Figure 1 indicates by November 31,2004,the number of the patent applications published in china every year from 2002 to 2004,figure 2 indicates the number of domestic application published in every year. in 2002,the accumulated number of domestic applications published is 58 pieces, accounted for 60.4% of the total number of 96.In 2003,domestic patent applications published reached 82 pieces, accounted for 80.4% of the total number of 102, and in 2004, the number of domestic patent applications published increased to 91 pieces ,accounted for 72.2% of the total. The number of domestic applications increases as the number of the total patent applications increased. It is predicted that the patent application titled about dairy product will increase rapidly, just as the consumption increases.

(2) Non-service inventions are majority while service inventions increased year after year

In addition, According to the distribution of applicant, the ratio of service invention is also increased year after year. Table 1 indicates by Novermber 31,2004,the number of domestic service applications every year between 2002 and 2004. As indicated in table 1, the ratio of the number of domestic service patents reached 36.2% of the total applied in China in 2004, increased 22.4% and 23.2% greatly compared with 2002 and 2003. In the other word, the increase of the number of domestic patent applications is due to the patented applied by enterprises、colleges and scientific research institutes.

And if ,according to the distribution of applicant, more and more enterprises、colleges and scientific research institutes began to seek patent protection. In 2002, total 11 applicants of domestic service inventions mostly include Shanghai Bright Dairy & Food Co., Ltd、Beijing Huafangtianyu Biology product Co., Ltd and etc. The number reached 12 in 2003,,new applications are shijiazhuang Sanlu Group Co., Ltd、xilinguole alliance XinTai Biology product Co., Ltd. etc, and in 2004,the number of applicants increased abruptly to 22,new comers include some famous enterprises such as inner mongolia Mengniu Dairy Product Biology product Co., Ltd、JiLin Dairy group Guangze Biology product Co., Ltd, Heilongjiang wandashan Dairy Biology product Co., Ltd、Shanxi Hengkang Dairy Biology product Co., Ltd. More and more enterprises、colleges and scientific research institutes began to pay attention to exploiting and applying for patent. As a result, it will change the status of non-service patent applications are majority while the technology level is low. Many enterprises have take patent application and strategy as an effective weapon to fight for greater success in market competition and development. whereas enterprises、colleges and scientific research institutes should attach more importance to patent in order to change the characteristic of the dominant status that non service patent accounted for majority.

(3) Low technology level of the invention applied

Nestle Co., Ltd of United State is one of the foreign applicants whose application number is enormous. There are 6 pieces of patent applications applied by Nestle Co., Ltd while 4 pieces applied by Shanghai Bright Dairy & Food Co., Ltd in the patent published in 2004,we can realize the distance of the technology level between domestic and foreign industry from comparing above two companies?application in the content, title and IPC of the patent applied. The domestic applications still lay particular stress on formula of products and the displacememt of the raw materials, so the technology field of the patent is more narrow and the number of the foundation patent applications is fewer.

So the direction of the development of the future patent applications must not only attach the attention to the quantity of the patent applied, but also centralize in the improvement of the technology level.


8. Analysis and Forecast on Patent Applications in Photography Area

The photographic technology has experienced development more than 100 years. We are moving into the digital recording era from the past silver salt sensitizing era. Digital camera just went through a dozen of years'development. The patent application on digital camera is increasing in recent years.

Majority of patent applications on photography are foreign applications. The ratio of domestic and foreign applications is severely unbalanced. It is about 1: 9. Applications are centralized in countries such as Japan, the United States, Korea, Germany, etc. while applications from Japan accounted for more than 70%. Most foreign applications are company's service inventions while as the domestic applications are basically non-service inventions. Domestic applications clustered in stereo image and holography area, and foreign applications are basically camera-related. Applications on camera centralized in one-time used camera, APS camera, data recording device, film transfer, photographic lens, digital signal processing, control system, electronic shutter, AF, AE, AWB etc.

Application on one-time-used camera and APS camera probably are a bit more that others in terms of quantity. One-time used camera is characterized as miniaturization and low cost. Miniaturization is performed through reducing volume of parts and optimizing space. Cost could be reduced by reusing some parts of camera, for example, the cost could be reduced by reusing the flash device. Camera fitted with APS film can record not only image, but also information of photographic time and setting. It also allowes picture with different format to be shoot, meanwhile, it can provide data for late printing.

Technology of digital camera has been developing rapidly, now it has tended to be mature. The obvious difference between digital camera and silver camera lies in the sensitive element. Digital camera's sensitive element is image sensor instead of film. CCD is usually used as image sensor. CMOS is likely to replace CCD on some low end product because the index of sensitivity, dynamic range and SNR ect. on CMOS has improved significantly. Digital signal processing is important component on digital camera. Much works on signal processing and calculation need be performed after digital electronic signal is obtained by A/D converting, these works include digital filtering, recombination of image information, data compress etc. In order to obtain function of exact AE, AF, AWB,γ correction etc, many numerical value calculation, optimizing, balance need be performed as well. Digital signal processing device is a special CPU processing vast digital information. Digital signal processing technology is the core technology for digital camera manufacturers. The patent application in this area will be more and more. The latitude of exposure and depth of focus on digital camera are less than traditional silver camera so that the requirement of digital camera is high for the accuracy of exposure of shutter and focusing accuracy of lens, the exposure controlling and focusing controlling are task which are studied by every company, they will apply patent for itself.

No matter what kind of camera it is, silver or digital camera, the quality of image has been continuouslyimproved and more functions have been introduced. With the improvement of processing speed of digital signal, the delay between shutter and imaging will be shortened. There will be various product combining digital camera and other device.


9. Analysis and Forecast on Patent Applications in the Field of Coal Water Mixture (CWM)

CWM is a new kind of slurry fuel appeared in the earlier 1980th, it is called CWM (Coal Water Mixture) or CWF (Coal Water Fuel) and contains about 70% coal, 1% chemical additives, and the balanced water. The heat consumption of water thereof takes only 4% of the total heat value of CWM. The technique of CWM makes it possible for coal to be converted from a traditional solid fuel to a slurry fuel, and therefore brings about lots of advantages. These advantages include that CWM is easy to transport, high in combustion efficiency, easy to adjust in capacity, low in energy consumption and pollution, the technique also has a remarkable efficiency in economic consideration. The CWM study is highly regarded and supported in China, and has now reached the level of the top rank in the world.

Up to Dec. 2004, among the published Chinese patent documents, the patent applications in the field of CWM has reached 136, relating to the slurry making processes, devices, combustion, transportation and the use of CWM. Chart 1 and 2 reveal respectively the data of CWM patent applications each year and the distribution of the IPC of these applications. They shows that the amount of CWM patent application has experienced three obvious up-and-down since 1985. It is mainly due to the price wave in international and domestic energy source markets. The CWM technique has become more and more active, the amount of patent application kept increasing at the rate around 25% per year. Up to Dec. 2003, the published applications in 2003 had reached 22 pieces, the total number in the year is expecting about 36. These applications are concentrated mainly in the use of CWM slurry preparation(IPC:C10L), combustion(F23D, F23C, F23K, F24H), physical mixing and grinding(B05B, B01D, B01F), CWM vaporization and sewage treatment (C02F, C01J).

In the CWM patent applications, domestic applicants take the majority of 89%, while foreign applicants 11%, mainly from Japan and America. Chinese applicants are mainly China University of Mining & Technology, HuaMei CWS Unite Center, Zhejiang University, East China University of Science and Technology, CAS. The foreign applicants are mainly COM company in Japan and DOW CHEM CO. in America.

According to the technical contents of these patents, Chinese applicants have reached the international leading level in the preparation processes of cleaned coal floatation and washing. But when taking the CWM technique as a whole, national applicants have not yet built up an efficient patent pool, the problems of separated distribution in applicant, of lacking series applications and the narrowness in the technical coverage still remain. Meanwhile, the study of CWM additives has been the key factor in hindering the development of our CWM technology, but this subject has rarely been concerned in the domestic applications. Compared with Japan, of which the amount of the CWM application has reached 1,022, the amount of our CWM applications is relatively low.

Today, as the quickening of the CWM industrialization in China, we have completed CWM preparation plants in ZaoZhuang, XingTai, BaiYang river, DaTong, ShengLi mining, ZhuZhou, etc. For these reasons, we must give a great consideration in making use of patent stratagem to provide an efficient technical support and well survived environment for the advanced development of CWM industry in China.
