Trend Micro's patent case against Barracuda Networks' use of ClamAV has drawn an apparent boycott.

A group calling itself the "Dutch free knowledge and culture advocacy group ScriptumLibre" wants a worldwide boycott on Trend Micro products. ScriptumLibre said that Trend Micro's actions were 'well beyond the borders of decency.' It suggests a series of actions that people can take in the boycott.

Trend Micro claims that its patent case against Barracuda Networks isn't about free software. The case is an attempt to enforce Trend Micro's patent for antivirus detection on an SMTP or FTP gateway. Already successfully used against such companies as McAfee, Symantec, and Fortinet, the patent is being applied against Barracuda for its distribution of the open source Clam Antivirus (ClamAV).

Trend Micro has also filed with the American International Trade Commission in November 2007 in a bid to stop it being imported from outside the United States.
