IP Due Diligence for Investors — Know the Risks Before You Sign

If you're investing in Physical AI, deep-tech, or biotech, you need to know the IP before you sign the term sheet.

In these deals, the patent portfolio is the moat. Lightbringer gives you a structured, investor-ready IP report in 48 hours — so you can price the round, shape the terms, and walk in knowing exactly what you're buying.

The problem

You wouldn't wire capital without financials. You shouldn't wire conviction without IP.

Most investors sign term sheets with nothing more than a pitch-deck slide claiming "strong IP protection." By the time formal diligence catches a weak claim, a missing assignment, or a third-party patent blocking the core product, the price is set and the leverage is gone.

Traditional IP diligence doesn't fit pre-term-sheet timelines. A patent attorney engagement takes weeks, costs five figures, and produces a legal memo written for lawyers. Founders hate it. Partners skip it. Deals close on vibes.

Lightbringer closes that gap.

How it works

Three steps. 48 hours. One report that changes how you negotiate.

1. Submit the target
Provide the company name and core technology area. Optionally add patent numbers, product descriptions, or domains. Two minutes of input.

2. AI-powered analysis
Lightbringer searches patent databases, trademark registers, and third-party IP landscapes across major jurisdictions — US, EU, UK, and beyond. Every filing, assignment, and freedom-to-operate signal is mapped and weighted.

3. Receive your report
A clear, investor-ready report covering IP portfolio summary, identified red flags, trademark status, and infringement risk signals. Delivered in 48 hours. Readable on a plane ride.

What you receive

A structured view of the prospect's IP position — written for investors, not attorneys.

• IP asset inventory. Every patent and trademark tied to the target, with filing status, jurisdictions, and expiry.

• Portfolio quality indicators. Strength, scope, and coverage scored against the company's stated technology focus.

• Ownership and chain-of-title signals. Who actually owns the IP, and whether assignments line up with the cap table.

• Third-party infringement risk. Overlapping patents held by others that could block, constrain, or sue.

• Red flag summary. Each issue tagged with a severity indicator, so you can skim in minutes and dive deep where it matters.

Clear. Concise. Actionable.

FAQ

Is this a substitute for legal due diligence?
No. Lightbringer gives investors a pre-term-sheet screen so you can decide whether to proceed, and on what terms. Once you're in exclusivity, your counsel runs formal legal diligence. Think of Lightbringer as the diligence you do before the diligence.

How is the report delivered?
As a PDF, within 48 hours of order. Each section is structured for skimming, with red flags surfaced at the top.

What if the target has no patents?
That's a finding in itself. The report covers trademark status, visible IP strategy, and third-party risk regardless of whether the target has filed anything. "No patents" in a deep-tech company is a red flag — and we'll explain why.

Do you need the founder's cooperation?
No. The report uses available patent and trademark data. You can run it before making an offer, without tipping the target.

Can I share the report with my LPs or IC?
Yes. It's structured to slot into an investment memo without rewriting.

Your next deep-tech deal closes in weeks. Your IP view arrives in 48 hours.
