@thumper - there's time windows for each step of the lawsuit process - essentially this process could take one to three years depending on a number of factors.
The next step is for WLLW to file a statement of defense, likely either taking one of two courses: Making their case for non-infringement, or invalidity.
That patent application seems to indicate that WLLW is using iterative evolution and mRNA to modify the host cell organism to produce more of a particular molecule given various enzymes.
It looks like Aurora is on a fishing expedition - hilarious that the patent disclosure came out after they filed their statement of claim - could have saved themselves a bit of cash had they known WLLWs method in advance of filing.
