NantWorks v. Niantic — Federal Circuit Holds Pokémon Go AR Patents Invalid Under § 101

Background

NantWorks sued Niantic in 2020, asserting that Niantic’s wildly popular augmented-reality (AR) games — Pokémon Go and Harry Potter: Wizards Unite — infringed two AR patents. U.S. Patent No. 10,664,518 (the ‘518 patent) covers an AR device that uses a device’s GPS location to select a tile subarea from a map, populate that tile with relevant virtual AR content objects, and render them on screen as overlays on a real-world view. U.S. Patent No. 10,403,051 (the ‘051 patent) covers an AR platform system that determines context from device location and virtual-element attributes, identifies relevant AR objects, and causes the device to render them.

The district court in the Northern District of California granted Niantic judgment on the pleadings on the ‘518 patent, finding it directed to the abstract idea of “providing information based on a location on a map,” and then granted summary judgment on the ‘051 patent on the same grounds. Both patents were held invalid under 35 U.S.C. § 101, the provision that prohibits patents on abstract ideas, laws of nature, and natural phenomena.

The Court’s Holding

The Federal Circuit affirmed both invalidity determinations under the Alice/Mayo framework — the Supreme Court’s two-step test for patent eligibility. Writing for a panel of Judges Reyna, Schall, and Cunningham, the court agreed that NantWorks’s patents were directed to abstract ideas: specifically, determining a user’s location and displaying relevant information there, regardless of the technical-sounding elements like “tessellated tiles,” “area databases,” and “AR content objects.”

Stripping away the terminology, each step of the ‘518 patent’s representative claim could be performed with pencil and paper: identify your location in Washington, D.C.; consult a gridded map of neighborhoods; identify points of interest in your neighborhood; mark one with a sticker. The court rejected NantWorks’s argument that selective memory population — downloading only nearby AR objects to save bandwidth — constituted a technological improvement, because the claims did not meaningfully capture that efficiency benefit. The ‘051 patent fared no better; displaying context-relevant virtual objects based on device location was simply another variation on filtering and presenting location-based information.

Key Takeaways

• Patents for location-based AR systems remain highly vulnerable to § 101 challenges when they use generic hardware to implement map-and-display concepts.
• Technical vocabulary like “tessellated tiles” and “AR content objects” does not rescue claims from an abstract-idea finding when the underlying concepts reduce to basic map-grid operations.
• Efficiency benefits (reduced memory/bandwidth via selective object loading) must be specifically recited in the claims themselves, not just described in the specification, to count as an inventive concept.
• This is a significant loss for NantWorks in its ongoing effort to monetize its AR patent portfolio through litigation against gaming and technology companies.

Why It Matters

The AR gaming industry has been a patent battleground since Pokémon Go’s 2016 launch made location-based augmented reality mainstream. This ruling adds to a growing body of Federal Circuit authority holding that AR patents built around the concept of using device location to display relevant virtual content are patent-ineligible under current law. For AR developers and investors, the message is clear: the basic idea of “show me AR objects relevant to where I am” cannot be locked up by a patent, regardless of how sophisticated the implementation. Companies seeking to build defensible patent portfolios in this space need to claim genuinely new technical improvements to the underlying hardware or network infrastructure — not just novel applications of location-aware display logic.
