WIPO was established in the 1970's with 183 members as an intergovernmental organisation. It served the purpose of promoting protection for members even though members were not obligated to sign all treaties. It facilitates the patent process for its members and promotes their services to industry and the private sector alike. It offers registration as well as renewal of trademarks as one of the major services. Also, mediation and arbitration, if necessary. 91% of WIPO income is generated from services and 7% comes from members. Its General Assembly meets once a year during September. WIPO employs 915 staff members from 94 different countries.
