> Good job. But... if you publish your idea, then you can't get patent > protection. IMHO Roman has already published his design (on the internet and on the piclist), and granted use under his 'hippyware' license. Although not easy to prove in court, this is enough to - prevent him from patenting (you can't patent what you have already published) - prevent anyone else from patenting Of course a publication in a magazine will make the proving part much easier.
