When Was Established The Intellectual Property Association?

I'm sorry, but there is no single 'Intellectual Property Association' that exists worldwide. There are many organizations and associations related to intellectual property that have been established over the years, each with their own specific focus and scope.

Some of the most well-known organizations related to intellectual property include the World Intellectual Property Organization (WIPO), the International Association for the Protection of Intellectual Property (AIPPI), and the Intellectual Property Owners Association (IPO).

WIPO was established in 1967 as a specialized agency of the United Nations, with the goal of promoting the use and protection of intellectual property worldwide. AIPPI was established in 1897 and is an international organization focused on the development of intellectual property law. IPO was established in 1972 and is a trade association representing owners of patents, trademarks, copyrights, and trade secrets.

It's worth noting that different countries may have their own organizations and associations related to intellectual property, so the specific answer to this question will depend on the context and location in question.
