Intellectual property rights can be divided into copyrights and industrial property rights. Copyright is copyright; invention patents, trademarks and industrial designs constitute industrial property rights, including patents, trademarks, service marks, manufacturer names, names of origin, suppression of unfair competition, new plant variety rights and integrated circuit layouts Design exclusive rights, etc. < /p>

3. IDEA, the objects protected by the Patent Law include inventions, utility models and designs. (Inventions refer to new technical solutions proposed for products, methods or their improvements; utility models Refers to new technical solutions proposed for the shape, structure or combination of products that are suitable for practical use). From the perspective of the difference between patent law and copyright law protection, its essence is to protect ideological content. However, upon closer inspection, "intellectual content" "Rules and methods of activities" belongs to the IDEA category, but does not belong to the subject matter of patent protection. Therefore, from a strict perspective, the answer 3 is incorrect, but from the perspective of the questioner's intention, 3 should be selected.

4. Software, protected by software copyright in my country, is an intellectual property right.

5. Brand refers to the name of a company, the trademark of its products or services, and other trademarks that can distinguish it from the competition. Intangible assets such as competitors' logos and advertisements that constitute a company's unique market image (see /wiki/%E5%93%81%E7%89%8C). There is no doubt that trademarks are objects of intellectual property protection, but company names are generally protected against unfair competition, and other intangible assets are generally protected against unfair competition. Since the concept of brand has a broader meaning than trademark, I personally think , should not be selected, but I am not particularly sure about this.

Hope this helps.
