Independent claim

IntermediateInventorEngineerIP professional

If someone asks how broad your patent is, they are really asking about one sentence: claim 1.

In simple words
A claim that stands on its own and does not refer back to any other claim. It defines the widest thing the patent protects.
Think of it as
The outer fence. Everything else is fencing inside it.
Why it matters
Claim 1 usually decides commercial value. It is also the claim an opponent attacks first, because knocking it out shrinks the patent to whatever narrower claims survive.
A simple example
Claim 1: “A pump comprising A, B and C.” Anyone who makes a pump with A, B and C infringes - whether or not they also add D, E and F. Adding extra features of their own does not get them out.
Common mistake
Writing claim 1 to describe the product you actually launched. The product is one embodiment; claim 1 should cover the invention, including the versions your competitor will build.
