Back to the Basics Series: Design Patents and Utility Models in China

PatentsChina remains among the top destinations for any business looking to internationalise, and the business environment there is still evolving in terms of both production and consumption. Its growing capacity to produce sophisticated manufactures and complex services is matched by an increasingly affluent domestic consumer base that demands state-of-the-art, internationally popular brands and products.

Although stories of Chinese counterfeits and brand infringements are still regular news in international media, the IPR system in China has seen considerable development in the last decade. This is propelled to a large extent by domestic industries innovating like never before and keen to protect their new technologies, and also those trying their chances with as many IPR filings as possible in order to improve their status or satisfy local government innovation drives. Whatever the reason, the number of patent applications shows the trend clearly: a 20.5% year-on-year increase for 2015 to more than 1,124,000 applications. Also, foreign patent applications are increasing fast, boasting a 14.9% year-on-year increase for 2015.

Although patents are commonly the most complex and time-consuming type of IPR when it comes to registration, China not only offers the more traditional invention patent type, but also design and utility model variants. These additional patent types are a significant plus to businesses looking to protect their intellectual assets, as they typically require a less stringent level of innovation and are granted much faster.

Design Patents

Due to the difference in regional systems, many foreign companies do not know how to protect their product designs in China. For example, while in Europe a business can seek protection for an original work as either a registered or unregistered community design, in China no protection is offered to unregistered designs – they must be registered as patents.

A Chinese design patent provides exclusive use of the aesthetic features of a product for a period of 10 years; that is, protection of the way a product looks as opposed to how it functions. According to China’s Patent Law, a design is defined as “the shape, pattern, or the combination thereof, or the combination of the colour with shape and pattern, which are rich in an aesthetic appeal and are fit for industrial application.” However, it should be noted that Trade Marks and parts of a design which cannot be used or sold separately cannot be registered.

In addition, two products with different functions but which appear the same may be covered by the same design patent. For example, the same design patent could apply to two generations of mobile phone with the same external appearance but different functionality. The only condition is that all products covered by that design patent have to be capable of being sold or used independently. As such, retail spare parts can be protected by design patents in China.

Utility models

If design patents are seen as compliments to invention patents, utility models can be viewed as their lighter alternatives. By formal definition, utility models are granted for new technical solutions relating to the shape and/or structure of an object; in practice this covers most of the requisites of an invention patent, excluding non-material innovations (i.e. operational processes). The major difference between the two is that utility models require a lesser degree of inventiveness.

This similarity in scope has resulted in mass application for patents under a ‘double-filing’ strategy, whereby a single innovation is applied for under both types followed by the abandonment of the utility model if and when the invention patent is officially granted. This way, the applicant can benefit from the early patent protection granted by the utility model (usually approved within one year as opposed to three to five years), as well as the longer term protection granted by the invention patent (exclusive rights for twenty years as opposed to ten). However, this is not just a loophole for gaining protection as soon as possible: the official procedure requires that parallel applications be filed on exactly the same day accompanied by a declaration that such a filing was made.

Managing assets under China’s patent laws

It is extremely important to consider the unique features of the Chinese patent system for any business with an evolving portfolio of innovations. Pre-emptive action is not just recommended but a must, given that patentability requirements include non-disclosure of an innovation: it cannot be publically published anywhere in the world prior to application. Additionally, for any potential invention patent, it is recommended to undertake the double-filing route to gain protection as soon as possible. Double-filing means that the company applies simultaneously for an invention patent and a utility model patent. Since utility model patents are granted faster than invention patents the company could start enjoying utility model protection while waiting for the invention patent to be granted. The market value of technology can only be assured if it has enforceable protection.

South-East Asia IPR Basics Series: Semiconductor Designs in Malaysia

ji2_092Semiconductor topographies, or integrated circuit layout-designs (as they are known in Malaysia), are configurations of computer chips and other semiconductors which determine how they function. Layout-designs are specifically excluded from the list of articles which can be registered as industrial designs and are afforded their own category of protection, which is governed by the Layout-Designs of Integrated Circuits Act (2000).

South-East Asia IPR Basics Series: Trade Secrets in Malaysia

IP TheftIn Malaysia, no pure information can be considered property. However, as a party to TRIPS and other agreements, Malaysia does have laws which prevent the unauthorised disclosure of information. This information is commonly referred to as “trade secrets,” although it is called “confidential information” in Malaysian law. This definition means that trade secrets cannot be proactively registered, but can form the basis of action taken against others. Confidential information in Malaysia can also take the form of virtually any other confidential information which was secret and protected by contractual agreements.

South-East Asia IPR Basics Series: GIs in Malaysia

Photo Andrea Parrish GeyerGeographical indications (GIs) are any type of symbol, mark, etc. which is used to identify the country, region, or area from which goods originate and to which is assigned a given reputation. For example, Champagne is one of France’s most famous GIs, and goods marked as Champagne must be produced in the Champagne region and are reputed to be of high quality. Similar products not from the area must content themselves with descriptions such as “Made in Champagne-style” or “sparkling wine.” Malaysia boasts some indigenous GIs, such as Sarawak Peppers and Sabah Seaweed. In this article we’ll be looking at how you can protect your GIs in Malaysia.
