Clone is a one on one copy. Something that looks very much the same and function the same.
Those are not clone.
Its like saying Bambino is a clone of Derringer Atty.
Well Luxt in my opinion the bambino is a clone of the Derringer. Look how much money the Group Men at work had to pay for copyright infringement because they borrowed the beat from another song that noobr had ever heard of when the arrangement and the lyrics was completely redone.
I keep expecting Warren Zevon go file a lawsuit against Kid Rock. The beginning of both songs are identical not just the beat
Anytime you borrow ideas from someone's intellectual property you are cloning. Not a 1 to 1 clone with the same logo it is a clone none the less.
I build alcohol stoves and everyone tells me I should patent or trademarks my design.
I can't do it because I borrowed ideas from Intense Angler's v8 stove, and used the idea from smomeeater's Roll over stove to solve the cold ppt flame out problem
But the jets were completely my own design and the alcohol in my Ultimate stove burns twice as long as the same amount of alcohol will burn in either the v8 or the Rollover stove either one.
All of the stove builders thinks it is essential that the jets be 5/8 inch 18 mm from the top and have 16-21 jets.
My ultimate stove has 15 jetd that is 1/5 of an inch 5 mm from the top and only needs 40℅ as much fuel as the other stoves.
That is why thru hikers like my stoves. They carry less fuel and this means less Weight on their back.
