> Not exactly just minor rewording because you could still be in breach. You need to make major modifications.

Again, only kinda. Techniques, styles, methods, ingredients, timings, quantities are all not covered by your copyright.

A bare-bones recipe would likely not be covered by copyright, as it has nothing in it that is copyrightable. Only when you expound on reasoning of methods, or cautions do you start to get things that can be copyrighted.

> Patenting an innovative recipe is perfectly allowed though, including design patents of the innovative look of the item.

I'm not sure what has given you that idea. Generally speaking, in Australia, a process that creates an edible item, is not patentable. These are set out as non-patentable:

> Capable of being used as a food or medicine and is a simple mixture of known ingredients (section 50(1)(b)(i))

> Is produced by mere admixture (section 50(1)(b)(ii))

Unless the process itself is inventive, and involves techniques out-of-reach of the average person, it probably is not patentable.

However, you can trademark items that are not fit for the patent office, that has a lesser set of requirements.
