In October 2017 the IP Office of the Philippines (IPOPHL) was made an international searching authority and international preliminary examining authority under the Patent Cooperation Treaty – a move that is hoped to energise local innovation and give the country a more globally competitive knowledge economy. The IPOPHL has also launched a national IP strategy to instil awareness of intellectual property into the national consciousness and, eventually, make patent rights as commercially valuable as they are in other Asian countries such as China, Korea, Japan and Taiwan.
