Patent holding company NTP has filed a lawsuit against
Palm, alleging
that the maker of the
Treo smartphone
infringes on the company's patents.
NTP is a holding company that attempts to collect licence fees for a set of
patents covering a wireless email system.
The company is best known for its
five-year
legal battle with
BlackBerry maker
Research
In Motion.
RIM settled the case in March with a payment of $612.5m after facing an
injunction that would have shut down the service in North America.
NTP also has licence agreements with
Nokia,
Good and
Visto.
The
US
Patent and Trademark Office is in the process of re-examining two of the NTP
patents and issued final rejection notices earlier this year.
NTP is demanding damages as well as an injunction that bars Palm selling and
servicing the products that infringe on its patents.
But the case against Palm could be a much more difficult fight following a
ruling by the US Supreme Court in May imposing
restrictions on
injunctions in patent cases.
The new rules effectively prevent patent holding companies from using
injunctions to bully manufacturers into purchasing a licence for their
technology.
