I have two questions. I have an idea for innovative web browser. The web browser has multiple inventions. I am planning to write two different provisional patents for it to cover the multiple inventions. Is it okay to have some of the features be the same for both provisional patent applications? The feature is innovative (such that it could be independent claim) but it is not the defining invention or features. Second question is I have to define and name a lot of things in the invention. Can I use the some of same terms and definitions for both provisional patent inventions?
