Do air cushion shoes have Nike patents?
Nike is the patent owner of air cushion such as Air Zoom, but the technology is varied, and Nike is not the exclusive owner of air cushion.
In the past, many American brands, such as And 1, dada, converse, etc. Air cushion shoes have been produced, and some of them are filled with helium and various gases. But Nike insisted on and developed the air cushion technology, and several other brands gave up for various reasons. So those in China are not infringement.
Why do other brands also have air cushion shoes?
Because Nike's patent has expired.
Nike was the first company to use air cushion. Needless to say, that's because they are close to NASA, and the technology developed by NASA can land on the moon first.
Are other air cushion shoes infringing Nike?
1. Does Nike authorize domestic manufacturers? Competitors grant patents to each other, and manufacturers are reluctant to disclose them. We can't speculate at will.
Second, the patent is done, why don't enterprises exercise the patent right? Nike may have its own considerations. Take Tesla for example. His electric car has many patents and mature technology, but the market in this world is not mature. The car he built is awesome, but it can't be sold. As a result, they made a decision to open patents, and any manufacturer can use their technology to grow together and replace the market position of gasoline vehicles.
Third, the administrative department of the market has no law enforcement power. The industrial and commercial bureau suddenly went to the enterprise to check to see if the enterprise infringed others' patents. This is the wishful thinking of many people. This is illegal.
How to clean air cushion shoes?
