I absolutely agree with you in principle. The language in question does not capture inventions you create on your own time with your own equipment, etc, as a matter of law. Copyright may be somewhat different but would need to view the entire contract -- a good one would include a carve-out for inventions, copyrighted works, etc., outside the scope of employment. This is typically where an employee should focus negotiating efforts -- not on the standard risk-allocating language, but on the carve-out. Personally I would never sign a noncompete, and I would never sign an invention assignment agreement except in a limited circumstance such as pledging a bit of software to a foundation to better enforce the licensing terms, that kind of thing. But then I am not ever going to be employed by a large tech company and have the luxury of my personal rules.
