Jane Park is announcing the first in a series of “advanced topics” relating to Creative Commons. The document explains the relationship between rights, trademark and OER. From the post:

For OER organizations with a strong trademark, or with the plans and capacity to build and sustain one, this primer is a guide to understanding the relationship between your organization’s rights as a copyright owner using CC licenses (particularly CC BY) and your organization’s trademark rights within the context of open educational resources (OER). This primer is not relevant for OER creators generally, as trademark law only pertains to those entities with the capacity to build and sustain a brand.
