goes here
    \end{textblock}
}


\begin{document}
     \copyrightstatement
     \title{Title of my paper}
     and all the rest...
\end{document}
