What is a Patent?
Patent is a State Grant of property right to the inventor for the purpose of providing
legal protection for an invention. In other words it is a legally enforceable right
granted to the inventor for a limited period of time to exclude others from
making, using, importing, offering for sale, or selling the invention within a particular
jurisdiction wherein the patent rights are granted.
In terms of the Sri Lankan law a patent is protected for 20 years from the date of application. However the owner is required to pay an annual fee to the patent office from the 2nd year of grant to keep the patent live or legally in force. << back
