US Patent Office Rejects Nintendo Patent Involving Summoning Characters to Fight

The US Patent Office rejected Nintendo patent US12403397 after a reexamination ordered by USPTO Director John Squires, citing prior art (a 2002 Konami patent and a 2019 Nintendo filing); the rejection is non‑final and Nintendo can appeal. Nintendo and The Pokémon Company sued Pocketpair in Sept 2024 seeking injunctions and ¥5 million (≈US$32,700) each plus late damages, and Pocketpair has implemented gameplay changes (removed throwable Pal Spheres in patch v0.3.11; switched gliding to an inventory glider in May 2025) citing litigation-driven compromises. Palworld reached 25 million users within a month of Steam Early Access, but ongoing legal uncertainty is affecting product development and could continue to constrain features.

Analysis

A recent administrative/legal development that reduces the enforceability of narrowly scoped game-mechanics patents meaningfully changes how IP functions as a competitive moat. For companies that have priced part of their upside into the ability to shut down rivals via injunctions, the market should revalue the premium for litigative protection by ~150–300bp of market cap over the next 3–12 months as precedent and reexamination outcomes crystallize.

Second-order winners are platform and tooling providers that enable fast product iteration (engines, middleware, patch deployment) and pure-play live service studios because less-risky development paths lower expected compliance cost and time-to-patch; expect 6–18 month revenue tailwinds for firms with a large indie/customer base. Conversely, IP-heavy incumbents that rely on narrow patents for competitive control face a slower, multi-quarter erosion in monetization optionality — they may lean more on exclusives, brand marketing, and platform-level lock-in instead of litigation.

Key catalysts to watch: administrative appeal rulings, interim court injunctions, and developer behavior (feature rollbacks vs workarounds) observable in product telemetry — each can swing sentiment in days but will only change firm fundamentals over quarters. Tail risks include an adverse appellate ruling restoring strong enforcement (fast, immediate hit) or industry-wide licensing settlements (slower, value-recapturing outcome), so position sizing and timeboxes are critical.

Key Decisions for Investors

• Buy 3–6 month NTDOY (Nintendo ADR) puts sized 1–2% of portfolio notional — objective: capture a 10–15% move if litigation leverage is impaired; max premium loss capped; stop at 50% of premium. Catalyst window: appeal decision or major court motion in next 3–9 months.
• Pair trade: short NTDOY / long 9766.T (Konami) equal beta-adjusted notional for 6–12 months — rationale: re-priced litigation moats hurt larger, diversified IP-dependent firms more than compact IP holders or developers cited as prior art. Target spread capture 8–12%; stop if spread widens against view by >12%
• Long U (Unity) 6–12 month call spread (buy ATM, sell 20–30% OTM) sized 1% notional — way to express more organic demand from indie/live-service studios for rapid iteration tooling without paying full premium. Risk: sector macro pullbacks; reward: 2–3x upside vs premium paid if adoption accelerates.
