A, B and C all have their own patents for new utility models. A's patent is the earliest. Is there a patent after B Benson is invalidated by B? copy ...

According to Article 47 of the Patent Law, if a patent is judged to be completely invalid in the invalidation procedure and the judgment finally takes effect, the patent is deemed to have never existed, that is, it does not enjoy the patent right from beginning to end.

Therefore, if A's patent is invalid, it is regarded as never having a patent.

B's own patent has nothing to do with this, as long as it is still valid, it is still protected by law.

The production of products with original patent A is not infringing, but the production of products with patent B may be infringing.
