NPEs initiate lawsuits primarily not to stop patent infringement, but for the potential monetary profits. We examine how firms shift their innovation strategies in response to heightened NPE litigation risks. We theorize and find that firms targeted by NPEs will subsequently draw more upon their in-house technologies to reduce the legal ground for such lawsuits, whereas firms in related technology areas will shift their innovation activities away from areas of high NPE litigation risks.enfalseFirm innovationInnovation activityInnovation strategyPatent infringementsPatent portfolioPatent trollsPatented technologyProduct processProduct service[SDGs]SDG9conference paper10.5465/ambpp.2022.1412-s2.0-85208739662
