FAQs Patent Questions

Question:Patent application drawings must be drawn on specified standard sized paper.

Answer:
Yes. The Office specifies the size of the sheet on which the drawing is made, the type of paper, the margins, and other details relating to the making of the drawing. The reason for specifying the standards in detail is that the drawings are printed and published in a uniform style when the patent issues, and the drawings must also be such that they can be readily understood by persons using the patent descriptions.

Question:A patent claim listing is required for preliminary amendments present on the filing date.

Answer:
Yes, a claim listing of every claim ever presented in the application is required, even for preliminary amendments present on the filing date of the application. The status identifier, (new), instead of (original), should be used for claims added by a preliminary amendment, even when the preliminary amendment is present on the filing date of the application and the first executed oath or declaration refers to the preliminary amendment.

Question:Utility patents protects the way an article is used and works and a design patent protects the way an article looks.

Answer:
A “utility patent” protects the way an article is used and works (35 U.S.C. 101), while a "design patent" protects the way an article looks (35 U.S.C. 171). Both design and utility patents may be obtained on an article if invention resides both in its utility and ornamental appearance.
