German Pharma Company Challenges Extended Patent Protection

German pharmaceutical company Aristo has intensified its legal challenge against Takeda’s extended patent protections for Elvanse (known as Vyvanse in the US), a widely prescribed medication that supports focus development in children and adults. The case, now before London’s High Court, centers on whether Takeda’s supplementary protection certificate (SPC) should remain valid or be invalidated to allow generic competition.

Aristo first filed its challenge in November 2025, arguing that Takeda’s extended protections should not prevent competitors from entering the market. Takeda, which acquired the medication through its 2019 purchase of Shire, maintains that its UK supplementary protection certificate is valid and enforceable. The outcome could determine when lower-cost alternatives become available to UK families.
