Patent on Wireless Transfer of Pupil Data

hjayres writes: "London based Company Bromcom has a patent on 'wireless pupil data transfer' and is suing companies they feel have broken this patent. If a school wants to use the government grants available to reduce truancy by wireless linking pupil attendance records on PDAs and handhelds have to first pay Bromcom for the licence. Is this potentially more damaging than BT's Hyperlink scam? This also includes open source Learning Management Systems that are used over Wireless. The Patent applies in the USA."
