I think perhaps there are two reasons for this: 1. The patent protection frightens potential users away. The fact that a license fee needs to be paid to use the system eats into profits. Here where RSA is not patented (probably due to the prior publication rule for European patents), it is more widely used. Though still not incredibly popular. 2. It is slow! A decent private key algorithm can be used to encrypt bulk data much quicker. That means PK algorithms are limited to message authentication and key exchange.
