from the patent-exhaustion dept
- 7,517,222: Magnetic connector for electronic device
- 7,627,343 & 7,751,853 (really the same patent, as one is a continuation of the other: Female receptacle data pin connector
- 7,783,070: Cable adapter for a media player system
However, where this gets interesting is that, according to Sanho's website, it doesn't make its own magnetic connectors, but simply recycles official Apple connectors:
"Our charging cables use original Apple MagSafe connectors for maximum compatibility,"If that's the case, it seems to raise some questions about patent exhaustion, where a company can't license a patent for one player in a supply chain, but then claim that later buyers, who are buying from the original licensee need to re-license the patent. Think of it as being similar to the principle of "first sale" in copyright. I would think that, on those connectors at the very least, Sanho could make a case for patent exhaustion if it really is just buying up official Apple MagSafe connectors and repurposing them.
