Practice question: multiple dependent claims
Answer in brief
This question tests the form of multiple dependent claims. Pick an answer before you open the explanation; the governing rule is in MPEP 608.01(n).
An original practice question written by Wysebridge in the style of the exam. It is not a released USPTO question.
The question
Claim 5 reads: "The device of claim 3 or 4, further comprising a hinge." Claim 4 is itself a multiple dependent claim. Is claim 5 proper?
- Yes; any claim may refer to any earlier claim.
- No; a multiple dependent claim may not serve as a basis for any other multiple dependent claim.
- Yes, if the applicant pays a surcharge.
- No; multiple dependent claims must refer to the earlier claims in the conjunctive ("and").
- Yes, because claim 3 is a single dependent claim.
Answer and explanation
Show the answer
Answer: B. A multiple dependent claim must refer back to earlier claims in the alternative only, and it may not serve as a basis for any other multiple dependent claim. Because claim 4 is multiple dependent, claim 5 cannot depend from it.
Where the rule lives
Read MPEP 608.01(n) explained on MPEP.net, then find it in the official MPEP. On test day you will search the same text, so practice locating it yourself.
