Legal Definitions - undue-multiplicity-of-claims rejection

Definition: Undue-multiplicity-of-claims rejection is a type of rejection in patent law where a patent application is rejected because it makes an unreasonable number of claims.

Example: If a patent application has 100 claims, but only 10 of them are unique and the rest are variations of those 10, it may be rejected for undue-multiplicity-of-claims. This is because having too many claims can make it difficult for the patent examiner to determine the true scope of the invention.

This type of rejection is meant to encourage patent applicants to be concise and clear in their claims, and to avoid making unnecessary or redundant claims.
