Nokia threatens to elbow Apple's rival nano-SIM off a cliff

Finns refuse to license vital patents in mobe tiff


Nokia will refuse to license its SIM patents if telecoms body ETSI approves Apple's alternative tiny design, upping the stakes in the battle for the next-generation itty-bitty SIM.

Nokia believes that the adoption of Apple's nano-SIM would contravene ETSI's own rules on a tiny SIM design, thus absolving the Finnish mobe maker of its obligations to fairly and squarely license standards-related patents to Apple. Nokia holds 50 patent families relating to the SIM concept.

Withholding access to these vital patents would make it next to impossible to manufacture the nano-SIM, so Nokia is basically saying that its own tiny SIM design is the only one that could ever be built.

Patents embodied in standards are typically bound by Fair, Reasonable And Non-Discriminatory (FRAND) agreements, which require the patent owner to license them without prejudice. Nokia's SIM patents are part of the earlier standards, but if the ETSI design rules are broken by Apple's nano-SIM then Nokia reckons it won't be required to carry over the FRAND arrangements.

The design rules to which Nokia is referring are the ETSI criteria by which the standard tiny SIM will be selected. Those criteria are explicit, and Nokia reckons its tiny SIM design is a closer match on at least two of the four including the most important one: size.

The dimensions, as judged by ETSI, will include the tray (and associated mechanism) inherent in Apple's design, and Nokia reckons that makes theirs smaller.

Next up is consistency of connections (the 8-pad connection your correspondent has tattooed on his left hand), but we don't have enough information to compare the designs on that score. Third is time to market, which is open to debate, and last comes prevention from wrongful insertion - something Nokia claims will plague Apple's proposal, which is as wide as an existing micro-SIM is long.

It's worth noting that while the physical size and shape of the SIM might not be well covered by patents, the communications protocol and operational architecture is, and it's very likely that Nokia holds essential patents in that area. Working around those patents would mean redesigning the very basis of the SIM, lengthening the time to market and increasing the development cost hugely, if it even proved possible.

With the ETSI criteria being so open it should be a straightforward process to look at both designs and decide which is the closer match, regardless of threats or lobbying, but the very fact that Nokia feels it necessary to make such a threat shows the decision is far from a forgone conclusion.

Apple's proposal is backed by a handful of network operators, named on the submission to ETSI, while Nokia has the backing of RIM and Motorola, but this should not be a political decision even if patent politics has become endemic within the industry. ®

    Fine-print crucially deemed contractual agreement as well as copyright license in smartTV source-code case

    The Software Freedom Conservancy (SFC) has won a significant legal victory in its ongoing effort to force Vizio to publish the source code of its SmartCast TV software, which is said to contain GPLv2 and LGPLv2.1 copyleft-licensed components.

    SFC sued Vizio, claiming it was in breach of contract by failing to obey the terms of the GPLv2 and LGPLv2.1 licenses that require source code to be made public when certain conditions are met, and sought declaratory relief on behalf of Vizio TV owners. SFC wanted its breach-of-contract arguments to be heard by the Orange County Superior Court in California, though Vizio kicked the matter up to the district court level in central California where it hoped to avoid the contract issue and defend its corner using just federal copyright law.

    On Friday, Federal District Judge Josephine Staton sided with SFC and granted its motion to send its lawsuit back to superior court. To do so, Judge Staton had to decide whether or not the federal Copyright Act preempted the SFC's breach-of-contract allegations; in the end, she decided it didn't.

  • US brings first-of-its-kind criminal charges of Bitcoin-based sanctions-busting
    Citizen allegedly moved $10m-plus in BTC into banned nation

    US prosecutors have accused an American citizen of illegally funneling more than $10 million in Bitcoin into an economically sanctioned country.

    It's said the resulting criminal charges of sanctions busting through the use of cryptocurrency are the first of their kind to be brought in the US.

    Under the United States' International Emergency Economic Powers Act (IEEA), it is illegal for a citizen or institution within the US to transfer funds, directly or indirectly, to a sanctioned country, such as Iran, Cuba, North Korea, or Russia. If there is evidence the IEEA was willfully violated, a criminal case should follow. If an individual or financial exchange was unwittingly involved in evading sanctions, they may be subject to civil action.

  • Meta hires network chip guru from Intel: What does this mean for future silicon?
    Why be a customer when you can develop your own custom semiconductors

    Analysis Here's something that should raise eyebrows in the datacenter world: Facebook parent company Meta has hired a veteran networking chip engineer from Intel to lead silicon design efforts in the internet giant's infrastructure hardware engineering group.

    Jon Dama started as director of silicon in May for Meta's infrastructure hardware group, a role that has him "responsible for several design teams innovating the datacenter for scale," according to his LinkedIn profile. In a blurb, Dama indicated that a team is already in place at Meta, and he hopes to "scale the next several doublings of data processing" with them.

    Though we couldn't confirm it, we think it's likely that Dama is reporting to Alexis Bjorlin, Meta's vice president of infrastructure hardware who previously worked with Dama when she was general manager of Intel's Connectivity group before serving a two-year stint at Broadcom.
