Secure competitive advantage in China – STN now offers comprehensive Chinese patent information

New: FIZ Karlsruhe implements Chinese full-text patent file CNFULL on STN / full-texts of Chinese patent applications, granted patents and utility models available in machine-translated English / unique numeric property search feature enables users to search for chemical and physical properties

With China having grown into one of the world’s major patenting countries, it becomes extremely important for all companies involved in R&D to keep an eye on the developments in Asia and at the same time to protect their products and inventions in this region accordingly.

The new full-text patent file CNFULL offered by FIZ Karlsruhe, the European Service Center of STN International, enables researchers and patent specialists to broaden their complex patent searches to Chinese patent full-texts in order to determine patentability, state of the art, infringement, and licensing possibilities.

“With CNFULL we offer our customers a valuable resource of patent information from one of the world’s most dynamic economic areas,” says Rainer Stuike-Prill, Vice President Marketing & Sales at FIZ Karlsruhe. “The excellent search, retrieval and analysis tools of STN allow for precise searching and retrieval of business-critical information. The new database provides our customers with an overall picture of the Asian patent landscape, thus helping them to secure their competitive advantage.”

At present, the file comprises over 4.5 million records and more than 3.8 million images from 1985 onwards. More than 10,000 new documents are added to the file each week. Each database record contains all documents published for one application. Online thesauri for the International Patent Classification (/IPC) and the European Patent Classification (/EPC) are searchable. Abstracts are initially machine translated and replaced three months later by human translated text; descriptions and claims are machine translated.

The unique Numeric Property Search feature, developed by FIZ Karlsruhe and already used in other full-text patent files on STN, is also available in CNFULL. It enables users to search the numeric values of over 30 physical and chemical properties in almost 400 unit variants within the full text of all documents and thus significantly enhances the search precision in many cases. Searchable properties and their respective base units comprise for example /SAR (Surface Area, m²), /CMOL (Molar Concentration, mol/L), /DEN (Mass Density, kg/m³), or /VOL (Volume, m³).

CNFULL is a valuable addition to STN’s wide range of full-text patent databases from all over the world. It shows once more that FIZ Karlsruhe provides excellent services to science and business, as confirmed recently by an international auditing group. 35 years after its foundation, FIZ Karlsruhe is dedicated to its motto “Advancing Science”, against which its products and services are measured.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
