Prior Art In Barracuda-Trend Micro Lawsuit
Joe Barr writes "Bruce Byfield reports at Linux.com that a Swedish developer, Goran Fransson, has 'given a deposition in the Barracuda-Trend Micro case that appears to seriously undermine Trend Micro's patent on gateway virus scanning.' Gransson has resurrected a product (still in its shrinkwrap) sold by Ten Four, the company he worked for at the time, to prove that it provided gateway virus scanning in January 1995. Trend Micro's patent application was filed in September of that year. If you were — or worked for — a Ten Four customer during 1995, you might be able to help Barracuda prove that Trend Micro's patent omits prior art." We discussed this important patent case when it was filed in January. (Slashdot and Linux.com share a corporate overlord.)
That's not the way prior art works. Patents cover methods, not ideas. So a method that applies an old idea to a new situation can indeed be patentable. If you work for IBM, or some other company that has a bonus scheme for patent filing, one way to come up with shit to get patented is simply to make a list of all the new technologies out there and figure out how to apply old ideas using them.
How we know is more important than what we know.
