A patent search tool for researchers, next to the literature

Look up granted US patents through USPTO PatentsView in Official Sources, free, and read them beside the scientific papers on the same idea. For research and background, not for a patentability or freedom-to-operate opinion.

The Free plan has 45 credits a month. Patent lookups in Official Sources and paper search are free; a Deep Research Summary answer costs 1 credit and a Deep report 15.

A patent search tool for researchers should put patents next to the papers, because the same idea often appears in both. AI for Research looks up granted US patents through USPTO PatentsView in Official Sources, free of charge, and searches 250M+ scholarly works for the literature on the same technology. You see who patented what and when, and what the science says, before you talk to your technology transfer office or a patent attorney.

It is a research tool. Nothing here is a patentability, validity or freedom-to-operate opinion; a registered patent attorney or patent agent decides those.

Only US patents are covered. The EPO, WIPO and other offices are not searched, and patent families and legal status are not shown. Westlaw, Lexis and other case-law databases are not searched.

Tools for law and patents

A useful habit is to run the same idea twice: once as a patent lookup and once as a literature question. Inventors often publish before or after they file, and a paper can explain a method that the patent claims only in legal language. Keep both in the same project so the evidence stays together.

The Technical research workbook is in Workbooks. Its patent section records what you read in a patent; it says plainly that the record does not determine validity, infringement or freedom to operate.

A worked example

Example (invented for illustration): a postdoc in materials engineering has a new coating for medical implants and a meeting with her university's technology transfer office next week.

  1. In Official Sources she searches PatentsView for antibacterial implant coatings granted in the last ten years and notes 14 US patents, with their assignees. 0 credits.
  2. A Deep Research Summary answer on "which antibacterial coating approaches for titanium implants have been tested in animal studies?" cites nine papers. 1 credit.
  3. A Deep report on silver-based versus peptide-based coatings, for the background section of her disclosure form: 15 credits.
  4. She records five of the closest patents in the Technical research workbook, each with the claim number and the passage she read. 0 credits.
  5. She brings the patent list, the papers and her notes to the technology transfer office. Their patent attorney runs the formal search, including European and international filings, and advises on patentability.

Total: 16 credits, inside the Free plan's 45 a month.

Citation styles and reporting standards

Legal writing in the US mostly uses the Bluebook, and in the UK OSCOLA; the editor formats references in 10,000+ citation styles. Cite a US patent by its number, title, inventor and issue date, and note the date you checked it. In a technical paper, patents are cited like any other source in the journal's style.

What it does not do

  • It gives no patentability, validity, infringement or freedom-to-operate opinion, and no legal advice of any kind. A patent attorney or agent decides.
  • It searches US patents only: no EPO, WIPO, JPO or CNIPA, no patent families and no legal status.
  • It is not a complete prior art search. Prior art also includes non-US filings, products, theses and other public disclosures.
  • It does not draft patent claims or file applications.
  • It does not search case law, statutes or legal databases such as Westlaw or Lexis. Legal scholarship comes through the normal paper sources and the Web source.

Questions

More in the help center.

Which patents can I search?

US patents, through USPTO PatentsView in Official Sources. Patents from other offices, such as the EPO, WIPO (PCT applications), the JPO or CNIPA, are not searched, and patent families and legal status are not shown. For those, use Espacenet, PATENTSCOPE or a commercial database, or ask a patent information professional.

Can I use this for a prior art search?

You can use it to start one: to see which US patents and which papers describe an idea, so you know the field before you talk to your technology transfer office. It is not a complete prior art search. Prior art includes non-US patents, applications, papers, theses, products and public disclosures in any language, and a formal search is done by a professional searcher.

Can it tell me whether my invention is patentable or whether I can use a patented technology?

No. AI for Research gives no patentability, validity, infringement or freedom-to-operate opinion. Those depend on the claims, the full prior art and the law of each country. A registered patent attorney or patent agent decides.

Does it search case law or legal databases?

No. Westlaw, Lexis and other case-law databases are not searched, and there is no source for statutes or court decisions. Legal scholarship, such as law review articles indexed in OpenAlex and Semantic Scholar, comes through the normal paper sources, and the Web source can find public pages. Nothing here is legal advice.

What does a patent lookup cost?

Nothing. Official Sources lookups cost 0 credits on every plan, including Free. A Deep Research answer on the literature costs what its depth costs: Summary 1 credit, Deep 15, Detailed 45 on paid plans.
