MPEP 800 primarily addresses which issue in patent applications?

MPEP 800 focuses primarily on the issues of double patenting and restrictions in patent applications. This section of the Manual discusses the principles related to the prohibition of obtaining multiple patents for the same invention (double patenting) and the importance of restricting claims in a single application to avoid claiming more than one invention, which could confuse the examination process or lead to an unjustifiable expansion of patent rights.

Double patenting can arise when two patents are issued for the same invention or for inventions that are obvious variants of one another, potentially leading to a monopolistic situation. This section ensures that applicants understand how to navigate these boundaries to maintain clarity in their claims and to adhere to patentability requirements within their applications.

The focus on restrictions addresses how a single application should contain claims that are directed to a single inventive concept. This is important for promoting efficiency in the examination process and ensuring that the claims made are justified and well-defined, helping examiners to evaluate them effectively.

In contrast, other options address different concepts: novelty and non-obviousness pertain to MPEP 2100, filing fees and procedures are handled in different sections like MPEP 500, and technical specifications of inventions are often discussed in the context of patentability standards, but
