Yeah, so "greater" China is being used which was already well developed by outsiders to claim "China is the patent superpower" etc. I don't know about patents but China definitely is a copy-cat superpower ...
China works hard to develop its own technology. Here are some examples.

Rotor for 1,000MW Ultra-supercritical Steam Turbine
November 9, 2011
China has already manufactured a 12% Chromium high-quality forged rotor for an 1,000MW USC (ultra-supercritical) steam turbine under high pressure.
China’s strategy to meet its greenhouse gas commitment is to continue full steam ahead by converting its coal-fired power plant fleet from a conventional one to an ultra-supercritical one — a move that will decrease its energy intensity from coal-generated power by more than 20 percent.
A coal-fired power plant operates by boiling water to create a high-pressure steam that drives a turbine which produces electricity by moving an electrical wire through a magnetic field.
A conventional (or subcritical) plant typically operates at temperatures up to 1,050 degrees Fahrenheit and has an efficiency of between 33 and 39 percent. Operating a plant at higher temperatures and pressures can increase its efficiency, potentially lowering emissions of carbon dioxide (CO2) in the process.
A so-called supercritical plant operates at sufficiently high pressures and temperatures (between 1,000 and 1,075 degrees Fahrenheit) such that the water and steam become indistinguishable (the critical point of a liquid), allowing efficiency rates to reach 42 percent. An ultra-supercritical plant operates at temperatures of 1,075 degrees Fahrenheit and above and can achieve efficiencies of more than 42 percent.
China has jumped into the ultra-supercritical game with both feet. It is busy building supercritical and ultra-supercritical power plants at an astonishing rate — a whole lot faster, by the way, than we are here in the United States. And China’s ultra-supercritical power plant that went online in Yuhuan in 2006 reportedly holds the record as “the world’s cleanest, most efficient and most advanced ultra-supercritical units” with an efficiency of 46 percent.
Until now, the key high temperature equipment for supercritical and ultra-supercritical power units were mainly imported from foreign countries. China currently requires our national enterprises to domestically manufacture the key high temperature equipment. For making seamless tubes and large pipes, Chinese enterprises will be equipped with more 35MN, 60MN and one 350MN extrusion machines in the near future.
Large-scale castings for 1,000MW USC steam turbine already can be made in China. Large-scale forging have been also trial-produced. High-purity low alloy steel forging for low pressure rotor and 12% Cr high-quality forged rotor for 1,000MW USC steam turbine high pressure rotor are made in China."

Shanghai Synchrotron Radiation Facility (SSRF), a third-generation of synchrotron radiation light source passes national inspection on January 19 and will be open to home and abroad scientific research, according to Shanghai Institute of Applied Physics, Chinese Academy of Sciences (SINAP).
SSRF is the biggest scientific platform for science research in China up to now. The construction of the project started on Dec 25th, 2004 in Shanghai, and cost 1,200 million yuan (about 176 million U.S. dollars).
The facility consists of three accelerators: a 150Mev electron LINAC, a 180-meter booster that can increase the electron energy from 150MeV to 3.5GeV in 0.5 second, and a 3.5GeV electron storage ring with a perimeter of 432 meters.
The project also includes 7 initial beamlines and experimental stations.
The mega experimental platform will then help carry out research on life sciences, medicine and pharmacy, new material, physics, chemistry, petrochemical industry and biotechnology.
[Many] hundreds of scientists and engineers from universities, institutes and industries in domestic and even overseas will be able to use the facility to [perform] research and experiments.

What is a Synchrotron Light Source?
A synchrotron light source is a very large machine designed to produce intense beams of light. Millions of times brighter than an X-ray, synchrotron light is generated by using powerful magnets to accelerate electrons that are traveling near the speed of light.
Infrared, ultraviolet and X-ray light is shone down beamlines to end stations (small laboratories) where scientists can select different parts of the spectrum to view the microscopic nature of matter, and investigate it at the scale of atoms and molecules. Synchrotron light is an indispensable tool in many research areas including physics, chemistry, materials science and crystallography, and is increasingly being used in medicine, geological and environmental studies, structural genomics and archaeology. Many everyday commodities, from chocolate to cosmetics, drugs, surgical tools, computers and mobile phones, have been developed or improved using synchrotron light."

China and Taiwan have caught up with U.S. advanced five-axis machine tools
Advanced high-precision five-axis machine tool fabricating an engine block
"Foreign companies in China and Taiwan have caught up with U.S. technical capabilities, rendering stringent U.S. export controls moot." (see first paragraph in news article)
Let's do the math. From the seventh paragraph, 45 foreign companies produce advanced five-axis machine tools in the BRIC+Taiwan countries. "China has 20 indigenous five-axis machine tool companies; Taiwan has 22." 45 - 20 (in China) - 22 (in Taiwan) = 3 left in Brazil, Russia, and India combined.
For comparison, "there are six American companies dedicated to producing five-axis machine tools." (see fourth paragraph in news article)

U.S. Precision Machine Tool Industry Is No Longer A Global Competitive Force
March 5, 2010 Volume 17, No. 4
By Richard A. McCormack

U.S. producers of some of the most technologically advanced machine tools are in trouble, according to an assessment by the Department of Commerce.
Sales of high-precision five-axis machine tools are declining. U.S. share of global exports is in a free fall. Foreign companies in China and Taiwan have caught up with U.S. technical capabilities, rendering stringent U.S. export controls moot. U.S. companies are being purchased by foreign rivals. A lack of training programs has created a shortage of skilled workers able to use the complex machinery. Commercial and U.S. government customers prefer foreign machine tools. Export controls are hampering foreign sales.
The entire U.S. machine tool industry spends only $1 million a year on research on five-axis machine tools.
These are some of the findings from a "Critical Technology Assessment" conducted by the Commerce Department's Bureau of Industry and Security.
U.S. producers of five-axis machine tools had sales of $253 million in 2008, down 11 percent from 2005 sales of $284 million. That was before the U.S. machine tool industry suffered a meltdown in 2009, when domestic consumption tumbled by 60.4 percent, according to the Association of Manufacturing Technology.
Sales of five-axis machines to domestic customers from U.S. producers declined by 19 percent from 2005 to 2008, from $242 million in 2005 to only $195 million in 2008.
There are six American companies dedicated to producing five-axis machine tools, and at least 20 in China. Five-axis tools are used for the production of precision components in the aerospace industry, in making gas and diesel engines, automobile parts, and throughout the medical, textile, oil, glass, heavy industrial equipment and tool industries. "Many other industries are discovering the advantages of these machines," says the Bureau of Industry and Security (BIS).
Yet "only a handful of U.S. producers actually manufacture five-axis machine tools in high volume and most generate less than 10 percent of their annual net finished machine tools sales from five-axis machine tool business lines," according to the market and technology research report from BIS.
U.S. producers of five-axis machine tools exported only $58 million worth of equipment in 2008. In a tally of global exports of all machine tools, the United States -- with exports of $740 million -- accounted for only 4.3 percent of global exports in 2007.
...
BIS also assessed foreign producers of five-axis machines. It found that not one of the 45 companies that are indigenous to Brazil, China, India, Russia and Taiwan use U.S. technology, parts, components or materials. China has 20 indigenous five-axis machine tool companies; Taiwan has 22. None of these companies have to deal with the types of export restrictions facing American firms.
As a result, these companies are able to produce all the machine tools that are in demand in China and Taiwan, plus they are "able to produce in sufficient quantity to export to other LRCs," says BIS.
One of China's five-axis machine tool makers has 24 distinct models. China now has 28 companies capable of building more than 1,000 CNC machine tools. There are 130 Chinese companies with annual capacity of more than 100 machine tools. The country is now supplying most all of its own demand, with only 10 percent of the market being supplied through imports. "In 2005, approximately 59,600 units of CNC machine tools were produced in China," according to the BIS report.
In 2007, the combined amount of CNC metal-cutting and forming tools produced in China was 126,268, more than double the amount produced in 2005. China is now supplying its own demand for five-axis machine tools used throughout its military.
The BIS quotes the Export Compliance Working Group of the American Chamber of Commerce in the People's Republic of China as saying: "Given the existing domestic and joint venture development and the foreign availability of high-level machine tools, U.S. companies could not make a material contribution to China's military development. China's military demands are already satisfied by domestic and foreign supply."
The United States exported 515 five-axis machine tools between 2005-2007, and only 12 of these went to China. DMTG, China's largest producer of machine tools, exports products to more than 100 countries.

BYD to sell F3DM-model electric cars in Shanghai
Jul. 30, 2010 (China Knowledge) -
China's largest rechargeable battery maker and a well-known automobile producer, is set to sell the F3DM hybrid vehicle to customers in Shanghai by the end of the month, the Shanghai Daily reported.
The F3DM, the world's first mass produced plug-in hybrid car model, is able to have a 60-kilometers drive on a single charge. The battery can be fully charged in seven hours at a household outlet, and semi-charged in 10 minutes at a professional one.
BYD may also raise the output target of F3DM this year in anticipation that the government's stimulus plan will boost sales, said an official within the company.
The Chinese government plans to invest RMB10 billion, to speed up the commercialization of new energy vehicles. It aims to have 500,000 green cars on the roads by 2012. Subsidies up to RMB60,000 will be granted for purchasing a new energy vehicle.
MidAmerican Energy Holdings Co, a subsidiary of Berkshire Hathaway Inc that is controlled by Warren Buffett, holds a 10% stake in BYD."
