Industrial design is the external appearance of a product or part to be assembled into a complex product, expressed by shapes, lines, colors or a combination of these elements and visible during the process of exploiting the uses of the product or complex product.
Products are understood as objects, tools, equipment, and vehicles, produced by industrial or handicraft methods, with clear structures and functions; Parts for assembly into complex products are parts capable of independent circulation and can be disassembled from the complex product; A complex product is a product made up of many replaceable parts that can be removed and reassembled. Products and parts used to assemble and compose complex products below are collectively referred to as products unless otherwise specified.
Conditions for industrial design protection are specified in Articles 65, 66, 67 of the Law on Intellectual Property 2005, amended in 2022; Clause 9 Article 23 Circular 23/2023/TT-BKHCN. Accordingly, industrial designs are protected if:
In case there are many applications for registration of industrial designs that are identical or not significantly different from each other, a protection title will only be granted for the industrial design in a valid application with the earliest priority date or filing date among the applications that meet the conditions for being granted a protection title.
In case there are multiple applications for registration of industrial designs that are identical or not significantly different from each other, meet the same conditions for being granted a protection title and have the same priority date or earliest filing date, a protection title will only be granted to the subject matter of a single application among those applications according to the agreement of all applicants; If no agreement can be reached, the respective subjects of those applications will be denied protection titles.

The validity of industrial design patents begins from the date of issue and lasts until five years from the date of filing. The owner can renew two consecutive times, each for five years. The total period of protection shall not exceed fifteen years.
Renewal needs to be done within six months before the expiration date. Owners need to pay the renewal fee to the Intellectual Property Department. If the grace period expires, the exclusive right ends. The extension must comply with Article 93 of the Law on Intellectual Property. Legal timelines must be guaranteed:
