> If it was me, I'd reply with a certified letter explaining your situation as a developer, how much revenue the app has made to date in downloads and ads.
Then this whole exercise is patent troll phishing of app sales information from frightened developers.
It was a slightly facetious response. Either way rewarding bad behaviour by sharing private business information with a patent troll does not seem like a sensible course of action.
Isn't the aim of extortionists pre-trial settlement or realisation that there are easier / more lucrative 'marks', so wouldn't actual patent trial numbers provide little indication of the low-level activity of patent-trolls?
Sharing sufficient information to demonstrate there's no money here seems pretty sensible to me (hey I'm a student doing this part time and the app's only been downloaded 500 times @ 1.99 each and apple keeps 30%... so I've made $700 so far...), but if you want to sue me, go for it :)
1/10 the size of the US, and the awards for infringement are nowhere near as large as the US (no triple damages, no especially favourable venues, etc)... so this is interesting as it happens so rarely. As for the numbers, 48 trials in 2012 sort of addresses the size of the market.
