Re: HP calc patents (list) Message #2 Posted by Peter Monta on 23 July 2004, 3:35 a.m., in response to message #1 by Klaus Thanks for the list. There's also an open-source tool, pat2pdf, to obtain patent PDFs: http://www.tothink.com/pat2pdf/ One can comment out the line that removes the raw TIFF images, too, so patent pages can be fed to OCR tools. Cheers, Peter Monta
