Cathrine Hettinger is not the inventor of the fidget spinner

edit

Scott McCoskery invented the fidget spinner while acting President of MD Engineering LLC. Utility patent 9914063 was issued by the US Patent and Trademark Office in 2018 to MD Engineering LLC and clearly indicates Scott as the inventor. The important distinction between Kathrine's invention and Scott's is the fact that Scott's invention utilizes a bearing in the middle covered by metal, which provides a way for the user to spin the fidget spinner while holding it between their thumb and finger. Cathrine's invention is similar to a hat, which spins on top of your finger rendering it impossible to fidget. Fidgeting a fidget spinner is when the user changes the direction of the spin using the fingers on the same hand in which the user is holding the fidget spinner. — Preceding unsigned comment added by 96.78.56.226 (talk) 00:13, 23 August 2020 (UTC)Reply

Patents are primary sources. Wikipedia prefers secondary sources. We can't read a patent ourselves and draw a conclusion about whether it is fundamental to the idea of a "fidget spinner" or not. All we can conclude from a patent is that such a patent exists, with a certain date of application and grant date. Another interesting patent is Pavelsky's (see Talk:Fidget spinner/Archive 1#Inventor and availability of the fidget spinner as shown on the Wiki.). Since that is a design patent, it does not indicate that Pavelsky invented something fundamentally new, but it demonstrates that the design that he depicted existed and was known to him by November 2016, which is earlier than McCoskery's final patent application (filed in May 2017), although not before McCoskery's provisional patent application (filed in May 2016). —⁠ ⁠BarrelProof (talk) 20:32, 29 September 2023 (UTC)Reply
