Here's a dumb absolute beginner question: so I have in the claim something like
a first lever arm pivotally connected to the widget member at a first joint; a second lever arm pivotally connected to the first lever arm at a second joint;
Is it a problem if the first joint is named just for clarity and the claim never mentions it again, discussing only the role of the second joint? Are you expected to "use everything you introduce"? In software development, if you declare a variable you don't do anything with, you get a warning at quality check...
I'll try to clarify... I could write that part of the claim like
a first lever arm pivotally connected to the widget member; a second lever arm pivotally connected to the first lever arm at a first joint;
because the only joint I need to refer to later is the one connecting the first and second lever arms, but since that one is in reality the second joint in the chain of connected elements being defined, would that be confusing or better? (Since the first lever and the widget member are pivotally connected, there is a joint.)
