Material Changes and Event Details
- Patent Revocation: On January 15, 2026, the Board of Appeal of the European Patent Office (EPO) verbally revoked Arbutus's European patent EP 2279254 (the "'254 Patent").
- Opposition Context: The revocation followed Notices of Opposition filed in April 2018 by affiliates of Moderna Therapeutics, Inc. and Merck, Sharp & Dohme Corporation.
- Legal Basis: The decision was based on an EPO standard of "added matter," which the Company notes does not apply in the United States or other jurisdictions where it has initiated patent infringement litigation.
- Impact on Litigation: The decision is likely to affect cases against Moderna in Switzerland and one of two cases in the Unified Patent Court (Case UPC_CFI_191/2025) where the '254 Patent is asserted.
- Unaffected Litigation: The Company does not expect this decision to impact pending litigation against Moderna in the United States, Japan, or Canada, the second Unified Patent Court case (Case UPC_CFI_192/2025), or litigation against Pfizer Inc. and BioNTech SE in the United States.
Guidance, Outlook, and Risks
- Management Action: Arbutus disagrees with the outcome and plans to file a petition for review by the Enlarged Board of Appeal of the EPO upon receipt of the written decision, expected in the next few months.
- Forward-Looking Statements: The filing includes statements regarding the impact of the EPO decision on ongoing litigation and expected timing, which are subject to significant uncertainties.
- Risk Factors: Key risks include uncertainties associated with patent litigation, worsening economic conditions, potential strategic shifts, and risks related to the sufficiency of cash resources for operating expenses and capital expenditures.
Investor Verification Checklist
- Verify the receipt and content of the written EPO decision expected in the coming months.
- Monitor the status of the petition for review by the Enlarged Board of Appeal of the EPO.
- Track the specific impact of the patent revocation on the Swiss and Unified Patent Court (Case UPC_CFI_191/2025) proceedings against Moderna.
- Review the Company's cash resources and burn rate in subsequent 10-Q or 10-K filings to assess liquidity given the ongoing litigation costs.
- Confirm that litigation in the United States, Japan, Canada, and against Pfizer/BioNTech remains unaffected as stated.
