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.
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.

A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.
The most complete assessment ever of statistical uncertainty within the GISS Surface Temperature Analysis (GISTEMP) data product shows that the annual values...
Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.
The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...
Engineers at the University of Tokyo continually pioneer new ways to improve battery technology. Professor Atsuo Yamada and his team recently developed a...
With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
