4. 1. Possible scope of infringement
the patent law stipulates that the scope of protection of a patent right for invention or utility model shall be subject to the content of the claim, and the description and drawings can be used to explain the content of the claim
the interpretation of the Supreme People's Court on Several Issues concerning the application of law in the trial of patent infringement disputes stipulates that the people's court shall examine all the technical features recorded in the claims claimed by the obligee when deciding whether the infringed technical solution falls within the scope of patent protection, The people's court shall determine that it falls within the scope of patent protection; If, compared with all the technical features recorded in the claims, the technical features of the sued infringing technical scheme lack more than one of the technical features recorded in the claims, or more than one of the technical features are not the same or the same, the people's court shall determine that it does not fall into the scope of protection of the patent right
it can be seen from the above provisions that if a proct is identified as infringement in the patent document, it must cover all the technical features recorded in the claim. Therefore, in order to obtain a larger scope of protection, the less content in the claim, the better, that is, do not add unnecessary content
the innovation of blockchain is usually associated with multiple executors, which is a systematic scheme that needs the cooperation of all parties. For example, if the data publishing node, blockchain network, authorization node, etc. are combined in a claim, it will be found that when the patentee wants to sue an executor for infringement, the party does not cover all the contents of the claim (at least not other executors), which leads to that although the party uses the innovative idea of the patent, it does not infringe. Therefore, in a claim, it is better to write the scope of protection around an executor< According to the patent law, except as otherwise provided in this law, no entity or indivial may exploit its patent without the permission of the patentee, that is, it may not manufacture, use, promise to sell, sell or import its patented procts, or use its patented methods, or use, sell or import its patented procts for proction and business purposes Promise to sell, sell and import the procts directly obtained according to the patented method
here we should pay attention to "for the purpose of proction and operation", that is to say, not for the purpose of implementation, no infringement. Therefore, when writing the claims, we should also consider who the potential infringement objects are, and the content of the patent right should limit them as far as possible, instead of including unnecessary objects (such as the devices used by the end consumers).

In the past 24 hours, more than 110000 people in bitcoin have burst their positions, and 5.8 billion funds have been swallowed. In fact, I think the team is cutting leeks. In fact, the decline of bitcoin can be met in advance, and nothing can prosper all the time, So for most people, they still need to maintain a rational attitude to buy some funds or stocks and bonds. If it becomes a state of large-scale loss, then their money will be tied up, which is certainly not very good for them. Our attitude towards bitcoin is that it will not decline, it will only rise, So most people may not consider this situation and put all their money into it, but in such a situation, if the institutions withdraw their funds, they will inevitably face a lot of capital losses of retail investors

however, in the face of such a situation, we must understand that not all such things can have an answer, such as this kind of irregular things. As an ordinary investor, if we want to buy opportunistically, we may have to bear a greater risk, but in the face of the relative institutional investment, They may take less risk, because the risk they need to take is actually created by them. For most institutions, if they want to go up in the last stock, the probability of the stock's rise may be much greater than the probability of its decline. As for bitcoin, more than 110000 people burst their positions in the past 24 hours and 5.8 billion funds were swallowed, losing money in succession, in fact, I think the team is cutting leeks
