Name one.
To take some examples I happen to have first-hand intimacy with: Linux is both original and good, but the original parts are frequently not good, and the good parts are clones of Solaris. Touchscreen happened in iOS first. Modern virtualization happened in VMware's closed-source base first. Modern information retrieval is still a proprietary Google secret.
The most important counter-examples I can think of are languages. The "everything is a hash table" descendants of Perl and javascript (in which I include Python, Ruby, and PHP) would not have been viable as commercial products. That said, even javascript began life as a Netscape proprietary implementation, and Perl is mostly a synthesis of ideas present in ksh.
