I have read that in patent drafting you have to be consistent with the terms you use. For example, if you refer to a “motor” in one place don't refer to it as “engine” in another place. What about word order? If in one place I talk about a “estimate of the orientation of the device” and in another place I talk about “orientation estimates”, would that rise any problems? Should I every time write “estimate of the orientation”?
I think at some point I have made this type of change to avoid sentences like “the A of the B of the C of the E”
