Imagine this: you’ve designed a self-buttering toaster, an ingenious invention that can butter 100 slices of bread in 30 seconds flat. Everyone from chefs to sandwich makers and lunchbox-packing parents will love it; the gizmo is set to revolutionise kitchens across the globe. But how do you stop others from cashing in on your idea by building an identical device?
You patent it, of course.
