this is why DSE puts patent on alot of the stuff they make.

I'm a designer and I have a couple design patents. Let me start off by telling you The Ringbrother hinge and the Fesler hinge are similiar. They are not a duplicate.

Ringbrothers hinge is an air frame design. The cut outs are all the way thru. The Fesler ones aren't they are just pockets. That alone is enough of a difference to state they didn't copy your design.

It stings a bit I know. You really have to move on and continue to come out with new products and build your brand up. You have to market your hinge as the First billet hinge and sell it as better quality than the competitors.
