Motorola, and HTC to some extent, are companies that were on their last legs, almost bankrupt, and the world's most profitable tech company, with half the market, and $150 billion in cash, is engaged in offensive lawsuits against them trying to enact import bans. Who is the bully here? It's like a billionaire punching a street bum in the face, and then whining when the bum fights back ungentlemanly. The two biggest bullies, Apple and Microsoft, have cross-licensing agreements and a behavior of ganging up on Android.
I find it absurd that FRAND patents are practically valueless, but "obvious" patents, which are effectively standards essential because wide applicability, are worth billions and import bans. Apple sued HTC over a patent which is a college algorithms homework question, the first strike on the Android was launched by Apple in 2010. I would view all suits against Apple since then, not as trolling, but as an attempt to negotiate a cross-license by forcing them to the table.
