I am trying to get a clearer picture of how companies like ARM manage to stay afloat with just IP/Royalties. Recently ARM licensed some of it's instruction sets to Apple in order to design/build the M1 Chip. Also I have read about improvement grant backs here.
Say Apple came up with some form of next level improvements to what was licensed from ARM would this have meant ARM would have rights to build on the improvements from Apple and be able to license new technologies (based on the improvements) to other companies or clients in the future.
