Protein Similarity Score: Simplified Version Of The Blast Score As Superior Alternative To Percent Identity For Claiming Genuses Of Related Protein Sequences, Christopher M. Holman

Faculty Works

Recombinant proteins form the basis for most of the products of biotechnology, including drugs, diagnostics, research reagents, genetically modified organisms and industrial enzymes. However, the nature of proteins and the rules of patentability conspire to make it difficult to achieve adequate patent protection for novel proteins and the polynucleotides that encode them. Narrow patent claims limited to protein sequences sharing a high degree of structural identity can generally be designed around by introducing structural changes in the claimed protein, thereby avoiding the patent without substantially altering the protein's function. However, inventors are generally restricted in their ability to broadly claim …
