Twin Books v. Disney: How Bambi Survived a Missing Copyright Notice

The Ninth Circuit held that Bambi's 1923 German publication without notice neither injected it into the U.S. public domain nor started its copyright term.

Few copyright disputes turn on a single missing line of small print, but Twin Books Corp. v. Walt Disney Co., 83 F.3d 1162 (9th Cir. 1996), did exactly that. The United States Court of Appeals for the Ninth Circuit decided on May 20, 1996 whether Felix Salten’s 1923 German publication of Bambi, A Life in the Woods without a United States copyright notice had thrown the story into the American public domain. The court said no. That single ruling preserved a valuable renewal copyright, forced the Walt Disney Company to answer for its use of the fawn, and produced one of the most criticized formality rules in modern copyright law.

The stakes were concrete. Disney had built an animation empire partly on public-domain stories, and its 1942 film had made Bambi a household name. If the underlying book was free for all, Disney owed nothing. If instead the copyright had been secured in 1926 and validly renewed, Twin Books held enforceable rights. The panel’s answer, resting on how the 1909 Copyright Act treats publication abroad, still governs public-domain dating for pre-1978 foreign works in the circuit.

At a glance

  • Case: Twin Books Corp. v. Walt Disney Co., 83 F.3d 1162 (9th Cir. 1996).
  • Decided: May 20, 1996; Ninth Circuit panel; reversed the district court’s grant of summary judgment for Disney.
  • Holding: Publication of Bambi in Germany in 1923 without a U.S. copyright notice did not place the work in the U.S. public domain and did not start the U.S. copyright term, which began only with the 1926 publication that carried a proper notice.
  • Significance: The controlling Ninth Circuit rule on foreign publication and 1909 Act formalities, criticized by leading treatises but still binding for dating pre-1978 foreign works.

The 1909 Act formality that swallowed works whole

To understand the fight, start with the regime the 1909 Copyright Act imposed. Federal statutory copyright attached at publication, and publication was a formal event with teeth. A work published without the prescribed copyright notice generally forfeited protection and entered the public domain, sometimes irrevocably. This notice requirement was the great trap of pre-1978 practice: an author who distributed copies without the magic words and symbol could lose everything.

The initial federal term ran 28 years from the date copyright was secured, with a second 28-year renewal term available only if the claimant filed a renewal registration during the final year of the first term. Miss the renewal window and the work fell into the public domain even if the original notice had been perfect. Every date therefore mattered. Whether Bambi’s clock started in 1923 or 1926 decided whether the 1954 renewal was on time.

The facts: a fawn born in Germany, again and again

Felix Salten, an Austrian author, wrote Bambi, A Life in the Woods. The work first appeared in Germany in 1923, and that first printing carried no United States copyright notice. In 1926, Salten republished the German-language book in Germany, this time bearing a notice of United States copyright. The copyright was then timely registered in the United States in early 1927. Through a chain of transfers and renewals, the renewal interest eventually vested in Twin Books Corporation.

Disney’s use of the story flowed from a license granted decades earlier, but by the time of the litigation Disney contended it owed nothing because the book had never held a valid, subsisting United States copyright. Its theory was straightforward under 1909 Act orthodoxy: the 1923 publication without notice either forfeited the copyright outright or, at a minimum, started the clock in 1923. If the term ran from 1923, the initial 28-year term expired in 1951, no renewal was filed in the 1951 window, and Bambi was public domain.

What the district court held

The district court accepted Disney’s premise. It reasoned that Bambi’s United States copyright was secured in 1923 upon the initial German publication, that the first term therefore expired in 1951, and that because no renewal was filed at that time, the work had fallen into the public domain. On that view Disney was free to exploit the story, and the court granted summary judgment in Disney’s favor. Twin Books appealed.

The Ninth Circuit’s reversal: foreign publication without notice does nothing

The panel reversed. Its central move was to hold that publication abroad without a United States copyright notice neither placed Bambi in the American public domain nor commenced the American copyright term. Drawing on the Second Circuit’s classic decision in Heim v. Universal Pictures Co., 154 F.2d 480 (2d Cir. 1946), the court reasoned that a foreign publication has no effect on United States copyright unless the law of the country where it occurred put the work into the public domain there. Because no party contended that the 1923 printing had put Bambi into the public domain in Germany, that printing was, for United States purposes, as if it had not triggered the statutory scheme at all.

That logic led to a striking conclusion. If the 1923 publication did not start the clock, then copyright was secured only when the work was first published with a proper United States notice, which was the 1926 German edition. The initial 28-year term therefore ran from 1926 and expired in 1954, making the renewal filed in 1954 timely. The renewal copyright was consequently valid, and Disney’s public-domain defense collapsed. The panel reversed the district court’s findings that the copyright was secured in 1923, that the 1954 renewal was untimely, and that Bambi fell into the public domain in 1951, then remanded. Because that disposition resolved the appeal, the panel expressly did not reach whether a 1960 Presidential Proclamation could save an otherwise untimely renewal or whether licensee estoppel applies in a copyright case.

Why the decision drew fire

The holding is doctrinally awkward, and commentators said so immediately. The oddity is this: a work first published in 1923 does not obtain a United States copyright term measured from 1923, yet neither does it fall into the public domain. Instead it exists in a kind of suspended state until a later publication with notice starts the clock. Critics, including the Nimmer on Copyright treatise and copyright scholar William Patry, argued that this reading effectively rewards a defective first publication with a longer total term than a compliant one would have received, and that it conflicts with the ordinary rule that publication without notice forfeits protection.

The tension is real. Under a stricter reading, the 1923 publication without notice would have injected the work into the public domain, and nothing later could revive it. The panel avoided that result by characterizing foreign publication as a non-event for United States purposes absent forfeiture under local law. Whatever its theoretical difficulties, the practical effect was to extend the effective life of Bambi by measuring the term from 1926 rather than 1923, a difference that pushed the copyright decades into the future under the renewal and later term-extension statutes.

Open questions

  • Does foreign publication ever start the U.S. term? Twin Books says a foreign publication without notice does not, but it leaves unclear how to treat foreign publications that do carry notice, or works whose local-law status is ambiguous.
  • How far does the rule travel? The holding binds the Ninth Circuit, but other circuits and the Copyright Office have not uniformly embraced it, so the public-domain status of a pre-1978 foreign work can depend on where the question is litigated.
  • What about later restoration statutes? The interaction of Twin Books with copyright restoration for foreign works under the Uruguay Round Agreements Act adds another layer, since some foreign works that lost or never secured U.S. protection were later restored on different terms.

Implications for creators and businesses

  • Date every pre-1978 foreign work carefully. For works first published abroad before 1978, the public-domain analysis can hinge on which publication carried notice and where. Do not assume a foreign first printing forfeited or started the term without checking the governing circuit’s rule.
  • Treat circuit splits as diligence risk. Because Twin Books is not universally followed, a work that is arguably public domain under one circuit’s approach may be protected under the Ninth Circuit’s. Clearance opinions should identify the forum risk expressly.
  • Renewal timing still controls old catalogs. For 1909 Act works, a missed or mistimed renewal remains fatal. When acquiring or licensing older titles, verify the renewal chain against the correct term-start date, not merely the first appearance of the work.
  • Document the notice history. Keep records of which editions bore a United States copyright notice and when. In a dispute, that evidentiary trail is what separates a subsisting renewal copyright from a public-domain claim.

Frequently asked questions

Why didn’t Bambi fall into the U.S. public domain when it was published in 1923 without a copyright notice? Because the Ninth Circuit treated the 1923 German publication as not putting the work into the U.S. public domain. Under the 1909 Act, copyright was secured only when the work was published with proper notice, which happened in the 1926 German edition, so the U.S. term began in 1926.

What did the 1923-versus-1926 dating change? It moved the start of the initial 28-year copyright term. If the term ran from 1923, the 1954 renewal was too late and Bambi was public domain. Dating it to 1926 made the 1954 renewal timely, so the renewal copyright was valid and Disney’s public-domain defense failed. The Ninth Circuit reversed the summary judgment and remanded.

Is Twin Books still good law? It remains binding in the Ninth Circuit and is widely cited for pre-1978 foreign works, but scholars including Nimmer and William Patry have sharply criticized its reasoning. Other courts and the Copyright Office have not uniformly adopted it, so its rule is best treated as circuit-specific.
