The Prisoner's Dilemma of Licensing: Collaborate or Litigate?

By: Amer Al-Nasser/ AGIP Nordic

When two companies each hold valuable patents the other needs, they face a choice: should they collaborate by licensing technology to each other, or take their chances in court? This situation often mirrors the classic prisoner’s dilemma from game theory, a scenario in which two parties acting in their own self-interest can end up worse off than if they had cooperated. In the world of intellectual property, the “prisoner’s dilemma of licensing” can lead firms to stockpile patents and sue, even when cooperation would benefit everyone.

A High-Stakes Game of Trust
Imagine two rival tech companies, A and B, each developing a new smartphone. Each owns patents on important features. Company A has a patent on a novel camera technology, while Company B holds patents on advanced battery tech. Both could benefit from using each other’s innovations: the best phone would have both a great camera and a long-lasting battery. Now they have two basic options: collaborate (license patents to each other) or litigate (refuse to license and potentially sue if the other uses their tech).

It’s a high-stakes trust game. If both companies collaborate and cross-license their patents, each can produce a superior product and avoid costly lawsuits. Consumers get better devices and the companies save on legal bills. However, if one side offers to license (cooperate) while the other side defects and litigates, the defector gains a big advantage. For instance, if Company A shares its camera tech but Company B refuses to license its battery and instead sues A for infringement, Company B could cripple A’s product or extract large damages. The cooperative company ends up the loser. Because of this risk, both might be tempted to play it safe and not cooperate.

What if both choose to litigate and hold out? Each firm will try to block the other. A threatens B over camera features, B countersues over battery patents. The result: a legal deadlock or a delayed product, and millions spent in court. Often, after years of fighting, they end up settling or cross-licensing anyway, but only after incurring heavy costs. This is the lose-lose outcome, akin to both prisoners staying silent and getting harsh sentences in the classic dilemma.

Patent Arms Races and “Mutually Assured Destruction”
This dynamic has played out in real life. According to a Yale University interview with economist Stefan Wagner, the smartphone industry in the 2010s became a patent arms race. A prisoner’s dilemma where “everyone has an incentive to have the biggest patent portfolio.” Each company feared that if it didn’t accumulate patents, a rival would gain an upper hand. A vivid example was Google’s situation with Android: Google entered the mobile phone arena with relatively few patents of its own, while competitors like Apple and Microsoft had huge patent libraries. Faced with the threat of litigation that could hobble Android, Google made a dramatic move, it bought Motorola’s mobile division in 2011 primarily to acquire its 17,000+ patents. This defensive acquisition was essentially Google arming itself with patents so it could deter lawsuits or strike back if sued. In game theory terms, Google defected from pure cooperation to ensure it wouldn’t be the lone loser without weapons in a world where everyone else was ready to litigate.

Big companies also engage in a form of détente: mutually assured destruction. If each tech giant holds thousands of patents, any lawsuit can be met with a counter-lawsuit. Knowing this, many firms choose to sign cross-licensing deals, effectively agreeing to share technologies and not sue each other. It’s the cooperative solution that avoids mutual ruin. For instance, throughout the tech industry, there are extensive cross-license agreements (IBM alone has cross-licensed with countless companies for decades). These agreements allow innovation to proceed without constant fear of a lawsuit from a competitor holding an essential patent.

Conclusion 
The “collaborate or litigate” decision is a delicate balancing act. Each company must weigh short-term self-interest against the long-term consequences of a patent war. The prisoner’s dilemma teaches us that when trust is low, everyone might choose to fight, but both can end up worse off. Forward-looking companies try to break this cycle by building trust, through cross-licensing, alliances, and clear ground rules, so that collaboration becomes the winning strategy for both sides. In the end, a cooperative approach to licensing can spark more innovation and market growth, whereas constant litigation often means everyone loses time, money, and goodwill.
