There's quite a bit in the press these days about companies (surprisingly, some very large ones) aggressively investing to expand their IP portfolios by purchasing patents or filing for patents on anything that can be imagined - often without stopping to consider whether the "innovation" has utility and is truly novel and non-obvious. Sun is often approached by companies looking to purchase patents (a reflection of the value of our IP) and at times we do sell patents under the right terms, conditions and circumstances.
