Summary
Two reports, related Description of new dataset
Exciting Comprehensive
Some beginning analysis Relationship (econometrically) between use of
intellectual property and various characteristics
Report 1: Comments, in general
Give me more confidence statistically T-stats and p-values, std. error, std. dev.
Probably all ok with your large numbers, but show them just the same
Give me more information about the variation in your data
Explore some of the “unstated” relationships and potential explanations for what you see, or don’t see, in the data
Tables 4-5: Survivorship, Distribution, Normalize
Tab 9 & 10: Who, and What

Yes, curved, but only marginally 1bn
Report 2: Amount of IP
One patent ≠ another patent, same with TM Weight / correct for
Cites? Claims? Words? Family size?
Table 3: What share exited, when? Age dynamics of time By Sector!!!
Table 7: Probit Regressions Give me some reduced form models testing specific
RQ’s or H1, H2, etc. prior to “full model” Control from size/quality of IP
Shameless plug
13,000 technology startups Software and allied, Biotechnology, Medical Devices, other sectors
In the field now, US Mit der ZEW, jetz in Feld.
In sum
Heroic effort, wonderful new data Hooray!
More statistics, more analysis Match up with survey data (extant, generate)
One Appendix on the CIS Self-generate survey data
Looking fwd. to what you do with it
