The patent procedure consists of two parts: a) patent application and approval; B) court evaluation and ruling. When you get the patent certificate, it only means that your patent application has been successfully approved and registered, and the actual patent value is not protected by the patent certificate. In fact, the patent certificate itself has no value.
The actual value of a patent must be evaluated and decided by the court, or evaluated by a completely independent evaluation agency through the court.
Patent value audit has a complete system, including legal and technical aspects, which is fully reflected in the structural details of claims and the professional structure of instructions.
A strong patent application must consider both the patent application requirements (stipulated by the patent office) and the patent value requirements (stipulated by the court).
Otherwise, a simple patent certificate is just a junk patent certificate.
These are all comprehensive systems of American patents. In our country (China), due to the late start of intellectual property rights, we only have the Patent Office (responsible for issuing certificates), and there is no complete patent court value evaluation system, so it is impossible to evaluate the value of a patent.
The same is true of PCT, which is only an international patent application procedure for general UN agency projects, and is not responsible for any other functions. Because PCT involves different procedures and requirements in different countries, after many translations and transformations, the connotation of patents has changed greatly, and many patents have lost their protection after constant translation distortion.
Therefore, more than 95% of PCT patents have lost their protection and become junk patents. In particular, domestic patent offices and agencies simply don't understand the international patent value evaluation system and never participate in the rule-making system of the international value system, which makes the proportion of junk patents rise continuously. Personally, I think PCT patent is almost useless!
In the field of ICT (information and communication technology), I still advise inventors that it is enough to really hold the American market, and never think about liberating all mankind, otherwise they will not be able to keep themselves in the end. What's more, the American patent itself is also international to some extent.
To apply for an American patent, you must apply separately in the United States, and never go through the PCT procedure. This is a lesson of blood!
The value protection of PCT is very poor, which is only applicable to large companies that need a lot of patents (rather than patent value), and certainly not applicable to small companies, universities and individual inventors.
Many domestic university professors apply for PCT according to national requirements. As a result, the whole ship sank, and all patents were abandoned because they could not afford the follow-up fees. Moreover, PCT patents are unlikely to have good value, because local courts don't like PCT very much, especially in developed countries.
