Angola does not have an IP policy ( see the country's WIPOLex entry here). IP has been considered in the context of other national policies, albeit briefly. The Angolan government launched a Science, Technology and Innovation (STI) framework in 2011, which consists of a National Policy for STI (NPSTI), a National Strategy for STI (NSSTI) and a Coordinating Mechanism of the National System of STI (CMNSSTI). The NPSTI briefly refers to IP but does not articulate an IP policy.
This Leo was unable to find any information on the preparation of an IP policy. However, according to the WIPO Technical Assistance Database, Angola was a participant in the African Conference on the Strategic Importance of IP Policies to foster Innovation, Value Creation and Competitiveness and the ECOSOC Regional Preparatory Meeting held in Tanzania in March 2013 (see conference program here and Kingsley's comments on these events here). Perhaps such participation is indicative if the country's intention to draft an IP policy in the future?
