It's essential that the US patent system is adjusted. There is a large and growing business (it perhaps should be called an industry) that buys flimsy patents and then makes laughable claims of infringement by legitimate businesses.

The costs associated with fighting these claims are so high that many companies settle for less than the costs associated with the fight.

The whole system is a sham and a very real break on the competitiveness of the US; it also confuses the situation for "proper" patent-holders. Let's hope Washington can think for themselves for once and not get swayed by silver-tongued lobbying scoundrels.
