Dependent claim
Claim 1 is the one everyone talks about. Claims 2 to 15 are the ones that save the patent when claim 1 falls.
- In simple words
- A claim that refers back to an earlier claim and adds something to it. It is automatically narrower than the claim it depends on.
- Think of it as
- Fallback positions, arranged from broad to specific.
- Why it matters
- When prior art destroys claim 1, a well-built set of dependent claims gives you somewhere to retreat to without redrafting from scratch - and without adding matter you never disclosed.
- A simple example
- Claim 1: a pump with A, B and C. Claim 2: the pump of claim 1, wherein C is made of titanium. If a 1998 document shows A, B and C, claim 1 is gone - but claim 2 may survive if nobody ever used titanium there.
- Common mistake
- Filling dependent claims with trivial variations that no competitor would ever need. Useful dependent claims capture the features that actually make the invention work.
- Where it comes from
- Patents Act 1970 - section 10(4)(c) and 10(5)
