Bayer HealthCare has the lowest patent quality. This is illustrated by a very low share of granted patents (20%) and the lowest citation ratio (2.44). The patent activity of Mylan is very low compared to the other selected companies. This is caused by a small number of patents per family (SPF=4.82) and the smaller patent portfolio (NPF=281).
