patent-landscape

patent-landscape is a skill for Claude Code from K-Dense-AI/drug-discovery-agent-skills. It costs 124 tokens per session (1,925 once invoked), scanned A, original, MIT.

A research tool for checking whether chemical structures or related molecule series appear in patent documents. SureChEMBL is a searchable collection of chemical structures extracted from patents, while PatentsView can provide US legal-status and assignee information when a key is available.

In plain words
What is it for?
Use it to trace a molecule to patents, survey an assignee’s US filings, and investigate whether a chemical series may already be claimed.
Why use it?
It helps identify existing patent disclosures and see who has filed in a chemical area before investing in a project. The results support research, but do not replace legal interpretation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

patent-landscape scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/_common.py, scripts/patent_search.py, scripts/surechembl_bulk.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

The opening of the file, as written. The whole thing — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Chemical Patent Landscape

Whether a series is already claimed decides whether it is worth pursuing, and the question comes up long before anyone talks to an attorney. SureChEMBL extracts structures from patent full text, images, and attachments — over 31 million compounds from the major offices — and it is the only open, structure-searchable patent chemistry resource.

Services: https://ftp.ebi.ac.uk/pub/databases/chembl/SureChEMBL (bulk, no key) · https://search.patentsview.org/api/v1 (optional, free key). Checked against: the live bulk tree, August 2026 — 31 releases, newest 2026-08-04.

Read references/surechembl-bulk.md before downloading anything, references/patent-data-sources.md to know which source is silent about what, and references/reading-patents.md before drawing any conclusion — that one is judgement, not syntax, and the gap it describes is wide.

The two scripts

SureChEMBL has no REST API

Checked live: surechembl.org/api/ and every plausible variant return 404. The website is interactive-only, and everything programmatic goes through the EBI bulk tree.

Two directories hold different data. bulk_data/ is SureChEMBL 2.0 — Parquet plus an FPSim2 similarity index, fortnightly. data/ is the legacy quarterly txt/SDF dump whose README is dated 2016. They are easily confused and the old one is much less useful.

Pin a release. Taking "latest" makes an analysis irreproducible against a corpus that changes every two weeks.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

patent-landscape is a skill published in the GitHub repository K-Dense-AI/drug-discovery-agent-skills (28 stars, last pushed 5d ago), licensed MIT. It adds 124 tokens to every session and 1,925 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
