US patent office has revoked Nintendo’s patent on summoning characters into battle

USPTO Director John A. Squires revoked Nintendo's patent by rejecting all 26 claims related to a 'summoning a character' game mechanic after a reexamination, finding the claims obvious in light of prior patents (Nintendo's Motokura 2022 and Bandai Namco's Shimomoto 2020). Nintendo missed an initial response deadline and now has a two-month (extendable) window to respond to the non-final decision; this is a legal setback for Nintendo's IP position but likely limited direct market or financial impact.

Analysis

This action raises the effective bar for patenting broad gameplay mechanics, tightening the “obviousness” threshold that portfolio managers and acquirers implicitly price into transaction models. Over the next 6–18 months expect fewer high-value, broadly-worded game-mechanic grants to survive scrutiny, which should compress expected contingent licensing pools by an estimated 30–60% for portfolios built around generic gameplay claims.

Winners are companies and platforms that compete on scale, distribution and live-ops rather than on defensive IP portfolios — they face lower tail legal costs and reduced probability of nuisance licensing demands. Second-order beneficiaries include middleware/engine providers (lower indemnity and warranty risk), publishers with heavy ongoing live-service revenues (less chance of interruption), and M&A buyers who will face smaller escrow/legal holdbacks; collectively that can free up ~1–3% of deal value previously held for IP risk in typical mid-market consolidations.

Key risks: the legal pendulum can swing back via appeal or a Federal Circuit ruling, which would reintroduce uncertainty for 6–24 months. Also, firms can respond by filing narrower, technically dense patents that are harder to challenge on obviousness — a defensive arms race that favors companies with larger patent-law budgets. Watch for litigation outcomes and patent office guidance updates as the primary catalysts that will either amplify or blunt market reaction.

Key Decisions for Investors

• Pair trade (3–12 months): Long Activision Blizzard (ATVI) + Electronic Arts (EA) overweight vs Short Nintendo ADR (NTDOY) — rationale: reduced litigation premium helps scale publishers more than IP-centric incumbents; target a 2:1 reward:risk, position-size to limit portfolio drawdown to 1.5%.
• Options trade (3–9 months): Buy U 6-month ATM calls on Unity Software (U) — thesis: lower IP litigation tail risk improves licensing/monetization prospects; aim for 3x upside if adoption/macro rebounds, cap risk at full premium paid.
• Event hedge (6–24 months): Buy protective puts on any portfolio companies with concentrated, broad-gamework patent exposure (example: NTDOY 12–18 month puts) sized to cover potential legal reversal; treat as insurance — pay ~1–2% of notional for peace-of-mind.
• M&A catalyst (6–18 months): Increase diligence appetite for mid-market game studios and platform providers; reduce assumed IP holdbacks by 100–300 bps and reprice bids accordingly to close deals where previously withheld capital blocked transactions.
