Some quotes:
"A Washington district court this week denied a request for a preliminary
injunction by Mailblocks, an antispam software company that claims rival
Spam Arrest is violating its patented technology. "
"The court ruled in favor of Spam Arrest's motion to stay the request
despite its admission of patent infringement. Spam Arrest argued instead
that Mailblocks' patents were invalid because of "prior art"--that is,
because systems for challenge-response technology predate Mailblocks' own.
The company also requested that similar pending patent complaints by
Mailblocks, such as one against EarthLink, should be combined and heard as
one by the Multidistrict Litigation Panel, which specializes in hearing
multiple complaints. "
" The company has already dropped a similar suit against MailFrontier
because it entered into discussions, he said. Also, the company expects to
announce its first licensing partner later this week"
