It was also defended: its inventor should be able to earn something from his invention while it was new, before it was widely copied as seen before with the kaleidoscope. [5] Paris later claimed he gained £150,- from its sales in the United Kingdom. [4] As expected, pirate copies soon became common and were much cheaper.
