General Mills Granted A Design Patent On A Tortilla Bowl Because Why Even Pretend Anymore?

Saturday 25th of June 2016 01:49:02 AM
The idea is that the "invention" in the case of design patents are supposed to be unique outputs of what might otherwise not be unique inventions that are then said to act as some sort of single-source invented thing. Honestly, the whole concept smells of a workaround on the actual purpose of patent law and it tends to function that way as well. How else do you explain the design patent granted on a toothpick with some lines carved into it, for instance? Or Apple's design patent on the animation of turning a page within an ebook? Rewarding exclusivity to these types of "inventions" that barely work up the sweat of an "inventor" should seem absurd to you, as should the frequency with which the public is left wondering where exactly the "invention" is in any of this.

Security Leftovers

  • Chrome vulnerability lets attackers steal movies from streaming services
    A significant security vulnerability in Google technology that is supposed to protect videos streamed via Google Chrome has been discovered by researchers from the Ben-Gurion University of the Negev Cyber Security Research Center (CSRC) in collaboration with a security researcher from Telekom Innovation Laboratories in Berlin, Germany.
  • Large botnet of CCTV devices knock the snot out of jewelry website
    Researchers have encountered a denial-of-service botnet that's made up of more than 25,000 Internet-connected closed circuit TV devices. The researchers with Security firm Sucuri came across the malicious network while defending a small brick-and-mortar jewelry shop against a distributed denial-of-service attack. The unnamed site was choking on an assault that delivered almost 35,000 HTTP requests per second, making it unreachable to legitimate users. When Sucuri used a network addressing and routing system known as Anycast to neutralize the attack, the assailants increased the number of HTTP requests to 50,000 per second.
  • Study finds Password Misuse in Hospitals a Steaming Hot Mess
    Hospitals are pretty hygienic places – except when it comes to passwords, it seems. That’s the conclusion of a recent study by researchers at Dartmouth College, the University of Pennsylvania and USC, which found that efforts to circumvent password protections are “endemic” in healthcare environments and mostly go unnoticed by hospital IT staff. The report describes what can only be described as wholesale abandonment of security best practices at hospitals and other clinical environments – with the bad behavior being driven by necessity rather than malice.
  • Why are hackers increasingly targeting the healthcare industry?
    Cyber-attacks in the healthcare environment are on the rise, with recent research suggesting that critical healthcare systems could be vulnerable to attack. In general, the healthcare industry is proving lucrative for cybercriminals because medical data can be used in multiple ways, for example fraud or identify theft. This personal data often contains information regarding a patient’s medical history, which could be used in targeted spear-phishing attacks.
