Biotechnology - Genomic and Proteomics/Overview of Economics of Intellectual Property in BGP

Where does the literature says IP works and does not work?

Where IP does work

• More effective in industries with high R&D costs
  • “On average, a lack of patent protection would have prevented the development of 60% of pharmaceutical and 38% of chemical inventions. In most sectors, a lack of patent protection would have had little impact, resulting in 17% fewer inventions in machinery, 12% less in fabricated metals, 11% less in electrical equipment, and no effect at all in office equipment, motor vehicles, rubber, and textiles.” (Arundel pp. 11)
• More effective in industries like Biotech, where (in the US) research methods can be patented
  • research tools develop faster in biotech than in other industries - so there's a profit to be had just coming up with new research processes (Harison pp. 26)
  • Current US IP law does not make a distinction between discovery and invention, could have possible impact on innovation (pp. 28)
• Patents do work for strategic purposes - in fact, strategic use of patents seems to be becoming more commons
  • “The patenting strategies of American firms appear to be strongly driven by the wish to block competitors and to prevent copying. The use of patents as a means of sharing information, for example through licensing or in negotiations, is less important for American firms than for European and Japanese firms.” (Arundel pp. 13)

Where IP doesn't work

• Less effective in industries where lead time provides big advantages
  • von Hippel and Levin both found that companies preferred to protect innovations through secrecy and lead times (pp. 3)
• In general patents less important than other methods of capitalizing on innovation (Arundel pp. 7-8. Graph on 8)
• Patents do not work well for spreading information
  • only a small number (3%) of high technology firms use patent and copyright publications sources of new information. Compare to trade conferences: 70% (pp. 3,5)
• Protecting product innovations (Levin pp. 794):

	Processes	Products
Patents to prevent duplication	3.52 (0.06)	4.33 (0.07)
Patents to secure royalty income	3.31 (0.06)	3.75 (0.07)
Secrecy	4.31 (0.07)	3.57 (0.06)
Lead time	5.11 (0.05)	5.41 (0.05)
Moving quickly down the learning curve	5.02 (0.05)	5.09 (0.05)
Sales or service efforts	4.55 (0.07)	5.59 (0.05)

is there data on "how much of an increase of the tendency towards enclosure".

sub-question: e.g. how much does the biotechnology field have patented? Has this movement increased over time?
