The Social Accumulation of Knowledge The mere production of knowledge does not guarantee that others
will be able to exploit that knowledge (Polanyi; Mokyr)
Tacit Knowledge Trade Secrecy
Intriguingly, the ability to provide private incentives to produceknowledge that can be exploited by others is a the heart of
modern theories of endogenous growth (Romer)
Open Science and Patenting are two institutional arrangementsthat require the disclosure of knowledge (Dasgupta and David)
By and large, the spheres of knowledge governed by Open Scienceand Patenting are assumed to be relatively independent

Human Genome Project The Human Genome draft was published in early 2001,
providing almost-comprehensive location and sequence
information for more than 20,000 individual genes
Without a doubt, this is the most important, most wondrous mapever produced by humankind. (Bill Clinton, 2000) Two principal routes for documenting further explorations of
individual genes
Scientific publications -- kudos & naming rights
Patent disclosures protection of discoveries and licensing rights What do we know today about the Human Genome? How has
that information been disclosed?

The BLNK gene We describe here the identification of a novel B cell linker protein,
termed BLNK, that interfaces the B cell receptor-associated Syk tyrosine
kinase with PLCgamma, the Vav guanine nucleotide exchange factor, and
the Grb2 and Nck adapter proteins (Fu et al,Immunity, 1999).
the discovery of molecules which interact with either Grb2 or PLC- play a role in the regulation of signaling pathways are desired.
Accordingly, it is an object of the present invention to provide such
molecules, termed BLNK proteins, and to provide methods of using such
molecules in screening assays. (USPTO patent 5994522)
While the patent and paper disclose essentially the same information inthis congruentpatent-paper pair, other publications go beyond the patent
disclosure to offer a landscape for future research orenable imitation
above and beyond the patent disclosure

Research Questions What are the key factors shaping the disclosure of
knowledge in the form of scientific research publications,
patents, or both?
A Theory of Patent-Paper Pairs How does disclosure strategy depend on the disclosure
environment?
Patentability Requirements? Public versus Private Funding? The Potential for Licensing in the Market for Ideas? The Impact of Scientific and Market Competition?

Scientific Researchers and
Private Research Investors Regardless of potential commercial returns, scientific researchers realize
benefits from knowledge disclosure through scientific publications Intrinsic preferences for kudos Signaling to both private and public employers
Regardless of potential impact on the scientific community, privateresearch investors realize benefits through the protection of ideas
Formal intellectual property rights (patents) Trade secrecy and inimitability
Researcher preferences for scientific disclosure may conflict with thecommercial objectives of research funders May be willing to trade of wages for ability to publish in the scientific
literature
Disclosure strategy results from the contract between researchers andresearch funders when bargaining over compensation

The Model Single researcher is hired by a single firm in order to produce
knowledge that potentially has significant scientific value and/or
commercial returns
The firms expected return from the innovation depends on theirability to limit potential competition Relative to secrecy, a patent grant increases the fixed cost of entry () but
only a imperfect chance of blocking entry () However, disclosures through patenting (dPAT) or publication (d) reduce the
fixed cost of entry
The researcher cares about their monetary compensation (w) andtheir ability to earn kudos through publication (bs)

Disclosures Jointly Impact on Entry Consider a potential entrant who faces the following profit
function
andare the strength of patent protection is the degree of fidelity between disclosure paths bEis the reduced marginal cost of entry due to
disclosures dand dPAT
is distributed uniformly on [0,1] + bE< 1 (entry always uncertain)
The potential for entry is increasing in both patenting and publicationdisclosure, while the cost of entry is increasing in the receipt of a patent

Complete Overlap Suppose that the knowledge disclosed in a patent and
publication were exactly the same.
Then if decide to patent, there is no additional cost inpublishing and vice versa.
Would only observe secrecy and patent-paper pairs.

Two key expressions shape the decision of whether to allow
scientific disclosure, patenting, or produce patent-paper pairs
Consider the choices that maximise surplus Scientific disclosure? consider the ratio of the marginal
benefit versus marginal cost of scientific disclosures.Choose no disclosure if
Patent? consider the ratio of the marginal benefit to themarginal cost of publicationchoose to patent if

Complementarity: when patents and publications are partially
overlapping in terms of disclosure, the patent-paper regime expands
when the strength of intellectual property protection increases

Sources of Complementarity Fidelity (): as a grows, this increases patent-paper pairs
relative to other regimes.
Intuition: the marginal cost of disclosure is lower if there is apatent as less entry-facilitating knowledge is likely to begenerated.
Patent effectiveness (): as the effectiveness of a patent inblocking entry rises, this increases patent-paper pairs
relative to other regimes.
Intuition: if a patent can actually block entry (= 1), thedisclosures are not commercially harmful.

Possibility of Zero Wages If publishing maximises joint surplus, w = 0
Increase duntil wage is constrained Beyond this point, dused as compensation.
Increasing More likely to take out a patent If there is publication, negotiate more disclosure
Increasing dPAT Less likely to take out a patent If there is a publication, reduces disclosure
Stronger IP protection (higherand lower dPAT) stimulatesopenness in science

Dynamics Suppose that scientists and firms live two periods
Overlap with other generations Future kudos generated by citation
Past knowledge reduces future capital costs, k Full transfer (under contracting): zero future costs Partial transfer (through publication): (1-dt-1)k
Firm owns patent and can license it to next generation Disclosure, fee & wages now a 3-way negotiation Use Nash bargaining solution Past publication gives future pair an easier work-around if there is
no license work-around possible (on same research path) with
probability.

If no patent, = 0 If patent but no publication, = k/3 If patent but publication, = k(1-(1-)dt-1)/3
Patent-Paper Pairs Forsufficiently high, patent-paper pairs can be an
equilibrium

Other implications Look only at symmetric dynamic equilibria Inter-temporal complementarity
Only worthwhile publishing if expect future scientific work tobe published (so can earn a citation)
Therefore, always exists a commercial science or secrecyequilibrium.
Domain of open science is expanded as a result ofsubstitutability
Key issue: who should own IP rights?

Conclusions The disclosure strategy of privately funded research is grounded in the
disclosure environment and is shaped by the bargaining over disclosure
between scientific researchers and their funders
Rather than an anomaly, patent-paper pairs emerge as an equilibriumoutcome in which scientific researchers trade off wages in order to gainscientific credit, while investors (private or public) seek to retain the
ability to capture value from these dual-purpose discoveries
Interestingly, in most circumstances, increases in the strength of formalintellectual property protection enhances the scope for patent-paper
pairs.
More generally, the model suggests that the key requirements forcumulative disclosure in the aggregate requires a careful evaluation of
the strategic foundations of disclosure strategy.
