Trend Micro is suing Barracuda because the latter supposedly infringes on a patent the former owns regarding the implementation of a anti-virus through an SMTP and FTP gateway. Apparently, Trend Micro is threatened by the less expensive solution of Barracuda which involves off-the-shelf hardware components and the open source Clam Anti-Virus. And so, instead of lowering its cost or improving its own features and services, it decides to sue on the grounds of its stupid patent. It only goes to show that they’re not really concerned about the security of computer users but only on their own profit. That’s just lame.
