I'm about to file a USPTO provisional patent in a couple of weeks.

Is there any upper limit for the number of drawings I can have in my utility patent?

  • What numbers are you thinking of? I can't find anything, but I'm almost sure there is nothing and you can have as many as you want. I've seen patents with dozens of images, but more than ~10 are normally not needed. – DonQuiKong Apr 5 '17 at 11:52
  • @DonQuiKong I have around 15 images. – Giri Apr 5 '17 at 12:22
  • i dont think that there is upper limit. i can't even find anything as DonQuiKong mentioned. @DonQuiKong Is there any additional fee for extra sheets or each drawing? – ASHU VERMA Apr 5 '17 at 12:32
  • @ASHUVERMA Can you link me to the fee page? I have been told micro entity patent fee is $65 for the first 5 patents – Giri Apr 5 '17 at 12:35
  • $65 is the Provisional application filing fee as 37 CFR 1.16(d). i think DonQuiKong can add little more on this. – ASHU VERMA Apr 5 '17 at 12:38

The USPTO imposes an additional fee beyond the provisional filing fee for each 50 sheets beyond 100 sheets (pages) for a provisional patent application. That fee ranges from $100 for a micro entity, $200 for a small entity and $400 for a large entity. The limit is based on the number of total sheets(pages) in the application, including the drawings and specification. Other than this additional fee, there is no limitation on the number of drawings. There is a similar fee structure for when a utility application is filed based on the provisional application.

Other jurisdictions may have other fee structures for the size of the application.

  • I like answers which link to official documentation so bravo. You should perhaps use the linking tool which makes it easier to hide long web addresses. – Eric S Sep 8 at 18:12
  • HI Eric, you may like only official links but some time official information language is too legal which will not help inventors in better understanding. blogs like our invention-patent-drawings.com/patent-drawings-blog will try to simplify the information in terms of language and information. – Tara Reddy Sep 12 at 5:09
  • I find the official links readable. Links to commercial content, especially firms affiliated to the poster, are considered spammy on Stack Exchange and are to be avoided. There are exceptions such as interpretations of court decisions where official guidance isn’t available. Wikipedia articles are usually okay and preferred to commercial blogs. – Eric S Sep 12 at 12:17
