The method for NRI calculations is patented, European patent No 1383913, US Patent No. 7,465,559. The use of NRI in pure research is recommended and provides a powerful tool for analysing MIC and zone size distributions in individual laboratories. For commercial applications a license is required. Request further information from the patent holder, Bioscand AB, Täby, Sweden.
