Paris Convention for the Protection of Industrial Property
The Paris Convention for the Protection of Industrial Property, signed in Paris, France, on 20 March 1883, was one of the first intellectual property treaties. It established a Union for the protection of industrial property. The Convention is currently still in force. The substantive provisions of the Convention fall into three main categories: national treatment, priority right and common rules. 
According to Articles 2 and 3 of this treaty, juristic and natural persons who are either national of or domiciled in a state party to the Convention shall, as regards the protection of industrial property, enjoy in all the other countries of the Union, the advantages that their respective laws grant to nationals.
In other words, when an applicant files an application for a patent or a trademark in a foreign country member of the Union, the application receives the same treatment as if it came from a national of this foreign country. Furthermore, if the intellectual property right is granted (e.g. if the applicant becomes owners of a patent or of a registered trademark), the owner benefits from the same protection and the same legal remedy against any infringement as if the owner was a national owner of this right.
The "Convention priority right", also called "Paris Convention priority right" or "Union priority right", was also established by Article 4 of this treaty. It provides that an applicant from one contracting State shall be able to use its first filing date (in one of the contracting State) as the effective filing date in another contracting State, provided that the applicant, or his successor in title, files a subsequent application within 6 months (for industrial designs and trademarks) or 12 months (for patents and utility models) from the first filing.
After a diplomatic conference in Paris in 1880, the Convention was signed in 1883 by 11 countries: Belgium, Brazil, France, Guatemala, Italy, the Netherlands, Portugal, El Salvador, Serbia, Spain and Switzerland. Guatemala, El Salvador and Serbia denounced and reapplied the convention via accession.
The Treaty was revised at Brussels, Belgium, on 14 December 1900, at Washington, United States, on 2 June 1911, at The Hague, Netherlands, on 6 November 1925, at London, United Kingdom, on 2 June 1934, at Lisbon, Portugal, on 31 October 1958, and at Stockholm, Sweden, on 14 July 1967, and was amended on 28 September 1979.
As of September 2014, the Convention has 176 contracting member countries, which makes it one of the most widely adopted treaties worldwide. Notably, Taiwan and Burma are not parties to the Convention. However, according to Article 27 of its Patent Act, Taiwan recognizes priority claims from contracting members.
