How Many Patents Does It Take To Make A Drug - Follow-On Pharmaceutical Patents And University Licensing, Lisa Larrimore Ouellette

I argue that the nature and degree of royal supervision of theatre companies and performance during the period presented no occasion (and, indeed, left no opportunity) for such a right to arise. I discuss the impetus for Parliament's enactment of a performance right statute in 1833, …
