The geometry of the head can change, and that is patentable. E.g. phillips vs flathead vs Torx, etc.

- bpicolo 9y agoBut wouldn't you need a purpose more substantive than "DRM" for it to be a real patent? Or is it covered under a design patent?
- NikolaNovak 9y agoSorry, can't really answer; I read articles as an interested computer geek, but I'm definitely not an IP lawyer. And most of us tend to make a mess out of patent/copyright/trademark issues when we try to stray outside of our expertise... I tried to disambiguate that lots of people claimed new design was patented; it may however have just been rare / impractical to obtain initially.
- Domenic_S 9y agoThe purpose is generally an improvement -- ease of fastening compared to other heads, faster assembly time, easier to manufacture the heads, etc etc. Check out the history of Robertson and Phillips.
