According to statistics, for every 100 ideas produced by inventors, only 20 to 30 % can be made into actual products. Of these, only about 10 % are ever mass produced and commercialized. After commercialization, less than 10 % likely ever appeal to consumers and earn large profits. These facts show that the path from initial idea to successful product is long and difficult.
據國內外統計，發明人的一百個創想裡，只有二到三成可以真正被製出實品；其中又只有一成會被量產、商品化；商品化後能獲得消費者青睞而賺大錢的，大概又不到一成，可見得發明之路多麼漫長艱辛。
