Named as the world’s most innovative nation by the World Intellectual Property Organisation two years in a row, Switzerland looks set to retain its crown in 2020: the IP regime became even more favourable for inventors and companies seeking to unleash their creative potential when the ‘patent box’ came into effect on 1 January. The incentive aims to reduce cantonal corporate income tax rates on patent-derived profits by up to 90%; cantons can also apply for further reductions of up to 50% in relation to R&D expenditure activities performed within the country. The future of the Swiss Federal Institute of Intellectual Property appears equally bright: it is modernising its register; grants are on a stable trajectory; and recent legislative revisions have extended the terms of supplementary protection certificates (SPCs), aligning Swiss protocol with European Court of Justice case law. The country’s practitioners are already ahead of the game when it comes to the patent world’s hottest topics, as some have already sunk their teeth into precedent-setting cases in the artificial intelligence, biosimilar and fintech spaces.
