Why are most patents useless?

Just because you don't use it now doesn't mean you won't use it in the future. For a company or an individual, owning a patent is never a bad thing, just like why Nokia still lives on its previous patent. Apple lost more than $2 billion to Nokia before.

The advantages of applying for a patent are:

1. Protect your product or method from being infringed by others.

2. Putting the patent number on the product is a very good advertising function.

3. Having patent autonomy is an important condition for certifying the qualifications of enterprises, such as high-tech enterprises.

Applying for a patent is also an affirmation of the inventor's knowledge, which is good for him to evaluate his professional title in the future.
