| A couple weeks ago I had the opportunity to talk to OIN's CEO, Jerry
| Rosenthal, who was with IBM for 37 years before setting up OIN. His comments
| about patent trolls – companies whose business is based purely around suing
| others for alleged patent infringement, rather than on making and selling
| things – and how to deal with them, are particularly interesting in the light
| of what has happened since the interview took place. * *
