Adobe Acrobat 7 Professional - Manual (Page 308)

Exporting comments to a Word document (Windows)
In some instances, reviewers make comments in an Adobe PDF document that was
created from a Microsoft Word document. If you need to make changes to the original
Word document based on these comments, it may be easier for you to import the
comments directly into the Word document, rather than switch back and forth between
Word and Acrobat. You can use Acrobat or Word to export comments from the PDF
document into Word, and you can import comments in Word 2002 and later. The PDF
document must be created in Word and include tags.
