The plaintiffs in Eldred v. Ashcroft (formerly Eldred v. Reno) have petitioned the D.C. Circuit Court of Appeals for rehearing en banc. The petition can be found here.. (A pdf version is here.) I especially like the opening line:

"The Framers of our Constitution imposed only one real obligation on Congress with respect to what we now call "intellectual property":  that there shall be, at the federal level, a public domain supported by creative works."
