George is retiring from the Patent finding business - at least the ferreting out of the interesting ones for us - see his last post HERE. I hope that we are able to find another volunteer to take on this rewarding endeavour. Thank you very much George, we all appreciate the effort you have put in to this exercise, and the generosity you have shown in sharing it with us...
