An oven is an electric appliance used to bake food or make some snacks. General household ovens are more common. Household ovens play an important role in food production, especially in winter, and eating hot snacks is also a kind of enjoyment. Electric oven is an electric appliance that uses the radiant heat of electric heating elements to bake food. According to the trademark encyclopedia, the trademark of oven belongs to11104-cooking and civil electric heating equipment (excluding kitchen utensils and food processing machinery)-convection oven1104; 1 106- drying, ventilation and air conditioning equipment (including heating and cooling room equipment)-oven ventilator cover1106; 1 107- heating and steam equipment (including industrial furnaces and boilers, excluding locomotive boilers, camel boilers and steam engine boilers)-industrial furnaces 1 107. In addition, the bathroom trademark that we often use in our life also belongs to the category of 1 1, which is consistent with the category of oven trademark. The category of sanitary ware trademark is11109-1sanitary ware (excluding toilet utensils), and this subcategory is almost related to sanitary ware trademark. For trademark transfer and trademark registration, we can know that these two ways are ways to obtain trademarks. At different stages, we should understand some minor problems of trademarks and help ourselves get trademarks better and faster. What are these questions? Whether a trademark can be used without registration is related to whether the trademark is protected by law, and has nothing to do with use. Therefore, even if the trademark is not approved, the trademark can still be used in the market, but in this case, if the trademark is infringed, the trademark user will not be able to reasonably defend his rights. How many trademarks can be used on a commodity? The purpose of using trademarks for commodities is to distinguish the commodities of other enterprises in the market, so it doesn't matter if a commodity uses multiple trademarks. After all, the more trademarks are used, the higher the classification of goods. A series of goods can all use the same main trademark, and then use other trademarks that are closer to the goods. Both TM mark and R mark refer to trademarks, but TM mark refers to unapproved trademarks. Anyone who uses this trademark tells everyone that it is marked on the goods as a trademark and is not protected by law, while the R trademark is a registered trademark. Therefore, TM logo is usually used in a wide range, and the same R logo cannot be marked casually. These are some blind spots that use trademarks or are unclear about trademarks. Effectively confirming trademarks and knowing everything about trademarks will help enterprises to use trademarks better and have a good explanation for different degrees of problems.
