Mike, that is the point! I am glad for your post (even though I promised to not be baited to post any more to this thread
)
We are all saying (I think - I don't want to put any words in anyone's mouth) that this is rediculous. Some have offered evidence that common terms cannot be trademarked. Others have offered evidence that a "trade mark" is meant to prevent another company from seeking advantage from another company's advertizing. As you have so astutely stated, there are certain terms so engrained in US terminology, they should not be trademarkable. Channel Locks is one. Kleenex is another. Thermos bottle is another. I still say, the business model determines how well a company does, not whether we use the name some other way. Thermos probably doesn't care if we use that term to refer to all vacuum bottles.
