Objections to overly broad intellectual property laws.

Some critics of intellectual property, such as those in the free culture movement, point at intellectual monopolies as harming health (in the case of pharmaceutical patents), preventing progress, and benefiting concentrated interests to the detriment of the masses, and argue that the public interest is harmed by ever-expansive monopolies in the form of copyright extensions, software patents, and business method patents. More recently scientists and engineers are expressing concern that patent thickets are undermining technological development even in high-tech fields like nanotechnology.

Petra Moser has asserted that historical analysis suggests that intellectual property laws may harm innovation:

Overall, the weight of the existing historical evidence suggests that patent policies, which grant strong intellectual property rights to early generations of inventors, may discourage innovation. On the contrary, policies that encourage the diffusion of ideas and modify patent laws to facilitate entry and encourage competition may be an effective mechanism to encourage innovation.

In support of that argument, Jörg Baten, Nicola Bianchi and Petra Moser find historical evidence that especially compulsory licensing – which allows governments to license patents without the consent of patent-owners – encouraged invention in Germany in the early 20th century by increasing the threat of competition in fields with low pre-existing levels of competition.

Peter Drahos notes, "Property rights confer authority over resources. When authority is granted to the few over resources on which the many depend, the few gain power over the goals of the many. This has consequences for both political and economic freedom within a society."

The World Intellectual Property Organization (WIPO) recognizes that conflicts may exist between the respect for and implementation of current intellectual property systems and other human rights. In 2001 the UN Committee on Economic, Social and Cultural Rights issued a document called "Human rights and intellectual property" that argued that intellectual property tends to be governed by economic goals when it should be viewed primarily as a social product; in order to serve human well-being, intellectual property systems must respect and conform to human rights laws. According to the Committee, when systems fail to do so, they risk infringing upon the human right to food and health, and to cultural participation and scientific benefits. In 2004 the General Assembly of WIPO adopted The Geneva Declaration on the Future of the World Intellectual Property Organization which argues that WIPO should "focus more on the needs of developing countries, and to view IP as one of many tools for development—not as an end in itself".

Ethical problems are most pertinent when socially valuable goods like life-saving medicines are given IP protection. While the application of IP rights can allow companies to charge higher than the marginal cost of production in order to recoup the costs of research and development, the price may exclude from the market anyone who cannot afford the cost of the product, in this case a life-saving drug. "An IPR driven regime is therefore not a regime that is conducive to the investment of R&D of products that are socially valuable to predominantly poor populations".
