Glossary
PatentsView also has a very nice glossary that I discovered later.

“Inventor: individual(s) who have contributed to the claimed invention. However, they may or may not have an ownership interest in the legal rights of the patent.”
“Applicant: Organization or individual that files the patent application is called the “applicant.” This could be the original inventor, or it could be the assignee.”
