New Nintendo Patent Threatens Diablo, World of Warcraft, and Elden Ring Mechanics

US Patent Expands On In-Game Companion Mechanics, Potential Implications for Diablo, WoW, Elden Ring, and More

Nintendo and The Pokémon Company have filed a US patent that has drawn significant attention. The patent describes a system enabling secondary characters to fight alongside a player. While this concept immediately brings Pokémon to mind, its scope is broad enough to encompass numerous other game genres. Examples include Necromancers summoning skeletons or golems in Diablo IV, pets in World of Warcraft, and ash-summoning mechanics in Elden Ring. Given that such mechanics have been prevalent in gaming for decades, many in the community are questioning the patent's potential breadth and its impact on existing or future titles. This development occurs as Nintendo is engaged in a legal dispute with Pocketpair, the creators of Palworld, regarding Pokémon-related patents in Japan. Nintendo appears poised to use legal action to safeguard its creations, and this new US patent could serve as another legal instrument in its arsenal. Even without immediate enforcement, the patent could deter smaller studios from developing games with similar summoning mechanics, primarily due to the potential for high legal fees.

Potential Impact of Nintendo's Game Mechanics Patent on Gaming Industry Innovation

This potential deterrence for smaller studios raises a significant concern within the gaming industry regarding creativity. If companies begin patenting general gameplay ideas, it could create substantial barriers to innovation. Nintendo's patent could be a precursor to a broader discussion about the patentability of core game mechanics.
