Fortinet has been ordered to stop selling antivirus in U.S. by the U.S. International Trade Commission after it emerged that there was a patent dispute with Trend Micro. A cease and desist order was issued on Monday against Fortinet after an initial decision by an ITC judge found that the antivirus capability in Fortinet's FortiGate integrated security products infringe on a Trend Micro patent. Seemingly, the patent covers virus scanning at a server before data is received by a client system. However, the ITC ruling only pertained to the antivirus functionality of the FortiGate platform, not its many other functions.
