CAS voegt Filipijnen toe als 60ste octrooiverlenenden instantie
CAS is enhancing its extensive patent coverage by adding patent and patent family information from the Intellectual Property Office of the Philippines (IP Philippines), increasing the number of patent authorities covered to 60.
Robust Asian patent coverage The CAS databases are a rich source of unique, difficult-to-locate Asian patent content provided by patent authorities in Hong Kong, Japan, the People's Republic of China, the Republic of Korea, Singapore, and Taiwan. The addition of information from the Philippines Patent Office further enriches CAS' Asian patent coverage.
Strong coverage of smaller patent authorities Patents emerging from smaller patent authorities are often the source of unique inventions. This information is also largely inaccessible to many patent searchers because few information providers cover smaller patent authorities. With CAS’ broad coverage of 60 worldwide patent authorities—many of them smaller patent offices—you can be sure you will not miss this important, one-of-a-kind information
CAS voegt indicator toe voor "multiple basic patents"
Effective December 20, you will be able to identify the multiple basic records in the CA and CAplus databases that have equivalent chemical indexing.
These duplicate records occur as a result of CAS' efforts to provide maximum coverage of substance information disclosed in patents. On July 1, 2008, CAS began adding as basic patents both Patent Cooperation Treaty (PCT) applications and their original national equivalents (those with the oldest priority from the U.S., Germany, United Kingdom, France, Canada, and/or the EPO). This policy was further expanded to include applications from Japan and Russia on January 1, 2009.
An estimated 13,000 patent records added to the CA/CAplus family of databases since 2008 have equivalent chemical indexing because there is no difference in CAS Registry Numbers indexed in the PCT application(s) and their original national application(s).
To enable you to identify records that contain equivalent chemical indexing, an indicator has been added to the Source (SO) field. The indicator will consist of
- a phrase of searchable text containing the following words: Chemical Indexing Equivalent to
- up to two related document number(s)
- the patent country code for the patent with the equivalent chemical indexing
