News: Lightbringer raises $10 million in Series A funding

Industries / Climate tech

Climate tech patents that

turn science into leverage

Long development cycles, capital-heavy scale-up, and licensing as a business model. Climate tech needs patents more than almost any sector, and can afford hourly legal fees less. Lightbringer fixes that.

The moat matters more when the timeline is long

Climate tech runs on a different clock. A battery chemistry, a catalyst, or a capture process can take a decade to reach industrial scale. In that time, incumbents notice, researchers publish adjacent work, and the competitive landscape fills in.

Tree problems we see:

Filing once, then stopping.

The first patent covers the lab result. The value is in the scale-up: the process improvements, the manufacturing method, the integration. Each is a filing. What patent portfolio strategy looks like.

Ignoring the licensing case.

Many climate tech companies won't manufacture at scale themselves. If your model is to license to an industrial partner, the patent is the product. It needs to be drafted like one.

Discovering the cost problem mid-raise.

Hourly legal fees scale with complexity, and climate tech is complex. Founders find this out when the invoice arrives during due diligence.

Cleantech patents across the energy transition

Energy storage and generation

Battery chemistries, supercapacitors, hydrogen systems, solar and wind components, and power electronics. Composition, cell design, and manufacturing method claims.

Carbon capture, removal, and utilisation

Sorbents, direct air capture systems, mineralisation, and CO₂-to-product pathways. Process claims that hold as you scale from pilot to plant.

Grid, software, and energy systems

Grid management, demand response, energy trading algorithms, and building energy optimisation.

Materials and industrial decarbonisation

Low-carbon cement, green steel processes, bio-based materials, and circular manufacturing. Where the invention is a process, and the process is the business.

From pilot to portfolio

01

Disclose the breakthrough

Describe the invention in plain language, attach the data. Our agentic AI structures the disclosure and runs a novelty search across existing patents and literature, including the academic prior art that climate tech is heavy on.

02

Set the strategy with your attorney

A dedicated patent attorney maps what to claim now, what to hold back for a later filing, and where to file given your manufacturing and licensing plans. AI does the heavy lifting. The attorney handles judgement. Patent strategy on Lightbringer

03

Build the portfolio as you scale

Each scale-up milestone can generate new filings. Your portfolio, deadlines, competitor activity, and office actions live in one platform, so the fifth patent costs the same as the first and your team spends time on the technology.

Patents priced for a long journey

Flat fee, planned in advance

$7,200 per patent application per year covers strategy, drafting, filing, and prosecution to a decision on grant. Official fees are the only extra. Model your IP budget for the next three years and know it holds.

International patent costs explained

Attorneys who understand energy and regulation

Our team has drafted across renewable energy, carbon capture, biomaterials, and circular systems. Every patent is reviewed and approved by a qualified patent attorney who knows the regulatory landscape your technology lives in.

What we do for energy and cleantech companies

A portfolio built for licensing and diligence

Investors, grant bodies, and industrial partners all ask the same question: what do you own? Lightbringer gives you a live view of your patent estate, competitor filings, and upcoming deadlines you can share without a scramble.
