4on4off, even though you've probably already educated yourself on the following, I thought I would post this just to give you some guidance on the "business purposes' of the VPLM patent. Some still don't understand it:
the routing, BILLING, and rating of all cell VOIP traffic, which is the current legal battle VP is in with apple,att, etc..:
US8542815 (B2) 2013-09-24 (Routing, billing, rating technology)
US8774378 (B2) 2014-07-08 (Routing, billing, rating technology)
US9137385 (B2) 2015-09-15 (Routing, billing, rating technology)
US9179005 (B2) 2015-11-03 (Routing, billing, rating technology)
US9537762 (B2) 2017-01-03 (Routing, billing, rating technology)
US9813330 (B2) 2017-11-07 (Routing, billing, rating technology)
US9826002 (B2) 2017-11-21 (Routing, billing, rating technology)
US9935872 (B2) 2018-04-03 (Routing, billing, rating technology)
US9948549 (B2) 2018-04-17 (Routing, billing, rating technology)
US9998363 (B2) 2018-06-12 (Routing, billing, rating technology)
US10218606 (B2) 2019-02-26 (Routing, billing, rating technology)
You know when you're on a voip wi-fi call and then you leave that particular wi-fi connections' range, but for some reason you don't lose you call? Well, VPLM owns the patent for that:
US8630234 (B2) 2014-01-14 (Mobile gateway technology)
US8675566 (B2) 2014-03-18 (Uninterrupted transmission technology)
US9154417 (B2) 2015-10-06 (Uninterrupted transmission technology)
US10021729 (B2) 2018-07-10 (Uninterrupted transmission technology)
Here's another one. Lets say you're on a voip cell call and you need to dial 911; how do you think that call is handled to get your location? Well, VPLM owns that patent too:
US8537805 (B2) 2013-09-17 (Emergency assistance calling technology)
US9565307 (B2) 2017-02-07 (Emergency assistance calling technology)
Or better yet, lets say law enforcement needs to tap a voip cell call. well, vplm owns those patent too:
US8422507 (B2) 2013-04-16 (Lawful intercept technology)
US9143608 (B2) 2015-09-22 (Lawful intercept technology)
US9549071 (B2) 2017-01-17 (Lawful intercept technology)
US10038779 (B2) 2018-07-31 (Lawful intercept technology)
