Last week, he scooped up Social Gaming Network and Hallpass Media to augment staff and add mobile games to the company’s Web products. (New York Times) Apple filed a patent suit against Samsung, claiming the company’s Galaxy smartphones and tablets infringe on several patents and asking for injunctions, actual damages and punitive damages. “It’s no coincidence that Samsung’s latest products look a lot like the iPhone and iPad, from the shape of the hardware to the user interface and even the packaging,” an Apple rep told All Things D.

(All Things D and AFP) In other Samsung news, the South Korean giant announced a “strategic alignment” worth $1.375 billion with Seagate that will basically expand the two companies’ existing relationship and better position them against competitor Western Digital. As part of the agreement, the two will combine hard drive operations. (TechCrunch) Popular file-syncing start-up Dropbox grew more than 500% in 15 months, from 4 million to 25 million users.
