Apple I thought OSNews would be a good forum to talk about a matter that has been weighing on my mind lately primarily because the site has been so focused on Apple's patents and litigation as of late. The news that HP, the largest PC manufacturer in the world is spinning off or getting out of this business is what really prompted me to write this article.

Yes, BIOS was not opened by IBM. But they did nothing when Compaq reverse engineered it. IBM let the PC platform be *cloned*. The let it become the open platform.
While Compaq technically allowed 100% IBM compatibles clones, IBM legally allowed it by doing nothing against it.

IBM didn't have any recourse. The reverse engineered BIOS was a clean room design. One engineer in one room read the specifications of the IBM BIOS to an engineering in a second room who was coding the Compaq BIOS.

That is perfectly legal, and there is nothing IBM could have done after the fact. IBM wasn't being magnanimous; their hands were tied. If there were software patents back then, IBM probably would have sued Compaq.
