The UK Government has issued a consultation over the introduction of a preferential regime for profits arising from patents, known as a Patent Box. Apparently, this will allow companies to apply a 10% corporation tax rate to profits derived from UK & EPO issued patents.
The move is designed to encourage companies to locate high-value jobs and activity associated with the development, manufacturing and exploitation of patents in the UK and enhance the competitiveness of the UK tax system for high-tech companies that obtain profits from patents.
I don’t quite know (yet) how this will work (or whether it will in fact have tangible results to all that treasure everything patenty!), but more details can be found here.
