A company that says it is developing a potential COVID-19 vaccine has asked for court action that would require a DNA manufacturing firm to divulge proprietary techniques in the hopes of ramping up production of a drug that could end the pandemic, but a Pennsylvania trial court judge has denied that request.

Judge Jeffrey Saltz of the Montgomery County Court of Common Pleas on Thursday denied a request for injunction that Plymouth Meeting-based drugmaker Inovio sought that would have compelled South Korean DNA manufacturer VGXI to transfer proprietary manufacturing processes to as many as 10 other manufacturers.
