<http://press.redhat.com/2009/04/29/fighting-bad-patents-with-good-prior-art/> For a successful patent challenge, one must establish that the prior art contains all of the recitations in the claim. But a single prior-art reference need not contain exactly the claimed invention. Validity challenges often combine two or more prior-art references that together render the claimed invention obvious. It’s helpful for a challenger to collect a variety of prior art, because even though the individual pieces in isolation may be inadequate, the collection may establish invalidity. -- http://www.gutenberg.net - Fine literature digitally re-published http://www.plos.org - Public Library of Science http://www.creativecommons.org - Flexible copyright for creative work _______________________________________________ Ilug-cal-discuss mailing list [email protected] http://list.ilug-cal.org/mailman/listinfo/ilug-cal-discuss
