In the United States, the legal protection of intellectual property rights has a long history. 1789, Chapter 1, Article 8, Paragraph 8 of the Constitution, points out that Congress has the right to "guarantee the exclusive rights of writers and inventors to their respective works and inventions for a certain period of time, so as to promote the progress of science and practical arts". Since then, the United States has enacted patent law, trademark law, copyright law, anti-unfair competition law, internet law and software patents. In order to fully fulfill the obligations stipulated in the Agreement on Trade-related Aspects of Intellectual Property Rights of the World Trade Organization, the US government promulgated the Uruguay Round Agreement Law on February 8, 1994, which further revised and improved the intellectual property law.
