Apple, Samsung, HTC patent cases slog on

The past two weeks have not been kind to Samsung. On Tuesday, U.S. District Court judge Lucy Koh denied the company’s request to lift an injunction against its 10-inch Galaxy tablet.

Koh, a judge in the U.S. District Court for the Northern District of California, ruled last week that the design of the Galaxy Tab 10.1 infringed on Apple’s design patents for the iPad and issued a preliminary injunction against the device. On Tuesday, FOSS Patents blogger Florian Mueller reported that Koh denied Samsung’s appeal of the injunction which bans further imports of the device.

Samsung is still waiting to hear what Koh has to say about its appeal of a separate injunction against its Galaxy Nexus, which Koh ruled Friday violates an Apple patent on unified search.

It hasn’t all been good news for Apple on the intellectual property front, however. While the company won the rulings against Samsung, it was not as successful with its International Trade Commission request for an emergency ban on all HTC phones, Bloomberg reported.

On Monday, the ITC ruled that Apple hadn’t presented enough evidence that HTC was continuing to infringe on an Apple patent on technology that allows users to dial a phone number by tapping on it in an e-mail. The ITC told HTC it had to stop offering that functionality in its phones in a ruling last December.

In a complaint last month, Apple told the commission that HTC phones, including the One X and the EVO 4G LTE, continued to infringe on that patent .

To date, Mueller noted in another blog post, courts and the ITC have found Android devices infringe on 11 Apple and Microsoft patents, even after the company’s $12.5 billion acquisition of Motorola Mobility and its impressive patent portfolio.

“While patent litigation is a ‘you win some, you lose some’ kind of game, there can be no doubt that Google and its partners are losing this one on the bottom line,” Mueller wrote.
