What are the legal requirements for the validity of an exterior patent?

Appearance patents are an important system for protecting product designs in many countries. Through an Appearance Patent, innovators can protect their product designs from imitation or misappropriation by others. However, the validity period of an appearance patent limits the scope of protection and it is necessary to understand the legal requirements for the validity period of an appearance patent.

Generally speaking, the validity period of appearance patents is 15 years in most countries, but the validity period may be different in some countries. In the United States, the validity period of appearance patents is 15 years, while in Europe, the validity period of appearance patents is 25 years. In addition, some countries allow the holders of appearance patents to apply for renewal after the expiry of the validity period, so as to extend the protection period of the patents.

Apart from the period of validity, the scope of protection of an appearance patent is also an important factor to be considered. Appearance patents usually protect only the appearance design with novelty and originality, but not the functional part of the product. Therefore, when applying for an appearance patent, the applicant needs to clearly define the design of the product to ensure that the patent can be effectively protected.

In addition, the scope of protection of appearance patents is also subject to territorial limitations. Even if an appearance patent is granted, its scope of protection is limited to the scope of the country or region. Therefore, if an enterprise wishes to sell its products in several countries or regions, it needs to apply for an appearance patent in the corresponding country or region.

Finally, after the expiration of the term of protection of the appearance patent, the design of the product will enter the public domain, and other people can use the design freely. Therefore, the innovation and protection of appearance design by enterprises is a continuous process that requires constant updating and maintenance.

In conclusion, understanding the legal requirements for the validity of design patents is crucial for enterprises to protect their product designs. By complying with the corresponding legal requirements, enterprises can ensure that their designs are effectively protected under the legal framework, thereby safeguarding their own innovations and competitive advantages in the market.
