A Purse Lock Patent

My friend Ralph has two patents, the first being 8,935,202 granted January 13, 2015 and filed way back in June 2004. In the early days of google patents, Ralph checked to see if his patent had been granted. It hadn’t been when he checked but he did find something astonishing. It turned out that his great-great-grandfather had been issued patent 306,898 for a purse lock in 1884 . Neither Ralph nor his father knew about it. Apparently it was granted shortly after his great-great-grandfather had emigrated to the US from wherever Brendlers hail from. It’s unlikely that Ralph would have ever found this patent had it not been for google patents.

Ralph’s more recent patent is 10,796,235. Both of his patents are computer related and aren’t nearly as fun as patenting a purse lock.

Canadian cpcs

I’m a member of piug (Patent Information Users Group) and one day someone asked about cpcs. Not the new classification system (Cooperative Patent Classification) but the obsolete one (Canadian Patent Classification) phased out in 1989. Someone from the Canadian Patent Office replied with a pdf of the classifications! It was pointed out that it is quite similar to the uspto’s USPC (United States Patent Classification. It is just me, or have others noticed that the acronym’s meanings don’t seem very creative). I had already created a searchable page for USPCs so it wasn’t all that difficult to create one for Canadian CPCs. The really funny part was that the guy from the Canadian Patent Office replied saying that he shared the link to my CPC search with his colleges!

To quote the original poster, “Using the Canadian CPC is the only way to search hundreds of thousands of expired Canadian Patents that are not classified by IPC and are definitely not text searchable.”

The full piug thread is here http://wiki.piug.org/display/PIUG/Canadian+Patent+Classifications and my Canadian CPC pages are listed here https://historicip.com/patent-classification-systems/#CA And yes, I know that saying Canadian CPC is redundant (the first C of CPC = Canadian) but I needed a way to distinguish it from the other CPC and didn’t want to spell out the acronyms each time.

An Interesting Design Patent!

Question: When is a design patent not a design patent?
Answer: When it is a trademark’s registration certificate of course!

Just when I thought I’d seen it all I came across this on uspto.gov:

Design patent D17061’s drawing page is for a dish design but the specification page is actually the registration certificate for trademark 17061. A simple enough mistake right? But here’s the twist, the registration certificate online is almost illegible and is stamped ‘Best Available Copy’ but they’re wrong! The best copy is in D17061 which looks just about perfect!
