How to check whether the articles published in magazines have applied for relevant patents?

First of all, we should determine the technical scheme in the documents in the magazine, and then search China National Intellectual Property Administration's websites or some patent search websites according to the contents or keywords in the technical scheme, and analyze whether the searched related patent documents are the same or similar to the technical contents of articles published in the magazine. If they are the same, it means that we have applied for a patent. Generally speaking, the same patented technical solutions are less, and more are similar technical solutions.
