Radio 'Fences' and Inventor Attention to Property Rights: Evidence from Wireless Patents

Do the inventors of radio “fences” (which restrict transmissions externalities) care about property rights? I hypothesize that inventors do pay attention to policy regimes such as licensed and unlicensed spectrum when building technologies to handle interference. To answer this question, I conduct textual analysis of 500,000 wireless patents to estimate inventor attention to property rights. I find that inventors are more likely to mention interference and sensor technology if they mention property rights, than if they do not discuss property rights. While further research is needed to determine causality, textual analysis provides evidence of inventor attention to property rights regimes.
