PDF, Patent Landscape Report on Atazanavir - WIPO

ACTIVITY TIMELINES OF SELECTED COMPANIESThe timelines for the inventive activity in the same companies (using earliest priority yearfor each invention) are presented in Figure 26. The companies are ranked on the recencyof their activity. This presentation approach draws attention to recently active companies.Novartis, with the founder patents, has the earliest appearance in Figure 25, and it haspersistent later activity, as does its developer Bristol Myers Squibb. The top rank in thetable belongs to Enanta, a company with collaborative relationship to Abbott, also highlyranked in the table. Zirus (Herpes), Aicuris (synthesis) and Ranbaxy (synthesis) are allrecent entrants in the field of the collection. Abbott, GSK and Merck all have significantAtazanavir-relevant activity recently, mostly relating to combination therapy regimens orother indications. Recent Boehringer and Schering activity relate to other HIV targets(Boehringer) or Hepatitis Virus (Schering). The latter observations are suggested by acomparison with Figure 24 where technology emphasis was covered.Figure 26. Heat Diagram of Activity timelines32
