When will Nike’s air cushion patent expire?

Nike was the first to use air cushions. Needless to say, this is because they are relatively close to NASA. The technology developed by NASA can be first to gain ground (of course, the real situation is said to be that of NASA) The engineers who invented Air found adidas first, but Adi ignored them. Adidas in the 1980s was much better than Nike).

adi also launched air-cushion shoes, which was earlier than other brands, probably in the 1990s.

Then came and1. I can’t remember the name of the technology that starts from the left and right sides of and1’s air-cushion shoes and is concave in the middle.

Li Ning has also launched Airbags, but there are not many styles.

Some American skateboard shoes such as DG have also launched skateboard shoes with a starting point.

There are too many domestic small brands to guard against, so I won’t go into details.

The patent for air expired in 2002 (it seems to be around 2003 or 2000), so Nike launched airmax 360 to commemorate this cross-century technology. With the expiration of the patent, many brands can use this patented technology (at least in the United States)

But unfortunately, due to the need for brand differentiation, other brands have not made air cushions a technology Be mainstream.

Adi is often the first to launch the next generation of technology. The Tianzu technology in the 1990s, the No. 1 shoe electronic technology in the new century, and the subsequent ground control formotion technology are actually all technologies that are ahead of the present. It's a pity that Europeans are much less concerned about technology and marketing than Americans. No, Reebok AND1 also has similar air cushion technology, but NIKE’s is the most powerful
