The Federal Circuit sits in Washington, DC.

Section 102(b) of the patent statute establishes an "on-sale bar" for inventors who wait too long to apply for a patent.  The bar — a species of patent invalidity — kills a patent whose inventor "applies for a patent more than one year after making an attempt to profit from his invention by putting it on sale."  Atlanta Attachment Co. v. Leggett & Platt, Inc., No. 07-1188, slip op. at 5 (Fed. Cir. Feb. 21, 2008).

The Federal Circuit appears to have decided as a matter of law that the on-sale bar invalidated one of the claims in the patent-in-suit and remanded for consideration of other challenges to different claims in the patent or to the patent as a whole.

Blawgletter loves saying "bar bars".  Also BarBar.
