The EVERY Co and Onego Bio were discussing a potential merger valued at $400m before negotiations broke down.
According to court documents, the two companies, which specialize in alternative egg products, were in talks to create a new company before Onego Bio sued its rival.
The lawsuit, filed by Onego Bio, seeks to invalidate one of The EVERY Co's patents related to the production of ovalbumin, a protein found in egg whites, via precision fermentation.
The dispute centers on whether Onego is infringing a “foundational” patent from The EVERY Co covering ovalbumin expression in a range of hosts.
The EVERY Co has urged a court in Wisconsin to dismiss the lawsuit.
Author's summary: The EVERY Co and Onego Bio's merger talks failed.
