What is the significance of avoiding ‘undue multiplication of references’ in patent examination?
The concept of avoiding ‘undue multiplication of references’ in patent examination is mentioned in MPEP 707.07(g). The MPEP states:
“The examiner ordinarily should reject each claim on all valid grounds available, avoiding, however, undue multiplication of references.”
This guideline is significant because it aims to balance thoroughness with efficiency in patent examination. It means that examiners should:
- Provide comprehensive rejections covering all valid grounds
- Use a reasonable number of references to support rejections
- Avoid excessive citation that could obscure the main reasons for rejection
- Focus on the most relevant and strongest prior art references
By avoiding undue multiplication of references, examiners can provide clear, focused rejections that applicants can more easily understand and respond to, promoting more efficient patent prosecution.
