Re: For a contrasting view...
I'd suggest the best place to look would be at pharmaceutical patents, since some of the world's biggest pharma companies are UK-based. These last 20 years, so I'd suggest that if the likes of GSK haven't been churning out new ones, they'd be losing money, which they most definitely are not.
IIRC, they are largely based on manufacturing processes for chemical compounds, and not the compound themselves, so do meet the criterion for "novel" as well.
Without getting into the discussion about price-gouging of on-patent pharmaceuticals, I will point out that the drug discovery process is difficult, expensive, and littered with blind-alleys, so I do think this sort of patent has merit.
