BT claim they own SIP

By Simon Woodhead

Shortly after midnight last night my inbox pinged with a concerned email from a diligent customer. They’d seen news on The Register that BT were claiming ownership of 99 Patents which give it ownership of SIP. The article makes interesting albeit concerning reading. We haven’t yet heard any view from industry sources so wanted to get this out amongst customers.

Whilst recently at Kamailio World in Berlin, on the VUC Panel, a question arose about Patent Trolls. I gave the example of incumbent telcos having drawers full of patents whose scope was unimaginable when they were granted. One specific example I gave was BT having a patent over the hyperlink which seems somewhat ironic now!
