That's not the reason, TLS-SRP isn't that annoyingly encumbered, and even the 
totally unencumbered TLS-PSK doesn't get used by anyone.  I was told a reason 
for the lack of use of strong password protocols from one browser vendor that 
was so stunningly stupid that I had trouble beliving that it was for real, ask 
me in private mail if you want the details.  In any case though it's not 
patent issues that are leading to non-use.
