Note(s): The values for the variables of the patent portfolio characteristics are available only for those companies having at least one patent at the date of the round of financing. For such reason, the variables from inventorsNbr to weiFwdCitsNbr show a smaller number of observations (726) than those calculated on the total sample (i.e. financedAmt, famDum, cumulFamNbr and firmAgeAtDeal)
