iPhone 4S advert (Siri 001)

A week ago, news broke that Apple mulled adding Samsung’s latest Galaxy S4 flagship smartphone to its patent infringement case against Samsung Electronics. It’s not terribly surprising then that Apple has now filed a motion asserting that both the Internet giant’s head-turning Google Now feature and Samsung’s Galaxy S4 handset violate its two Siri patents and five other inventions…

Patent expert Florian Müeller specified on his FOSS Patents blog the five patents Apple is asserting against Samsung – including U.S. Patent No. 5,666,502, U.S. Patent No. 5,946,647 and U.S. Patent No. 7,761,414 – and another two Siri-related patents – U.S. Patent No. 8,086,604 and U.S. Patent No. 6,847,959 – used against the Google Now service.

In its original infringement contentions Apple asserted the ‘604 and ‘509 unified search patents against the Android Quick Search Box. Meanwhile Google has launched Google Now, and Apple wishes to update its infringement contentions accordingly.

Here’s Apple’s filing, embedded as a Scribd document.

13-05-21 Apple Motion to Amend Infringement Contentions

Apple previously claimed Samsung’s Galaxy devices infringe its Siri patents and Judge Lucy Koh back in March greenlit the Siri lawsuit, which involves different patents than the case that went to trial in California last year.

After removing one of the 22 infringing devices and adding the Galaxy S4 added to its second California suit against Samsung, the two parties are expected to duke it out in the courtroom in spring 2014.
