EvilAlphonso notes news of a "Texas" IP holding company suing 36 actual companies for violating its claimed patent on spam filtering. Techdirt deconstructs the patent itself, No. 6,018,761, which seems to amount to little more than a database lookup. It was filed in 1996 and issued in 2000 (despite the lawyers' press release claiming that it "was awarded... nearly 15 years ago"). Among the companies being sued are 3Com, Apple, Google, AOL, Yahoo, J.C.Penney, IBM, Dell, Citigroup, and RIM. Not Comcast, Verizon, AT&T, or Microsoft, oddly enough.
