What is trademark registration? In our country, registered trademarks must be registered by category. Registration of a mark in a broad class counts as a trademark. If the same mark is registered in 45 categories, it will be counted as 45 trademarks. What are the benefits of registering trademarks in all 45 categories? 1. After you register it yourself, it will be more difficult for anyone else to register the same or similar trademark in any major category. This will cause many people to give up applying for registration of identical or similar trademarks in this category. If you have not registered in the 45 major categories, after you have gained a certain reputation, others may register the same or similar trademarks in certain categories. 2. Once the registration is successful, if others use it without consent, you can ask others to stop using it to prevent your trademark from being diluted. 3. If others take a fancy to a trademark in a certain category, they may spend a lot of money to buy it and earn a fee for themselves. What are the disadvantages of registering trademarks in all 45 categories? 1. Registration costs are high. Trademarks are charged per trademark. The cost of registering 45 trademarks is much higher than the cost of registering several trademarks. It costs about 1,800 yuan each to register a trademark with an agency, and 1,000 yuan each directly to the Trademark Office. During the registration process, you may encounter things such as rejection review, objection defense, objection review, withdrawal, third withdrawal review, dispute, dispute defense, etc., which consumes both manpower and material resources. 2. The cost of trademark maintenance is high. Once the business address or name changes, all trademarks under the name must be changed. Changes cost money, and it costs an agency about 800 yuan to change each trademark. Go directly to the Trademark Office to change each trademark for 500 yuan. Managing trademarks in an enterprise also requires labor. 3. Once a trademark needs to be transferred, and if it needs to be transferred, the cost will be high. The agency will charge about 1,800 yuan for each trademark. Go directly to the Trademark Office to apply for 1,000 yuan each. 4. When registering 45 major categories, there will inevitably be situations where some trademarks are not used. If someone else uses your trademark without your consent, and you do not use the trademark, you can only ask others to stop using it and stop infringement, but you cannot ask the other party to pay compensation for infringement. Therefore, it is not completely preventable from being used by others. 5. If someone else wants to register an identical or similar trademark in a certain category, they may request to cancel it and not use it for three years. If the trademark has indeed not been used for three consecutive years, it is still very likely that the trademark will be revoked and someone else will successfully register it. Therefore, it does not completely prevent others from successfully registering. 6. Others take a fancy to a certain type of trademark and spend money to buy it. It is a rare thing. 7. If your trademark is not a made-up word, then even if you register the trademark for all categories, it is very likely that others will not have an adverse impact on you if others use the same trademark on products that are not similar to your core products. For example: Great Wall Wine, Great Wall Computer, Great Wall Lubricant, Great Wall Motors, Great Wall Broadband, Great Wall Fund, etc. It seems that there is no adverse impact on each other at present, and two of them are well-known trademarks. In short, the cost-effectiveness of registering a full class of trademarks is low, the cost is too high, and the income is too low. Under what circumstances is it necessary to register a full class of trademarks? 1. The trademark is a made-up word with strong distinctiveness. If the trademark is merely a highly distinctive, self-created artistic work, it can be protected through copyright. 2. Have sufficient financial strength and do not pay special attention to cost when it comes to trademarks. Pay special attention to income.
