I was reading a few posts of manufacturing New Sidewinders..
I am a Chemical Engineer and I file patents for my inventions and products all the time..
Here is my last Patent granted about 7 months ago..
I am a member of Patent Genius and Patent Doctor..
The Sidewinder patent D229104..looks like It has never been sold or assigned..so how are these people making clones when the hull is patent protected..
Just a thought..
Ken.R Baker..Sidewinder patent granted Sept 24/1971..D229104..Still Active..
