How Are the Patent Claims Structured?
The patent contains 16 claims, divided into independent and dependent claims:
Independent Claims
- Claim 1: A recombinant DNA construct comprising a DNA sequence encoding a polypeptide selected from the group consisting of specified amino acid sequences with particular functional properties.
- Claim 9: A method for producing the polypeptide, involving the transformation of a host cell with the DNA construct, cultivation under specific conditions, and recovery of the polypeptide.
Dependent Claims
- These specify particular sequences, host cells (e.g., Escherichia coli, Saccharomyces cerevisiae), vectors, and cultivation conditions, narrowing the scope to specific embodiments.
Key Elements of Claims
- Specific amino acid sequences, which include at least 80% identity to a reference sequence.
- Recombinant DNA constructs with features like promoters, terminators, and selection markers.
- Methods involving transformation, fermentation, and purification processes.
