It shouldn't need to be like that but it is the case.
It has nothing to do with the merits of the case itself the tactic a company like Google employs is to just file reams of paperwork, discovery, delays, motion for this and that and each of them have to be considered and discussed and pushes thibgs out at least another day or two. They then use this tactic to extend cases into years.
Although a lawyer will work for a certain cut of the reward they need to eat in the meantime and won't because the case isn't being completed, and isn't going to trial, plus it eats up an enormous amount of time and effort for the lawyer involved cutting into other potential cases.
Eventually you have to call it quits and Google wins because the case never went to trial because Googles legal army was able to delay everything by abusing the legal system.
In short as the PHB from Dilbert once said "we're using the law to keep justice away."
That's what's happening right now.
