Funny story, in my old "job", I at times helped the lawyers (who often needed help). Part of that was reading briefs from our side and then their side. Almost every time, I'd read out brief and say "We have them locked down here." and then I'd read their rebuttal and think "We're toast."
It was fascinating to me how the lawyers could bring up these somewhat obscure points to help their cause effectively.
My actual input was only technical, not legal, so I didn't have to weigh in on the legalities of it all.
Fortunately. One lawyer we had billed 20 hours per day, and everyone said "He really does work 20 hours a day." At a grand per, 20 years ago.
I never met him, wanted to.
