Non-Standard Amino Acids in Patent Sequence Listings: Encoding and Disclosure Rule
Introduction Biotechnology and pharmaceutical innovation increasingly extends beyond the twenty naturally occurring amino acids that form the foundation of most proteins. Advances in peptide engineering, synthetic biology, protein therapeutics, antibody development and biomolecular design have led to the widespread use of non-standard amino acids (NSAAs) to enhance stability, bioavailability, target specificity and therapeutic performance.As these […]
Modified Nucleotides in Sequence Listings: ST.26 Compliance for Non-Standard Bases
Introduction Modern biotechnology has outgrown the simplicity of the four-letter genetic alphabet. Today’s nucleotide sequences often include chemically modified bases engineered to improve stability, reduce immune response, or enhance binding efficiency. These innovations are not theoretical—they are the backbone of real-world therapeutics such as mRNA vaccines, antisense oligonucleotides, and gene-editing systems. But as molecular design […]
Aptamer Sequence Listings in Patent Applications: Disclosure, Compliance and Global Strategy Guide
Prelude Aptamers represent one of the most refined intersections of molecular biology and modern intellectual property law. These short, single-stranded DNA or RNA molecules are capable of folding into highly specific three-dimensional structures that bind to target molecules with antibody-like precision. Their applications span diagnostics, therapeutics, biosensing, drug delivery, imaging and precision medicine. Yet, despite […]
Nanobody and Single-Domain Antibody Sequence Listings: Patent Filing Requirements (Deep-Dive Guide)
Prelude Nanobodies and single-domain antibodies (sdAbs) sit at a very interesting intersection of biotechnology and patent law. Scientifically, they are elegant and compact binding domains derived from heavy-chain-only antibodies. Legally, they are among the most sequence-sensitive inventions in the entire life sciences patent landscape. Unlike chemical inventions, where a structure can often be summarized in […]
Bispecific Antibody Sequence Listings: Patent Disclosure Strategies and Requirements
Introduction Bispecific antibodies represent one of the most sophisticated modalities in modern biologics, engineered to bind two distinct antigens or epitopes within a single molecular construct. This dual-targeting capability enables powerful therapeutic mechanisms such as T-cell redirection, tumor microenvironment modulation and multi-pathway inhibition – particularly in oncology and immune-mediated diseases. However, this therapeutic complexity translates […]
Antisense Oligonucleotide Patent Sequence Listings: Regulatory Compliance Essentials
Introduction Antisense oligonucleotides (ASOs) are among the most sequence-dependent inventions in biotechnology, with their identity, function and therapeutic effect directly tied to their nucleotide sequence. As a result, accurate sequence listing preparation is critical for patent protection. The presence of backbone, sugar and base modifications—key to ASO performance—creates additional compliance challenges under WIPO Standard ST.26. […]
Brazil INPI Sequence Listing Requirements for Biotech Patent Applications (ST.26 Standard)
1. Introduction Biotechnology patent filings increasingly depend on precise disclosure of nucleotide and amino acid sequences. In Brazil, the National Institute of Industrial Property (INPI Brazil) has aligned its formal requirements with international standards governed by the World Intellectual Property Organization (WIPO). Since 1 July 2022, Brazil has fully adopted WIPO Standard ST.26, replacing the […]
