A Delaware docket search indicates the patents in question are US 8,069,839 B2 ;US 9,255,519 B2 ;US 9,810,166 B2 ;US 10,138,826 B2
The 826 issued end of November, 2018. Independent claims 12, 21, and 31 are for dual injection system engines.
Given that Bloomberg indicate only infringement of one patent, I speculate that is the 826 patent issued in late 2018. Now that 826 is issued, they are able to pursue.
826 is a continuation filing in the family that starts with 7,314,033. I haven't looked at the family, nor tried to make any appraisal of merit.
Having now looked at the 826 patent, I'm inclined to agree with Animats' comment elsewhere in this thread regarding the claims vs. the specification, which plainly shows two separate fuel systems that hold two different fuel types.
