I got one patent while I was a Qualcomm for some fairly inconsequential software thing. I was awarded $3k USD. Had the patent been filed in other countries and awarded, I would have been awarded I think 1.5k USD per country. This is/was the standard deal at Qualcomm when I was there (2013-2021). I would not be surprised if core researchers are awarded more for stronger and more applicable patents.
Seems like the message behind 'this is core to our business' is easily communicated with financial incentives backing that up.
