One Search Bar, Every Jurisdiction
Avoid switching between USPTO, EPO, WIPO, Google Patents, Lens, and clinical-trial databases. Search patents, assignees, claims, molecules, and trial signals from one workflow, across 120M+ patents and every jurisdiction.
Keyword
Full-text search across titles, abstracts, and claims, with hyphens and stop words handled for you.
Title and Abstract
A faster, scoped search for when you want precision over recall.
Claims
Search the claim language itself to find what a patent actually protects.
Inventor
Every filing by a named inventor, with name-order variations matched automatically.
Applicant
Search by company or assignee, with corporate suffixes (Inc., Ltd., GmbH) normalized.
Publication Number
Jump straight to a patent by number in any format, spaces and kind codes handled.

Drug-Discovery Intelligence
Every Patent, From Molecule to Clinic
Pharma-relevant patents pick up a layer of chemistry and clinical context that generic patent search never shows, drawn from the same databases the field already trusts.
MoleculePatent FamilyAssigneeClinical TrialCompetitive Landscape
Compound Chemistry
Compounds disclosed in a patent are resolved to a canonical structure: a 2D depiction plus InChIKey, IUPAC name, SMILES, molecular weight, and cross-database IDs (PubChem, ChEMBL, CAS, DrugBank).
Substructure Search
Every pharma patent is back-linked to the compounds it discloses. See how many a patent covers, then find every other patent disclosing the same molecule or scaffold, the substructure-aware search premium tools charge a fortune for.
Clinical Trial Landscape
Linked trials from ClinicalTrials.gov show phase, status, sponsor, and indication, so you can see what is in clinic for a molecule and who is running it, right beside the patent.

Patent Search Questions
What the free search covers, and what a work email unlocks.
Yes. You can search 120M+ patents across every jurisdiction for free, with no account. Signing in with a work email unlocks full-text claims, CSV export, and more results per page, but the core search and the compound and clinical-trial intelligence are free to use.
No. Anonymous search covers titles and abstracts across all jurisdictions and shows disclosed compounds and linked clinical trials. You only need to sign in with a work email when you want full-text claims or to export results to CSV.
Yes. Alongside keyword and claims search, you can search by inventor and by applicant or assignee, then narrow any query by jurisdiction, filing date, and IPC or CPC classification. Every result carries its legal status, so granted patents are easy to tell from pending applications.
Yes. Compounds disclosed in a patent are detected and rendered as 2D structures with their InChIKey, IUPAC name, SMILES, and molecular weight. From any compound you can find every other patent that discloses the same molecule or scaffold.
Yes. The enrichment layer is built for pharma and biotech work: disclosed compounds are rendered as 2D structures with full chemical identifiers, and patents are linked to their clinical-trial landscape. Non-pharma searches behave exactly the same, they simply do not pick up the chemistry overlay.
Patents are linked to trials from ClinicalTrials.gov, showing the trial phase, recruitment status, lead sponsor, and indication. This lets you see, at a glance, what is in clinical development for a molecule and who is running it.
Yes. Signed-in work-email users can export search results to CSV for sharing with IP or R&D teams, alongside full-text claims and a higher per-page result count.
It is well suited to it. Universal coverage, substructure search, assignee and inventor search, and the linked clinical-trial landscape make competitive-landscape and freedom-to-operate scoping fast. For formal work, results flow into the full Design Your Invention platform, where prior art is saved with an immutable audit trail.
The search corpus covers 120M+ patents spanning every jurisdiction and IPC class, sourced from the Google Patents public dataset via BigQuery. Coverage is universal, not limited to a single field or country.
Beyond keyword search, every result is enriched: compound chemistry with 2D structures, substructure search to find all patents disclosing a scaffold, and a linked clinical-trial landscape. You can save patents to a portfolio, export to CSV, and move straight into a full IP management platform whose in-app prior-art search is powered by Lens.org.
You can search without creating an account, and anonymous searches are not tied to a personal profile. When you sign in, your saved patents and portfolio are private to your account. The wider platform is built for confidential invention workflows with audit-grade access controls.
Compound and trial data is drawn from established scientific sources: PubChem and SureChEMBL for compound chemistry, UniChem for cross-database identifiers, RDKit for structure depiction, and ClinicalTrials.gov for the trial landscape.
Start with a free keyword, assignee, inventor, patent-number, or chemical-structure search to map the existing art, then save the relevant patents. Those saved references carry into the full Design Your Invention platform, where AI drafting generates claims positioned to be novel over exactly that prior art, against a frozen, auditable snapshot of what was reviewed.
Yes. The corpus spans every jurisdiction, including Indian (IN) patents alongside US, EP, WO, CN, JP, KR, and the rest, sourced from the Google Patents public dataset via BigQuery. You can filter any query by jurisdiction, and a free anonymous search already covers titles and abstracts worldwide; signing in with a work email adds full-text claims and CSV export.
