Pfizer Inc, founded in 1849, is dedicated to better health and greater access to healthcare for people and their valued animals.
Pfizer IP attorney Guillaime Dufresne together with a research physician Laszlo Takacz and computational biologist Manuel Duval anticipated the complexity of large scale biosequence patent screening using biological search methods based on homology, a measure of evolutionary similarity and not identity, the method used to file patent claims for DNA and protein sequences. GenomeQuest scientists Jean-Jacques Codani and Henk Heus, having developed sequence comparison tools based on percent identity proposed a solution to Pfizer based on the company's proprietary "KERR" algorithm (tradename: GenePAST).
Together, GenomeQuest and Pfizer applied the technology and published in Nature Biotechnology what is now the seminal paper on percent identity searching to retrieve patent sequence records.
