- FALSE. You can't `copyright' a protocol, only the code used to implement it.
- If someone wrote a BiModem (probably calling it something else, since the name
- might be a registered trademark) by reverse-engineering the BiModem protocol
- standard, then it's perfectly OK. There's plenty of legal precedent to
- support that, software patents notwithstanding. Now, if the guy who wrote
- BiModem for the PC suddenly came up with a patent on the protocol, then you
- might be screwed... but usually only big companies can get away with crap
- like that.
-
- Copyright law doesn't protect ideas or algorithms, only implementations (i.e.,
- the expression of an idea). That's why you can write a spreadsheet that reads
- Lotus 1-2-3 files and get away with it. Good thing most look-and-feel
- copyright lawsuits have failed.
