Individuals are "persons" in law unless they are minors or under some kind of other incapacity such as a court finding of mental incapacity.
Many laws give certain powers to "persons" which, in almost all instances, includes business organizations that have been formally registered such as partnerships, corporations or associations.
For example, the US Code defines "person" as follows (at Title 1, Chapter 1, ¶1):
"The words person ... include(s) corporations, companies, associations, firms, partnerships, societies, and joint stock companies, as well as individuals."
