The purpose of making rejections in patent examination is to ensure that only valid and novel inventions receive patent protection. According to MPEP 706:
‘After a thorough study of the application, the examiner reaches a conclusion as to whether the claims are patentable. If the examiner concludes that the claims are not patentable, the claims will be rejected.’
Rejections serve several important purposes:
- To uphold the standards of patentability set forth in 35 U.S.C.
- To provide applicants with a clear understanding of why their claims are not patentable
- To give applicants an opportunity to amend their claims or provide evidence of patentability
- To ensure that the patent system promotes innovation by granting exclusive rights only to truly novel and non-obvious inventions
By making well-reasoned rejections, examiners contribute to the integrity of the patent system and help maintain the balance between rewarding innovation and preserving the public domain.
