Three URLs for Researching Patents
Linda and others,
I used these three URLS to search for patent information last year.
Recent patents often provide patent histories.
Glass On-line Patents
<http://www.glassonline.com/>
IBM
Ęs Intellectual Property Newtwork, 1971 to present
<http://www.patents.ibm.com/ibm.html>
US Patent and Trademark Office
<http://www.uspto.gov/patft/>
Perhaps someone can add to this list for all of us.
Best regards, Roc
