In fact, the market punishes early innovators for teaching technologies to later innovators Can IP solve this problem? What is the problem with Strong protection to first innovator: everything infringes Weak protection to first innovator: nothing infringes Examples: laser, indigenous knowledge, light bulbs Basic and Applied Research Research Tools and Inventions Quality Ladders

Has high energy, is useful for lots of things, like reading and writing CD’s, eye surgery, carrying info in fiber-optics. Scientific Underpinning: Einstein 1916 paper. Pointed out that coherent photons would be emitted from an “excited” atom when bombarded with a single photon (amplification). First Implementation, the Maser (Charles Townes 1954). In the Microwave part of the spectrum (long wave lengths) Second Implementation, the Laser (Towns and Schawlow, idea published 1958, patent issued 1960).

New mediums for excited atoms (solid-state, gas, ruby, in the 1980’s semiconductors) 1960’s to 1980’s New uses surgery, printers, communications, spectroscopy Patent battles I: Townes’ maser patent assigned to Res. Corp. Townes’&Schawlow’s laser assigned to Bell Lab Research Corp sued Bell Lab (blocking patents) Patent battles II: Gordon Gould, laser contender, applied for laser patent 1957, awarded 1977, after a partial revocation of the Townes/Schawlow laser patent.

(Everyone here.) Who gets the profit? Townes made about $1m total. Gould patents eventually made about $17m per year. Better to be late, but not never. (BTW, CD’s) Einstein earned nothing. Did any of these inventors need “incentives?” Importance of reduction to practice: There was delay in filing; was a description enough? Working model?

Adapted by genetic methods to growing conditions in Texas (what about water!?) Challenges the export market of Pakistan. How should we think about this? Moral rights? Economic rights? Equity versus efficiency?

Biotech firm found a way to stabilize the oil, re- exports it to India. How should we think about this?

Not useful; filament burned too quickly. Remaining development: find the right filament, and keep it from burning (vacuum bulb). Eventual solution was carbon filaments, then tungsten 1860 Swan patent. Carbon filament in vacuum bulb. Still inefficient, but is the design still used. 1878 Edison, carbonised cotton thread. Lasted longer. Then carbonized bamboo, then tungsten 1907 Infringement fight betw Swan and Edison ended in a joint company 1883.
