...So in answer to your question. I did not proceed beyond the Provision Patent that I received. I decided to put funds to development and saving on costs to pass on to others, like yourself. But if support is not given to designers then that makes it harder for me to put money aside for R&D. MY costs cover R&D, design, product cost, and support to evolve ideas from people like those on this forum.
Thanks for the clarification.
I think you were wise. There isn't much in this field that doesn't have a precedent in the forties and fifties, if not earlier - so, these things only benefit the lawyers...
