Principles cannot be property. An identification of "what is" or "what should be", once it has been shared with another person, is "free for all." The formulation of a number of identifications into a system of ideas is the intellectual property of the person who does the formulating.

Objectivism as formulated in Galt's Speech (in For the New Intellectual, the speech is introduced with the words "This is Objectivism") is Rand's intellectual property.

Objectivism as formulated by Nathaniel Branden in his 1960s lectures, and later revised in The Vision of Ayn Rand (2010), is his intellectual property, not Rand's -- although she did endorse it prior to their parting of ways in 1968.

Objectivism as formulated by Leonard Peikoff in his 1976 lectures, and later revised in Objectivism: the Philosophy of Ayn Rand (1991) is his intellectual property, not Rand's -- although she did endorse it in 1976 as the official and best-to-date formulation of her philosophy.

Some day, I will take a crack at formulating a systematic presentation of Objectivism as I think it logically hangs together -- correcting what I think are errors by Rand, Branden, Peikoff et al, and adding identifications of my own -- and that will be my intellectual property, not Rand's.

As long as the West Coast Church of Objectivism confines its comments to those of the philosophical equivalent of Underwriter's Laboratory and says merely "we reject Mr. Bissell's claim to have formulated a true, accurate, and intellectually reliable version of the Philosophy of Objectivism" and do not further try to legally prevent me from publishing it, that will be just fine.
