The invention is a tool that has a least one of feature Y on a first location. Then in preferred embodiments have feature Y in a second location and also different possible configurations and numbers of Y on the tool.
My question is how do I introduce Y correctly and still have it make sense with the dependent wording? I find many articles I read say you must preferably
use "a" or "an" to introduce an element. What is the best most clear way to make an examiner happy?
Example 1: Independent claim: Tool, comprising: X with a first location and a second location; and at least one Y on the first location.
Dependent claim: The tool defined in claim 1, wherein at least one said Y is also located on the second location.
Example 2:
Independent claim: Tool, comprising: X with a first location, and a second location; and a
Y on the first location.
Dependent claim: The tool defined in claim 1, wherein at least one said Y is also located on the second location.
Example 3: Or should I say: at least one of a
Y? That way there is the proverbial a
, or does that even matter or help?
