**Issued percentage of patents shrank - suggest decline in quality
**Share of licenses yeilding positive royalties shrank dramatically
**Though any patent with a marginal positive benefit greater than its cost of issue (assuming research costs are sunk) should be applied for.
*Patents from UC, Stanford and Columbia more frequently cited that non-academic - implying higher quality
*UC and Stanford's patents appear to have increased in importance post 1980 (as measured by citations)
