Patent applications can be directed to three broad types of subject matter:
- (A) applications for patents as provided for by 35 U.S.C. 101 relating to a “new and useful process, machine, manufacture, or composition of matter,” etc.;
- (B) applications for plant patents as provided for by 35 U.S.C. 161; and
- (C) applications for design patents as provided for by 35 U.S.C. 171.
The first type of patent application is sometimes referred to as a “utility” patent applications when being contrasted with a plant or design patent application. The specialized procedure which pertains to the examination of applications for design and plant patents are treated in detail in Chapters 1500 and 1600, respectively.
