Now, MercuryNews is speculating that Google may buy Olive Software. I don't know if the deal will ever happen but surely, Olive does make sense for Google.
Google is in the process of scanning millions of books, catalogs for Google Print and Google Catalogs using their proprietory scanning software. (Google doesn't use Acrobat, I confirmed this with the Adobe team). An established proved OCR technology like Olive could help Google concentrate their workforce on other areas like Search.
