In the US, at present, there is virtually no review of patent
applications, and nearly anything can be patented.  The attitude is
that the patent is granted, and if there's something wrong with it the
courts can settle it later.  Here's the poster child for ridiculous

"Method of swinging on a swing", US Patent #6,368,227,368,227.PN.&OS=PN/6,368,227&RS=PN/6,368,227

One would have thought *somebody* in the patent office would have
remembered their own childhood well enough to remember just a little
bit of prior art...
