The Add2Coin Patent Explained: What It Protects and Why It Matters

On 28 March 2026, AI Administrator Limited filed patent application GB2606991.4 with the UK Intellectual Property Office. The application covers the method and system underpinning the Add2Coin advertising rewards platform — specifically, the mechanism of distributing advertising-generated value simultaneously across a multi-level attribution chain with verified engagement and blockchain settlement.

We want to explain what the patent actually says, why it was written the way it was, and what it means for anyone building in this space.

The Core Concept Being Protected

The patent does not protect "paying people to watch ads." That concept is not novel and has existed in various forms for decades. What is protected is a specific combination of technical processes that, together, constitute a genuinely new way of distributing advertising value:

• Delivering the mechanism without any installation on the user device (no browser extension, no app, no plugin)
• Verifying genuine engagement through cumulative visible time measurement that pauses when the content is not visible
• Resolving attribution across multiple levels of the chain simultaneously before any tokens are allocated
• Allocating to all present parties at once, while permanently omitting absent parties rather than redistributing their share
• Settling allocations on a distributed ledger in batches, separate in time from the event recording

The novelty is the combination. No prior system combines all five of these properties in a single unified mechanism.

Why the Language Is Technology-Agnostic

Patent claims can be written narrowly (covering only a specific implementation) or broadly (covering the concept regardless of how it is implemented). Narrow patents are easy for competitors to design around: simply change one technical detail and the claim no longer applies. Broad patents are harder to design around because they protect the underlying idea, not a specific realisation of it.

The Add2Coin patent was deliberately written as broadly as possible. The claims say "client-side executable code" not "JavaScript." They say "user agent" not "browser" or "web browser." They say "engagement parameter" not "visibility duration" or "watch time." They say "distributed ledger" not "Polygon blockchain" or "Ethereum."

This means the same protection applies if the mechanism is implemented in a smart TV app, a podcast player SDK, a mobile application, a digital signage controller, or any other runtime environment. A competitor cannot avoid the claims by implementing the same process in a different programming language or on a different platform.

The Twelve Claims in Plain English

Claim 1 (Independent Method) covers the entire process as a method: deliver code without install, verify engagement, resolve attribution chain, allocate simultaneously with absent parties receiving zero, settle on distributed ledger. This is the broadest claim.

Claim 2 (Independent System) covers the same invention described as a system of components rather than a process. Having two independent claims — one covering the method, one covering the system — means a competitor must avoid both to be safe.

Claim 3 (Deflationary Non-Allocation) specifically protects the mechanic where absent parties tokens are permanently omitted, not redistributed or deferred. This creates a deflationary effect that is novel in the advertising rewards context.

Claim 4 (Activity-Triggered Epoch Reduction) covers the halving mechanism triggered by cumulative impression counts rather than time intervals. This is fundamentally different from Bitcoin's time-based halving.

Claim 5 (Anonymous Cross-Context Attribution) covers the pseudonymous identifier that enables attribution without account creation or PII collection.

Claim 6 (Server-Side Cryptographic Settlement) covers the server-side signing approach where the settlement engine holds the private key, eliminating the need for user-held keys at settlement time.

Claim 7 (Batch Settlement) covers the single ledger instruction covering all pending recipients, independent of how many events occurred.

Claim 8 (Revenue Buyback and Burn) covers the mechanism of converting ad revenue to tokens via secondary market purchase with permanent destruction of a portion.

Claim 9 (Visibility-Based Engagement Verification) covers measuring cumulative active state duration, pausing during inactivity, as the verification mechanism. The claim explicitly states this is "independent of any specific measurement technology" — covering audio playback, proximity sensors, and other engagement measurements beyond just visual.

Claim 10 (Configurable Attribution Depth) covers any number of referral levels with configurable per-level allocation, preventing design-arounds via different chain depths.

Claim 11 (No-Install Integration) covers the single remote resource reference mechanism, directly distinguishing the system from any approach requiring browser or device modification.

Claim 12 (Hybrid Settlement) covers the two-phase architecture of immediate database recording followed by deferred ledger settlement as separate operations.

What This Means for the Industry

Any platform implementing a system that falls within these claims — delivering ad rewards without installation, verifying genuine engagement, distributing across a multi-level chain simultaneously, settling on a distributed ledger — needs to consider whether a licence is required. This includes not just new entrants building similar systems, but established platforms like Google, Meta, Amazon, Samsung, and Spotify if they add viewer reward features with attribution chains to their advertising products.

The international PCT filing, planned before the March 2027 deadline, will extend this protection to 150+ countries including the USA, EU, and China. All Add2Coin products and documentation carry the notice "Patent Pending GB2606991.4."
