Arbutus Biopharma and its licensee Genevant have filed three international lawsuits against Pfizer and BioNTech to enforce patents on their lipid nanoparticle (LNP) technology used in COVID-19 vaccines. They seek monetary damages and injunctions against Pfizer/BioNTech's infringing products. Arbutus also received $178 million from Moderna as part of a settlement resolving patent disputes over Moderna’s COVID-19 vaccines. The company expects a dividend from Genevant in Q3 2026 and plans to return up to $230 million to shareholders through share repurchases starting in Q3 2026, pending board approval.
