Trend Micro says it is defending its turf, but Barracuda Networks is casting the situation as an attack on open-source software.
Barracuda Networks is going on the attack in response to security vendor
Trend Micro's assertion that it violated one of Trend Micro's patents.
At the center of the controversy is a Trend Micro patent the company says
covers virus scanning of a server, such as a gateway or appliance, before
data is received by a client computer. But while Trend Micro officials say they
are only defending their turf, Barracuda Networks
casting the situation as an attack on open-source software.
of Barracuda, claims his company
is being attacked for its use of ClamAV, an open-source network anti-virus
project purchased last year by Sourcefire. After Trend Micro officials sent
Barracuda letters about the matter in late 2006, Barracuda decided to take the
federal court and filed for a declarative judgment to settle the matter. Then,
in December, Trend Micro countered by filing a complaint with the U.S.
International Trade Commission.
"In their ITC filing they accused us of importing the ClamAV software and
that [that] is infringing software. ... In the federal case, their claim is that
we manufacture [and] sell a product that infringes on their patent," Drako
said. "In their explanation ... they specifically refer to ClamAV as the source
of the infringement, and call out the subroutines-they actually went through
the source code of ClamAv and found the specific subroutines which they claim
infringe on their patent."
