Originally designed to encourage invention, the patent system has been abused by large companies who build up patent portfolios so that they can use them as a tool to crush smaller competitors.
For a recent example of how IBM attempted to use the patent system to wipe out a technical innovator who dared to break IBM’s monopoly on mainframe systems, see this article from The Register.
After nearly two years of legal wrangling, IBM decided to buy out their upstart rival before the patents could be tested in court. See this follow-up article for details of the ignominious end to the story.
More in-depth coverage of the background behind the case is here.
