Casio CZ/ VZ/ FZ - Pro Series

I got this from a web site and I was reading: Unfortunately YAMAHA sued CASIO, stating that PD violated their patent of FM synthesis. YAMAHA won at last. 
CASIO retreated from the synthesizer market. CTK-1000 was released soon after that. In contrast to CZ and VZ, this time CASIO carefully avoided to disclose what IXA's Nonlinear means. 

So what are your thoughts to this?
