What is the purpose of an acceptable depository for biological materials?

An acceptable depository for biological materials serves a crucial purpose in the patent application process for biotechnology inventions. According to MPEP 2405: “The purpose of a deposit is to supplement the written disclosure in an application where the invention involves biological material and words alone cannot sufficiently describe how to make and use the invention…

What is pre-AIA 35 U.S.C. 103(b) and when does it apply?

Pre-AIA 35 U.S.C. 103(b) is a provision applicable to biotechnological processes. It precludes a rejection of process claims which involve the use or making of certain nonobvious biotechnological compositions of matter under pre-AIA 35 U.S.C. 103(a). This provision is only applicable to applications subject to pre-AIA 35 U.S.C. 102. As stated in the MPEP: Only…

What is the status of peptide nucleic acid (PNA) residues in amino acid sequence listings?

According to MPEP 2412.03(b), peptide nucleic acid (PNA) residues have a special status in amino acid sequence listings. The MPEP clearly states: “A peptide nucleic acid (PNA) residue is not considered an amino acid, but is considered a nucleotide.” This distinction is important for patent applicants and examiners because: PNA residues should not be included…

How do the sequence rules apply to nucleotide sequences in patent applications?

How do the sequence rules apply to nucleotide sequences in patent applications? The sequence rules for nucleotide sequences in patent applications have specific requirements as outlined in MPEP 2412.01: “The rules require disclosure of nucleotide and/or amino acid sequences […] if a sequence is disclosed in a patent application by enumeration of its residues and…

What are the formatting requirements for nucleotide sequences in a Sequence Listing?

Nucleotide sequences in a Sequence Listing must adhere to specific formatting requirements: Only single strands may be depicted. Strands should be shown in the 5′ to 3′ direction from left to right. The single-stranded nucleotide may represent a strand of a linear or circular, single or double-stranded sequence. As stated in the MPEP: On nucleotide…

What is the definition of “nucleotide” according to the MPEP?

According to MPEP 2412.03(d), a “nucleotide” is defined as follows: “‘Nucleotide’ includes any nucleotide, nucleotide analog, or modified nucleotide as defined in paragraphs 3(f) and 3(g) of WIPO Standard ST.26.” This definition encompasses a wide range of nucleotide structures, including both natural and modified forms. The MPEP further elaborates that a nucleotide contains: A specific…

What types of backbone moieties are included in the MPEP’s definition of a nucleotide?

The MPEP 2412.03(d) provides a comprehensive list of backbone moieties that can be part of a nucleotide. These include: 2′ deoxyribose 5′ monophosphate (found in deoxyribonucleotides) Ribose 5′ monophosphate (found in ribonucleotides) Analogues of the above that mimic the nucleobase arrangement and allow base pairing The MPEP also provides examples of alternative backbone moieties: “examples…

How does the MPEP address nucleotide analogs in its definition?

The MPEP 2412.03(d) includes nucleotide analogs in its comprehensive definition of nucleotides. Specifically, it states: “‘Nucleotide’ includes any nucleotide, nucleotide analog, or modified nucleotide as defined in paragraphs 3(f) and 3(g) of WIPO Standard ST.26.” The MPEP further elaborates on nucleotide analogs by describing backbone moieties that can be part of these structures: “an analogue…
