There are several different kinds of patents that satisfy different purposes.
Utility Patents (aka Nonprovisional Patents)
In very general terms, these patents protect what an invention does or how it is made. Typical Chemical, Mechanical, or Electrical inventions fall under this heading.
A Utility patent application is appropriate where the inventor wishes to protect the way the invention is made or how it functions. A Utility (or Nonprovisional) patent application may lead to full patent rights. The current patent term is 20 years from the filing date. A Utility application may “piggyback” from a Provisional application if it is filed within one year of the filing of the Provisional application as described on https://fingerlakes1.com/2021/07/08/team-up-with-inventhelp-to-take-your-career-to-the-next-level/.
A very short-term (1 year) application that is not even examined at the US Patent and Trademark Office. Often very useful before filing a Nonprovisional application.
A Provisional patent application gives the applicant temporary patent pending status. A Utility or Nonprovisional application must be filed within one year of the Provisional application’s filing date to preserve your rights.
Protects the way something looks or other nonfunctional qualities.
Protects certain kinds of cultivated plants.
