Rambus is still paying for its decision to shred reams of documents before it launched a litigation campaign against a big swath of the semiconductor industry. The latest blow came on Friday, when the judge most sympathetic to Rambus over the years ruled that the company spoliated evidence and signaled that he would reduce a $397 million judgment that Rambus won against rival SK Hynix in 2009.

Rambus is asking the California Court of Appeal to revive its price-fixing case against Micron and SK Hynix, saying that lower courts erred by excluding evidence that its alleged co-conspirators pleaded guilty to federal charges. Rambus also accuses Hynix of improperly striking two of the three African-American members of the jury pool, in part because Rambus' lead trial counsel was African-American.

A U.K. court ordered Apple to run ads stating that Samsung didn't copy the iPad's design; the topic of intellectual property came up in a presidential debate; the inner workings of patent aggregator Intellectual Ventures may get more exposure; and SK Hynix asked for a re-do of a trial that resulted in a huge verdict for Rambus
