2. Any registration granted under this chapter or prior law and not renewed in accordance with the provisions hereof; or

The registered mark has been abandoned; b. The registrant is not the owner of the mark; c. The registration was granted as a result of a clerical error; d. The registration was obtained fraudulently; e. The mark is or has become the generic name for the goods or services, or a portion thereof, for which it has been registered; or f. There is a substantial likelihood of confusion with a mark or trade name previously used in this Commonwealth by another and not abandoned.

C. Before the Commission cancels or partially cancels any registration under subdivision A 3, the Commission shall give reasonable notice and an opportunity to be heard to the registrant and to other persons known to have or claim an interest in the mark.
