The company I currently work for sadly claims all IP. Not just the things I do for the company but all IT related stuff I do in my free time and even all non IT related things. I could write cook book and it would belong to them. I tried to get that changed but they were only willing to cede IP rights to non IT related products but will still remain a usage right. At least they are willing to transfer all rights to coworkers or me if we ask them to do so for a private project. But even though they seem willing to grant exemptions I'm put off by such contracts. At the end of the day only the contract matters and good will does not.
