The term "HHO" has been trademarked by Headwaters Corporation. It is too late to file for notice of opposition. Two applications were filed, one has since been abandoned, and one is still active. Use of the trademarked term "HHO" on this group to refer to anything other than the trademark holders intended trademark use is a violation of the trademark holders rights, and may result in the removal of offending members. Repeated violation will result in a ban.
