We've been buying trademarked, branded stock from our European distributor for years. We have been informed that someone would like to buy the UK trademark for this product. Our supplier is eager to sell and unfortunately, we cannot afford to purchase the trademark, despite being offered to place a bid. We have quite a large amount of existing stock. Could any new trademark owner prevent us selling our remaining stock online generally? Could they prevent us selling on eBay and Amazon? Any help would be much appreciated.
