As far as I know, patents were meant to encourage innovation, but lately they are being used as a weapon.
Google has gained hundreds of patents from IBM as it continues its intellectual property spending spree. It has acquired 188 patents and 29 applications, adding to the 1,000 it purchased from IBM last summer.
The spokesman of Google expressed that acquisition those patents can enhance its patent portfolio and increase its competition in the market, even Android would not been threatened by anti-competitive of Microsoft, Apple and other companies easily.
If you desire your innovation to become stronger, prepare more weapons for it now!!
