  1. The Gold rush to Nano-technology ; Carbon Nanotube Jonghwankim Department of physics

  2. 1. Nanotechnology • What is nano? 10¯⁹ m – Quantum Effect • Big areas Pharmaceutical, dendrimers, canbon nanotube, fullerences, nanowires

  3. 2. Carbon Nanotube

  4. 2-1. Carbon Nanotube

  5. 3. Properties • Mechanical Property 200 times stronger than Iron, but much lighter • Electrical Property 1,000 times better than silver and copper • Thermal Property 20 times better than copper • Other Property

  6. 4. Application • Display Panel (electron emission) • High-condensed Semiconductor

  7. 5. Patents • Patents on how to produce Carbon Nanotube 1. NEC (Dr. Ijima, Japen) ; Chemical Method 2. CNI (Nobel Laureate, Richard Smalley, Rice University) ; Laser Method • Patents on applications 1. Samsung Electronics 2. Hitachi, LTD. 3. LG Electronics

  8. 5-2.Patents

  9. 6. Infringement • As of late March 2005, 3,818 U.S. nanotechnology patents had been issued with another 1,777 patent applications awaiting judgment. • Many problems occurred Lots of patents overlapped!

  10. 6-2. Infringement

  11. 6-3. Infringement • Examples of overlapped patents One covers silicon nanocrystals having average diameter between 1 and 30nm. Another covers any nanocrystal emitting light in a spectral range no greater than than 60nm. (from Law Firm, Foley Lardner) • Reasons competitiveness ( Gold Rush ) Lack of uniform handling in US PTO (140 examiners for 257 patent on nanotubes)

  12. 6-4. Infringement • Want to start NEW business, BUT!! • Cross licenses should be considered

  13. Thank you • Reference 1. Carbon Nanotubes - Who Owns the Patents and IP Rights for Carbon Nanotubes?, ETC Group 2. Nanotechnology Patent Explosion, Stephen B. Maebius, Foley Lardner 3. Carbon Nanotubes - Who Owns the Patents and IP Rights for Carbon Nanotubes?, Peter Herbert, Lux Research, Inc. 4. Many other sources from the Internet
