199 1 has been published, but the inventor has not received the certificate or paid the fee. Is this patent still valid? This is an emergency!

It has long been invalid.

If the license fee is not paid within three months, the applicant shall be deemed to have waived the patent right.

Supplement: 1. Because this technology has been made public, others cannot apply for a patent.

2. Patent is a kind of intellectual property. You gave up the patent right, so it doesn't belong to the inventor.

This technology has entered the public domain, and others' production is not infringement.
