Chemistry-heavy patent PDFs, turned into reviewable scientific evidence.

Jubust extracts exemplified compounds, assay results, and example-level disclosures from patent filings — each finding anchored to its exact source page. Every answer is inspectable.

From hard patent artifacts to clean high quality machine-readable data

The bottleneck is not finding patent documents. It is reconstructing compounds, assay results, formulation details, and cross-page context quickly enough for real scientific decisions.

High-quality scientific output

Improve result quality through active learning on the fields scientists challenge, correct, and rely on most.

Current scientific review

Questions that shape real patent review.

Across competitor sets, patent families, and compound series, scientific teams need clear answers on what was made, tested, and shown. Jubust returns source-linked records they can inspect directly.
Today

What did they actually make and test — not just claim?

Which compounds were actually exemplified, which assays were run, what results were reported, and where is that shown in the source? Jubust returns source-linked compound, assay, and example records as structured, machine-readable data with provenance that a scientist can review directly.

Current scope: extracting reviewable evidence from the patent text itself.

Example 1. To a 50 mL flask was added intermediate 3 (2.3 g, 8.5 mmol) in anhydrous DMF (20 mL) under N₂. The mixture was stirred at 60 °C for 18 h. After workup and silica gel purification, KD = 97.7 nM as determined by TR-FRET binding assay for KRas G12D. Fractions were pooled and concentrated under reduced pressure to afford the title compound as a white solid (1.1 g, 47% yield).

What evidence across relevant patents should change our decision on this target?

Across the patents relevant to this target, mechanism, or lead series, which findings should affect a competitive or experimental decision? Jubust assembles a review pack with cited records across the selected filings, not just a summary paragraph.

Supported by cross-patent evidence linking.

Design-partner evaluation

Evaluate Jubust on a patent set your team already reviews.

Each evaluation is scoped around a target, competitor set, patent family, or lead series your team already reviews. The goal: see whether the output holds up in real scientific review.

Evaluation flow

01

Define the scope

Choose the target, competitor set, patent family, or lead series to review.
02

We process the filings

Jubust extracts source-linked compound, assay, and example records from the filings in scope.
03

Your team reviews the output

Scientists inspect the records, open the cited pages, and note what is usable, missing, or incorrect.
04

Decide whether to expand

If the output improves review speed and supports decisions on the set in scope, we expand. If not, we stop.

Best fit

Teams with a defined patent-review workflow

  • Medicinal chemistry teams reviewing target-specific or competitor patent sets
  • Translational research teams comparing evidence across related patent families
  • Oncology and adjacent programs where assay details and example context drive decisions

Not included

Work outside the evaluation

  • Broad document discovery or generic patent search
  • Claim interpretation, legal opinion, or freedom-to-operate analysis
  • Promises of exhaustive coverage or automated legal conclusions

Next evidence layer

More evidence unlocks harder questions.

These use cases become credible once evidence is structured and linked at scale. They sit directly above reviewed evidence packs.

Longer-term direction

A patent-native chemistry intelligence layer.

These questions become worth asking once enough reviewable evidence is structured and linked. We are not there yet, but this is the direction that justifies the current work.
Later

Where are the underexplored regions worth reviewing next?

Which parts of this chemical neighborhood appear thinly covered by current patent literature — and which nearby patents are worth deeper investigation? Framed as exploration and hypothesis generation, not definitive white-space discovery.

Common questions

What we do, how design-partner evaluations work, and where we stop.
Jubust extracts compounds and their measured assay results directly from patents, and links every datapoint to its exact source in the document so it can be verified instantly.
Search and summarisation tools stop at finding or condensing documents. Jubust is built to produce reviewable evidence packs: structured compound records, assay data, and provenance citations that a scientist can inspect and use in real decision-making — not trust blindly.
No. Jubust does not replace claim interpretation, legal status analysis, or legal opinion. The evidence packs we produce support downstream IP and FTO workflows — but the legal analysis stays with counsel.
Medicinal chemists, translational researchers, and scientific CI teams reviewing chemistry-heavy patent literature — primarily in oncology and related programs. IP and patent-intelligence teams can work from the same evidence packs, but the workflow is optimised for scientific review first.
We scope design-partner engagements around a specific patent slice your team cares about — a target, competitor, or program area. The goal is to measure whether the evidence quality and review speed hold up for real scientific decisions, not to run a generic demo.
