Chemical innovation index

The pipeline of innovation, expressed in filed patents, has also changed. The Derwent World Patent Index shows that the number of patents in the world nearly tripled to 710,000/year between 1980 and 2004, whereas in the chemical industry it only doubled to 213,000/year. Since 1992, the number of patents in the chemical industry has been steady.

Science Citation Index , ISI ProceedingsSM, Reaction Citation Index, and the Derwent Innovations IndexSM. Science Citation Index is available on STN , where it is called SciSearch. We wiU begin with the older print-versions for chemical searches. 

Antidepressant drugs A major class of psychotropic drugs with diverse chemical configurations including the monoamine oxidase inhibitors (MAOIs), the heterocyclic drugs (composed of mono-, di-, tri-, and hetero-cyclics), the serotonin reuptake inhibitors (fluoxetine, paroxetine, sertraline, trazodone, and venlafaxine), and bupropion are more recent innovations. Antidepressants usually must be taken for several weeks to have the desired effect and they often have a low therapeutic index, so they must be closely monitored. 

Section 7.4 will discuss the World Patents Index file, the world s largest patent file with intellectual abstracts. The World Patents Index does not specialize in chemistry, but still it is essential for chemical online queries. In order to provide a combined search in CA and the World Patents Index, STN has introduced certain changes and innovations to its command language.
