The computer chip designer Rambus Inc. announced last week that it’s wrested a $240 million settlement from rival SK Hynix Inc. The deal most likely leaves both sides a bit dissatisfied, but at least they can turn the page on a bruising court fight that’s generated fees for several Am Law 200 firms.

Rambus designed computer chips during the 1990s but never sold its own products. It turned to patent litigation around the year 2000, after its technology failed to gain wide acceptance in the semiconductor industry.
