Copy Rights to a design being made

[BusyLittleShop]

I hold a aircraft related Design Patent... In general, a Design Patent
protects the appearance of an item regardless of how it works, whereas
a Utility Patent protects the way an item works regardless of what it
looks like... Broadly speaking Copyright can be used for almost any
artistic or written creation... either way I recommend Nolo's book...
be sure to buy the most up to date version due to changes to our laws...
