[comp.sys.apple2] Knockoffs and Copyrights

ehsu@husc7.HARVARD.EDU (Eric Hsu) (03/11/90)

	I was wondering what the law says about writing and distributing
your own versions of commercial games. For instance, could I write a 
knockoff of Tetris and distribute it as shareware? I know Joe Holt did his
own (incredible) version of Defender, which he made public domain. Didn't
this infringe on someone's copyright?
	To avoid a long legal thread, I ask that responses be e-mailed to me.
If people care, I'll post a summary.
