In 1996, the Commissioner of Patents and Trademarks decided sua sponte to partially waive the requirements of 37 CFR 1.141 et seq. and permit a reasonable number of such nucleotide sequences to be claimed in a single application. See Examination of Patent Applications Containing Nucleotide Sequences, 1192 OG 68 (November 19, 1996).

In 2007, the Commissioner for Patents rescinded the waiver. See Examination of Patent Applications Containing Nucleotide Sequences, 1316 OG 123 (March 27, 2007). All pending applications are subject to the 2007 OG notice. Note, however, that supplemental restriction requirements will not be advanced in applications that have already received an action on their merits for multiple nucleotide sequences in the absence of extenuating circumstances. For national applications filed under 35 U.S.C. 111(a), polynucleotide inventions will be considered for restriction, rejoinder, and examination practice in accordance with the standards set forth in MPEP Chapter 800. Claims to polynucleotide molecules will be considered for independence, relatedness, distinction and burden in the same manner as claims to any other type of molecule.

Polynucleotide molecules defined by their nucleic acid sequence (hereinafter “nucleotide sequences”) that encode different proteins are structurally distinct chemical compounds. These sequences are thus deemed to normally constitute independent and distinct inventions within the meaning of 35 U.S.C. 121. Absent evidence to the contrary, each such nucleotide sequence is presumed to represent an independent and distinct invention, subject to a restriction requirement pursuant to 35 U.S.C. 121 and 37 CFR 1.141 et seq.
