Plate i. · The Question
Every patent on your desk is a bet. Size the bet.
The state of patent diligence

Patent diligence doesn't scale.

A senior associate takes a week and bills $25,000 to render an invalidity opinion on a single patent. Two seniors at the same firm often disagree on what the answer should be. Portfolios get sampled, not priced — and the patents that quietly drain budgets are the ones that never get looked at.

Trarian replaces the workup with a defensible invalidity score on every patent that crosses your desk. The unit economics of underwriting at portfolio scale, finally.

How it works

A 1–10 invalidity score on every patent.

Trained on every PTAB, Federal Circuit, and ITC validity decision we could get. The model has never seen the answer for a patent it's scoring.

What goes in

Frontier models read the patent the way an associate would — the claims, the specification, the prosecution history — and extract structured signals about the patent's standing.

Signals the model reads
— prior art on the file and in the world
— how thoroughly the examiner searched
— claim breadth and disclosure support
— novelty, obviousness, and eligibility load
— litigation and citation history

What comes out

A 1–10 score, the band's historical invalidation rate, the top weaknesses in plain English, and the closest prior art the model surfaced. Delivered as a one‑page tear sheet — or, on a portfolio, as a ranked list.

For whom

If you price a patent,
we score it.

Three underwriting desks, one signal. Built for the buyers whose unit economics depend on telling the patents worth the work from the ones that aren't.

Litigation finance

Case selection at portfolio speed.

Rank a target's portfolio or a fund's docket in an afternoon. Pass on the riskiest decile before diligence eats the budget — and put senior hours on the cases worth winning.

Patent insurance

The actuarial basis for a book of patent risk.

Underwrite infringement, validity, and verdict policies on a consistent rubric — defensible to a claims team, defensible to a reinsurer, defensible quarter to quarter.

Aggregators, brokers, lenders, owners

Know what the portfolio is worth at scale.

Defensive aggregators, NPEs, IP‑backed lenders, in‑house IP. Lead with the strongest, prune the weakest — before you pay the license, file the suit, or carry the maintenance fee.

Plate iii. · The Room
Underwriting as a craft, not a screen.
Validated on 1,296 real patent outcomes

Safest 10%: 1 in 13 invalidated.
Riskiest 10%: 7 in 8.

Sort patents by the score and look at how often each band actually got invalidated when challenged. The top of the ranking is a different patent than the bottom — by an order of magnitude.

"We rank dockets in an afternoon now. Trarian's score is the gate the riskiest patents don't get past — and the analysts spend their week on the top of the book."
