British government clowning around with patents -- but no-one's laughing

The IPKat is astounded to read, on the BBC's coverage of the British pre-budget report, a bullet-point which reads as follows:
"New 10% tax on income from patents to boost science development".
The Telegraph is more specific: Corporation Tax at the rate of 10% is to be introduced on income from patents. This, explains easyBourse, is "a bid to underpin the life sciences and technology industries" according to Chancellor Alastair Darling who reassuringly adds: "I want to encourage research into pharmaceuticals and the biotechnology industry".

On the assumption that this is not a practical joke, it now seems that the British government is set to tax the fruits of research and development in order to fund ... research and development. What a wonderful incentive to invest, particularly when other countries are encouraging R&D by doing the exact opposite. Merpel says, don't worry: Britain's best tax brains will soon find ways of showing that the income in question isn't derived from patents at all, and the government's coffers will be none the fuller.
