WTMPD Usage Examples

The database has been used heavily by examiners at SIPO for prior art search.

In 2009, by using our two databases - WTM patent database, TCM compound registry file and Shanghai TCM non-patent literature database , combining modern structure –biology technology and drug design technology, a research group has found a new way to design a new TCM recipe that may prevent and treat H1N1 virus infection.
