China Law and Its Development

Patent due diligence in technology company acquisition

China patent due diligence

A technology development and patent portfolio management strategy may include patent due diligence to evaluate the intellectual property of others to gain freedom to operate in a given technology field. Especially when you are cut a transaction in China, it's important to first look at the Target company's patent information. Our China Patent lawyer reminds you to do patent due diligence in merger and acquisition activities.

An important goal of the acquisition due diligence process is to assess the strategic value of the patent portfolio to the Target Company’s business, including the extent of the exclusivity in the marketplace that these assets provide. As experience China lawyer of patent law, we provide full patent law service to international clients.

Ideally the Target Company has already mapped its patent portfolio to its products and services, showing which parts of the patent portfolio protect what lines of business. Unfortunately many companies have not done this basic analysis and because it can be time consuming it might not be practical to do in the short calendar time in which acquisition due diligence takes place. In a future post we will examine various approaches to address this problem.

Examining the strategic value of a patent portfolio provides insights into the potential “upside” that the portfolio may provide.


China Patent Protection

China patent protection


A patent is a monopoly right granted by a national or regional patent office to an inventor who has created something new under Chinese law, useful and non-obvious; e.g. an innovation in the pharmaceutical sector that results in a new headache pill or a new technology used in computer hardware. Obtaining a patent to cover an invention or new technology enables its creator to prevent others from using, selling, manufacturing or otherwise copying the innovation without permission for a limited period (generally 20 years, subject to the payment of maintenance fees). In return, the patent owner discloses details of the innovation behind the invention as part of the patent application, thereby ensuring that the technology enters into the public domain where it can be used freely once the patent expires.

This is a basic introduction to patents and the patenting process.

By providing the patent owner with a legal means to prevent others from exploiting the protected invention, patents provide a crucial method for inventors to obtain a return on the investment in research and development that led to the creation of that new technology.


Legal comments on China Supreme court's ruling in favor of Michael Jordan on his name v. trademark case

China Supreme court Michael Jordan case

Copyright is the exclusive legal right, given to an originator or an assignee to print, publish, perform, film, or record literary, artistic, or musical works, and to authorize others to do the same. A name is not a literary, artistic or musical work and therefore cannot be granted copyright protection.

A name can be trademarked, however. A trademark is a symbol, word, or words legally registered or established by use as representing a company or product. If the word or words comprising a name is used as a trademark for a company or product, you cannot use that name for a competing or related company or product in such a way that it would likely cause confusion for the typical customer.

For example, if someone uses the name “John Smith” as a trademark for suitcases, you would be committing trademark infringement if you were to sell your own brand of suitcases under the name “John Smith.” If someone has trademarked her name “Mary Jones” for her restaurant business, you would be committing trademark infringement if you opened up your own restaurant named “Mary Jones”. You could, however, open a car wash named “Mary Jones” if no one else had previously trademarked the name for that type of business.
