What is the impact of a defective priority or benefit claim?

A defective priority or benefit claim can have significant consequences for a patent application. According to MPEP 211.01, if the claim for priority or benefit is not properly made:

‘If the claim for priority or benefit is not included in an ADS, the claim for priority or benefit must be included in the first sentence(s) of the specification following the title or in an application data sheet. The specific reference to the prior application must be in the first sentence(s) of the specification following the title or in an application data sheet unless the reference appeared in a preliminary amendment filed on filing.’

The impacts of a defective claim can include:

  • Loss of priority date: This can affect the assessment of prior art against the application.
  • Potential rejection: Claims may be rejected if intervening prior art exists between the filing dates of the prior and current applications.
  • Inability to overcome certain rejections: Without the earlier priority date, it may be harder to overcome rejections based on intervening art.
  • Possible patent term reduction: If the defect is not corrected promptly, it could affect the patent term adjustment.

To avoid these issues, applicants should ensure that priority or benefit claims are properly made in accordance with 37 CFR 1.78 and correct any defects promptly using the procedures outlined in the MPEP.
