Can an examiner withdraw the election of species requirement in a Markush claim?

Yes, an examiner can withdraw the election of species requirement in a Markush claim under certain circumstances. According to MPEP 803.02:

“If on examination the examiner finds that the elected species is allowable and determines that all claims to species are allowable, the restriction requirement between the elected species and the non-elected species should be withdrawn.”

This means that if the examiner determines that:

  • The elected species is allowable
  • All claims to species are allowable
  • The search and examination can be made without serious burden

Then the examiner should withdraw the election of species requirement and examine all species.
