i am using derwent innovation for searching patent records for various types of searching like patentability, fto etc. The best feature is smart search of the database, it extracts relevant patents automatically only on the basis of terms entered. Review collected by and hosted on G2.com.

Although the database is very fantastic but the user interface to analyze the patents is not good enough, we can not highlight words of our choice and full figures are not visible directly, we need to open the patent to see all the figures. Review collected by and hosted on G2.com.
