Let's bring an example (note I am naive in writing or understanding claims):
Independent claim 1: It is an awesome equipment to detect X,
dependent claim 2: the equipment of claim 1 detects X using a fork.
Could they reject it because an equipment to detect X already exists (no matter if they use spoon in their dependent claims)?
For example if I write it as:
Independent claim 1: It is an awesome equipment to detect X using a fork
Then could it be accepted because there is "fork" in independent claim while the independent claim of the others was general?!
