What it's about

The Supreme Court ruled that an inaccurate registration may still receive the Copyright Act’s protection when the owner lacked knowledge of either the relevant facts or the law, wiped out the Ninth Circuit’s judgment, and sent the case back to the lower court (vacated and remanded).

The case addressed how copyright law treats mistakes in registration applications and whether courts must involve the Copyright Office.

Question presented

Did the Ninth Circuit err in breaking with its own prior precedent and the findings of other circuits and the Copyright Office in holding that 17 U.S.C. § 411 requires referral to the Copyright Office where there is no indicia of fraud or material error as to the work at issue in the subject copyright registration?

What the Court decided

Holding

Section 411(b) does not distinguish between a mistake of law and a mistake of fact; lack of either factual or legal knowledge can excuse an inaccuracy in a copyright registration under §411(b)(1)(A)’s safe harbor. 959 F. 3d 1194, vacated and remanded.

From the opinions

“Because I would not reward Unicolors for its legerdemain, and because no other court had, before today, ever addressed whether §411(b)(1)(A) requires “actual knowledge,” I would dismiss the writ of certiorari as improvidently granted.”

— Justice Thomas(dissent)

What's next

The Ninth Circuit will reconsider the dispute under the Supreme Court’s rule about factual and legal knowledge. The case remains open, including the final result of Unicolors’ copyright lawsuit against H&M.

Why it matters

The Ninth Circuit must reconsider this case, so the Supreme Court did not finally resolve the dispute between Unicolors and H&M.
