As has been already stated, protocols cannot be patented - only their specific implementations. This has been tested in courts ad nauseum by the computer industry, and it's vanishingly unlikely to change because of RC players and their comparatively miniscule revenue.

Linux can talk SMB (samba). Microsoft had its own IPX/SPX stack back when that protocol suite still mattered. BSD had its own AppleTalk implementation called Netatalk. HH could litigate till they're blue in the face, but they can't legally prevent third parties from developing their own implementations of the DSM2 and DSMX _protocols_, irrespective of whether the protocol specs are published or reverse engineered.

Regardless of if it is possible to patent systems that contain interfaces :
Does anybody know if Horizon has tried to sue Orange earlier for making DSM receivers? Or if Futaba has sued FrSky for making compatible FAAST receivers?

Someone knows what they are talking about! I though we had ended this argument 15 pages ago with the exact same conclusion?

For anyone who needs an example take <a href="http://en.wikipedia.org/wiki/ReactOS">ReactOS</a>, a 100% white-room reverse engineered, feature complete "copy" of Windows XP. Since the developers can and has proven many times that the software was copied but merely a function (read protocol) was implemented, Microsoft cannot do anything to shut the program down.

Now if anyone still wants to argue can you please find examples where a protocol/function has been implemented, and thus gone to court, and the original designer has won. There are 4 case points already against the arguement.

But the question I have is:
Orange are not making copy Spektrum recievers, branded as spektrum, they are making their own receivers that are compatible with DSM protocol.

Isn't it similar to me buying a genuine toyota part for my car, or a 3rd party compatible part from repco? They seem to be legal.

But early editions of the orange receiver had circuit boards that were identical to Spektrum's. Which led to an interesting question. Did they also just copy the firmware (which would be illegal) and put it on their boards? Or did they develop their own DSM2 compatible firmware?

The chipset that Spektrum uses isn't their own; if I recall correctly, it is made by Texas Instruments. The only thing they really have copyrights on is their firmware, and maybe the board layout. If someone wants to use the same TI chips and reverse engineer the over-the-air protocol, and implement it in their own software, all power to them.

Cypress 2.4ghz chipset - same one that the orange RX's use.

Now that they obviously have access to the DSMX protocol, why don't they make the T9XR DSMX compatible like the new Orange Spektrum module, so that they can enter the market with an up-to-date RF system?

Or am I missing something?

Yes, DSM2/DSMX is a feature on the 9XR.

looking interesting. Especially since Spektrum has said time and time again that they can't make a DSM2/DSMX module. Seems Orange has done something with the Spektrum Protocols that Spektrum can't do.

RCmodelreviews.com, I hope you are going to take a look at this.

Spectrum only say that because they want to make money off of JR's and their own upper class TXs. Now that OrangeRX has released the module and the 9XR will have a similar module they will probably rethink their stance so they can still make some money off of DSM2/DSMX.
