"PagCal" wrote in message ... Has anyone looked at this patent? See http://l2.espacenet.com/espacenet/viewer?PN=WO0245210 for details. It's basically a coil wrapped around a ferrite rod/tube that sensitive to the magnetic part of the electromagnetic field. The author claims it can be built small, handle high power, and is mostly omni-directional. They also went to the trouble of patenting it in Canada, number CA2427575, but I can find no US patent. doesn't look like anything special, but then again you don't have to have anything really special to get a patent... Absolutely correct since every thing is now known ! We have a lot of very educated experts in the antenna field that can attest to that. If it is not already printed in a book or was not presented as something new found by an expert then it most certainly a case of snake oil or something that was obvious but useless. Sounds like you have been succesful in the patent field and thus can talk from personal experience, care to share some of these 'useles' patents that you have to illustrate your point? Regards Art heck, the device doesn't even have to work. someone has patented an antenna that sends signals faster than light, if i remember right it was basically a halogen floodlight tube with a coil around it and a bunch of other junk... as an additional claim they claimed it helped plants grow, which is probably the only claim they could prove if they were ever asked to. |
