Yes, but does it say "in the course of your employment"? The "whether or not during working hours/using company's equipment" part just covers the case where you are working late, etc. If your contract contains the phrase "in the course of your employment", then you can still work on a hobby project and it remains yours, because you didn't work on the hobby project "in the course of your employment" (you were not asked to build the hobby project)
