This has been pretty typical of my experience, I get a contract that says, basically, they own all things I create during the course of my employment. I offer changes to the subsection, that indicate they own only those things which I create specifically related to the problem spaces+ the company works in, with specific exclusions around any existing creations I have. Usually, in the contracts I've been offered, there has been a specific schedule to fill out for pre-existing invention disclosures. Not once has any company refused such a change. + Worded appropriately, of course.
