Based on my background I'm going to take my best guess on what happened here.
Citro Tech either came very close to Break’s technology or, in the worst case, was trying to capitalize on Break’s actual product without their approval. Break found out about the product and threatened a lawsuit. The attorneys then warned Citro about the ongoing legal costs and the years it could take to resolve, with the risk of having it hang over a company whose only product is its fire protection. In other words, a court ruling in Break’s favor could put Citro out of business.
On the other hand, Break would likely face over $1M in legal fees and a lengthy 2-to-3-year court battle just to prove their claim. Coming up with that kind of money would be tough, and the process would drain significant time and energy from the company, especially when they might have more productive ways to generate revenue. IE. Winner should they still be in play at this hour.
We will have a better understanding of just how valuable the buy out of the fire protection was and why Break is closing this so quickly.
Again, just thinking out loud here.
