Dancing Doesn’t Matter – Federal Circuit Said Biosimilar Companies Must Wait 180 Days

Client Alert | 2 min read | 07.11.16

Last Tuesday, the Federal Circuit unanimously held that all biosimilar companies – even companies that participate in the so called “patent dance” – must notify brand-name rivals of their intent to sell a biosimilar drug 180 days before marketing the drug. The case, Amgen Inc., v. Apotex Inc. could have major implications for the timing of when biosimilar companies launch their drugs.

In this case, the Court affirmed the lower court’s ruling to preliminarily enjoin Apotex from putting its biosimilar version of Amgen’s white blood cell-boosting drug, Neulasta® (pegfilgrastim), on the market until the company received a license from the FDA and then gave Amgen 180 days pre-market notice.

Tuesday’s ruling is effectively an extension of the Court’s decision last year in Amgen Inc. v. Sandoz Inc. As we previously reported, the Court in Sandoz held that biosimilar companies that do not participate in the BPCIA’s optional “patent dance” (exchange of product and patent information, pursuant to 42 U.S.C. § 262(l)) must give the 180-day post-licensure notice before commercial marketing. Here, the Court extended Sandoz by requiring biosimilar companies that do participate in the BPCIA “patent dance” to also give the brand-name rival the 180-day post-licensure notice. The Court relied mostly on the plain language of the statute, holding that “shall” as used in conjunction with “licensed” in the BPCIA means that the 180-day post-licensure notice is mandatory. With regard to timing of the notice, the Court stated “…and we read (8)(A) [42 USC § 262(l)(8)(A)] as allowing the 180-day notice of commercial marketing to be sent as soon as the license issues, even if it is not yet effective, because it is at the time of the license that the product, its therapeutic uses, and its manufacturing processes are fixed.”

Perhaps to quell biosimilar companies’ fears, the Court pushed back against arguments that would seek to extend brand-name rival exclusivity from 12 years to 12.5 years. Writing for the unanimous Court, Judge Taranto wrote, “we have been pointed to no reason that the FDA may not issue a license before the 11.5-year mark and deem the license to take effect on the 12-year date.” Whether the FDA will approve biosimilar drugs before the 12-year exclusivity period expires remains an open question.

As a result of this Federal Circuit decision, biosimilar manufacturers must give brand rivals 180 days’ notice of marketing, after obtaining a license from the FDA for a biosimilar. This means that biosimilar manufacturers will have to factor this 180-day notice period into their strategy as an additional step of the “patent dance” under the BPCIA.

Twin Executive Orders Seek to Spur Quantum Leap in Technology and Cybersecurity

On June 22, 2026, President Trump signed two executive orders, “Securing the Nation Against Advanced Cryptographic Attacks” (Quantum Security EO) and “Ushering in the Next Frontier of Quantum Innovation” (Quantum Innovation EO), marking the most significant federal action on quantum technology since the Quantum Computing Cybersecurity Preparedness Act of 2022, which directed agencies to harden their information systems against quantum-enabled hacking. The orders seek to speed the development of quantum computers, which are advanced processors that can calculate multiple possibilities simultaneously and thus solve problems exponentially faster than traditional computers. At the same time, the orders look to protect against the danger that quantum technology can “break” traditional encryption by easily decoding it. Of particular note for government contractors, the Quantum Security EO directs agencies to update federal acquisition regulations to require contractors by 2031 to adopt information processing standards that resist quantum-enabled codebreaking....
