I was reading this submission last night, and it made me wonder, what are other companies paying for patents?

My company does not compensate for patents. I have worked for other large corporations, which have paid in multiple stages:

1) Patent proposal ($1k if the invention has novelty) 2) Patent filing submission ($2-$3k) 3) Patent issue ($3-$5k)

What does your company do and what do you think of employers that do not compensate for patent submissions?
