The Stronger Patents Act was recently introduced by Senator Coons, and includes a number of provisions that would curb abuses of Inter Partes Reviews. You can find Senator Coons’ interview on CNBC here:

Check out IAM’s story on LinkedIn’s patent history, repeated on IP Watchdog: http://www.ipwatchdog.com/. The evolution of thinking on patents that occurred at LinkedIn is fairly typical of fast growing, baby behemoth, companies like LinkedIn. That is, while in a company such as LinkedIn can typically fly under the patent radar for some years even as it grows rapidly (i.e., not attract much attention from large patent holders, or even trolls for that matter), once it passes a certain size, it is expected to respect the patent portfolios of other companies with substantial patent positions in the space. This respect is typically paid with royalties if a company has little or no portfolio of its own, and later can be paid at least on part with cross-licensing of its own patents, if it has a solid patent position.
