We Provide IP Certainty for AI Content Moderation Platforms Through Licensing
If your platform uses machine learning to analyse, score, and automatically moderate visual content, your system may practise our granted patent claims.
The Legal Framework
Lighthouse Technologies Limited holds granted patents (priority date: December 21, 2020 | granted: 2023-2025) covering methods for automated moderation of visual content using machine learning to analyse images and video, generate confidence scores, and apply threshold based enforcement. Operating methods covered by granted patents without a licence may constitute infringement.
Covered Jurisdictions
17 jurisdictions representing 53% of global GDP:
Patent infringement, where established, carries significant legal and financial consequences. We encourage proactive licensing discussions.
Platform Operators
Operating AI moderation platforms that practise patented methods without a licence may constitute direct infringement.
Directors
UK case law indicates directors may face personal liability where infringement continues after notice (Lifestyle Equities CV v Ahmed).
Enterprise Customers
Deploying vendor platforms that practise patented methods may create end user exposure. Vendor indemnification may not cover third party IP.
Understand your IP position. We welcome licensing discussions.
The Full Scope of Operating Risk
Operating without proper IP coverage creates cascading business consequences across your organisation, investors, and enterprise customers.
Chain Liability
If infringement is established, liability flows through the supply chain.
Both suppliers and end users may be held jointly liable. Enterprise customers demand IP indemnification, but vendors cannot indemnify for rights they do not hold.
Director Liability
Personal exposure where infringement is established.
UK case law (Lifestyle Equities CV v Ahmed) demonstrates that directors may face personal liability where infringement continues after notice. Corporate structures do not always provide protection.
Investor Impact
Unresolved IP risk blocks fundraising.
Investors conducting due diligence identify IP exposure. Unresolved patent risk is a deal-breaker. VCs require clear IP ownership or licensing. Raising Series A/B with known patent disputes creates disclosure obligations.
Operational Disruption
Injunctive relief can halt commercial activities.
Where infringement is established, courts may grant injunctions preventing new sales, freezing revenue pipelines, and affecting existing contracts. Operations may be disrupted during dispute resolution.
Reputational Damage
Enterprise customers require vendors with clear IP positions.
Major brands conduct IP due diligence before procurement. Competitors may leverage unresolved IP questions. Market credibility can be affected, impacting fundraising, partnerships, and procurement decisions.
Cost of Inaction
| Scenario | Licensing Fee | Litigation Costs | Business Disruption | Total Risk |
|---|---|---|---|---|
| Licensed Operations | Transparent Annual Fee | £0 | None | Low |
| Unlicensed Operations | £0 (Initially) | £500K - £2M+ | Cannot sell/renew contracts | Catastrophic |
Enterprise Buyers: Vendor IP Exposure May Be Your Exposure
When you deploy a content moderation platform in any of our 17 covered jurisdictions, you implement a technical method. If that method practises our granted patent claims, your organisation may have exposure, regardless of your vendor's indemnification clause.
Vendor indemnification may not cover third-party IP rights.
If your vendor lacks proper IP coverage, your use of their technology may create exposure. Courts may grant injunctive relief and damages where infringement is established.
Your Vendor's Status Determines Your Exposure
IP due diligence is essential. We can help verify coverage.
Procurement Verification
The only questions your procurement team should ask:
- 1.Does your vendor hold patents or licences for the methods you're deploying?
- 2.Can they provide documentary proof from the patent office?
If the answer is “no” or “we’re not sure”, we recommend verifying your IP position.

Licensing Enquiries
We invite platform operators and their counsel to discuss licensing terms tailored to your specific deployment scale and jurisdictional footprint.
All prelicensing discussions and technical audits are conducted under strict NDA. Your deployment details remain confidential.
Our licensing team responds to all commercial enquiries within 2 business days. Urgent infringement matters handled same day.
FAQ
Clear answers about our open source technology, patent coverage, licensing terms, and IP considerations.
What exactly do your patents cover?
Our patents cover the foundational methods for AI powered content moderation: machine learning analysis of visual content, threshold based filtering decisions, and automated blocking or redaction based on both content ratings and confidence scores with configurable restriction parameters.
Is Redax open source?
Yes. We are releasing our browser extension, content moderation SDK, edge workers, mobile apps, desktop apps, and school system as open source. Thirty repositories covering years of R&D. The models, the applications, and the infrastructure code. All will be published on GitHub under permissive licences.
How does on-device moderation work?
When you add our SDK script tag, the content moderation model downloads to the user's device on first visit and caches locally. All inference runs on the user's device. No images or video are sent to any server. It works offline after the initial download. Sub-50ms latency, zero data collection.
Does the SDK collect user data?
No. The entire point of on-device moderation is that nothing leaves the browser. No images are uploaded. No API calls are made during moderation. No analytics, no tracking, no telemetry. The model runs locally and the results stay local. Privacy by architecture, not by promise.
Can I use the free tools commercially?
Yes. The open source tools are released under permissive licences for both personal and commercial use. If you're using our provided tools and SDK, you're covered. Licensing discussions apply to commercial operators who build their own independent implementations of our patented methods.
How do I know if I need a licence?
If you use our open source tools, you don't need a separate licence. If you've built your own content moderation system that practises our patent claims without using our tools, we should talk. We can review your implementation confidentially under NDA.
What jurisdictions are your patents granted in?
We hold granted patents in 17 jurisdictions: United States, United Kingdom, and 15 European countries (via EP validation) including Germany, France, Italy, Spain, Netherlands, Sweden, Switzerland, Norway, Ireland, Austria, Belgium, Denmark, Finland, Luxembourg, plus South Africa, covering 53% of global GDP.
I'm an enterprise customer. Why should I care about my vendor's patent status?
Patent infringement is strict liability. Intent is not required. If your vendor lacks proper IP coverage, you may have exposure when deploying their system. Vendor indemnification clauses may not cover third-party IP rights. Procurement teams benefit from verifying IP coverage before deployment.
What happens if I'm already operating without a licence?
Contact [email protected]. We work with platforms to establish appropriate coverage based on deployment scale and revenue. Proactive licensing is significantly more favourable than responding to enforcement actions. Initial response within 2 business days, urgent matters same day.
How is licensing priced?
Licensing fees are structured by company size, deployment scale, jurisdictional coverage, and revenue from covered methods. Transparent pricing from £12K annually for startups to custom enterprise agreements. Each situation is evaluated individually. Contact our licensing team for a specific quote.
We built our system independently. Do we still need a licence?
Potentially. Patent infringement is strict liability regardless of independent development. If your technical methods practise our granted patent claims, licensing may be required. However, if you switch to our open source tools, that resolves the question entirely. We recommend a confidential technical review.
How can I verify your patent coverage?
All our granted patents are publicly searchable. View the full patent family at WO2022137077A1 on Google Patents or Espacenet. We provide detailed claim mapping and infringement analysis under NDA during licensing discussions. Priority date: December 21, 2020. Grant dates: 2023-2025 across all jurisdictions.
