01 — Cost

We hired the patent attorneys.
We just fired the billable hour.

One fee covers the work, and every application is still drafted and signed by an experienced patent attorney. Ask as much as you like — the number does not move.

$600 per application, per month
  • Drafting and filing
  • Full prosecution to grant
  • Every office action
  • Foreign attorney fees
  • Questions. All of them.

Billed annually at $7,200 per application. Official filing fees are set by each patent office and billed at cost.

02 — Visibility

Full transparency, from disclosure to grant.

Every application, every deadline, every office action in a single view that stays current — updated as it happens, not when someone gets round to writing it up.

Nobody has to be emailed to find out where things stand. And nothing you ask shows up on an invoice.

03 — Strategy

Know what to file.
And what to skip.

A traditional engagement is transactional. You bring an invention, they draft it, you pay for it. Nobody asks whether it was the right thing to protect — which is how founders end up with a pile of patents instead of a moat.

Lightbringer reads what you have already built, finds what is patentable in it, watches what is being filed around you, and turns that into a strategy your attorney shapes with you.

Having everything in one place makes it so much easier, especially knowing that everything is quality-checked by both a human and AI.

Every application is drafted, reviewed and signed by an experienced patent attorney. The AI does the assembling, the searching and the watching. A human decides what your claims say.
