1. Because there are many patents with a similarity of more than 90%. If someone else makes a slight change, it will be a "new" patent! ! !
1. A slight change, if it is really simple and is equivalent in official language, then even if such a change applies for a patent and obtains the patent right, it will still be invalid and it will still infringe your rights. patent.
2. Secondly, if the modification is not very simple and does not belong to equivalent means, then other people's patented improvements are also labor-intensive creations. Otherwise, why didn't you think of it at the beginning? If you thought of it, why didn't you write it? Enter the scope of protection or generalize it into your scope of protection.
So your above views only show that your understanding of patents is not deep enough.
2. If there is an infringement issue, there is no partial infringement. This is a headache. Seniors who are still busy working on patents would like to ask, are patents really useful? ! !
1. It depends on the angle. If your patent is A and the other party’s technology is A+B, then the other party has infringed on your patent rights, which can also be regarded as a partial infringement.
2. If your patent is A+B and the other party’s technology is A, this concession does not infringe on your patent rights. You are clearly protecting A+B as a whole. If you had originally I think A is also a good independent solution, so why don't you write it as a patent right? Otherwise, the dispute will be judged based on the factual criterion after the fact.
3. Of course, the judgment of patent infringement is not as rigid as doing arithmetic problems. Judges are not all robots who only follow the law. For example, according to the situation of 2, if B is a The auxiliary part, and the other party deletes the auxiliary part of B to obtain product A, and the effect is obviously reversed. At this time, it can still be considered as an infringement of your patent rights, because the other party is obviously making modifications to circumvent the implementation of your patent.
To sum up, the reason why you have these extreme views is because you are not familiar with patent law.
Of course, no legislation is perfect, and it is expected to become increasingly perfect as the times progress.
