Seer Systems, Inc. and Stanley Jungleib have issued a written litigation threat to EFF over statements made as part of EFF's Patent Busting Project. EFF responded today, noting that its discussions of Seer and Jungleib were protected by the First Amendment. Both letters are attached below.

The letter arrived in the wake of the Patent and Trademark Office granting EFF's Request for Ex Parte Reexamination a Seer Systems patent on December 31, 2008. EFF had filed for a reexamination of Seer Systems' Patent No. 5,886,274 in October 2008, and the PTO found that the reexamination request raised "a substantial new question of patentability." We'll let you know what happens next.
