What technical patents are involved in a mobile phone?

At present, any mobile phone has at least hundreds of thousands of patents.

1, design.

The appearance of a mobile phone may have many design patents, such as the position and shape of the receiver; The shape of the back; Overall shape and size; Software interface style, etc.

2. materials.

There may be multiple patents on the materials used in mobile phones, such as the patent of the shell material itself, the patent of the manufacturing process of the material, and the patent of the process when the material is made into various parts of the mobile phone.

3. Function.

There may be many patents for various application functions in mobile phones, such as calling, SMS, WeChat, games and so on.

4. components.

Every component in a mobile phone may have multiple patents, such as battery, CPU, memory, camera, various sensors, power interface, USB interface, and the interaction between these components.

5. Internal structure.

There may be many invention patents and utility model patents on the placement of various components in mobile phones, how to make them light and thin, how to dissipate heat, how to wire them, etc.

6. Agreement.

This is the most patented. Take the 4G mobile phone as an example, it needs basic patents such as 4G, 3G and 2G, and each communication protocol has tens of thousands or more patents, otherwise the mobile phone will not be able to realize the communication function. Include bluetooth protocol, wifi protocol, etc. Each protocol also has many patents, and there are various audio and video decoding protocols, such as MP3 and mp4, all of which have protocols, and the number of patents is huge.

The above is only a preliminary list.

It can be seen that the mobile phone is a product with concentrated patent technology in the field of electronic communication and the crystallization of the wisdom of many scientific and technological personnel, and it is very convenient to use. Because of its intensive patents, this is one of the reasons why patent litigation in the field of mobile phones is very frequent.

Basic classification

There are three types of patents in China:

1, invention patent

The definition of invention in the first paragraph of Article 2 of the Detailed Rules for the Implementation of the Patent Law of China is: "Invention refers to a new technical scheme proposed for a product, method or its improvement."

The so-called products refer to all kinds of new products that can be manufactured in industry, including solids, liquids and gases with certain shapes and structures. The so-called method refers to the method of processing raw materials and making various products. Invention patents do not seek technical achievements that can be directly applied to industrial production through practice. It can be a solution to a technical problem or an idea with the possibility of industrial application. However, this technical scheme or idea cannot be confused with simply putting forward a topic or idea, because a simple topic or idea does not have the possibility of industrial application.

2. Patent for utility model

The definition of utility model in the second paragraph of Article 2 of the Detailed Rules for the Implementation of the Patent Law in China is: "Utility model refers to a new technical scheme suitable for practical use for the shape, structure or combination of products." Like the invention, the utility model protects a technical scheme. However, the scope of patent protection for utility model is relatively limited, which only protects new products with a certain shape or structure, and does not protect methods and substances without a fixed shape. The technical scheme of the utility model pays more attention to practicality, and its technical level is lower than that of the invention. Most countries' utility model patents protect relatively simple and improved technological inventions, which can be called "small inventions".

3. Design patents

The third paragraph of Article 2 of the Detailed Rules for the Implementation of the Patent Law of our country defines design as: "Design refers to a new design that is aesthetically pleasing and suitable for industrial application for the shape, pattern or combination of products, as well as colors, shapes and patterns."

Appearance design is obviously different from invention and utility model. Appearance design focuses on the designer's artistic and aesthetic creation of the appearance of a product, but this artistic creation is not a simple handicraft, it must be practical for industrial application.

In essence, design patents protect artistic creativity, while invention patents and utility model patents protect technical creativity; Although the design and utility model are related to the shape of the product, they have different purposes. The former aims to make the appearance of products beautiful, while the latter aims to make products with appearance solve a technical problem. For example, if the shape, pattern and color of an umbrella are quite beautiful, it is necessary to apply for a design patent. If the umbrella handle, umbrella ribs and umbrella head are simple and reasonable in structural design, can save materials and have durable functions, you should apply for a patent for utility model.
