These are the numbered paragraphs at the end of the patent. The claims define the subject matter that defines the invention. Put another way, the claims define the “metes and bounds” of property protected by the patent.
There are two basic types of claims – independent and dependent. Independent claims are standalone claims and do not refer to any other claims. Dependent claims refer to another claim. A dependent claim requires all the features explicitly recited in the dependent claim plus all the features recited in the claim(s) from which the dependent claim depends. Therefore, a dependent claim is said to be “narrower” than a claim from which it depends.
In this patent, claim 1 is an independent claim because it does not refer to any other claims. Claim 4, for example, is a dependent claim because it refers to claim 1. Thus, claim 4 requires the features explicitly recited in claim 4 plus the features recited in claim 1.
There are several different ways an inventor can claim her invention, including, for example, claiming the invention as an apparatus, a device, an article of manufacture (an object), a composition of matter, or a method. Typically, the first few words of a given claim tell you which way the inventor is using the claim to define her invention.
In this patent, claim 1 is an article of manufacture (an object), specifically “a Halloween treat carrier.” Claim 16 is a method claim, in particular “a method of decorating a pumpkin.”
