You’re probably familiar with patents, copyrights, and trademarks, the three main types of intellectual property. Trade dress is the wonky red-headed step-cousin of the family that fills the gaps between the three; you might think of it as a trademark on design elements that trigger consumer recognition. (That’s a vastly simplified explanation, but it’s good enough for our purposes.) Trademarks and trade dress are all about protecting consumers from being deceived in the marketplace — the idea is to clearly indicate the source of a product or service.
It's very interesting that in trademark and trade dress the issue is whether a product confuses consumers, rather than whether ideas were copied. Does this mean, with respect to these claims, that it's fine to copy product ideas and designs, so long as the product is clearly from a different source and consumers would not confuse it with the original source?
(For patents and copyright claims, it's more clear that it's about the duplication rather than the confusion it may cause.)
Only utility patents protect ideas. No other intellectual property does. It's unfortunate that there aren't stronger penalties for rights-holders who make claims wildly beyond the scope of the licenses they're granted. They cause a lot of confusion and unnecessary animosity toward what are very pro-consumer concepts [1].
