Literature & Prior-Art Search

Real publication search, not an AI summary or legal opinion. This tool queries the National Library of Medicine's PubMed database directly (NCBI E-utilities) and returns real titles, authors, journals, and abstracts. Results are ranked by a simple, visible keyword-frequency count across title and abstract text -- not a machine-learned relevance score. This is a research aid for scientific literature, not a freedom-to-operate or patent prior-art clearance opinion; formal prior-art and patent landscape work should involve a patent attorney and the structured patent tools in Patent & Exclusivity Tracker.
