 We've just published the report on intellectual property activity in terms of filings worldwide for 2013 and what we see is a consistent trend once again of growth overall in the use of the intellectual property system which I think is one indicator of the knowledge economy. This is a consistent trend as I said over a number of years and we see it once again. So patent filings, for example, rose to more than 2.5 million patent applications throughout the world. I think the second thing that we see is that the IP filings tend to mirror the world economy and developments in the world economy. So we see a surge on the part of China still another consistent trend. We see strong growth in the United States of America in patent filings, patent applications. We see a negative growth rate although a small negative growth rate in Europe and a negative growth rate in Japan. So to some extent we see some mirroring there between this activity and the world economy. And then a third thing I would say is that of course once again we see tremendous activity in growth in China. So China now has the largest patent office in terms of numbers of filings, the largest trade at Mark Office in terms of number of filings, the largest design office in terms of number of filings in the world. Asia share is increasing driven mainly by China.
