The Conversation Continues: Some Post-Patent-Termination Royalties Are Acceptable

For the second time in less than two weeks, a circuit court decided an appeal hinging on the Brulotte rule, which holds that patent royalties are impermissible when based on payments for the use of expired patents. Like the US Court of Appeals for the Ninth Circuit, the Fourth Circuit upheld a royalty agreement that purported to require payments after patent expiration. Ares Trading S.A. v. Dyax Corp., Case No. 23-1487 (4th Cir. Aug. 14, 2024) (Krauser, Porter, Chung, JJ.)

Dyax is a biotechnology company engaged in “phage display” research – a laboratory process used to identify antibody fragments for use in developing medications. Dyax holds multiple patents related to phage display, including licenses to patents owned by Cambridge Antibody Technology (CAT). Dyax and Ares entered a licensing agreement. Dyax’s main obligation was to use its phage display technology to identify antibody fragments and then provide those fragments to Ares so that Ares could incorporate them into commercial medications, including one called Bavencio. In exchange, Ares agreed to pay Dyax at various research milestones and pay royalties for identified products, including Bavencio. Although Bavencio was first sold in 2017, the last CAT patent expired in 2018.

After learning of the Brulotte rule, Ares tried to renegotiate its contract obligations. When renegotiation attempts failed, Ares sued Dyax, seeking multiple related declaratory judgments revolving around its argument that its royalty obligations to Dyax were unenforceable under Brulotte. Dyax countersued on six claims, including for declaratory judgment that Brulotte did not apply. The district court found the royalty obligation enforceable and not in violation of Brulotte. Ares appealed.

Ares asked the Fourth Circuit to reconsider the applicability of the Brulotte rule and to relatedly find that Dyax had breached the covenant of good faith and fair dealing. The Fourth Circuit first examined its own jurisdiction in the context of the Federal Circuit’s exclusive jurisdiction over patent appeals. Of the 10 total claims and counterclaims, nine arose under Massachusetts contract law. According to the Fourth Circuit, these were not “substantial” patent law claims and thus regional circuit appellate jurisdiction was appropriate.

The Fourth Circuit next turned to the Brulotte prohibition on post-termination royalties and found no violation because “Ares’ royalty obligation is not calculated based on activity requiring post-expiration use of inventions” covered by Dyax or CAT patents. The Court emphasized the policies underpinning the federal patent regime and the Brulotte rule, particularly the importance of inventions entering the public space once a patent expires to allow continued innovation and general use of the once-patented invention. The Court also explained its understanding of the nuances of Brulotte, as informed by the Supreme Court’s 2015 decision in Kimble v. Marvel. For instance, a court’s inquiry must focus on post-expiration use, so where “royalties are not calculated based on activity requiring post-expiration use, they do not hinder post-expiration use ‘on their face’ and Brulotte is not implicated.” In the present case, this was a key delineation because the Fourth Circuit found that Ares’ [...]

Some Post-Expiration Patent Royalty Payments May Be OK

The US Court of Appeals for the Ninth Circuit reversed a district court’s finding that a contract impermissibly allowed for patent royalties after the patent expired because the post-termination royalty payments were allocated to non-US patents. C.R. Bard, Inc. v. Atrium Med. Corp., Case No. 23-16020 (9th Cir. Aug. 23, 2024) (Friedland, Mendoza, Desai, JJ.) (per curiam).

C.R. Bard held one US and one Canadian patent covering a type of vascular graft. In 2011, Bard and Atrium entered a licensing agreement to settle a patent dispute. Under the terms of the agreement, Atrium agreed to pay Bard a 15% royalty on covered US sales until 2019 (when the US patent expired) and a 15% royalty on covered Canadian sales until 2024 (when the Canadian patent expired). The contract also included a quarterly royalty minimum. Through 2019, as the contract contemplated, Atrium paid royalties on its US and Canadian sales. Because of a US Food and Drug Administration delay, Atrium had lower than expected sales and never exceeded the quarterly minimum royalty.

Atrium eventually refused to continue making royalty payments, which after 2019 covered only Canadian sales (likewise never exceeding the quarterly minimum). Bard sued for breach of contract in 2021. Atrium argued that the royalty provision was unenforceable under Brulotte v. Thys, a 1964 US Supreme Court decision holding that collecting royalties for patent use after a patent’s expiration constitutes patent misuse. The district court determined that the “clear and primary purpose” of the parties’ contractual minimum royalty was to compensate Bard for US sales of the patented product. The district court therefore agreed with Atrium. Bard appealed.

The Ninth Circuit undertook to determine whether the terms of the parties’ contract constituted patent misuse under Brulotte. The Ninth Circuit first explained that in Brulotte, the Supreme Court considered a contract between the owner of multiple patents related to picking hops and farmers who made seasonal license payments to use machines incorporating those patents. The Supreme Court found patent misuse because the license amount did not decrease as patents incorporated into the machines expired, which indicated that the farmers were paying to use expired patents.

Despite pushback, the Supreme Court refused to overturn Brulotte in 2015 when it decided Kimble v. Marvel. That case involved a patent holder’s license allowing Marvel to incorporate patented web-shooting technology into a Spiderman toy. In Kimble, the Ninth Circuit had ruled that the license agreement was invalid under Brulotte because it required Marvel to continue to pay a royalty fee after the patent expired. The Ninth Circuit noted, however, that an ongoing license after the expiration of a patent may be permissible if the license contemplates both patented and non-patented features, as long as the terms of the royalty adjust when the patent expires. For instance, a license covering both a patented invention and a trade secret may continue past the life of the patent, as long as the royalty rate diminishes after the patent expires. This reflects that the royalty is [...]
