A simple "U" shaped padlock shackle inspired me to invent other use applications allowing vertical up and down orientation of padlock using a wider and stronger hasp. Easily secures a laptop computer, cell phone, tablet or other electronic like or not devices providing a thicker and stronger padlock hasp.

Mon, 13 Dec 2010   Oh my god!!!  This lock is the BEST!!!  You should market it. 
Thank you so much!  Can I get another one?  Maybe 2 more?  I'll pay for them this time!  Such a smart design.  I'm impressed.
Sat, 14 Nov 2009 Dear Padlock inventor, I too have recently looked at the padlock patents and it is indeed pathetic what the conventional companies continue to sell.
Tue, 02 Sep 2008 I have to admit that those shackles certainly seem very similar to me, but the threshold of "novelty" for design patents is pretty low. There's no functional difference between a lock with a round shackle and one with an octagonal cross-section - but functional difference is exactly what design patents are NOT intended to protect. Clearly, a round shackle is different visually from one with eight sides, and perhaps that's a difference which means something to a padlock manufacturer. Or, more likely, they hope that it will distinguish their goods from their competitors', so that a consumer will see a lock with an eight-sided shackle hanging on a rack with all the round-shackled locks and say, "I like that company's locks, so I'll buy that one." It's not unlike the differences in design of keys for locks - the punched rectangular top doesn't work any better than a round one, but it makes it instantly recognizable as a Kwikset. (Design patent and trade dress/product configuration protection kind of overlap, here) Design patents have their place in the general scheme of protection, but there's a reason why they're less expensive, shorter lived, and easier to get. They just cover a visual difference from what was done before, and for some people, that's enough.
