Patent law, rather than copyright, is more often used to protect a file format. Although patents for file formats are not directly permitted under US law, some formats encode data using patented algorithms.
Size and Format Common sizes include 8.5″ x 11″ or A4 paper size, with a recommended margin of at least one inch on all sides. Digital drawings must meet the file format and resolution specifications provided by the patent office.
Utility : Patent numbers consist of six, seven or eight digits. Enter the Patent number excluding commas and spaces and omit leading zeroes. Reissue : (e.g., Rennnnnn, RE000126) must enter leading zeroes between "RE" and number to create 6 digits.
