In spite of spending hours on end at the keyboard I still periodically find a site or search engine that I am unaware of. Google Patents is a search engine especially for patents. If you are bored at the office or anywhere else you can search for patents. You can see if someone you know has a patent. You can also discover some of the strange things that are patented. The baby diaper that announces the child is wet by changes in conductivity of a charge running though the diaper and sets off an alarm. I am sure that the people who make Huggies are going to jump right on that. Just one more way that the Internet is enhancing our lives.
