Don't fighters have intellectual property rights or patents?

..... OK ... I haven't found the so-called overseas prototype of J/KOOC-0//KOOC-0/,but J/KOOC-0//KOOC-0/is actually a winger, but China has also been authorized by Su Huoyi to produce it.

As for the property rights of soldiers, I can tell you clearly that there are. All commercial activities that use the technology used in fighters or the shape of fighters need to be authorized by the relevant enterprises or institutions that develop fighters. Including civil aspects such as models. Look at Tamiya's or Hasegawa's airplane models. The words XXXXX authorized appear on the packaging edge. My Hasegawa F- 15E model has Boeing authorized logo on the packaging edge. Because Eagle Strike was developed by Boeing, it was authorized by Boeing.
