World Intellectual Property Day is observed on April 26, 2018. The event was established by the World Intellectual Property Organization in 2000 to "raise awareness of how patents, copyright, trademarks and designs impact on daily life" and "to celebrate creativity, and the contribution made by creators and innovators to the development of societies across the globe".
April 26th was chosen as the date for World Intellectual Property Day because it coincides with the date on which the Convention Establishing the World Intellectual Property Organization entered into force in 1970. The World Intellectual Property Organization is one of the specialized agencies of the United Nations.
Intellectual property is a legal concept which refers to creations of the mind for which exclusive rights are recognized. Under intellectual property law, owners are granted certain exclusive rights to a variety of intangible assets, such as musical, literary, and artistic works. Common types of intellectual property rights include copyright, trademarks, patents, industrial design rights, trade dress, and in some jurisdictions trade secrets. (With material from: Wikipedia)
