- Patent Dispute Update: A federal judge in Delaware ruled that the patent dispute involving Moderna's mRNA COVID-19 vaccine should be settled in a jury trial, leading to a ~10% rise in Arbutus Biopharma's stock, reflecting market optimism about its potential success.
- Judge's Ruling Details: Judge Joshua Wolson noted that the prosecution history of some of Arbutus's patents limits its doctrine-of-equivalents claims based on Moderna's vaccine, indicating that Arbutus must prove literal infringement to succeed, adding complexity to the case.
- Jury Trial Timeline: The jury trial is set to begin in March next year, a timeline that may influence Arbutus's stock volatility, prompting investors to closely monitor the case's developments and its potential impact on the company's future.
- Technical Context: The dispute centers on the lipid nanoparticle (LNP) delivery technology developed by Arbutus and Genevant Sciences, which is crucial for preventing mRNA degradation; a favorable ruling for Arbutus could significantly impact Moderna's vaccine production.

About ABUS
Arbutus Biopharma Corporation is a clinical-stage biopharmaceutical company focused on infectious disease. The Company is developing imdusiran (AB-729), its proprietary, conjugated GalNAc, subcutaneously delivered RNAi therapeutic, and AB-101, its proprietary oral PD-L1 inhibitor, for the treatment of chronic hepatitis B (cHBV). Its HBV product pipeline includes Imdusiran and AB-101. Its pipeline includes two product candidates that target various steps in the HBV viral lifecycle and consists of various programs: RNAi therapeutic (imdusiran, AB-729) and Oral PD-L1 Inhibitor (AB-101). RNAi therapeutics utilize a natural pathway within cells to silence genes by eliminating the disease-causing proteins that they code for. PD-L1 inhibitors complement its pipeline of agents and could potentially be a part of a combination therapy for the treatment of HBV by reawakening the immune system.
