Is it unreasonable to suspect that a company that has had multiples breaches of security of this extent might also not have had its IP taken out from underneath them as well?
but if the details of a patent have been stolen the patents still have value, except for when the exact implementation of a patent can be circumvented due to access to plans.
They are pretty big assumptions to make.
Second assumption: letting 80% of staff go won't hurt. For that, I simply have to describe what I've heard from friends / coworkers / scuttlebutt about working at yahoo. But there are a lot of eng doing maybe a couple hours of work per day.
