Lights come on, lights go off. You could patent the exact timing/sequence of that, but change it by 1 millisecond or one color variation and the patent is void. Vanilla Ice proved that, changed 1 note in the Queen song Under Pressure invalidated Queen's patent as now its an entirely different pattern, regardless of any implied/assumed similarities. TT patented the Riing, it's particular design and composition. Not it's ability. Add or remove 1 led, change the wiring path, the design of the snaps used to hold the clear ish plastic and it's now no longer a Riing, even if it looks identical from the outside. It's why you cannot patent a PSU, only the platform, the design. Not the fact of a power supply. Same as the effect of plugging in a connector is universal, you could patent the exact molex connector in the back of the psu, but not the modularity or its aspect or permutations.
