The world needs to move on to elliptic curve cryptography.
Trouble is the company that owns Blackberry holds patents on ECC.

I would think that the patents would be soon to expire. Remember they only patent for 20 years. ECC has been around since at least the end of the 90’s, it can’t have much longer if it hasn’t already gone out of patent.
The wonderful article you linked to is from 1999 and reflects the patents of that time. We are four years beyond that and likely some of the patents have expired. I can’t imagine the most significant of them having more than maybe two or three years left.
