Grantback Clauses Law and Legal Definition

In patent law, as a condition to a license agreement, a patentee will sometimes require the licensee to grant it rights to any improvement patents or any other new technology that the licensee develops while using the patented technology. The imposition of such a licensing restriction is termed as a grantback of rights. Such a grantback of rights is periodically alleged to constitute patent misuse. Grantback clauses can have both pro-competitive and anti-competitive effects.
