  Kay, L. ; Newman, N. ; Youtie, J. ; Porter, A.L. ; Rafols, I.: Patent overlay mapping : visualizing technological distance.

  Abstract: This paper presents a new global patent map that represents all technological categories and a method to locate patent data of individual organizations and technological fields on the global map. This overlay map technique may support competitive intelligence and policy decision making. The global patent map is based on similarities in citing-to-cited relationships between categories of the International Patent Classification (IPC) of European Patent Office (EPO) patents from 2000 to 2006. This patent data set, extracted from the PATSTAT database, includes 760,000 patent records in 466 IPC-based categories. We compare the global patent maps derived from this categorization to related efforts of other global patent maps. The paper overlays the nanotechnology-related patenting activities of two companies and two different nanotechnology subfields on the global patent map. The exercise shows the potential of patent overlay maps to visualize technological areas and potentially support decision making. Furthermore, this study shows that IPC categories that are similar to one another based on citing-to-cited patterns (and thus close in the global patent map) are not necessarily in the same hierarchical IPC branch, thereby revealing new relationships between technologies that are classified as pertaining to different (and sometimes distant) subject areas in the IPC scheme.

  Abstract: In the United Kingdom, the BBC is principally known for television and until recently there was no difficulty in finding BBC content on your TV. There was only one channel and then two. It wasn't until the late 1950's in the UK that commercial TV provided an alternative, but even then we owned the transmitters, the distribution and crucially the BBC remained 1 and 2 on the dial. The explosion of multi-channel TV and now internet has meant falling market share inevitably and the arrival of digital television has meant hundred of channels, thousands in the case of the internet, and the need to invent new forms of navigation. Today, the BBC does not control those guides or the navigation systems that will inevitably drive people to the content of the future. Eastenders is a much loved BBC soap opera which gets about 8 million viewers a week, but some people no longer associate the programme with the BBC. Many people in the UK get their television via Rupert Murdoch's SKY platform and so the credit often goes to the aggregator. In Focus groups, we hear comments like »I watched Eastenders last night on SKY«. Today British consumers, who have only just got used to hundreds of television channels are now being bombarded by a second wave of content. There are podcasts, vodcasts, webcasts, user generated content - and on its way even more on demand video content as the world's major media companies open un 7 day output and their archives directly to consumers.
