3. ImprovementState of the art Quality q1 Quality Ladder Quality q2  =q2-q1 Quality

4. The case of improvements (quality ladder): decomposing forward protection Consider two innovators. e.g. a basic innovation with some commercial value and an application/improvement. The quality of the first innovation is q1 and the quality of the second is q2 Assume unit mass of consumers with a unit demand & Bertrand competition  if both products in the market, both the price and the profits on the second equal .  As to the basic innovation, both of them are zero  if the basic innovation is in the market alone, its price and profits are q1 Inventive Step/Novelty requirement = N, i.e., the application is patentable only if   N Leading breadth = L, i.e., the application does not infringe only if   L

5. Assume that the quality of the second innovation or the quality improvement  is stochastic (not known prior investing c 2 ) let the probability that  x be p(x) with p’>0.  the probability that second innovation is unpatentable = p(N) Patentable with probability 1- p(N)  the probability that the application infringes p(L) Non-infringing with probability 1-p(L) if N>L the second innovation can be unpatentable and non- infringing if L>N the second innovation can be patentable and infringing (blocking patents)

6. non-infringing unpatentable infringing unpatentable Case N>L Breadth Inventive step patentable, non-infringing

7. infringing patentable infringing unpatentable Case L>N Inventive step Breadth patentable, non-infringing

8. the effects of inventive step/novelty requirement: If the second innovation is unpatentable, it becomes freely available to everyone, including the first inventor  no incentive to invest if (1-p(N))  c 2 the effects of leading breadth: As we have seen, in case of infringement, it may pay to invest, depending of how the cake is divided between the first and the second innovator. If ex ante licensing is feasible, it pays to invest always if  c 2  optimal policy requires that L  N  ‘redundancy’ of the inventive step/novelty requirement  one cannot force profit sharing by using inventive step!  Why do we have novelty requirement/inventive step? - Make innovators more ambitious ?

9. Taking stock The basic problem of cumulative innovation is to make sure that there is incentive to make the first and later innovations There is a trade-off: if try to make sure that first innovation is made, this may but the later ones in jeopardy and vice versa. The nature of trade-off depends on the feasibility of ex ante licensing. If it is not feasible, the second innovators fears hold-up and has lower incentive to invest If it is feasible, the second innovation will be made but the problem is how to transfer enough surplus to the first innovator (the first innovator still fear hold-up)

10. Example of the second innovator hold-up problem: “Patent Trolls” 1) RIM-NTP case on BlackBerry patents A Canadian firm Research in Motion (RIM) established in 1984 by a couple of engineering students 1999 Launch of BlackBerry – a wireless email. Becomes hugely popular in the US About 4 million users today, e.g., George Bush Licensed its technology e.g. to Nokia 2000 an US firm NTP says that RIM’s BlackBerry violates its patent from 1991 and requires RIM to license  the firms go to the court RIM is a firm that only owns the patents of an individual inventor Thomas Campana, died 2004, and employs lawyers

11. 2002 a federal jury upheld infringement  NTP won 23.000.000USD of damages and an injunction Injunction, however, postponed pending appeal 2005 firms make an out of court settlement of USD 450.000.000 but that unravels soon afterwards (why?) Meanwhile, the court processes proceed and USPTO reexamines NTP patents. 23.2.2006. USPTO finds that at least one of the five key patents is invalid, serious doubts about the validity of the others 4.3. Firms settle: RIM pays 612.500.000 and NTP drops all cases.

12. What should we think about this? Sounds absurd but suppose NTP patents were valid. Then this is an instance of the later innovator hold-up NTP held the basic technology, RIM made the commercial application When the firms negotiated, the development effort of RIM were sunk and the RIMs technology was useless without permission to use it. Defending IPR system good for the incentives to create basic technologies and there might be a lot of future Thomas Campanas

13. However, it seems that NTP patents were not valid. Then this is very bad, we have indeed a troll that exploits the patent system without creating nothing.  there will be more trolls that wait that products become succesful and attack from “ambush”  potential innovators puts some probability of ex post hold up by trolls  society gets more DWL and less innovation Why did RIM settle? The courts put pressure to settle The uncertainty was biting the demand Its share price jumped up after the settlement Not settling and fighting would have been public good production, like an investment in innovation without IP protection

14. Case 2) Ebay vs. MercExchange Same kind of story with the following twist: In 2003 a lower court found that EBay infringed MercExhange patents, awarded damaged but not an injunction because MercExhange was not using the process itself ( a sort of patent troll?) MercExhange was not satisfied  the special IP appellation court CAFC reversed the decision  now in the Supreme Court Outcome can be fundamental to future US innovation Can trolls be market makers and nonetheless beneficial?

16. A key lesson so far: Ex ante licensing is generally good for the society as it never puts second innovation jeopardy It can be good also for the first innovator if the IP is overly strong - Suppose it costs K to invent around the patent of the first inventor - The imitator/the second innovator can choose whether to invent around or wait until patent expires - Suppose the payoff to imitation/second innovation  -The imitator’s problem: invent around if  –K  (1-T)   T  K/  -i.e., invent around if T is sufficiently high III. Management of Patents (other IPs) III.1. Licensing & Cumulative Innovation

18. In practice, however, ex ante licensing does not always occur E.g., otherwise we did not have patent trolls Why ex ante licensing can be infeasible? 1)Costs of monitoring rival patent portfolios: Firms should examine what has been patented prior investing in innovation This can be costly as patents are written in obscure manner - in particular if your goal is to be a troll you do not want that your patents are found prior investments There are many countries in the world – does going trough US and EPO patent databases suffice? Investment takes long time, even if you did not find any previous patent ex ante there may be some ex post Pending applications are kept secret

19.  continuous monitoring rival patent portfolios, while important, can be costly (trolls: you do not know who is your rival) Can weaken bargaining position ex post “Willful” infringement can increase damages 2) Benefits of non-monitoring: not all firm carefully monitor their own patent portfolios and do not notice infringements - the more successful your product, the less likely it will be that infringement goes unnoticed

20. 3) Difficulties in contracting in the process of negotiation, the second innovator may to disclose her idea to the patent holder – the patent holder can walk away with the idea, make the invention and patent it - For the same reason it may be difficult to find funding for innovation - Does not apply in the example of basic technology vs, commercial application the second innovator has private information about the costs or the value of her innovation - clear incentive to overstate costs and understate value - private info about the value can be mitigated e.g., by using royalty licensing but how to overcome the private information about the costs?

21. 4) Fragmentation problem “anticommons” the application may infringe several patents – it may be too costly to secure ex ante license from all of them - suppose three patent holders - It costs c to make the application, profits .  The ex ante cake  -c. - The inventor of the application negotiates with each of the patent holders separately - Assume equal bargaining power.  The inventor of the application should pay (  -c)/2 to each of the patent holders  impossible!  The patent holders should form a patent pool, collude or merge  antirust problems

23. Licensing of IP One can sell IP, like any other property, via negotiation, auction, and posted price/fixed fee. All IPs can and do get licensed, even trade secrets (e.g., Coca- cola) In theory, auction is usually the best way to sell an object. In practice, however, other ways are more popular. The same applies to IP. A popular method: output royalty with or without a fixed Licensee pays according to what he sells, e.g., % of final price per unit sold or x euros per unit sold A license can include a variety clauses. E.g., it can be exclusive: only to one or restricted number of licensees or non-exclusive: the licensor reserves the right to license the technology to any number of firms he wants exclusive license via auction in theory the best method Some licensing clauses/restrictions can cause antitrust problems E.g., exclusive dealing: requires that the licensee only resorts the licensor as sole supplier

24. Why selling an exclusive license via auction does not necessarily work? A thin market – i.e. not that many buyers Need to modify the technology according to licensee’s needs Auction and posted-prices can be equivalently efficient – posted prices easier to implement Auction not necessarily the best method if there is asymmetric information or moral hazard problems - usually there is: we talk about new technology Licensor can know the value of technology better and need to train the users Licensee can know the value of technology better Hold-ups dilute the efficiency of auctions – as we have seen (in licensing) hold-ups are pervasive

25. A consequence of hold-up problem: fundamental transformation in which a competitive situation changes to a bilateral negotiations almost always when you auction something, fundamental transformation looms! Fundamental transformation and cumulative innovation suppose that there are the first inventor with basic technology with zero commercial value, costs c B to develop two identifiable firms that can develop the application with cost c A the value of application  (T) where T is the (discounted) patent life one would expect that the first innovator auctions an exclusive license to the basic technology  competition drives the price of the license to  (T)-c A  the first inventor gets all the surplus without putting the application in jeopardy  the payoff of the first inventor:  (T)-c A - c B  policy-makers could set T=T* and all the problems would be solved

26. however, suppose that the application is patentable (but infringing), i.e., both firms can try to develop the application and the first to file/invent gets the patent to it, irrespective whether it has the license timing of events: 1) development of the basic technology 2) auction of the exclusive license 3) development of the application and competition for the application patent 4) commercialization solve backwards (SPE) stage 4: if the application patent and the license are held by the same firm, no problems if the application patent and the license are held by different firms, the two firms hold blocking patents. The licensee holds a right to the basic technology patent and the other the application patent  the firms need to negotiate over the cake  (T) (all costs are sunk at this stage). Let us assume 50-50 split

27. stage 3: the two firms invest in making the application and getting the patent, each firm wins with probability 1/2 the expected profits of the licensee:  (T)/2+  (T)/4-c A = 3  (T)/4-c A the expected profits of the non-licensed firm  (T)/4-c A  the non-licensed firm invest if  (T)/4  c A stage 2: the firms bid for the license Equilibrium bid is the difference between the profits of the winning bidder and the losing bidder, i.e., 3  (T)/4-c A - [  (T)/4-c A ]=  (T)/2 Bid  (T)/2   (T)-c A iff c A   (T)/2, i.e., the fear of hold-up can make the application-maker firms reluctant to bid stage 1: the payoff of first inventor  (T)/2-c B  (T)/2-c B   (T)-c A -c B iff c A   (T)/2   (T)/2   (T)/4  if the non-licensed firm invests, the profits of the first inventor reduced because of the fundamental transformation!
