A good example of this is the  4-input LUT-based FPGA. Originally, this was
an idea that Xilinx implimented. Later, Altera came up with their own FPGA 
that also was a 4-input LUT FPGA. Xilinx sued Altera for patent infringement. 
Altera payed $20 Million USD to Xilinix and agreed to call thier 4-input 
LUT-based FPGAs CPLDs.

The corporate perspective is that $20 Millon USD changed hands. From a design 
standpoint, the outcome changed the nomenclature of two identical 
technologies.
