Material Changes and Legal Developments
On August 24, 2021, the Court of Appeal of England and Wales issued an opinion regarding FibroGen Inc.'s HIF-related patents:
- Upheld Invalidity: The court upheld the 2020 decision that European Patent Nos. 1633333 (UK), 2322153 (UK), and 2322155 (UK) were obvious and invalid.
- Overturned Invalidity: The court overturned the 2020 decision that invalidated European Patent No. 1463823 (UK), effectively restoring its validity.
- Unaddressed Patents: The judgment did not specifically address the validity of European Patent No. 2298301 (UK), which was previously held invalid.
- Non-Infringement: European Patent No. 2289531 (UK) remains valid but was found not to be infringed by vadadustat; this finding was not reviewed by the Court of Appeal.
- Expiration Dates: Patents Nos. 1463823 (UK), 2298301 (UK), and 2289531 (UK) are set to expire on December 6, 2022.
Guidance, Outlook, and Risks
The filing does not contain forward-looking guidance, management commentary on financial outlook, or a discussion of general business risks beyond the specific patent litigation outcome. The primary contingency noted is the mixed outcome of the appeal, which leaves the status of certain patents (specifically No. 2298301) unresolved while confirming the invalidity of others.
Investor Verification Checklist
- Verify the specific impact of the restored validity of Patent No. 1463823 (UK) on Akebia's product portfolio and potential infringement risks.
- Confirm the current legal status of European Patent No. 2298301 (UK), as the Court of Appeal did not address its validity.
- Review the expiration timeline (December 6, 2022) for the affected patents to assess the duration of any remaining patent protection.
- Check for subsequent filings or press releases detailing Akebia's strategic response to the Court of Appeal's judgment.
