The focus area of this WIPO report (WIPO, 2011) is on inventions comprising a “component or a derivative of the H5N1 virus strain” for diagnosing, treating or preventing infections by H5N1 and H1N1 influenza virus strains in humans. The patenting trend observed in the ‘PIP-HN’ space differs from previous influenza-related patent searches (WIPO, 2006), differences are mainly due to the technology scope defined by the prior searches.
We observe a marked increase in the rate of global PIP-HN patent applications in the period 2004 to 2007. The marked increase could be linked to the outbreak of avian influenza (‘bird flu’) with pathogenic strain H5N1 since 2003. This strain of ‘bird flu’ reached Europe in 2005, and the Middle East as well as Africa in 2006 (Monke, 2006).
Trends in PIP-HN patent applications over all time. (Note: Patent applications may be unpublished for 18+ months. Therefore the number of reported patents for the last 2 years may be under-represented.)
