On 6 February 2020, as the covid-19 pandemic began to rage across the country, the IP Office of the Philippines (IPOPHL) welcomed its new director general, Rowel S Barba. Determined to reach its goal of full digitalisation by the end of 2021, the IPOPHL continued on its digital transformation journey throughout the year. Among various updates, it launched online mediation proceedings and hearings, expanded its e-services offering to enable end-to-end electronic processing of IP registrations and protection, and introduced a mobile app to facilitate such services, including filings, registrations and making complaints against infringers. Filipino citizens are also becoming increasingly informed about intellectual property, especially as schools and researchers upskill their patent search capabilities. In addition, the government is further encouraging domestic innovation through the new Science and Technology Superhighway Project, which aims to fast-track 1,050 IP applications funded by the Department of Science and Technology. This growing thirst for innovation is not going unnoticed; the Philippines jumped four ranks to break into the top 50 in the 2020 Global Innovation Index.
