Assignment

Definition

An assignment is the legal transfer of ownership of a patent or application from one party to another, recorded to establish clear title.

Why It Matters Legally

Proper assignment creates a clean chain of title, which is vital for enforcement and transactions. Defective or unrecorded assignments can undermine a company’s ability to sue or sell a patent.

Example Use Case

Before an acquisition, a buyer reviews the assignment records to confirm the target company actually owns the patents it claims.
