Impoundment

U.S. copyright law
Impoundment is a remedy available to a copyright owner under the 1976 Copyright Act. Section 503(a) of the Act provides:

"(a) At any time while an action under this title is pending, the court may order the impounding, on such terms as it may deem reasonable, of all copies or phonorecords claimed to have been made or used in violation of the copyright owner’s exclusive rights, and of all plates, molds, matrices, masters, tapes, film negatives, or other articles by means of which such copies or phonorecords may be reproduced."
