Manhattan (/mÃ¦nËhÃ¦tÉn/, /mÉn-/) is the most densely populated borough of New York City, its economic and administrative center, and its historical birthplace.[4] It may be known locally as simply The City.[1] The borough is coextensive with New York County, founded on November 1, 1683, as one of the original counties of the U.S. state of New York.
The patent for Lialda currently expires in June 2020. This is the earliest possible date that a generic version of Lialda could become available. However, other circumstances could come up to extend the exclusivity period beyond this time.
US patents with a filing date before June 8, 1995 provide protection for up to seventeen years counting from the date of grant (the date given with reference numeral 45), or 20 years from the filing date, whichever expires later. However, the patent holder is required to pay maintenance fees to keep his patent valid. In most European countries, these fees are yearly. The USA requires maintenance fees to be paid at 3.5 years, 7.5 years, and 11.5 years after issuance. If the holder does not pay a maintenance fee, the patent becomes abandoned.
