The next section of the specification is the brief summary of the invention. This is a brief summary or general statement of the invention. The summary is separate and distinct from the abstract and is directed toward the invention rather than the disclosure as a whole. The summary may point out the advantages of the invention or how it solves problems previously existent in the prior art (and preferably indicated in the background of the invention).

In chemical cases it should point out, in general terms, the utility of the invention. If possible, the nature and gist of the invention or the inventive concept should be set forth. Objects of the invention should be treated briefly and only to the extent that they contribute to an understanding of the invention.

The next section of the specification is a brief description of the drawing(s). The description is a reference to and brief description of the drawing(s).

This is followed by a detailed description of the invention. This is a description of the preferred embodiment(s) of the invention. The description should be as short and specific as is necessary to describe the invention adequately and accurately.

Where elements or groups of elements, compounds and processes, which are conventional and generally widely known in the field of the invention are described, and their exact nature or type is not necessary for an understanding and use of the invention by a person skilled in the art, they should not be described in detail. However, where particularly complicated subject matter is involved or where the elements, compounds or processes may not be commonly or widely known in the field, the specification should refer to another patent or readily available publications that adequately describe the subject matter.

The next section of the specification is the claims. As indicated in the previous blog entry, the claims are the most important part of the patent application and are treated, commonly, like a separate part of the patent application. The claims define the metes and boundaries of the property right claimed in the invention. The claims are analogous to a description of the property line in a real-estate deed. The claims will be discussed in detail in later blog entries.

The next section of the specification is the abstract. An abstract is a brief narrative of the disclosure as a whole in a single paragraph of 150 words or less commencing on a separate sheet following the claims.

The final section of a specification is the sequence listing for certain biological inventions. The requirement for a sequence listing applies to all sequences disclosed in a given application, whether the sequences are claimed or not.
