PHILADELPHIA and LONDON, November 6 /PRNewswire/ --

- Japan Leads Patent Output as Chinese Inventions Grew By 300% in 2000-2005.

Thomson Scientific, part of The Thomson Corporation (NYSE: TOC; TSX: TOC) and leading provider of information solutions to the worldwide research and business communities, today revealed new research comparing patenting numbers in Japan to those in Brazil, India, Russia and China, some of the world's most important emerging economic markets. Using Derwent World Patents Index (DWPI), Thomson Scientific's comprehensive database of global patent documents, expe analyzed the number of patent applications between 2000 and 2005.

Patenting trends show that the number of Chinese inventions has increased 300 percent over the last five years. China is second only to the United States in patent authorities of natural products and polymers which include pharmaceuticals and medical or chemical testing. However, in 2005 Japan produced four and a half times more patents than China, remaining a driving force in Asia in terms of creativity and innovation.

"Patent analysis provides a valuable accurate snapshot of levels of innovation and economic activity in a particular region or country," said Mark Garlinghouse, vice president, Thomson Scientific, Asia Pacific. "If China's growth continues at this rate it could soon rival Japan as Asia's innovation engine."

Other highlights of the research include: -- Slight decline of Japanese patent filings over the last five years; down from 365,000 in 2000 to 335,000 in 2005. -- Six of top seven areas of interest for India are in chemical, pharmaceutical and/or medical innovations. -- Chinese patents have risen steadily from 25,000 in 2000 to 72,000 in 2005. -- Brazil is focusing its research in the fields of domestic and industrial electrical equipment and is 13th and 17th highest in the world respectively in terms of volumes.
