Actually, the reason why people could come up with clones was that IBM
didn't patent the *BIOS*.

The ISA bus itself is a straightforward 8086 bus. What they could probably
do is put a trademark on the arrangement of the ISA bus lines preventing
other people from creating PCs using this very pinout, but they can't
keep 3rd party vendors from building ISA peripherals.
