That Aerotel patent again -- has it fallen?

A little bird has told the IPKat that the famously controversial Aerotel patent for a telephone system in the UK (see earlier posts here, here , here and here) was revoked earlier this week. Rumour has it that the patent was considered to fall within the non-patentable subject matter under Article 52 of the European Patent Convention and, for good measure, also to have been lacking in inventive step.

Right: the IPKat is all ears ...

Not having seen any corroborative evidence, the Kat wonders if his readers can provide any further detail -- preferably traceable to a reliable source.
