2. Provisional vs. Non Provisional
Drawings are the foundation of any patent application, whether it is a
provisional or non provisional application. Therefore, it is imperative to abide
by the guidelines of the United States Patent and Trademark Office (USPTO)
to ensure that the drawings are clear and the patent passes examination.
To understanding the differences between the two drawing approaches, we first
need to know what provisional and non-provisional patent applications are.
Provisional patent application basics:
• Provisional patent applications require a low USPTO filing fee
and are less expensive than the regular non provisional patent
applications.
• Provisional patent applications last only for 12 months. You still
have to file a non provisional patent application within 12 months
of your provisional application in order to retain the advantage of
the provisional’s filing date. This is just like filing an extension on
your tax return; you still need to pay the taxes and file real tax returns.
• Claims are not required for a provisional patent application.
• Provisional applications are not examined. A follow-on non
provisional goes to the back of the examination line. So if you are
racing against time and want your patent issued quickly,
a provisional application is not ideal.
To be successful, any provisional application must include thorough details
of the invention, just as in a non provisional application.
Non provisional patent application basics:
• A non provisional application establishes the filing date of your
patent application and begins the examination process by the USPTO.
• Non provisional applications are comprised of a specification
(description and claims), an oath or declaration, a drawing (when
necessary), and a fee.

3. Provisional vs. Non Provisional
Patent illustration drawings are critical and can determine the
success of any patent application. Therefore, it is important that
all drawings are in accordance with USPTO rules.
By law, all patent applicants are required to provide a draw-
ing of the invention if it increases the understanding of the
invention. Exceptions may include for matter compositions or
processes where drawings are irrelevant for comprehension.
The drawings also differ depending on the type of
patent application.
• Most drawings for a provisional application are drawn
by the inventor or an attorney, and are usually rendered
in an unsophisticated manner.
• Provisional drawings can be photographs, hand
drawings, CAD drawings, or clean line art with hand-
drawn numbers and leader lines.
• A typical provisional artwork will have the inventor’s
signature on it to prove the date of the invention.
• Non provisional drawings are usually drawn by an
illustrator and filed with an application usually written
by a patent attorney.
• Non provisional drawings must detail every attribute
of the invention specified in the claims. The drawings
must adhere to the USPTO’s specifications including
paper size, paper type, margin widths, and other details.
These explicit details are for overall uniformity when
the patent is issued and published.
• According to the USPTO, no names or labels are
permitted near the drawing. Applicants are expected
to use the space in the top margin to identify each
sheet of drawings. This identification may consist of the
attorney’s name, docket number, the inventor’s name,
application number, and/or page numbers.
