What are Carpenter Tam s 81 patents?

This question is more complicated, in a few words, I can only give you a rough idea, the specific judgment method is not engaged in this industry you will not understand for a while, good to get to the point.

There are two major principles for determining patent infringement, one is the principle of comprehensive coverage, and the other is the principle of equivalenceThe principle of comprehensive coverage means that all the technical features of your patent rights must cover the infringing material involved in the case, and none of them are indispensable, and none of them will not infringe.

2.The principle of equivalence, due to the breadth and depth of Chinese and the similarity of the physical and chemical properties of some characteristics, it is a bit arbitrary to completely use the principle of comprehensive coverage, so the principle of equivalence is introduced, which means that the technical characteristics of the invention patent are similar to the characteristics of the product in question, and the guest is determined to be equivalent, for example, the material recorded in the invention is iron, and the product involved in the case is steel, which can be recognized as the principle of equivalence, but the principle of equivalence is now gradually restricted from use, Some experts believe that the principle of equivalence can only be applied to the prior art features in the technical features, and the core invention point of the present invention cannot use the principle of equivalent.

In addition, there is also the principle of estoppel and the principle of donation, which are all niche concepts and will not be repeated. In the practice of determining patent infringement, it is still easy to judge the product invention, because it is possible to disassemble the specific structural parts and compare them with the technical features of the invention, but it is more tricky to the method invention, such as when the invention records factors such as air pressure, temperature, reaction time, etc., it is not easy to determine the specific value of these parameters in the technology involved, and it is also very difficult to preserve the evidence. There are no less than 50 patent infringement cases, and if necessary, you can directly consult on a case-by-case basis.
