RISC-V benefits is mostly an open source license that is free of patents. I think the biggest reason for it is academic... there needs to be an open platform for academic research. I'm sure it is next to impossible for an average university to do that on ARM or x86 architecture.

- nabla9 9y agoRISC-V is just ISA. I don't think ISA's can be patented. Just some specific instructions.
- pkaye 9y agoYes, they did the research for prior art to make sure that is the case for their instruction set.
- kindfellow92 9y agoISAs can be patented. Intel is patenting their latest AVX/SSE instructions.
- hajile 9y agoISA spec is copyrighted. Instructions aren't patented directly. Instead, the best ways of implementing them are patented.
- kindfellow92 9y agoSeems like Microsoft is potentially being targeted for writing an x86 emulator https://newsroom.intel.com/editorials/x86-approaching-40-still-going-strong/?cid=em-elq-27099&utm_source=elq&utm_medium=email&utm_campaign=27099&elq_cid=1494159 https://newsroom.intel.com/editorials/x86-approaching-40-sti...
