Moderna was hit with a new patent lawsuit on Wednesday in Delaware federal court from Northwestern University, which accused the company of misusing the school's innovations to develop its blockbuster COVID-19 vaccine Spikevax.

A British drugmaker, GlaxoSmithKline (GSK), has sued American pharmaceutical company Moderna claiming it violated patent rights in its mRNA technology used to develop its COVID-19 and RSV vaccines.

The Mandl team was originally employed by Novartis, but GSK acquired rights to their work and intellectual property when it acquired Novartis' global vaccine business in 2015. Only by tapping into this earlier work was Moderna able to bring its mRNA vaccines to market so swiftly, the suits claim.

Nearly six months after lodging a similar complaint against Pfizer and BioNTech over the partners’ COVID shot Comirnaty, GSK is targeting Moderna in a pair of lawsuits alleging the Massachusetts-ba | GSK is targeting Moderna in a pair of lawsuits claiming the mRNA specialist violated multiple patents with its vaccines Spikevax and mRESVIA.

Moderna Inc.’s shots for Covid-19 and respiratory syncytial virus infringe as many as seven GSK Plc patents related to mRNA vaccine-delivery technology, the company said in a pair of federal lawsuits.

GlaxoSmithKline has filed lawsuits against Moderna in a Delaware federal court, alleging infringement of patents related to mRNA technology in Moderna's COVID-19 vaccine Spikevax and RSV shot mResvia.

The lawsuits claim that Moderna used and profited from crucial mRNA technology in its COVID-19 vaccine Spikevax and respiratory syncytial virus shot mResvia.

GlaxoSmithKline sued Moderna in Delaware federal court on Tuesday for allegedly violating GSK's patent rights in messenger RNA (mRNA) technology with its blockbuster COVID-19 vaccine Spikevax. The lawsuit said Moderna's lipid nanoparticles for transporting mRNA into the human body infringe several GSK patents covering similar innovations.

GSK filed two lawsuits at the US District of Delaware on 15 October saying that Moderna’s mRNA vaccine product Spikevax infringed up to seven patents covering lipid mRNA vaccine formulation technology. It is also suing Moderna for infringing the same mRNA technology through the sale of its recently approved RSV shot mResvia.

GlaxoSmithKline is suing Moderna for allegedly using technology patented by GSK in its COVID-19 vaccine. Why it matters: It's the latest in a series of legal fights over who owns the intellectual property behind mRNA technology and whether some companies are entitled to royalties on future sales.
