Game Theory in IP: The Power of Tit for Tat

Tik for Tat Strategy Analysis

In the complex world of intellectual property, where global stakes are high and the outcomes have far-reaching implications, the ability to negotiate effectively and collaboratively is more critical than ever. International IP firms and their clients can greatly benefit from insights provided by game theory, especially through the adoption of strategies highlighted in Robert Axelrod's experiment with the "Tit for Tat" approach.

In Robert Axelrod's experiment on the iterated prisoner's dilemma in 1980, he initially invited professional game theorists and professors to submit strategies for his experiment. In his first tournament, Axelrod received 14 different strategies. "Tit for Tat" emerged as the winner in this initial round. Encouraged by the results, Axelrod organized a second tournament to which he received 64 entries. Once again, "Tit for Tat" was the winning strategy, reinforcing its effectiveness in maintaining cooperative and non-exploitative interactions over time.

In his study, Axelrod discovered that "Tit for Tat," a strategy of mirroring the other player's previous action, proved most effective. This approach begins with cooperation and continues to replicate the other player's last move—be it cooperative or competitive.

This strategy's beauty lies in its simplicity and its foundation in collaboration, making it ideal for the collaborative environment of international IP practice. Initially extending cooperation can set a constructive tone, signaling trust and a readiness to collaborate. If the counterpart reciprocates with cooperation, this mutual approach can lead to fruitful, long-term partnerships, enhancing innovation and shared success. However, if one party chooses a competitive move, mirroring this action serves as a natural safeguard, maintaining balance and protecting interests without escalating the conflict.

Yet, Axelrod's findings also caution against the potential drawbacks when applied rigidly. Misunderstandings or confusions might lead to disproportionate reactions if the "Tit for Tat" response is not contextualized. Therefore, while the strategy champions cooperation, it underscores the necessity for clear communication and careful interpretation before reacting—key in avoiding unnecessary disputes and fostering a collaborative atmosphere.

The "Tit for Tat" strategy is clearly illustrated in the patent disputes between Apple and Samsung. Apple sued Samsung in 2011, accusing them of copying iPhone designs and technology. Samsung countered with lawsuits of its own in various countries. This tit-for-tat exchange went on until 2018, when both companies agreed to settle and drop all lawsuits outside the U.S.

From Samsung's point of view, the "Tit for Tat" strategy is evident. Every legal action from Apple received a matching response from Samsung, embodying the "Tit for Tat" principle: respond to each action equally to keep things balanced and discourage further conflict.

In 2018, when both sides agreed to settle, the balance returned to mutual collaboration. From Samsung's perspective, it responded to Apple's aggression with equivalent measures and reciprocated Apple's collaborative efforts with similar cooperation, thereby sustaining its global position. This approach exemplifies a classic "tit-for-tat" strategy in game theory.?

An interesting fact about Robert Axelrod's tournaments is that the winning "Tit for Tat" strategy was submitted by Anatol Rapoport, a mathematical psychologist. What makes this submission particularly notable is that "Tit for Tat" is a remarkably simple strategy—it cooperates on the first move and then simply mirrors the opponent's previous move.?

Despite its simplicity, it outperformed much more complex strategies in the tournaments, illustrating an important lesson: in repeated interactions, consistent reciprocity and cooperation can be more effective than more complicated or deceptive strategies. This outcome has had a profound influence on theories of cooperation and conflict resolution in various fields, including economics, political science, and evolutionary biology.
