RE: Patent term and expiry

You can search the US Federal Register to see the length of Patent Term
Restoration that was granted or is being sought.

Select all of the available volumes and enter the Trade name of the product
in the search box. Remember that PTR takes a while to be granted and show
up in the Orange Book.

Dear Friends,

I shall be thankful to know how the life of a patent
is calculated.The term of a patent shall be calculated
from the date of filing, and normally it shall be 20
years, but If I check with Orange book patent expiry
list, in some cases it is going beyond 20 years.
Kindly enlighten me.

In the United States it is 20 years from date of filing, BUT it can be
extended to the degree that there were delays in the patent office and by
intervention of Congress.
