If there are 5 technical features in a certain claim and only 4 technical solutions are adopted by others, the others cannot be held accountable for infringement. If someone else uses only 4 technical features to achieve the technical effects of 5 technical features in your patent, it proves that the writing level of this claim is not high. If it was originally written by a patent agent, it proves that you have found a claim that is not high-level. What kind of patent attorney? Of course, you may have written it yourself. Now that you are authorized, you cannot sue others for infringement. This proves how important it is to find a professional patent attorney to write claims for you.
