Here is what the LAW says
Seems like it just may apply here.

§14 (15 U.S.C. §1064). Cancellation
(3) At any time if the registered mark becomes the generic name for the goods or services, or a portion thereof, for which it is registered, or is functional, or has been abandoned, or its registration was obtained fraudulently or contrary to the provisions of section 4 or of subsection (a), (b), or (c) of section 2 for a registration under this Act, or contrary to similar prohibitory provisions of such said prior Acts for a registration under such Acts, or if the registered mark is being used by, or with the permission of, the registrant so as to misrepresent the source of the goods or services on or in connection with which the mark is used. If the registered mark becomes the generic name for less than all of the goods or services for which it is registered, a petition to cancel the registration for only those goods or services may be filed. A registered mark shall not be deemed to be the generic name of goods or services solely because such mark is also used as a name of or to identify a unique product or service. The primary significance of the registered mark to the relevant public rather than purchaser motivation shall be the test for determining whether the registered mark has become the generic name of goods or services on or in connection with which it has been used.
(5) At any time in the case of a certification mark on the ground that the registrant (A) does not control, or is not able legitimately to exercise control over, the use of such mark, or (B) engages in the production or marketing of any goods or services to which the certification mark is applied, or (C) permits the use of the certification mark for purposes other than to certify, or (D) discriminately refuses to certify or to continue to certify the goods or services of any person who maintains the standards or conditions which such mark certifies:

Abandonment of mark. A mark shall be deemed to be “abandoned” if either of the following occurs:
(1) When its use has been discontinued with intent not to resume such use. Intent not to resume may be inferred from circumstances. Nonuse for 3 consecutive years shall be prima facie evidence of abandonment. “Use” of a mark means the bona fide use of such mark made in the ordinary course of trade, and not made merely to reserve a right in a mark.
(2) When any course of conduct of the owner, including acts of omission as well as commission, causes the mark to become the generic name for the goods or services on or in connection with which it is used or otherwise to lose its significance as a mark. Purchaser motivation shall not be a test for determining abandonment under this paragraph.
