It may be costly and sometimes ineffective to police property rights, but that does not make them less of a right. Efficiency and Justice are not the same thing. If firms feel they can benefit from fighting infringers of their intellectual property rights, it is their right to do so. The state likewise, has an obligation to protect the rights, physical and intangible, of its citizens and cannot give up on them simply because they prove difficult and costly to enforce. For the state the costs accrued by efforts to enforce intellectual property are repaid many fold by the fact that businesses feel safer to invest in them due to the perceived protections the state promises.
