FAQ

Is Lightbringer different from a traditional patent law firm?

Lightbringer is a patent service and is not a law firm. Registered practitioners handle drafting review, filing and routine prosecution on a fixed quarterly plan.

Is Lightbringer a patent service or just an AI tool?

Lightbringer is a patent service, not just a software product. Our platform handles every step of the patent journey: from idea capture and drafting to prosecution, office action management and portfolio maintenance. AI produces the first draft. A registered practitioner reviews, edits and signs every application.

Can I trust Lightbringer with sensitive data?

Yes. Lightbringer is SOC 2 Type 2 audited, and your data is encrypted in transit and at rest. Every step from submission to prosecution is reviewed by a registered practitioner.

How does Lightbringer ensure patent quality?

Every invention goes through an AI-guided capture process. A registered practitioner then reviews the draft, checks it against what is already public and agrees the claim strategy with you before anything is filed.

Is Lightbringer only for large companies or enterprises?


Not at all. We’re built for growth-stage tech companies, from  startups to scaling tech teams. Whether you’re filing your first patent or managing a growing portfolio, our tools flex to fit your journey.
We ditch the billable hour. Instead, you get transparent, fixed pricing—so you can plan with confidence and skip the surprise invoices.

Is Lightbringer only for simple or generic inventions?

Lightbringer’s AI accelerates the drafting process, but every patent is reviewed and refined by registered patent practitioners. For highly complex domains (e.g. life sciences or deep tech), the platform pairs you with practitioners experienced in that field. The workflow still uses automation for structure and consistency, but human domain expertise always drives the final content.

Can I build a long-term relationship with a dedicated practitioner?

Yes. Every client gets a dedicated practitioner who coordinates their filings and stays with them long term, working with practitioners qualified in each jurisdiction where you file. You build an ongoing relationship with someone who knows your technology and portfolio.

Can Lightbringer manage large patent portfolios?

Yes. Lightbringer AI makes it easier to manage large patent portfolios. Our platform gives you full visibility, control, and strategic insight about your complete portfolio. From office action tracking and management to smart insights, all backed by registered patent practitioners. Lightbringer makes patent portfolio management efficient, intelligent, and aligned with your business goals.

How much does it cost to file a patent with Lightbringer?

We ditch the billable hour. Instead, you get transparent, fixed pricing, so you can plan with confidence and skip the surprise invoices. Starter is free. Pro costs $2,400 per quarter (20,000 SEK) and includes one patent draft a year, up to two patent families, office action management and a practitioner of record. Growth, for larger portfolios, several products or multiple markets, is priced on request. Official patent office fees are charged separately, and interviews, appeals and oppositions are quoted hourly. See current plans and pricing.

Does Lightbringer only cover Swedish or EU patents?

No. Lightbringer's own patent attorneys file before the EPO and UKIPO, and US filings at the USPTO are handled by a USPTO-registered practitioner. For other offices, such as Japan, we work through partner attorneys qualified in that jurisdiction, coordinated from a single point of contact.

Do I need to be a legal expert to use Lightbringer?

Not at all. Our platform is designed for founders, CTOs, and innovators, not lawyers and legal experts. When you're ready to draft an application, a real Patent Attorney from Lightbringer takes over the process.
