USPTO Orders Reexam of Trend Micro's AntiVirus Patent Based on Prior Art

By Pamela Jones et al.

Once again, your prior art searching on Groklaw proved useful.

The USPTO on September 16 issued an order granting Fortinet's petition to reexamine the validity of the Trend Micro patent on antivirus functionality, the 5,623,600 patent, on the grounds that a "substantial new question of patentability" exists based on prior art now being considered. Fortinet publicly acknowledges the help of the open source community, specifically mentioning the prior art searching you guys did here on Groklaw in June. The ultimate outcome is yet to be determined, of course, and that's in the hands of the lawyers now, but you guys did your part. It's a great partnership, techies and lawyers, and I thank you for working hard on this, and I hope it leads to a just resolution.
