A trademark does not protect the item's design or engineering, thats what a patent does.
From a legal dictionary:
A TRADEMARK is a word, a name, a symbol, a device, or a combination of them that indicates the source of goods or services. Distinguishes the products or services of one business from those of others in the same field. The owner/assignee/licensee of a trademark/mark has the right to exclude others from using that trademark/mark by being the first to use it in the marketplace. Rights in a trademark/mark are obtained only through commercial use of the mark. The owner of a trademark/mark has the right to exclude others unless the trademark/mark has been abandoned. Secondly, that although any other person may manufacture, produce, and sell any such article, yet he must not, in manner, either by using the same or similar marks, wrappers, labels, or devices, or colorable imitations thereof, or otherwise, hold out to the public that he is manufacturing, producing, or selling the identical article, prepared, manufactured, produced, or sold by the other; that is to say, he may not make use of the name or reputation of the other in order to sell his own preparation.
PATENT - A legal document issued by the United States to the inventor. The inventor, as the owner of the patent, has the right to exclude any other person from making, using, or selling the invention covered by the patent anywhere in the United States for 17 years from the date the patent was issued; A document issued to an inventor by the U.S. Patent and Trademark Office. Contains a detailed description of what the invention is and how to make or use it and provides rights against infringors. (note: due to factors including the Gatt treaty the time period for patents is undergoing changes. 5/95)
All this is to indicated that the current Douglas should not be a problem with Rondo because it has been longer than 17 years since the MM Stingray was introduced and the current seller is not using the MM name.
Ok so the Douglas bass is legal then, correct?
