It's actually worse than that because the "mutually assured destruction" defense only works against companies that can actually be sued. Defensive patents are no help against patent trolls that can't be sued because they're simply not producing anything.
because the mechanisms that reward innovation and development - rents and litigation to collect said rents - are also mechanisms of abuse, we are stuck.
worse, the current system is heavily slanted towards bigness - it is very costly to get a patent, very costly to prosecute one, etc. so large parties employ drawn-out costly defence in depth schemes.
Oh look. Government-granted monopolies lead to hugely inefficient rent-seeking. I think Tyler may be wrong about there not being many low-hanging fruits. Dump or severely restrict both patents and copyright and you will see an almost immediate productivity boost.
