New ideas that are valuable to the market are by definition worth rewarding so that more of them get created.
Some valuable ideas, however, have difficulty translating release into reward simply because despite their originality and value to society, they are easily copied.
This creates a problem for everyone. Something we all benefit from encouraging, and that pays for itself (in terms of value that it creates), is being disincentivized.
To overcome this hurdle, and achieve a higher economic maxima for both creators and consumers, we have limited (in scope and time) protections for different kinds of valuable but easily copied ideas: patents, trademarks, trade secret, and copyright.
Any situation where valuable creations are being disincentivized, is worth consideration of whether that situation could be changed to everyone's benefit.
