The internet should make it easier to search for existing "prior art" even if it is simply in common use by many people and not commercially produced. In the olden days it would have been more difficult. It seems today they issue patents for anything submitted and rely on the courts to decide later. They may be overworked and can not do an exhaustive search. The courts will decide eventually anyway. The picture I posted of the Lone Wolf stand has pretty much all the design features of the Predator platform only bigger. If they are patenting smallness then maybe that is novel. I read before you can DIY and use any patent for yourself and not for sale and not violate any patents but I am not sure if this is true.
