DraftKings has petitioned the U.S. Patent and Trademark Office to cancel a Cantor Fitzgerald patent, arguing the technology is obvious based on prior art. The legal maneuver comes as the company defends itself against an April 2026 patent infringement lawsuit filed by Interactive Games LLC.
Why it matters
DraftKings is seeking to invalidate the patent to strengthen its position against allegations that it copied protected technology for blocking bets in restricted areas. Successful cancellation of the patent claims could significantly impact the ongoing litigation filed by Interactive Games LLC.
DraftKings is challenging US Patent No. 12,406,284, which contains 18 claims related to geolocation-based betting restrictions. This move follows an April 2026 lawsuit in which Interactive Games LLC asserted a total of five patents against the company.
The players
DraftKings

Interactive Games LLC

The details

Howard Lutnick, who is identified as the lead inventor on the challenged patent, oversees the firm currently asserting these rights in court.
Timeline
In April 2026, Interactive Games LLC initiated a patent infringement lawsuit against DraftKings.
DraftKings submitted its IPR petition on September 17, 2026.
Market Landscape
The petition follows a pattern established by the America Invents Act's Inter Partes Review process, where tech firms frequently challenge the validity of asserted patents during active litigation. This defensive strategy reflects a broader trend of companies using administrative tribunals to neutralize patent-based threats in the competitive gaming sector.
For the average DraftKings user, this legal battle does not immediately change account access or the platform's betting services. However, the outcome of this dispute could influence the company's long-term operational costs and available features in restricted regions.
The takeaway
Patent challenges at the PTAB are becoming a standard defensive tool for major tech and gaming platforms facing aggressive litigation. Investors and users should monitor these proceedings as they can determine the future viability of specific proprietary features.
