Missing data is not just inefficient. It's a risk.

Hidden data in hundreds of pages

Relevant activity is buried in tables, figures, examples, and attachments.

Inconsistent units and assay conditions

Different units, formats, and assays make comparison risky.

Broken context from cross-references

Important details are spread across claims, examples, and figures.

Missing values lead to wrong conclusions

One missed value can invalidate priorities and decisions.

Manual review is slow and error-prone

Teams spend days extracting and still miss data.

Patent search stops too early.

Most tools help teams find documents. Jubust turns patent PDFs into verified, source-linked SAR datasets your scientists can trust and analyze.

Extracted by pipeline. Verified by humans.

Our pipeline extracts compounds, assay values, and source locations from dense patent PDFs. Reviewers then verify the SAR record and can see the exact PDF location behind every value.

What you actually get

Structured SAR dataset

Structured rows with CSV and Excel export, ready for filtering, review, and analysis.

Source-linked evidence

Extracted values link back to the source page and evidence region in the patent.

Normalized bioactivity

Numeric assay values ranked and normalized to nM where units are parseable.

Expanding

Compound structures

Structure images and linked compound records, with identifier coverage expanding across filings.

Soon

Assay context

Source table labels and assay endpoints today. Cell line and method context are next.

Soon

Claim relevance

Claim mapping is planned for teams that need IP relevance alongside SAR evidence.

From patents to verified SAR in hours

1. Upload

Upload 10-50 patent PDFs around your target, disease area, or modality.

2. We extract and verify

Our pipeline extracts compounds and bioactivity. Reviewers verify every datapoint included in the delivered dataset.
