In the UK, there is an administrative "reexamination" process that is significantly cheaper... only 250 UKP: https://www.gov.uk/government/publications/request-for-opini...

If someone wants to do the work to put together and file the claim, I'll provide the ₤250. Worth it to see attempted patent enforcement destroyed.

		I think this is a great idea. My only concern is, what if some well-meaning person puts in a poorly constructed claim, and then that creates a counterproductive precedent. I think ideally, someone like Software Freedom Conservancy or the Linux Foundation or the FSF or whoever would take charge of doing it, taking advice from patent attorneys in the process. Maybe there is some UK patent attorney reading this who is willing to take it on pro bono?
