Shadow of Mordor’s nemesis system now successfully patented by WB Games

The application finally went through this week

The nemesis system created in-game rivalries between you and a range of NPC opponents

After several failed attempts, WB Games has managed to successfully patent its nemesis system from Middle-earth: Shadow of Mordor and Middle-earth: Shadow of War. The most recent application goes into effect later this month, solidifying the mechanic as WB Games’ sole property.

An issue notice from the US Patent and Trademark Office (ta, IGN) states that from February 23, 2021, Warner Bros. will effectively own the nemesis system through to 2035. The filing itself uses very specific language – “nemesis characters, nemesis forts, social vendettas and followers in computer games” is just the start – to outline exactly what WB Games has domain over.

Essentially, the nemesis system is an algorithmic way of creating and deploying enemies for you to battle that remember every time they encounter you. These antagonists have personalities, and maintain themselves in a ranking system that shifts every time you fight one. It’s one of the most lauded features of WB Games’ recent Middle-earth action-adventure games, helping cultivate a dynamic world between the two open-world games that makes exploring feel worthwhile and unpredictable.

Warner Bros. has been trying to get this patent since at least 2015, failing numerous times due to bureaucratic requirements that demand specificity, or being too similar to other trademarks from companies such as Square Enix. This going through means that anyone who wants to procedurally-generate their sub-bosses in anything resembling the nemesis approach may need to talk to WB Games first.

We’ll see what effect this has on upcoming games in the years to come. If this has you considering jumping back into either game, Shadow of Mordor’s servers have been shut down, but single-player is still live and kicking. In other corners of Tolkien’s universe, The Lord of the Rings Online is due a visual update in the near future, and someone modded the entire realm into Crusader Kings 3.
