  <p><strong>Sony Reader</strong> provides <code>.note</code> files. These are just wrapped <code>.svg</code> files (<a href="http://en.wikipedia.org/wiki/Scalable_Vector_Graphics" rel="noreferrer">scalable vector graphics</a>, an XML based image format). I believe this is because the Sony Reader notes can be annotations, doodles via a stylus and text highlights. You can find out more information about extracting them <a href="http://www.sonyreaderboards.com/forums/viewtopic.php?p=12762" rel="noreferrer">here</a>.</p>
  
  <p><strong>Kobo</strong>, according to <a href="http://www.mobileread.com/forums/archive/index.php/t-193916.html" rel="noreferrer">this thread</a>, stores annotations in <code>[epub-filename].annot</code>, which is a standard XML file. I'm not sure if this differs for other eBook formats.</p>
  
  <p>You get the point. There is no single standard format or way to handle annotations. That being said, perhaps someone could take various open source tools and create a single utility for exporting and/or importing annotations to various devices (sounds like an interesting side project...).</p>

  The short answer, no.
  
  **Kindle** uses what is called a `My Clippings.txt` file using standard text formatted in a particular way. Here is an example that was taken from [this readme file](https://github.com/mrajcok/kindle_clippings/blob/master/README) on a GitHub project (modified slightly to remove leading comment characters).
