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
That’s what happens when you get a trademark approved that matches the scientific name for the hormone. It should be genericized.
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.
Actually, someone synthesized something very similar in 1897 and named it “epinephrine”. 4 years later, someone independently synthesized it and trademarked it as “adrenaline”.
Seems like a couple people were working on this around the same time.
