A Little Background on Columbus

First, a little background on Backgrounds. 37 CFR 1.77(b)(7) suggests that an application should contain a “background of the invention.” However the MPEP is ambiguous as to its content:

Experienced practitioners know that the Background is just another opportunity to make a mistake. From calling it a “BACKGROUND OF THE INVENTION” rather than simply “BACKGROUND,” to admitting admitting prior art that is not prior art, or otherwise limiting the scope of the claims, ther seems little to be gained and much to be lost with a carelessly drafted background. While patent applications continue to include Backgrounds, they are getting shorter and less detailed.

An interesting example of an old-school background, particularly apropos on Columbus Day, is the Background in U.S. Patent No. 5,802,513:

The drafter probably should have stopped right here, and today probably would have stopped right here. A hint about the subject matter of the invention, and the problems it addresses, without admitting anything in particulary is prior are, and without saying anything that might otherwise limit the scope of the claims.
