Patent criticality
Why enablement and support are different objections
The examiner says my claim is not supported AND not enabled. What is the difference?
Support asks whether the claim is fairly based on what you described. Enablement asks whether a skilled person could actually perform it across the claim's width. They are answered by different evidence, and confusing them wastes the reply.
Support
A comparison between the claim and the description. The question is whether the description provides a basis for what the claim covers. The answer is to point to the passages, or to narrow to what is described. Argument about whether the invention works is irrelevant here.
Enablement
A question about whether a skilled reader could perform the invention without inventive effort of their own, over the whole scope claimed. The answer is technical: worked examples, parameters, conditions, and - where the claim covers a class - evidence that members across the class work.
A claim can be supported and insufficient. A claim to a range described in the specification but shown to work at only one point is exactly that.
The connection to breadth
Both objections tighten as the claim widens. That is why the right response to either is often to narrow to the scope you can actually justify, rather than to argue the claim as filed - provided the narrower scope was disclosed.
Section 10(4) and 10(5) of the Patents Act 1970; insufficiency as a revocation ground under section 64(1)(h).
Deal with the two objections in separate paragraphs of your reply. Merging them usually means neither is answered.
Answering a support objection with technical evidence, or an enablement objection with textual references.
Claims covering a class supported by a single example.
For each independent claim, note where in the specification the widest and narrowest ends of its scope are described.

A reply is an argument, not a form. What you concede now shapes what your patent is worth later.
