(a)    The Secretary of State shall cancel a registration of a mark if:
        (1)    the registrant asks that it be canceled;
        (2)    the registrant fails to renew it;
        (3)    a court of competent jurisdiction orders that it be canceled on any ground; or
        (4)    a court of competent jurisdiction finds that:
            (i)    the mark is abandoned;
            (ii)    the registrant does not own the mark;
            (iii)    the registration was granted improperly; or
            (iv)    the registration was obtained fraudulently.
    (b)    (1)    Subject to paragraph (2) of this subsection, the Secretary of State shall cancel the registration of a mark if a court of competent jurisdiction finds the mark to be likely to confuse or deceive because it resembles a mark that:
            (i)    was registered by another person in the United States Patent Office before the date the registrant applied for registration under this subtitle; and
            (ii)    is not abandoned.
        (2)    The Secretary of State may not cancel the registration of a mark if the registrant proves that:
            (i)    the registrant holds a concurrent registration of the mark in the United States Patent Office; and
            (ii)    the registration in the United States Patent Office covers an area that includes the State.
