Financial incentive.

These exclusive rights allow owners of intellectual property to benefit from the property they have created, providing a financial incentive for the creation of an investment in intellectual property, and, in case of patents, pay associated research and development costs. In the United States Article 1 Section 8 Clause 8 of the Constitution, commonly called the Patent and Copyright Clause, reads; "The Congress shall have power 'To promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries.'" ”Some commentators, such as David Levine and Michele Boldrin, dispute this justification.

In 2013 the United States Patent & Trademark Office approximated that the worth of intellectual property to the U.S. economy is more than US $5 trillion and creates employment for an estimated 18 million American people. The value of intellectual property is considered similarly high in other developed nations, such as those in the European Union. In the UK, IP has become a recognised asset class for use in pension-led funding and other types of business finance. However, in 2013, the UK Intellectual Property Office stated: "There are millions of intangible business assets whose value is either not being leveraged at all, or only being leveraged inadvertently".

Economic growth.

The WIPO treaty and several related international agreements underline that the protection of intellectual property rights is essential to maintaining economic growth. The WIPO Intellectual Property Handbook gives two reasons for intellectual property laws:

One is to give statutory expression to the moral and economic rights of creators in their creations and the rights of the public in access to those creations. The second is to promote, as a deliberate act of Government policy, creativity and the dissemination and application of its results and to encourage fair trading which would contribute to economic and social development.

The Anti-Counterfeiting Trade Agreement (ACTA) states that "effective enforcement of intellectual property rights is critical to sustaining economic growth across all industries and globally".

Economists estimate that two-thirds of the value of large businesses in the United States can be traced to intangible assets. "IP-intensive industries" are estimated to generate 72% more value added (price minus material cost) per employee than "non-IP-intensive industries".

A joint research project of the WIPO and the United Nations University measuring the impact of IP systems on six Asian countries found "a positive correlation between the strengthening of the IP system and subsequent economic growth."
