From which date does a typical utility patent term begin?

• A. 10 years from filing date
• B. 20 years from filing date
• C. 14 years from publication date
• D. 20 years from grant date

Answer: (B)

The main idea is that the protection period for a utility patent is set from the moment the first patent application covering the invention is filed. In common practice, the base term is 20 years from that filing date, not from when the patent is granted or when it’s published. This means the clock starts when you submit the earliest non-provisional filing, and it can be adjusted for delays in the patent office, but the starting point remains the filing date. Starting from the grant date would shorten the protected period, and starting from the publication date or using a different number (like 10 years) doesn’t reflect how patent terms are defined. So the correct starting date is 20 years from the filing date.
