Samsung has earned quite a name for itself copying Apple’s most successful products, but it’s not only in smartphones, tablets, computers, and accessories where the South Korean company sources its inspiration from its closest rivals. British manufacturer Dyson is suing Samsung for allegedly ripping off one of its inventions in a new vacuum cleaner that was unveiled at IFA in Berlin last week.

Over the weekend, President Obama weighed in on the famous Apple vs. Samsung patent disputes by vetoing an import ban proposed by the International Trade Commission that would have prevented Apple from bringing iOS devices older than the iPhone 4S and iPad 3 into the country.

An avowed fan of Apple’s products, it was the first time a U.S. presidential administration had vetoed a product ban by the ITC since 1987, and seemed to signal that the Obama Administration was not going to penalize an American company like Apple in favor of a foreign company like Samsung.

Financial Markets took notice. Samsung’s market cap is down a billion dollars since the vetoing.

Apple’s “pinch to zoom” patent, which features prominently in a patent dispute against Samsung, has been dismissed by the U.S. Patent and Trademark Office. According to documents filed by Samsung in a U.S. federal court, all 21 claims of the patent have been rejected in a “final office action.”

Apple and Samsung will meet in the U.S. Court of Appeals for the Federal Circuit court next month as Apple steps up its bid to have a number of Samsung devices banned in the United States.

The Cupertino company is hoping to reverse the court’s decision not to remove then handsets from sale when they were found guilty of infringing Apple patents last August.

Apple has lost its bid to add the new Galaxy S4 to its ongoing patent lawsuit against Samsung. U.S. Magistrate Judge Paul S. Grewal said that adding yet another device to the case is a “tax on the court’s resources,” and that it takes time away from other parties who require the court’s attention.
