I'm not any kind of a lawyer, nor am I knowledgeable about patents, but this
part sounds somewhat disturbing. The way I read it, this point/claim
involves taking two (studs-up) subassemblies, and placing the second
subassembly at any position and angle relative to the first subassembly (in
short, SNOT building).
Constraining the representation in this way is perhaps less efficient than
allowing any part to be mounted in any way, but the end results are the same
(if you allow the degenerate case of 1-part subassemblies).
But maybe I'm mis-reading the verbiage.
