tbh I knew all about patents on actual inventions, but this is the first time I have heard of an Intellectual Patent on a product.
So my understanding is the no one will be able to copy the stepped tube concept in any form. The spring loaded lateral clamps are protected by their own patent, but the telescopic nesting is the interesting one.
All telescopic poles have to close in a certain way that makes them as compact as possible. What are the implications for existing pole manufacturers, ie Facelift and what about those who are in the process of starting, Aquadapter?
