Patents and other Cans of Worms

I stirred a bit of a hornets' nest in my recent post where I demoed some musical shakers I'd knocked together with my kids. They were inspired by the idea of the Rhythm Ring (Trademark) only we made them out of household items that we had laying around our home. It was all meant to be a bit of fun, but since making that post I've had some pretty horrible messages from someone claiming to be part of the Rhythm Ring company. For the record, I won't be mass-producing the shakers shown in my videos. In fact, the shakers are no more! So that's the end of that!

and Method of Conducting an Exercise Program"

If I've learnt anything from this whole experience it is the wonder that is the Google Patent search. Who'd have thought that there are so many patents filed! I love the ideas - there's some real crazy stuff - but I'm also taken with the pictures and the language of the patents. Here's a run down of some of the shaker-related patents and a few others that stand out for different reasons.

Expect a post soon on Ukulele patents!

  2. Ha ha... Yeah - then they'd know Lizzie! She could do some Brazilian Jiu Jitsu on them! Thanks for commenting. You don't happen to know any electric ukers in your neck of the woods do you?
