US 12,525,093 B2 — Evidence inventory

DraftKings measured against the Granted United States Patent

DraftKings operates a regulated real-money sportsbook alongside free-to-play and peer-to-peer contest products. Its published house rules, responsible gaming tooling and SEC filings provide unusually strong primary evidence on the wagering, settlement and account-limit limitations.

This rating reflects publicly observable functional correspondence to US 12,525,093 B2. It does not establish satisfaction of every limitation of an independent claim. 6 mandatory limitations of Claim 1 remain unestablished: C1-J, C1-K, C1-L, C1-M, C1-N, C1-O.

These categories reflect the strength of publicly identified functional correspondence with elements of the Granted United States Patent. They do not represent infringement conclusions, legal probabilities or a determination that every limitation of an independent claim is satisfied. The rating bands and how they are applied are set out on the rating methodology page.

Key disclosures

Public statements closest to the granted claim language

C1-KKey evidence

DraftKings publishes "Deposit Limits — Set daily, weekly, or monthly limits… Wagering Limits — Set limits on how much money you wager… Max Wager Limits… Time Limits."

C1-K requires limiting credits wagered during a predefined period to a defined threshold. DraftKings documents wagering limits over daily, weekly and monthly periods; the granted limitation is a service-imposed threshold and user-elected limits are recorded as partial, not equivalent.

What the Granted United States Patent expressly adds — US 12,525,093 B2

The following limitations are expressly claimed in the granted patent. They are set against what DraftKings publicly shows. Equivalent implementation has not been established from the public evidence reviewed.

A defined wagering threshold constraining credits wagered in a predefined period (C1-K).
Server-side detection of the minimal or zero-real-world-value pseudo-currency wagering condition (C1-L).
Mode-responsive reduction in the frequency and amount of real-world event updates (C1-M).
A consequent reduction in data transferred to that user across the communications network (C1-N).
Limitation of the results and related event data delivered while that condition subsists (C1-O).
