It's all getting too much...
Some patent lawsuits are no doubt valid:- Goliath shouldn't steal from David - OR vice versa.
Others are purely trolling and without any merit - judgements in the good ol' Lone Star State being particularly suspect.
Unfortunately the rest of us are heartily sick of these as many appear to be a variant of playground squabbles and if all of the time and cash thrown in their direction was instead invested in R&D, we could have more competition and improving products, whether it's Samsung, Apple, Microsoft or even old MacDonald producing them.
Innovators must have protection from the rapacious sharks, but Patent Lawyers are usually the most rapacious and shark-like. There must be a better way.
