China still needs to redouble its efforts to develop acme technologies such as optics, engine turbines and medical equipment, said an official from the State Intellectual Property Office (SIPO) during a recent press conference.

"We are still at a disadvantage in core technologies," said Bi Nan, director-general of the Planning and Development Department of the SIPO.

During the first half of this year, the SIPO received 23,000 patent applications based on the Patent Cooperation Treaty, with 21,600 of them coming from domestic industries, signaling a rise of 7.6 percent year on year.

Among the 35 sectors classified by the World Intellectual Property Organization, patents granted to domestic inventions outnumbered those to foreign applications in 32 categories.

At the same time, Bi pointed out, Chinese entities were not as competent as their foreign counterparts in view of receiving long-term patents whose validity could extend more than 10 years. The comparison was especially obvious in 28 of the 35 sectors, including transport facilities and computer science among others.

"Therefore, we should endeavor to improve the quality of patents, keep mapping out critical inventions in key areas and continue to reinforce the protection and utility of patents in important sectors," she said.
