Oh man. not more bloody IP
Protracted IP battles must be costing the industry billions. No wonder they can't afford to pay their contractors anymore. It's all such crap.
I'm thinking that as a solicitor's letter cost anywhere between £50 and £2,000,000. If you sent an email to every company you could think of claiming to be in the process of patenting a pen an paper based information transfer system which you would licence in perpetuity for £40. They might as well settle rather than involve the legal dept. Quids in!
