The following three lists of generic and genericized trademarks are:
- marks which were originally legally protected trademarks, but have been genericized and have lost their legal status due to becoming generic terms,
- marks which have been abandoned and are now generic terms
- marks which are still legally protected as trademarks, at least in some jurisdictions
Scientific names should not be allowed to be trademarked. That should include names that are close enough to it that it could be litigated if it were a trade mark.
