Introduction
Measurement search allows searching for specific measurements units within a patent such as length, temperature, weight and others.

In which patent fields?
Search can be performed in Claims /CLMS and Description /DESC of patents. US examples (/DESX) are also included.
Geographic coverage
Published patents and patent applications for the following collections: US, CN, JP, EP, WO, KR, DE, CA, IN, FR, GB, AU, IL.
Limitations
- English version only (original or machine translation). Original language is not indexed. Non-English original language is not indexed.
- Limited to the family level search (thus FamPat collection)
