1)Patentability SearchTo confirm the patentability of the invention by investigating prior art.
This will reduce useless patent applications.
Purpose of making use of PI data
2)Freedom-to-Operate SearchTo confirm that own products may not infringe patent rights of other
companies. 3)Validity/Invalidity Search
To find prior art that can invalidate a patent when finding a patent that obstructs own business or receiving a warning of patent infringement.
