Patent research
Describe a technology in a few words, add optional context and filters, and Patent Finder builds the query, scores candidate records for relevance, and lists matching patents with their office, dates, abstract, and source link.
Sign-in required. Free shows the top 10 matches; Premium scores the full candidate pool.
Overview
Patent Finder is an AI patent search workspace for researchers who need to see how a technology appears in patent records, not only in journals. You describe the problem in plain language; the tool turns it into a Boolean query, retrieves candidates from a corpus covering six patent offices, and labels the candidates it scores so that only Relevant and Partial (high) matches reach your list. Use it as a patent search tool for literature reviews, the background section of a proposal, a technology scan, or an early look at which companies and inventors are working on an idea. Every result keeps its publication number, office, inventors, assignees, and a link to the source record, so you can verify anything you cite. It does not assess legal status, validity, or patentability.

Enter a topic of 2 to 30 words, optionally with a 5 to 400 word description and comma-separated extra terms. Patent Finder builds a Boolean query from them and shows it with your results, in full on Premium, so you can see what was searched. If a strict query finds too few candidates, the search drops a term group to broaden it and tells you which group was removed.
Limit a search to any of the six offices in the corpus (CN, US, JP, EP, KR, and WO for PCT applications) or leave the field empty to include all of them. Inventor, assignee, and publication-year fields narrow the request before it runs; the results panel then filters loaded records by keyword, relevance, office, year, inventor, and assignee.
Each listed patent shows its AI relevance label, publication number, office, publication and filing dates, inventors, assignees, and abstract, plus matched concepts and classification codes where available. Filings of the same invention are grouped on one card, and machine-translated records name their original language. Export the filtered view or every loaded result as a CSV file.
How it works
Write the topic as a technical phrase: the mechanism, material, or function you are studying rather than a brand name. Add a short description or alternative terms if your field uses several names for the same idea, then set any office, inventor, assignee, or year limits.
The search runs in stages and streams scored records as they become ready, with live counts of relevant, partial, and irrelevant candidates. When it finishes, check the generated query, read the abstracts, and open the source record for any patent you plan to rely on.
Narrow the list by keyword, office, year, inventor, or assignee, then export the filtered view or the full result set as CSV. Your most recent searches stay in the history panel, so you can reopen a result set without running the search again.
Inputs, outputs & coverage
Patent Finder is built for research discovery: seeing which inventions, organizations, and inventors are active around a technical topic. These are its practical boundaries.

Frequently asked questions
Short answers about coverage, filters, record access, and how to read Patent Finder results.
Contact our teamPatent Finder searches records from six offices: China (CNIPA), the United States (USPTO), Japan (JPO), Europe (EPO), South Korea (KIPO), and international PCT applications published by WIPO. Select one or more offices in the search form, or leave the field empty to include all six. After results load, you can also filter the list by office. Other national offices are not part of the corpus, and the tool does not guarantee that every publication from these six offices is present, so confirm important records in the office's own register.
Yes. The search form has separate Inventor and Assignee fields, so you can follow a research group or a company within your topic. Once results load, the advanced filters list every inventor and assignee found in that result set, with a count for each, and let you select several at once. Names are tidied for consistent display, but patent records can spell the same person or organization in different ways, and some records do not disclose an inventor or assignee at all.
Each result card shows the title, parties, dates, and abstract that Patent Finder holds for that record. When a record has a source link, use View Patent to open it and read the full document, such as its claims and description. Grouped filings of the same invention can link to their own records. The CSV export includes each patent's URL, so you can return to the sources later. What a source page shows depends on the site that hosts it.
No. Patent Finder helps you discover patent records that relate to a research topic, and its Relevant and Partial (high) labels are AI judgments rather than legal analysis. It does not assess novelty, validity, legal status, infringement risk, or freedom to operate, and a result list is not a complete prior art search. Use the records to understand a technology landscape, then read the original documents. For filing or commercial decisions, work with a qualified patent attorney or agent.
