FAQ
1. Can this patent block new COVID-19 drugs?
No. It primarily covers therapeutic methods involving known drugs, not new chemical entities.
2. How enforceable are these claims?
Claims are enforceable if their scope is limited to specific dosages and combinations. Broad claims without specific limitations may face validity challenges.
3. Are similar patents filed in other jurisdictions?
Yes. Related filings exist in the US, Europe, and China, with similar claims focusing on COVID-19 therapies.
4. What risks exist for companies developing COVID-19 treatments in Australia?
