This sort of question only ever seems to come from technical employees, who tend not to interact with customers much. Sales guys -- the good ones at least -- come up with new ideas all the time, and see that as part of their job. You should too.
If you want part of the profits from your ideas, then you need to start your own business and develop those ideas yourself, outside the security of a 9-5 pay check.
I've seen plenty of hawks that just circle and take credit for other people's ideas and hard work. They sprinkle their bullshit on top and then claim credit for it.
