I don't know who needs to hear this, but California Labor Code 2870 says your employer doesn't have rights over work you do that (1) doesn't relate to your employer's business and (2) didn't result from work you did for your employer.

So even if your employment contract uses language that makes it seem like your employer owns everything you make while you're employed, work you do that qualifies under this code will be protected.
