Why Would a Market Leader Choose Not to Patent an Innovation? Case of Samsung’s Patent Protection for Dual SIM Technology

Key Takeaways

• Samsung left dual‑SIM unpatented to expand market adoption
• Open technology created a preference‑discovery externality benefiting Samsung
• Simulations show a patent would cut Samsung’s profits despite monopoly
• Findings support strategic open‑sourcing in hardware and software sectors

Pulse Analysis

The dual‑SIM feature, once a niche capability, became a standard in emerging markets after Samsung deliberately avoided filing patents in India. This decision diverged from the typical defensive IP strategy of market leaders, opting instead for an open‑innovation model that allowed rivals to embed the technology in their own devices. By doing so, Samsung accelerated consumer exposure to dual‑SIM benefits, effectively educating the market and creating demand that it could later satisfy with its own offerings.

Economists at the Bank for International Settlements built a structural demand‑supply model on quarterly handset data to quantify the impact. Their analysis revealed a "preference‑discovery externality": as competitors rolled out dual‑SIM phones, consumers learned the value of having two active lines, which in turn raised overall market size. Counterfactual simulations indicated that a Samsung‑only patent would have stifled this learning curve, suppressing sales and reducing Samsung’s equilibrium profits despite granting monopoly rights. The open approach proved privately optimal, turning a potential IP moat into a growth engine.

The broader lesson extends beyond mobile hardware. In software, cloud services, and even automotive electronics, firms can weigh the trade‑off between exclusive control and ecosystem expansion. When an innovation’s value is largely realized through user familiarity and network effects, open‑sourcing may generate higher aggregate revenues than strict patent enforcement. Samsung’s case adds empirical weight to the argument that strategic openness can be a competitive advantage in technology‑driven markets.
