When is a Restriction Requirement typically issued by an examiner?

A Restriction Requirement is typically issued by an examiner when there are multiple species claimed in a patent application. Under patent law, an applicant can claim multiple embodiments or variations of their invention, known as "species." However, the patent office requires that an applicant elect a single species to prosecute at a time when there are distinct and separate inventions that are claimed. This is because the claims must clearly define the invention and ensure that each invention is adequately examined, preventing confusion and maintaining a manageable examination process.

While multiple independent claims can also lead to a Restriction Requirement in some cases, the primary basis for issuing one is to handle claims that embody different inventions, which necessitates an applicant choosing one for further prosecution. This focuses the examination on a single invention, allowing for a more thorough review of that particular aspect.

In contrast, options regarding claims that are too broad or generic, or those that do not meet filing requirements, pertain to issues of clarity and compliance rather than the central doctrine of distinct inventions that governs the issuance of a Restriction Requirement. Thus, the essence of the correct answer lies in the relationship between the claims of the application and the patent office's need to manage distinct inventions effectively.
