Granted to any new process (method of injecting snack cake filling), machine (snack cake oven), article of manufacture (anything that's made by a machine-the snack cake itself), composition of matter (snack cake preservative), or new/useful improvement (to anything, not just snack cakes).

Granted to any new variety of plant not produced from seeds. Wait, no seeds? Yep. New plants can be created by grafting, budding, cutting, layering, or division.

Any new, original, or ornamental design for an article of manufacture. A snowboard model, for example.
