I will try to file a test patent, basically a null patent for familiarizing with the filing process without spending any money. Is there any legal issue with this?
The Manual for Patent Examination (MPEP) has some sections that mention that anything submitted "is not being presented for any improper purpose, such as to harass, cause unnecessary delay, . . ". A famous not really an application is "Method and instrument for proposing marriage to an individual" US 20070078663 A1 . I wouldn't file anything that seemed to be signed.
