Claim Construction

Definition

Claim construction is the legal process by which a court determines the meaning and scope of the words in a patent claim.

Why It Matters Legally

Claim construction frequently decides the outcome of a case, since how a key term is defined can determine whether a product infringes or whether a claim is valid. It is one of the most contested phases of litigation.

Example Use Case

The parties dispute the meaning of the word ‘connected’ in a claim, and the court’s construction determines whether the accused product infringes.
