As noted by, among others, Eugene Volokh, a patent application has been filed with an obvious "test data" claim. The claim reads:

9. The method of providing user interface displays in an image forming apparatus which is really a bogus claim included amongst real claims, and which should be removed before filing; wherein the claim is included to determine if the inventor actually read the claims and the inventor should instruct the attorneys to remove the claim.

On the other hand, I have a lot of sympathy for the point made by "Tony2" in the comments, to the effect that the rendering of technical inventions into patents is the semantic equivalent of translating them into a foreign language spoken only by a specialized community. Bogus claims or not, I find as a technical person I can't make a lot of sense out of patent language. It's completely understandable that the inventor on this patent wouldn't be fluent in this foreign language and would trust that people paid hundreds of dollars per hour - the application-drafting lawyers - would in fact do their jobs.

So, yeah. Funny. And also kind of sad.
