You can simply add text right after the title page, there's no need for special commands …
\documentclass{book}
% just to have smaller pages:
\usepackage[papersize={10cm,14cm}]{geometry}
\begin{document}
% Titlepage
\title{My Book}
\author{I}
\maketitle
% copyright note
Don't steel my thoughts!
% First chapter (or TOC ...)
\chapter*{Preface}
This book is about how to wirte copyright notes
right after a title page \dots
% etc. ...
\end{document}
which will give a copyright page like this:

Note that theres no need for manual page breaking since \maketitle starts a new page after setting up the title page and \chapter start a new page by itself, too.
Now it’s time for some improvements:
- add some more information, like
\copyright\,2013, by me
- remove the page number with
\thispagestyle{empty}
- the effects of the following commands should be restricted to the copyright
page by adding a group, i.e. a pair of curly braces
{ ... }
- shift the information a bit lower with
\vspace*{4cm} or to the bottom of
the page with \vspace*{\fill} (the asterisk * in the command name is
necessary, because without it the space will be ignored at the beginning of
a page)
- set the indent to zero with
\setlength{\parindent}{0pt}
- set some space between paragraphs with
\setlength{\parskip}{\baselinskip}
(with that setting there will be an empty line between the paragraphs)
- make the font smaller with
\footnotesize and maybe italic with \itshape
Then we have the improved code
\documentclass{book}
% just to have smaller pages:
\usepackage[papersize={10cm,14cm}]{geometry}
\begin{document}
% Titlepage
\title{My Book}
\author{I}
\maketitle
% copyright note
{% begin group
\vspace*{65mm}
\thispagestyle{empty}
\footnotesize\itshape
\setlength{\parskip}{\baselineskip}
\setlength{\parindent}{0pt}
\copyright\,2013, by me
Don't steel my thoughts!
}% end group
% First chapter (or TOC ...)
\chapter*{Preface}
This book is about how to wirte copyright notes
right after a title page \dots
% etc. ...
\end{document}
resulting in a page like this:

I just wrote before the first chapter just by adding a new page (\newpage) and it worked well.
