So it's being suggested that patents should be peer reviewed:
The UK Patent Office is considering how it might implement some of the recommendations of the Gowers Review of intellectual property law in the UK. One of the suggestions Gowers made in the report was that the patent authorities should evaluate how peer review might improve the patent checking process.
Specifically, recommendation 23 says: "The Patent Office should conduct a pilot of Beth Noveck's Community Patent Review in 2007 in the UK to determine whether this would have a positive impact on the quality of the patent stock."
Not sure if this is exactly what needs to be be done but something certainly does have to be.
