You can't put the Apple logo on your product, but you can use it on the website and possibly on the packaging to show it is Apple compatible. The analogy is irrelevent, though, becase CHS have not put the GW logo on their models.
Its the difference between trying to pass off your product as an Apple product and using the trademark to show something is compatible with an Apple product. You are allowed to do the latter, but it won't stop large companies taking smaller companies to court over it totry and use their greater resources to exaust the finances of the smaller company in defending itself. Fact is this case could go either way, it depends how competent CHS' lawyer is and how long the trial lasts.
