It's so cool that it's an inverse delta! Sadly this is probably because they had to find a way to circumvent patents.

- JoeAltmaier 12y agoIts open-source. Maybe patents don't apply? They're not selling anything.
- gnopgnip 12y agoPatents still apply to open source, even if they are not selling anything.
- inputdev 12y agoHow does that work? Genuinely curious - can a patent holder force someone to un-publish source code?
- Someone 12y agoA court can order someone to stop publishing source code and to pay damages for illegally distributed material. In the related field of copyright, courts have been known to order the destruction of books, fake watches, etc.
- exhilaration 12y agoThat's pretty much what happened when a Dutch developer tried to publish source code emulating what the Shazam song-recognition app did: https://www.techdirt.com/articles/20100708/04230710128.shtml https://www.techdirt.com/articles/20100708/04230710128.shtml
- merrillii 12y agoIn the USA if you knowingly violate a patent you will be responsible for triple damages. For software that would be 3X the revenue generated. This is true even if the violator does not charge - because the person with the patent is still suffering damages (lost revenue). So practically they can force you to remove it if they can show damages - which wouldn't be that hard to show in the Shazam example.

- cwkoss 12y agoI think individuals can create projects for personal use which use a patent so long as its only for personal use and is not used commercially or sold.
- lambdapower 12y agoFalse. This is a common misconception. There is also no "academic exemption" to patent infringement.
- mrec 12y agoI agree that GP is dangerously wrong about noncommercial use in general, but doesn't the research exemption[1] muddy the waters a little? [1] http://en.wikipedia.org/wiki/Research_exemption http://en.wikipedia.org/wiki/Research_exemption
- DannyBee 12y agoNo. It is very very limited.
- JoeAltmaier 12y ago"Patents do not prevent "making". They prevent making for another's use. One can make and use anything (well, anything legal, I'm not talking about devices which are themselves illegal)." - Mike McCarty Patents are for commercial use. This is just publishing the details of construction - anybody can make and use such a device for their personal use, despite any patents that exist.
- merrillii 12y agoThat is true in the USA. In the UK, for example, there is an academic exemption. Practically there would be very little damages that could be shown by infringing a patent once in a lab.
- maratd 12y agoWait wait, what? When you file for a patent, you make your invention known. In detail. With plans. That's public. The idea being that if somebody uses your designs, they pay you a reasonable licensing fee. These are just plans. Even if they incorporate patented designs, those designs are public knowledge. It's the use and implementation of those designs that's restricted. Am I missing something?
- TylerE 12y agoYes. Anyone building or using one of these would be open to a patent suit (if it violates any patents). There is no patent equivilant to "fair use".
- pbhjpbhj 12y ago>Anyone building // In the UKPA Section 60(5)(a), (b) says: An act which, apart from this subsection, would constitute an infringement of a patent for an invention shall not do so if - (a) it is done privately and for purposes which are not commercial; (b) it is done for experimental purposes relating to the subject-matter of the invention; ... There are other clauses too, for example allowing farmers to use the products of plants they've acquired lawfully. 35 USC 271 has some very limited exceptions too (research related to pharmaceuticals is one IIRC). It's funny that in the US there is such liberty for copyright but patents seem to be locked down relative to other jurisdictions. I assume you're talking about USA, no one ever seems to note despite it being crucial in discussions of law.
- samatman 12y agoNot necessarily. Tilting the substrate platform lets you build more complex shapes without support material.
- jeffchuber 12y agoI have a delta 3d printer and I'm having a hard time imagining how this would work... Do you have an example?
- samatman 12y agoLooking closer, this doesn't apply here. The Stewart platform allows 6 degrees of freedom, with useful amounts of tilt. The inverted delta used here is 3 axis.
