When examining whether a claim containing algorithm features or business rules and methods features belongs to a technical scheme, it is necessary to consider all the features recorded in the claim as a whole. If the claim records that the technical problem to be solved adopts the technical means of using the laws of nature, and thus obtains the technical effect in line with the laws of nature, the solution defined in the claim belongs to the technical scheme described in the second paragraph of Article 2 of the Patent Law. For example, if the steps involved in the algorithm in the claim are closely related to the technical problem to be solved, such as the data processed by the algorithm is data with exact technical meaning in the technical field, and the execution of the algorithm can directly reflect the process of solving a technical problem by using natural laws and obtain technical effects, then the solution defined in the claim usually belongs to the technical solution described in Article 2, paragraph 2, of the Patent Law.

6.1.3 Review of novelty and creativity

When examining the novelty of an application for a patent for invention containing algorithmic features or business rules and methods, all the features recorded in the claims should be considered, including both technical features and algorithmic features or business rules and methods.

When creatively examining an application for a patent for invention that contains both technical features and algorithmic features or business rules and methods, the algorithmic features or business rules and methods that are functionally mutually supportive and have an interactive relationship with the technical features should be considered as a whole. "Functionally supporting each other and interacting with each other" means that algorithm features or business rules and method features are closely combined with technical features to form a technical means to solve a technical problem and obtain corresponding technical effects.

For example, if the algorithm in the claim is applied to a specific technical field and can solve specific technical problems, it can be considered that the algorithm features and technical features support each other functionally and have an interactive relationship, and the algorithm features become an integral part of the adopted technical means, and the contribution of the algorithm features to the technical scheme should be considered when conducting creative review.

For another example, if the implementation of the business rules and method features in the claims requires adjustment or improvement of technical means, it can be considered that the business rules and method features and technical features support each other functionally and have an interactive relationship, and the contribution of the business rules and method features to the technical scheme should be considered when conducting creative review.

　　"Title Party" refers to the behavior or people who deliberately attract netizens to click and watch with exaggerated and sensational article titles in the network. Many titles have nothing to do with the content or have little connection. The National Network Information Office, together with relevant departments, has carried out special actions of "headline party" such as rectifying titles and distorting the original intention of news, and formulated and issued the "Regulations on the Standardized Management of Internet News Information Titles (Provisional)".

　　Last week, a survey of 2005 respondents was conducted by the Social Investigation Center of China Youth Newspaper. It showed that 78.7% of the respondents had been cheated by the title party. Exaggerating facts (65.5%), taking things out of context (61.6%) and keeping suspense (49.1%) are the most common "title party" behaviors. 66.0% of the respondents bluntly said that the "headline party" would greatly reduce their recognition of the article and the possibility of forwarding it. 73.8% of the respondents believe that the media industry should abide by news ethics and prohibit deliberate speculation of public opinion "hot spots".

　　Among the respondents, 0.9% were born after 00, 21.2% after 90, 50.4% after 80, 19.8% after 70, 6.1% after 60 and 1.4% after 50.

　　80.5% of the respondents feel that there are many news about the "headline party"

　　Chen Siyu, a graduate student of Xiamen University, once ran a self-media WeChat official account. "On WeChat ‘ Subscription number ’ Page, each WeChat official account can only display the title of a dozen words at most. Whether you can attract users to click through these dozens of words will test the level of the proposed title. " She admits that in order to attract attention and increase the number of clicks, it takes a lot of thought to make a title every time. If it is right, it is an incisive "god title", and if it is wrong, it will become a "title party".

　　“‘ Title Party ’ It can be seen everywhere, and it is even more unusual in Weibo and WeChat. " Wu Xiaoyao, a college student in Henan Province, said, "With ‘ Don’t look at regret ’ ‘ Surprise the secret ’ ‘ The truth turned out to be … … ’ Titles of words such as ‘ are not uncommon, and every time you click in, you find & lsquo; Cheated ’ The ".

　　Wu Xiaoyao found that it is not only entertainment news, but also some current political news. "There was an expert who expounded a point of view on a current political issue, but this point of view has preconditions. Some websites directly take the expert’s opinion as the title, deliberately ignore the preconditions and fuzzy logic, and the result has caused controversy. "

　　In the survey, 78.7% of the respondents had been cheated by the title party. At the same time, 80.5% of the respondents believe that there are many "headline party" news.

　　Zhao Wen (a pseudonym) used to be an online media editor. She admitted that the reading volume of "headline party" articles was indeed significantly higher than other articles.

　　The behavior of "headline party" which exaggerates the facts (65.5%) and takes it out of context (61.6%) is the most common. In addition, there are also suspense (49.1%), stealing concepts (44.7%) and making things out of nothing (41.7%).

　　66.0% of the respondents said that the "headline party" would greatly reduce their recognition of the article and the possibility of forwarding.

　　Among the interviewees, 66.0% said that the "headline party" would greatly reduce their recognition of the article and the possibility of forwarding it, 13.6% would not, and 20.4% would consider it as appropriate.

　　In Zhao Wen’s view, the click-through rate and reading volume of articles are the life of network platform operators. "For online media, news is presented to readers in the form of headlines. There are many WeChat WeChat official account and news clients now. If the title is not attractive enough and the content is wonderful, it is difficult to have a high reading volume. "

　　Qiu Hongfeng, an associate professor at the School of Journalism and Communication, Xiamen University, pointed out that the "headline party" aims to catch the picky and fast-moving audience. "In the past, everyone’s daily contact with information was limited, and an evening paper could not be put down from beginning to end. At that time ‘ Title Party ’ There is no place for it. Now ‘ Title Party ’ What is discovered is often not the news value of the event itself, but the information points that can attract the attention of the audience in the news report, even very marginal information points, are enlarged to attract as many audiences as possible. "

　　Qiu Hongfeng believes that the most serious harm brought by the "headline party" is to dispel the social significance of serious news. Attracting attention in a way that caters to the original needs of the audience may dissolve the ability of the news media to set serious social issues for the public. He also said that some "headline parties" enhanced the controversy of news, "such as an ordinary traffic accident, by emphasizing the perpetrator in the title ‘ Rich second generation ’ The identity of, make it have ‘ Class conflict ’ Framework; Another example is a rape case, the past ‘ Gangster ’ The identification of the suspect is the suspect himself, which may now be highlighted in the title ‘ Cowardly husband ’ , even regard him as ‘ Gangster ’ And tortured. "

　　In the survey, 64.2% of the respondents think that the "headline party" is a marketing gimmick and grandstanding, 54.7% think that the "headline party" is an act of disrespecting readers, and 51.8% think that the "headline party" wastes readers’ reading time. In addition, respondents’ views on the "headline party" include: reducing the popularity of the platform (39.2%), encouraging impetuous and unhealthy trends (37.2%), increasing reading pleasure (13.9%) and the website’s understandable intention to increase traffic (9.0%).

　　73.8% of the respondents believe that the media industry should abide by news ethics and prohibit deliberate speculation on "hot spots" of public opinion.

　　"The title is the reporter’s editor’s in-depth understanding and high refinement of news value." Qiu Hongfeng was engaged in journalism in his early years. He recalled that at that time, the journalism industry was very serious and disciplined in the drafting of headlines, and paid more attention to the accuracy, literariness and artistry of headline words. "The pursuit of news value also prompted reporters to explore the conflict of the event itself." Today’s "title party", he thinks, is the product of information overload but attention scarcity in the network age.

　　In Chen Siyu’s view, the phenomenon of "title party" is also related to the homogeneous information environment. "For the self-media, most of them don’t have the ability to fight with professional media. Generally, after a hot spot appears, they write pushes and explain their opinions. At this time, in addition to spelling information increment and spelling speed, it is the title of the eye. " In addition, Chen Siyu believes that the loose control over online media and self-media, as well as the lack of professionalism and weak sense of social responsibility of practitioners are also important reasons.

　　Qiu Hongfeng suggested managing the "title party" from three aspects. "First of all, we should evaluate ‘ Title Party ’ The social impact, to determine which way is the need for reasonable norms. Secondly, the secondary treatment of the original title when the website reprints news can be used as a governance direction to regulate the reprinting behavior, such as requiring the original news title to be retained when reprinting. In addition, if the original news can be more substantially protected by copyright, then the traditional news media’s own network platforms may attract more views, and these news network platforms may be consistent with the traditional media in the taste and norms of titles. "

　　In order to improve the phenomenon of "headline party", 73.8% of the respondents believe that the media industry should abide by news ethics and prohibit deliberate speculation of public opinion "hot spots"; 62.5% of the respondents believe that media and websites with serious "title party" behavior should be punished; 47.0% of the respondents hope that netizens will refuse to open news that is too sensational and suspected of being a "headline party".

　　Tell everyone a "cold" news, the strongest cold wave since the winter of this year is coming soon! It is predicted that from November 26th to 30th, the cold wave will sweep across China, and the temperature will plummet in most areas.

　　Speaking of the cold wave, many people have memories dominated by it. As the "strongest" cold air, how "cold" is the cold wave? What is the strongest cold wave in history? The reporter interviewed Ye Dianxiu, a senior engineer under research at the National Climate Center and the chief expert of meteorological services at the China Meteorological Bureau, and asked him once and for all.

　　1. What is the standard of cold wave? Is there a difference between the north and the south of China?

　　Cold wave is a kind of cold air and a kind of disastrous weather. According to the national standard of cold air grade in China (GB/T 20484-2017) formulated in 2017, the cold air activity that makes the daily minimum temperature in a certain place lower than or equal to 8℃ within 24 hours, or lower than or equal to 10℃ within 48 hours, or lower than or equal to 12℃ within 72 hours is called cold wave.

　　2. How strong is the "ability" of cold wave cooling?

　　Monitoring shows that the average cooling rate of each cold wave in most parts of China is above 10℃. The average cold wave cooling rate in most parts of Northeast China, Jianghuai, eastern Jianghan, Jiangnan and southern China, as well as most parts of Inner Mongolia and northern Xinjiang can reach 12.℃To 14℃, more than 14℃ in most areas of Guangdong and Guangxi.

　　The maximum cooling range of cold waves in Northeast China, most of North China, most of Northwest China, most of Huanghuai, most of Jianghuai, southern Jiangnan and most of Inner Mongolia and Tibet is above 20℃. Among them, the maximum cooling rate in most parts of Northeast China and Inner Mongolia, northern Xinjiang, northwestern Tibet and southwestern Qinghai can reach 25.℃To 30℃, more than 30℃ in some areas; The maximum cooling range of cold wave in Sichuan basin, most of Yunnan and Hainan is below 15℃, and that in other parts of the country is generally below 15℃℃To 20℃.

　　3. How many cold waves occur on average every year in China?

　　In China, cold waves mostly occur in late autumn, winter and early spring. In the past 30 years (1991-2020), cold waves have occurred 5.4 times a year on average in China.

　　Since 1991, the most frequent cold wave occurred in 2021, with 11 times. Followed by 2009, there were 8 times, and the least number of cold waves was in 2017, only 2 times.

　　4. Where did the cold wave affect our country come from?

　　The cold air affecting China can be roughly divided into the following four paths:

　　① Northwest route: Cold air enters China from the White Sea and Barents Sea west of Xindi Island via Siberia and Mongolia in the west.

　　② Northern route: Cold air enters northern Asia from Kara Sea or Novosibirsk Sea east of Xindi Island, and enters China from north to south via Mongolia.

　　③ Western route: Cold air affects eastern China from west to east in Eurasia south of 50 degrees north latitude via Xinjiang.

　　④ Northeast route: Cold air from the Sea of Okhotsk or eastern Siberia affects the northeast of China.

　　more thanPath,The first three paths are more common, while the last path is less frequent and less intense.

　　5. What are the cold waves with large temperature drop in history?

　　According to the monitoring results of cold air process, since 1991, the top five cold waves with comprehensive cold air intensity in China have appeared on November 4-9, 2021, March 11-14, 2006, March 18-22, 1998, February 14-17, 2020 and April 11-17, 2006.

　　Cold waves often bring a wide range of severe cooling, strong winds and snowfall. Taking the cold wave process from November 4 to 9, 2021 as an example, the land area with the temperature drop exceeding 8℃ is 7.709 million square kilometers, accounting for about 80.3% of the national land area. Among them, there are 1.011 million square kilometers whose temperature drop exceeds 16℃.

　　The daily minimum temperature of 172 national meteorological stations in Xinjiang, Gansu, Qinghai, Ningxia, Shaanxi, Shanxi and other places reached or exceeded the historical extreme value in early November.

　　The daily precipitation of 151 national weather stations in Liaoning, Jilin, Heilongjiang, Inner Mongolia, Hebei, Tianjin, Shanxi, Shandong and other places exceeded the historical extreme in November. There is obvious snow in many places in the north, and the depth of snow in Inner Mongolia, Jilin and Liaoning is more than 40 cm.

　　6. Where is the place most favored by the cold wave in China?

　　In China, the frequency of cold wave is characterized by more in the north and less in the south. The areas most favored by cold waves include: Northeast China, western and northern parts of North China, northern and central parts of Northwest China, most of Tibet, Inner Mongolia and other places, with an average annual cold wave frequency of more than 4 times. Among them, there are generally 10 to 15 times in the eastern and northern parts of Northeast China, most of Inner Mongolia and parts of northern Xinjiang, and there are more than 15 times in some areas.

　　7. In cold winter, are there more cold waves than in warm winter?

　　The answer is no.

　　There are obvious differences in judging factors and time periods between cold winter and cold wave, and the annual cumulative cold wave frequency is not necessarily related to cold and warm winter. Cold winter is a kind of climate concept based on the temperature condition of the whole winter, and the basic element of judging cold and warm winter is the average temperature of winter (December to February) for three months. The basic factors to judge the cold wave process are the daily minimum temperature (≤4℃) and the 24-hour (or 48-hour, 72-hour) cooling range (≥8℃, 10℃ or 12℃).

　　Therefore, the number of cold waves in cold winter is not necessarily more than that in warm winter. For example, both 1998 and 2019 were strong warm winters, and the number of cold waves was 6, which was more than that of strong cold winters in 1983 (3 times), 1984 (2 times) and 1985 (2 times).

　　WHO official: There will be a secondary infection in COVID-19.

　　The intensity and duration of human immune response have not yet been determined.

　　Recently, many places reported cases of secondary infection in rehabilitation patients in COVID-19. On 26th local time, Kokhov, technical director of WHO’s health emergency project, said that both asymptomatic infected patients and severe patients will have immune response after being infected with Covid-19, but the intensity and duration are not fully understood.

　　It pointed out that, based on the research experience of other human coronaviruses, it is indeed possible to infect Covid-19 for the second time, and there may be other undiscovered cases of secondary infection, but it does not necessarily happen frequently.

　　Kokhov stressed that the existing tools can avoid infecting Covid-19, such as keeping your body at a distance and wearing a mask. Even if you have been infected with Covid-19, you should still take these measures. This is a new normal life and will continue for some time.

　　Outbreaks occurred in colleges and universities in at least 24 States after the start of school in the United States.

　　Cdc downplays the importance of virus detection, which leads to dissatisfaction.

　　In the United States, where the epidemic is the most serious, the cumulative number of confirmed cases has exceeded 5.82 million and the number of deaths has reached nearly 180,000. At present, many universities in the United States have started school, and the spread of the epidemic on campus is not optimistic.

　　As of the 25th local time, since students returned to school, colleges and universities in at least 24 states in the United States have reported relevant cases, and the cumulative number of confirmed cases of college students and faculty has exceeded 3,300, which has brought no small challenge to the resumption of classes and epidemic prevention and control in the United States.

　　Among them, the University of Alabama has reported more than 500 confirmed cases of COVID-19 since 19th, and school officials said that the growth rate of confirmed cases in the university has reached an "unacceptable level". At present, the university has announced that social gatherings are prohibited inside and outside the school, and those who violate relevant regulations will be punished.

　　In addition, the University of Southern California said that just after the first week of school in autumn, there was an "amazing increase" in the number of infected people in our school. Since the 10th, 90 students and 10 faculty members have been infected with Covid-19. Only one week after the opening of Iowa State University, 130 people tested positive for the virus. Texas A&M University also reported more than 400 confirmed cases.

　　With the outbreak in many universities in the United States, many universities have been forced to resume online teaching. However, when the epidemic situation is so severe, the US Centers for Disease Control and Prevention (CDC) revised its COVID-19 guidelines on 26th local time, and the revised guidelines played down the importance of Covid-19 testing for people without symptoms.

　　In this regard, New York Governor Cuomo said that "the latest guidelines of CDC are essentially self-contradictory, which is completely contrary to what he said before". He also said that "updating the guidelines is for political purposes" and that New York State will not follow the latest guidelines. New York State Health Commissioner Zach also revealed, "I have talked with CDC scientists, and they said that this change is related to politics."
