It is business as usual on the Hungarian patent scene: filings are progressing apace, and pharmaceutical and life sciences skirmishes continue to account for most of the contentious work handled by legal professionals. Innovation is also a hot topic of late, with the local government looking to re-energise the country’s R&D scene by setting up several funding streams to incentivise entrepreneurs and see their ideas through to launch. The overall stability in the market is reflected in the rankings, which remain unchanged for 2020.
