DraftKings filed a petition with the Patent Trial and Appeal Board to cancel US Patent No. 12,406,284, which governs geofencing technology for blocking bets in restricted areas. The move follows a separate April 2026 lawsuit in which Interactive Games LLC accused the operator of infringing on five of its patents.
Why it matters
The outcome of this challenge could determine the operational costs and legal liabilities for betting platforms that utilize geolocation controls to meet regulatory requirements. By seeking to invalidate the patent on grounds of obviousness, DraftKings aims to resolve an active infringement claim that currently pits it against Interactive Games LLC in district court.
DraftKings is contesting 18 specific claims within US Patent No. 12,406,284 after being hit with an infringement suit involving five patents in April 2026. The petition argues the patent is obvious in light of prior art.
The players
DraftKings
A digital sports entertainment and gaming company with significant market share in the U.S. mobile betting industry.
Interactive Games LLC
A firm that asserts patent ownership and currently acts as a plaintiff in litigation regarding gambling technology.
Howard Lutnick
The lead inventor of the challenged patent and a prominent executive overseeing financial and investment services firms.
Patent Trial and Appeal Board
A federal administrative tribunal within the USPTO that adjudicates the validity of issued patents.
The details
DraftKings initiated the petition at the Patent Trial and Appeal Board to cancel the patent, which was invented by Howard Lutnick. The challenge argues that the technology, designed to block users from placing bets in prohibited geographic areas, is derived from earlier written inventions. This legal maneuver aims to neutralize the primary basis of a lawsuit filed against the operator in April 2026, while Interactive Games LLC continues to resist a separate motion to dismiss.
Timeline

DraftKings submitted its IPR petition on September 17, 2026.
Market Landscape
This petition follows the initiation of a patent infringement lawsuit in April 2026 involving five distinct patents. The challenge signals a broader industry trend where operators aggressively leverage administrative patent reviews to contest intellectual property claims during active litigation.
Operators relying on proprietary geofencing or compliance technology should audit their intellectual property defenses to identify potential overlap with existing patents. Reviewing whether your current tech stack faces similar patent validity questions can help mitigate the risk of sudden infringement litigation.
The takeaway
The patent invalidation process remains a critical strategic tool for companies looking to dismantle competitive barriers during litigation. Operators should keep a close watch on the Patent Trial and Appeal Board docket to see if this challenge sets a precedent for how betting-related location patents are enforced.
