FreePatentsOnline search	Derwent Innovation	PatBase	Questel Orbit
Document coverage: FreePatentsOnline searches US, European (EP), Japanese (JP) and PCT (WO) documents, with Japanese abstracts and a beta German collection. Library guides note that the full-text word search applies to US patents from 1976 onward.	Document coverage: The product is now named Derwent Patent Search and is published by Clarivate. It covers documents from more than 100 patent offices and adds Derwent World Patents Index records for 50 key jurisdictions.	Document coverage: PatBase, from Minesoft, lists about 190 million publications fed from patent sources, with full text for the major jurisdictions. Original and machine-translated text can be searched together.	Document coverage: Orbit Intelligence is the patent search and analysis product of Questel. The size of its collection is not stated on the product page, so compare coverage for your target countries during a trial.
Search and analysis functions: A basic mode and an advanced mode with many fields are offered, and results can be downloaded as PDF. Free registration adds alerts and portfolios, but only for the word-searchable US documents.	Search and analysis functions: Results can be filtered, sorted and shown as graphics such as trend maps and patent activity charts, then exported to spreadsheets. The edited DWPI titles and abstracts help a non-specialist grasp the technical point quickly.	Search and analysis functions: The platform combines family-level and publication-level search, AI query expansion, relevance scoring, claims comparison and dashboards for competitor tracking, white spot detection and freedom-to-operate searches.	Search and analysis functions: Orbit offers add-on modules for chemistry (small molecules), biosequences, legal status and grant statistics. An Express edition targets simpler searching and collaboration.
Typical user and expertise: Suited to engineers and inventors who run occasional prior-art or competitor checks and are comfortable with fielded and Boolean queries.	Typical user and expertise: Aimed at professional patent searchers and information services, and offered to libraries under license. Expect to learn its query syntax and the DWPI fields.	Typical user and expertise: Described by its vendor as designed by patent experts for patent experts. Professional searchers will use the command syntax and truncations, while the AI features lower the entry barrier.	Typical user and expertise: Questel positions the platform for patentability, freedom-to-operate and invalidity searches by IP professionals.
Cost model and access: Searching is free of charge, and free registration unlocks alerts and PDF downloads for the word-searchable US documents.	Cost model and access: A licensed, restricted-access resource that is often available through university libraries, sometimes with a single-user license. Check with Clarivate for a quote.	Cost model and access: A subscription product with a login. Demonstrations and training are offered by the vendor, and no public price list was found.	Cost model and access: A commercial software platform sold by Questel. The product page shows no prices, so a quote is needed.
When to choose it: Choose it for a quick, no-cost look at US, EP, WO and JP documents, or to download PDFs. For an opinion on infringement or novelty, add a commercial or official source.	When to choose it: Choose it when expert-written abstracts, broad family data and exportable analysis are needed for a decision with commercial stakes.	When to choose it: Choose it when multilingual full-text searching and AI-assisted screening matter and you want integrated analytics in one tool.	When to choose it: Choose it when your searches involve chemical structures or sequences, or you need legal status and prosecution statistics in the same environment.
