Patent expiration problem

It can be produced, but only if you file an invalid application for that patent with the Patent Office and invalidate the patent he applied for in China, can you legally produce it. You need to find a patent agency to help you handle this matter.

If you apply for a patent abroad, don't grant a patent in China after one year, because the technology is not new. After your invalid application is verified by the Patent Office, its domestic patent right will be revoked.

It's legal to do so, but it's a bit selfish. Test it yourself.
