Outline of Core Lectures
• The point is to embody in products as much as possible asset-specific human capital of the firms
• IPRs typically help, but…
• There are other appropriability stragies than IPRs • secrecy, lead-time, marketing, complementary
services and sales
• Holistic approach to IPRs
• Use many IP and complementary tools

Brief Overview of IPRs
Consider waiving IPRs
- Monitoring is not possible
- Not enough resources for monitoring and defending IPRs
- IPs would imply too much disclosure
- IP protection would be easy to “invent around”
- Invention becomes obsolete rapidly
- Other appropriability mechanism cheaper and more efficient

Two puzzling facts
1. Firms rely more on patent protection
E.g. Microsoft, Sun, HP, Nokia
E.g., Microsoft’s strategy change
• In 1976 software was not patentable and Microsoft relied on copyrights and trade secrets.
• Due to a reinterpretation of the US patent law (the S upreme Court decision (Diamond v. Diehr, 1981), software patenting became possible.
• Microsoft did not bothered to patent its software professionally, partly because of ideological reasons (Gates thought such patents are bad for industry and society)
• In the early 2000 Microsoft’s non-patent IP strategy became unsustainable:
- It was sued all the time and had to pay hundreds of millions dollars
- Antitrust authorities wanted Microsoft to disclose its trade secrets
- Open source software started to bite in its operating system market power
• Microsoft had basically three choices:
1) Patent and use patents defensively/strategically
2) Patent and use patents offensively (sue others)
3) Patent and use patents commercially (license)
• Microsoft’s choice: in 2003 they hired IBM’s former IPR boss and established IP licensing division and a new business unit
• Their purpose is to ensure that Microsoft’s technologies are patented and that it gets revenue out of the patents
• This is a fundamental change as not all IT firms regard their IP unit as a business unit

Fact 2:
• In surveys, firms claim that other appropriability mechanism are superior (Cohen et al. 2000, Arundel, 2001, Byma and Leiponen, 2006)
• Anecdotal evidence: firms keep in secret what ever they can
• The puzzle: why do firms patent while claiming that patents are no good in protecting their inventions?
• An answer: arms race
• you need to acquire IPs because everybode else is doing so
• a patent thicket/minefield where you will certainly infringe the rivals’ patents and face law suits
• however, if you have a large patent portfolio, your rivals will most likely infringe your patents’ too settle the case via cross-licensing
• It can even be so that the firms were better off without IPs (and that shows up in the surveys)
Using game theory: The arms’ race as a prisoners’ dilemma game
• Cf. the consumer protection game in my previous lecture
• Consider two firms/players, 1 and 2, that have two strategies, Secrecy (S) and Patenting (P).
• a strategy: a complete contingent action plan fro a player in the game
• Let 1(i,j) be the payoff of firm 1 when it uses strategy i and firm 2 uses strategy j, i,j{S,P}
• Let 2(i,j) be the payoff of firm 2 when it uses strategy j and firm 1 uses strategy i, i,j{S,P}
• A pair of strategies is a Nash equilibrium
• if firm 1’s choice is optimal given firm 2’s choice
• and
• if firm 2’s choice is optimal given firm 1’s choice
• E.g., Secrecy (S,S) is a Nash equilibrium if 1(S,S) 1(P,S) and 2(S,S) 2(S,P)
• A dominant strategy is such that there is one optimal strategy for a firm no matter what the other firm is doing
• E.g., Secrecy (S,S) is a dominant strategy equilibrium if 1(S,j) 1(P,j) for i,j{S,P} and 2(i,S) 2(i,P) for i,{S,P}
• A dominant strategy equilibrium is a Nash equilibrium but it is much stronger equilibrium concept so we except it to be the equilibrium outcome of a game
• In a prisoners’ dilemma type game the dominant strategy equilibrium is not Pareto efficient, i.e., the firms were better off if they could commit to employ another pair of strategies.
• It may be that patenting (P,P) is such dominant strategy equilibrium!
• let profit of a player and c the cost of patenting

The Arm’s Race:Payoff Matrix
• If >c, then secrecy would offer higher payoffs but a firm is forced to patent since the other firm is doing so

Consumers’ problem
Note 1) The patenting game arises because
- firms can and do make independently similar innovations
- the independent invention is not a defense against infringement in the patent system
- more relevant to the first-to-file system than first-to-invent
- however, the first-to-file is counterbalanced with prior-user-rights
Note 2) If patenting is indeed a Pareto inefficient dominant strategy Nash eq., it will justify disclosure/contract theory of patents
• even if patent system is weak and implies much disclosure, the firms will patent
• what happens to the incentives to innovate?
Note 3) The surge of patents may be caused by a shift in competitive advantage of the patent holder as against the firms’ resorting to secrecy but not in the appropriability capacity of secrecy
• E.g. the US legal changes since the early 1980s
• With a weaker competitive advantage of the patent holder there may be two Nash equilibria, Secrecy and Patenting
• If secrecy yields higher payoff to the firms, we may speculate that most firms are able to coordinate to that equilibrium over time

Note 4) The big question: Are R&D and patents/IP complementary competitive strategies or substitute?
• If substitute, an increase in patenting will mean less R&D
• If complementary, the patent system works as it should
• Max profit without R&D, 2 with R&D.
• Cost of investment R<
• If both firms in the market, each of them gets a share s1/2 of the max profit.
• s is a measure of competition s→0 = a lot of competition (Bertrand) s→1/2 = collusion
• If one firm in the market, it gets the whole market
• the patent holder can exclude the other from the market
• If both apply for a patent, Pr. of getting it 1/2

“Innovation and IP in Financial Services Sector ”Tuomas Takalo, 21.2.
www.takalo.net
Tufano, Handbook of Corporate Finance, 2003, Frankel and White JEL-2004
• Financial service sector
• financial intermediaries (e.g., banks, mutual funds, venture capitalists),
• investment service providers
• stock market infrastructure (e.g., exchanges and clearing & settlement),
• payment media (e.g., credit card companies, interbank paymets)
Part IV. Innovation and IP in Financial Service Sector
• Innovation in financial services
• Product innovations. E.g., new derivatives, new mutual funds, new payment media
• Process innovations. E.g., new process for interbank payments, new methods for calculating the value of mutual funds
• Cumulative
• E.g., equally weighted market fund 1971, value-weighted fund 1973….exchange traded funds 1990…holding company depository receipts 1998
• Rapid innovation rapid diffusion

Innovation in other sectors
Innovation in financial service sector
Welfare effects of financial innovation
Note: financial innovation can be harmful
- Any innovation can be harmful due to the (theoretical) possibility of overinvestment/duplication
- But there is an extra reason to worry in case of financial services sector: It is heavily regulated
• Transactions costs• Stability
a lot innovation to circumvent regulation
a concern for the stability
• Appropriating strategies in financial services traditionally:
• Patents were not available (in such a way as today)
• Secrecy does not work for product innovations
• Copyrights?
• do not prevent imitation
Imitation of product innovations rapid
Lead time & marketing the best means of appropriation
– Other mechanisms:• Reputation & Size• Complementary assets• Joint ventures• Regulatory barriers to entry
• However, the things have changed in the U.S & Asia
• Patents are not new to financial services• But today’s patents are rather different
• Europe?
