A: Plant patents like PP19567 for the Begonia 'Metallic Mist' are indeed limited in time. In the United States, plant patents have a term of 20 years from the date of filing the application.

For this specific patent:

- Filed: October 23, 2007

- Granted: December 9, 2008

- Expiration: October 23, 2027 (20 years from filing date)

After the expiration date, the patent protection ends, and the plant variety enters the public domain. This means that after October 23, 2027, others would be free to propagate, sell, or use this specific Begonia variety without infringing on the patent rights.

It's worth noting that while the patent protection ends, other forms of intellectual property protection might still apply, such as trademarks on the plant's commercial name. However, the specific rights granted by the plant patent will no longer be in effect after the expiration date.
