WIPO Report Shows Internationalization of Patent Trends

Press Releases PR/2006/463 Rev.

A report released by the World Intellectual Property Organization (WIPO) on Monday, October 16, 2006, shows that the patent system is an integral part of increasing global economic activity, with the increase in patent filings closely mirroring economic growth around the world. The WIPO Patent Report 2006 shows that companies are increasingly using the intellectual property (IP) system to protect their investments in new markets. The report reveals that a total of 5.4 million patents were in force worldwide in 2004, the last year for which complete statistics are available.

"This comprehensive report presents a complete picture of worldwide patent activity in an easily-accessible format. It shows the distribution of patent activity around the world and contains detailed information on some of the important trends of the patent system," said Dr. Kamil Idris, Director General of WIPO. "Over the past few years WIPO has improved its collection and analysis of industrial property statistics to assist policy makers, practitioners and other interested parties in better understanding the impact of the patent system on economic and inventive activity around the world," he added.

The Director General said "The report shows a marked increase in the use of the patent system internationally. It also shows that the patent system is being used for its intended purposes, namely to stimulate innovation and promote economic activity." Dr. Idris further noted that the report shows an increase in the use of WIPO's Patent Cooperation Treaty (PCT). The PCT, which provides a simplified system for international patent filing, has become a major tool for companies seeking broad-based patent protection. The number of PCT applications grew at an average annual rate of 16.8% between 1990 and 2005 and topped 134,000 international applications in 2005. The PCT is now used in 47% of all international patent filings.

The number of patent applications filed worldwide almost doubled between 1985 to 2004, rising from 884,400 to 1,599,000 with an average annual rate of increase of 4.75% since 1995. This is in line with the average annual growth in world gross domestic product (GDP) of some 5.6%.

Since 1995 there has been a continuous increase in the number of filings by patent applicants in their country of residence, reflecting steady growth in domestic inventive activity. The bulk of the increase in total filings is accounted for by international patent applications. Large increases in foreign patents filings in countries like Brazil, China, India, Korea, and Mexico reflect the internationalization of markets and production. Companies seeking new export markets or investing overseas are keen on protecting their inventions in these key emerging economies.

The report notes a boom in patent filings in northeast Asia over the past 20 years, most notably with the emergence of China and the Republic of Korea as major industrial economies. For several decades Japan has been the largest patent office in the world with more than 400,000 patent applications filed by residents and non-residents in 2004. In only 20 years, China has become the 4th largest patent office in the world (by number of patent applications filed) and patent filings by Chinese residents grew more than five-fold between 1995 and 2004 to reach 65,786. Today, the Republic of Korea is the 3rd largest patent office in the world and is also experiencing very high growth rates with a three-fold increase in patent filings by residents between 1994 and 2004.

Although an increasing number of applicants are seeking protection for their inventions outside their country of residence, and emerging and fast-developing economies have been using the patent system more extensively, its use is still very concentrated. Five patent offices account for 75% of all patents filed and 74% of patents granted worldwide. These are the United States of America (USA), Japan, Republic of Korea, China and the European Patent Office (EPO).

The ownership of patent rights in force, or the patents granted over the past 20 years, shows even greater concentration, with residents of Japan and USA owning 29% and 22% respectively of all patents in force in 2004. As not every patent application translates into a patent - this may be for a variety of reasons, for example, an applicant may decide not to pursue the application or an application may be rejected - the number of patents that were actually granted in 2004 is 600,000, representing an average annual growth of 4% between 1995 and 2004.

A patent is granted for a period of twenty years, although extensions are possible in some circumstances. In 2004, of the total of 5.4 million patents in force worldwide, 81% were granted in six countries: USA, Japan, the United Kingdom, Germany, Republic of Korea and France. An analysis of the country of residence of the patent applicant, however, puts Japan at the head of the field followed by the USA, Republic of Korea, Germany, France and Russian Federation. It is to be noted that information on patents in force is not available for several offices that have relatively high numbers of patent applications, notably Argentina, Brazil, China, India and some European offices. Of the patents in force in 2004, 53% were filed in 1997 or later. Only 22% of the patents in force in 2004 were filed before 1994.

The report introduces the concept of patent intensity indicators that weight the number of patents by different measures of country size (population, GDP, research and development expenditure). Indicators of patent intensity show that Japan and the Republic of Korea, in particular, have very high rates of patenting as a proportion of GDP or of research and development activity. Per dollar of GDP, Japan and the Republic of Korea file five times as many patents as the industrialized countries of Europe and North America.

These indicators also show that many small industrialized countries have above average rates of patent filing, such as Australia, New Zealand, Finland, and Denmark. East European countries such as the Russian Federation, Ukraine and Belarus also have high rates of patent activity when compared with total GDP and with research and development expenditure.
