China’s Government Admits Chinese Patents Are Pretty Bad – Businessweek

For years, China’s leaders have exhorted the country’s businesses to become innovative. After all, a glorious country like China that is reasserting its role as a global superpower should be known for more than just its copycat and me-too companies. So while Chinese presidents come and go, the message is the same: Whether it’s Jiang Zemin, Hu Jintao, or the current boss, Xi Jinping, the country’s leaders have consistently talked about the importance of local innovation. Paraphrasing Xi’s remarks at a speech earlier this month at the Chinese Academy of Science and the Chinese Academy of Engineering, the Xinhua news agency reported that the government’s goal is to “push forward the fusion of science and [the] economy, so that science and technology strength can be transformed into industrial and economic power.”

By China’s own scorekeeping, though, the country’s innovators still have a way to go before they can meet the Communist Party’s expectations. While the number of patent applications inside China is “booming,” according to a report today by Xinhua, “the quality of patents is still poor.” Writing about a report to the Standing Committee of the National People’s Congress, China’s rubber-stamp legislature, Xinhua added, “China owns very few patents featuring originality and high or core technology.” Fewer than 1,000 Chinese patents have won recognition from counterparts in the U.S., Europe, or Japan, added Xinhua.

China is making progress. The gold standard in international patents remains the U.S., and Chinese from the People’s Republic applied for almost 6,600 patents in the U.S. last year, according to data from the U.S. Patent and Trademark Office (USPTO).  That’s just ahead of France and more than double the number from India. China had the sixth-largest number of patents granted by USPTO. Still, China’s innovators are hardly leaders in the U.S. The Chinese total of 6,597 U.S. patents puts it far behind Japan’s 54,170 applications. Even more embarrassing, Taiwan, the island that Beijing considers a province of China, had 12,118 patent applications granted.

Chinese scientists unveil energy-generating window | South China Morning Post

Scientists in China said on Thursday they had designed a “smart” window that can both save and generate energy, and may ultimately reduce heating and cooling costs for buildings.

While allowing us to feel close to the outside world, windows cause heat to escape from buildings in winter and let the sun’s unwanted rays enter in summer.

This has sparked a quest for “smart” windows that can adapt to weather conditions outside.

Today’s smart windows are limited to regulating light and heat from the sun, allowing a lot of potential energy to escape, study co-author Yanfeng Gao of the Chinese Academy of Sciences said.

“The main innovation of this work is that it developed a concept smart window device for simultaneous generation and saving of energy.”

Engineers have long battled to incorporate energy-generating solar cells into window panes without affecting their transparency.

Gao’s team discovered that a material called vanadium oxide (VO2) can be used as a transparent coating to regulate infrared radiation from the sun.

VO2 changes its properties based on temperature. Below a certain level it is insulating and lets through infrared light, while at another temperature it becomes reflective.

A window in which VO2 was used could regulate the amount of sun energy entering a building, but also scatter light to solar cells the team had placed around their glass panels, where it was used to generate energy with which to light a lamp, for example.

“This smart window combines energy-saving and generation in one device, and offers potential to intelligently regulate and utilise solar radiation in an efficient manner,” the study authors wrote in the journal Nature Scientific Reports.
