Expanded access to Taiwanese patent information provided by new full text database TWFULL and claims coverage in CAplus(SM)

Interested in the patents of Taiwan, one of the world’s leading innovators? Building on the coverage of Taiwan already included in various databases within CAS STNext, a new value-added full text patent database, TWFULL, is now available. In addition, CAplus now provides access to Taiwanese claims.

TWFULL provides coverage of patent applications, granted patents, utility models, and design patents, from 1950 to the present.

Value-added features include:

-Numeric property searching of 59 chemical and physical properties. See HELP NPS within TWFULL for details.
- Key Terms to help users determine relevance and expand search scope. These are 1-5 word phrases extracted from English text fields (title, abstract, detailed description, and claims). See HELP KEY for further information.
-The ability to search Independent Claims, either individually (/CLM.IC) or with their dependent claims in claims groups (/CLM.CG).
-A searchable Detailed Description (/DETDEN) field, providing precision searching capabilities.

Coverage of claims data in CAplus was recently expanded to include Taiwan, back to the year 2000. More than 70,000 records now provide claims. For further information, see HELP CLM while in CAplus.
