Recently, an increasing number of opinions from the State Intellectual Property Office ("SIPO") indicate that applications for patent protection for some inventions do not fall under the scope provided in Paragraph 2 of Article 2 of the PRC Patent Law, which defines an "’invention’ as any new technical solution relating to a product, a process, or improvement thereof." Thus, to understand what inventions can be patented, numerous terms such as “technical solution” must be properly defined.Continue Reading Inventions Defined under PRC Patent Law

The United States Supreme Court finally issued its decision on Bilski v. Kappos just before it shut down for the summer. As widely expected, the justices unanimously agreed that the Bilski claims are abstract ideas which are nonpatentable and the Court of Appeals for the Federal Circuit properly rejected the claims. However, the court’s decision, authored by Justice Anthony Kennedy, left many dissatisfied as it declined to clarify limitations on the patentability of business method claims. The high court simply rejected the Federal Circuit’s view that the machine-or-transformation test was the exclusive test for patentable process claims and instead, looked back to the last century, to its cases of Gottschalk v. Benson, (1972), Parker v. Flook, (1978) and Diamond v. Diehr, (1981) to find the “guideposts” and §100(b) the Patent Act for the definition of “process”.Continue Reading Bringing the U.S. patent regime closer to China’s? Bilski v. Kappos

Patent ownership disputes arise, when a party challenges the ownership of a patent right at the State Intellectual Property Office (SIPO) and files suit with the People’s Court to seek rectification of the ownership of the patent. Article 135 of the General Principles of Civil Law of the PRC (Civil Law) provides that "unless otherwise stipulated by law, the statute of limitations to file civil actions with the People’s Court shall be 2 years." The PRC Patent Law (Patent Law) provides no specific provision regarding the statute of limitations in patent ownership disputes. Hence, issue arises as to whether the court can, upon the defendant’s request, dismiss the plaintiff’s claim for patent ownership due to the statute of limitations for civil actions.

To many foreign companies, China remains attractive as the world’s largest potential market for pharmaceutical products. As such products rely heavily on the protection of intellectual property rights, it is essential for foreign companies in this field to adopt a combination of IP protection methods to formulate a strategy for their products in China. To this end, China has established a relatively comprehensive legal system in relation to IPR protection where intellectual assets are protected by way of patents, trademarks, copyrights, and trade secrets.

In patent prosecution, an examiner often mentions the term "common knowledge" when evaluating a step forward in an invention, as one cannot patent common knowledge. Common knowledge in the IP sense is generally a fact known or ought to be known to one skilled in the art and can be applied by such a person to solve specific technical problems. Common knowledge can also be a technical means that is most likely to be considered and applied by one skilled in the relevant technical field when working on solutions to specific technical problems. As China’s Guidelines for Patent Examination (the "Guidelines") do not provide a clear definition for "common knowledge", the examiner and the applicant or the applicant’s attorney often disagree on what is common knowledge in a particular patent dispute.
