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. Nothing is assumed.
What scientists use Jubust for
The questions it answers.
These are not hypothetical — they map directly to the review workflows scientists run on competitor sets, patent families, and compound series. Every answer is backed by source citations you can inspect.
What did they actually make and test — not just claim?
In this patent family or competitor set, which compounds were actually exemplified, what assays were run, what results were reported, and where exactly is that in the source? Jubust extracts exemplified compounds, assay data, and example-level disclosures — each one traceable to the source page.
Direct evidence extraction from patent text. Credible with current structured output.

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 series or target?
Across the patents relevant to this target, mechanism, or compound series — what evidence supports or weakens a competitive or experimental decision? A structured review pack, not a summary. Every entry expandable back to patent source.
Supported by cross-patent evidence linking. No claim of exhaustive coverage or normalized assay comparisons.

Who is patenting compounds close to our lead series?
Which patents disclose chemistry structurally close to the series your team is working on — and what exactly did they show? This becomes available once extracted structures and scaffold linking are consistently good at scale.
Requires structural extraction at scale. Credible soon — not a current promise.

Requires structural extraction at scale — available as evidence coverage grows.
From hard patent artifacts to reviewable evidence objects.
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.

What the evidence enables
More evidence unlocks harder questions.
These use cases become credible once evidence is structured and linked at scale — the natural next layer above reviewed evidence packs.
What compound families are heating up around this target?
Which scaffold or compound families are seeing rising patent activity around this target or modality? Each trend row backed by the source patents underneath — not naked counts.
3 new filings in the past 90 days · Each row links to source patents
Which programs are starting to show cell, in vivo, or translational evidence — not just potency tables?
Which patent programs are moving beyond binding or potency claims into stronger biological or translational evidence? Evidence-type tracking, not quality assessment.
Evidence type tracking only — does not imply scientific quality or program success.
Where this leads
A patent-native chemistry intelligence layer.
These are the questions worth asking once enough reviewable evidence is structured and linked. We are not there yet — but this is the direction that makes the current work worthwhile.
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.

Coverage reflects structured evidence only. Not a definitive prior-art landscape.
What evidence links this scaffold, target, assay, and assignee across the field?
Navigate connected scientific evidence — how is this chemistry connected across patents, targets, assays, and companies? Every edge resolves back to source evidence. Not abstract network art.
