U.S. Patent No. 6,599,545, issued July 29, 2003, is for the new and exciting invention of “Method for making a sandwich.”
To be patentable, an invention must be new, useful and nonobvious. Does this one qualify?
Because it’s such a technical subject, let’s first explore the “The Background Art” of the invention as described in the patent:
Sandwiches typically comprise two slices of bread, and a combination of sandwich fixings disposed between the bread slices.
That’s food for deep thought. Har har. Now that we understand the background art, let’s explore the invention itself, which is:
A method for inserting one foodstuff, such as sandwich fixings, into a second foodstuff, such as a bread bun, which includes forming a cavity in the second foodstuff.
Way over my head, but deconstructed, it appears that invention is: Drill a hole in a bun and jam some cold cuts in there.
