What is the significance of WIPO Standard ST.26 in the MPEP’s definition of nucleotides?
The MPEP 2412.03(d) explicitly references WIPO Standard ST.26 in its definition of nucleotides:
“‘Nucleotide’ includes any nucleotide, nucleotide analog, or modified nucleotide as defined in paragraphs 3(f) and 3(g) of WIPO Standard ST.26.”
WIPO Standard ST.26 is an international standard for the presentation of nucleotide and amino acid sequence listings in patent applications. Its incorporation into the MPEP definition serves several purposes:
- Harmonization with international patent practices
- Standardization of nucleotide definitions across patent offices
- Inclusion of a wide range of nucleotide structures, including modified and synthetic forms
By referencing WIPO Standard ST.26, the MPEP ensures that patent applications filed in the United States are consistent with international standards for sequence disclosures. This is particularly important for applicants seeking patent protection in multiple jurisdictions.
