AFAIK, at USPTO, there are requirements on font size and format for non provisional application. Is there any requirement applying to provisional application?
Because I want to combine many unrelated inventions into a single provisional patent, and they limit it to 100 pages (or additional fee is added). So I will try to squeeze text size and format to increase text per page. I think since I will file electronically, the info will not lose, so I will write as small as possible (unlike filing in paper where small text can lose information)
