Re: That's not what "anti-competitive" means

Let's say Sigma creates a protocol that works exactly like Canon's RF protocol, which they call "SPC," and upon examination doesn't use any of the code of Canon's RF protocol.

Doesn't use any code of Canon only means they does not infringe Canon's copyrights.

They may still be infringing their patents.

For copyrights, so long as you are not copying, you are not infringing.

For patents, even if you did not copy, if your method/hardware was the same as described in the patent, you are still infringing.

Patent is not forever though, 20 years after the filing date of a patent, everybody are allowed to copy without paying a penny

If Canon ever find out they are not competitive without third parties support. They can choose to license it to selected parties. These parties usually either need to pay royalties to Canon or exchange usage of their own patents with Canon or both.

Canon may also choose to license their patents after 2030 - not many years left before everybody copy - to get the most out of it.
