Inventor Thomas Woolston's courtroom win in his business process patent lawsuit against eBay has not gone down too well with some. The patent concerns buying something at a fixed price over the internet. The victor is not happy with his critics claims that he should never have got a patent on such an obvious application of an idea: ``It's the combination of elements that defines the invention. There are 42 patents on the Post-It note. It's the combination of a not-so-good glue and a pad of paper,'' Woolston said. Whadaya know - 42 patents on the Post-It. I knew there were a lot but didn't realise it might be that high.
