    Chinese Courts Cares More About Patent Quality Now (A Doctrine of Equivalents Story)

    December 13, 2022

    There is no doubt that the drafting quality of a patent can be crucial in determining the success (or failure!) of the patent during litigation. However, due to various reasons, patents often fail to use the right drafting strategies that best protect the invention. Too often, inexperienced or unsophisticated patent drafters merely listen to an inventor and literally describe the features of an invention. Worst yet, some inventors try to draft their own application, making the similar mistake of describing an invention too specifically and narrowly, leaving plenty of “design-around” space. Even though a patent may grant, the protection scope for that invention is weak, at best, and may even…

    October 19, 2022

    Previously we published an article about CNIPA rejecting a patent application claiming a food that could also be used to treat or prevent diseases based on the food’s alleged non-compliance with Food Safety Law. China’s Food Safety Law includes a provision which states any use of a composition as a food must be strictly separated from any medicinal use. Recently, we have noticed a worrying trend of such “food safety” type rejections impacting a broader class of inventions, even for inventions that are not directed towards the food itself. Here is one such case. Manufacturing Methods for Making a Plate The patent application[1] at issue is directed towards a method…

    China’s Supreme People’s Court (SPC) Hands Down First Patent Linkage Appeal Decision

    September 21, 2022

    China has been implementing a plethora of new laws and measures that are particularly favorable to drug companies, such as patent term extension and patent linkage.  Details of the new implementation measures for patent linkage (technically “early dispute resolution mechanisms for drug patents”) came into effect on July 4, 2021. At around the same time, China’s public registration system for innovator companies to list patent associated with marketed drugs (China’s version of the US FDA’s “Orange Book”) began accepting registrations.  It has been close to one year since these mechanisms were put in place. The first legal decisions from these patent challenges are now coming out, and the first appeal…
