Patent Claims Explained: What Do They Protect?

Patent claims define the legal scope of protection sought in an application and granted in an issued patent. The description and drawings explain the invention, but they do not automatically make every described feature enforceable.

What is an independent claim?

An independent claim stands on its own and lists the limitations that define its subject matter. For literal infringement, every limitation must be met; other infringement doctrines can require separate analysis.

What does a dependent claim add?

A dependent claim incorporates another claim and adds a further limitation. It offers a narrower position that may matter if a broader claim encounters prior art.

Do provisional applications need claims?

Formal claims are not required for a US provisional application. Nevertheless, the disclosure must adequately support any later claims that seek its filing-date benefit.

Broader is not always better: a claim must satisfy legal requirements and be supported by the application. Adding missing technical material later generally cannot backdate that material to the original filing.
