Animal Model of SARS Developed and Patent Filed
China's first animal model of SARS has been established in the Animal Research Institute under the Chinese Academy of Medical Sciences. The model uses rhesus monkeys to find SARS vaccines and medicines, as the animal's pathological changes to SARS are very similar to human beings.
Qin Chuan, vice director of the Animal Research Institute of the Chinese Academy of Medical Sciences and Peking Union Medical College, and his research team developed the animal model. They found the rhesus monkey is an ideal replacement for human beings in SARS research. They have also applied for a Chinese patent.
Under the help of the Chinese Center for Disease Control and Prevention, Qin and his team inoculated the SARS virus, isolated from SARS patients, to 15 rhesus monkeys through nasal cavities. Two or three days after the inoculation, all the monkeys had a fever that lasted for about four days; five days after the inoculation, the DNA of SARS virus was found in the experiment samples of some monkeys. Seven days passed when the DNA of the SARS virus was isolated from the four monkeys' experiment samples; 10 days passed, and the DNA was found in all of the samples. After 17 days passed, all the monkeys' SARS virus antibodies in their blood serum tested positive.
The experiments also found that the monkeys' lungs had pneumonia, dropsy, structural damage, bleeding and vascular hyaline degeneration separately in 5, 10, 15, 20 and 30 days after the virus inoculation. Meanwhile, keratin and immunity organization coloration found epithelia, macrophages and lymphocytes in infiltrative cells. After 30 days, the lungs of monkeys caught fibrosis. All the above show plenty of similarities to human beings in pathological changes once infected with the SARS virus.

Eternal Files in China for Anti-Cancer Biopharmaceutical Patent
Eternal Technologies announced recently that it has filed for a biopharmaceutical patent that represents a crucial technology in the company's goal of creating and marketing an anti-cancer medication.
The patent relates to the fusion of the genes for interlukin-2 and enterotoxin B and the preparation of the fused gene; the fused gene can be expressed in E. coli. International studies have shown that enterotoxin may protect against colon cancer. According to the National Academy of Sciences, which advises the U.S. federal government on scientific issues, a form of enterotoxin expressed in E. coli exerts an antiproliferative effect on human carcinoma cells while maintained in culture.
This patent application follows Eternal's previously announced filing of a patent in China for a related technology that expresses itself in the fusion of interlukin-2 with enterotoxin A, as opposed to enterotoxin B. Eternal is expecting to enter the China market with these products in the future.

First Patent Market Opens
China's first exchange for patent trading recently opened in an intellectual property service center in China's largest industrial city, Shanghai.
More than 370 patent projects and another 78 patents suitable for private enterprises were offered at the exchange, which offered opportunities for face-to-face talks between the patent holders and potential investors.
"For lack of convenient channels and places to release information, it was hard to make my patents widely known in the past, " said Wang Xiukang, who brought seven patent projects with him to the exchange from Yiwu City in eastern China's Zhejiang Province.
Statistics show that more than 42,889 patents have been approved in Shanghai since 1985, but only 10 percent have been productively utilized.
In the exchange, patent holders can easily advertise their patents at stalls, or by playing videos or distributing leaflets.
The monthly bazaar was jointly undertaken by the intellectual property service center and a small enterprises service center in the municipality. An on-line exchange for patents will also open in the near future.

China to Sidestep MPEG Patent Licensing Fee with Competing Chinese AVS Standard
According to a report from Dow Jones, multinationals like Microsoft, IBM and Philips have already signed up to be part of the new standard's working group.
The new format is aimed at rivaling technology from the globally dominant MPEG (Moving Picture Experts Group). MPEG-1 compression is used in the video CD (VCD) format common throughout Asia, while MPEG-2 is used on DVDs. MPEG-4 is widely used for compressing video for Web download and streaming and will also be the worldwide standard for streaming multimedia to third-generation (3G) phones.
Hardware manufacturers and content providers pay licensing fees to the MPEG Licensing Authority (MPEG LA) for the use of these compression standards. MPEG LA represents 18 patent holders, including Apple Computer and Sun Microsystems.
China, a key manufacturing hub, is also keen to avoid MPEG license fees. In future, companies selling AV equipment to Chinese consumers will have to pay licensing fees for the new format, which has been pegged at 1 RMB per device, or 12 US cents, much lower than current MPEG fees.
The competing Chinese standard, known as AVS, will be proposed as a national standard in 2004, according to Huang Tiejun, secretary-general of the Audio Video Coding Standard Workgroup, according to the Dow Jones report.
China is not the only Asian country that has developed a rift with MPEG LA. Japan's mobile video content providers have threatened to drop MPEG-4 compression technology--touted as crucial for delivering video to mobile handsets--unless license fees come down.
China is keen to move its IT infrastructure away from the dominance of Western companies and the fees levied by such firms. Like several other developing countries, it has put official support behind the open-source Linux operating system, and has created its own supercomputers.
