One more benefit of the brexit for mainland Europe! I didn't know about using the WTO to dispute invalide patents. I guess a WTO dispute can make sense for a Boeing software patent used by Airbus. I wonder whether the WTO would care about an independent developer. It's not very good press, but perhaps it's fine for them.
WTO doesn't care, WTO serves as a forum to get it through.
The question is, does a "practicing entity" holding the patent cares enough to go through the hardest route to get the patent executed using WTO as a forum? One needs to compare costs and benefits. It's why patent trolling involved pretty much few counties in Texas, because that's where the costs were lowest compared to benefits.
It's not just the UK that allows software patents in practice - as the discussion hints at, Germany does too, and if I remember rightly pretty much the last patent affecting MP3 was a German patent on zero-padding held by Philips, who enforced it aggressively against manufacturers of devices like music players.
