    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?

    Both public and private researchers observed in each of the three disclosure regimes, though

    private researchers more likely to be associated with patents or PP Pairs overall, ~25% of

    the Human Genome is protected by formal IP rights (Murray and Jensen)

    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)

    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

    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

    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

    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

    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.

    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.
