September 17, 2018September 17, 2018 Chinese, Japanese, and Korean language publications account for 43% of new CAplus database records in 2010 New Publications in Chinese, Japanese, and Korean Languages, Percentages of Publications In 2010, Chinese, Japanese, and Korean language publications accounted for 43% of new CAplus database records. That’s at least a 10% increase over the last 3 years. For 2010, out of 503K new patents, almost 300K are from CN, KR, JP; so nearly 60% for patents in From journals, 295K out of 869K or 34%.

Chemistry Patent Publications, 1999-present
September 17, 2018September 17, 2018 Patenting of new chemical research has accelerated, especially patenting of Chinese chemical research Chemistry Patent Publications, 1999-present Over the past three years, China has emerged as the world’s leading source of chemically related patents, as reflected in the CAS databases. Note: IP-savvy audience members might notice that this chart’s distinctions are based on new (basic) publications, which are mostly published applications, not granted, patents.

CAS continues to uncover new small molecules in significant numbers
September 17, 2018September 17, 2018 CAS continues to uncover new small molecules in significant numbers Small Molecules in CAS REGISTRY, Small Molecules (Millions) Begun in the early 1960s, the CAS REGISTRY has, in the last six years ( ), more than doubled the number of small molecules in its collection, reflecting the disclosures of new small molecules by authors, patent inventors, and chemical catalogs, regardless of publication type or media form. About a year ago, CAS registered its 50 millionth substance. Reaching the 50 million mark so quickly was seen an indicator of the accelerating pace of scientific knowledge. For instance, it took 33 years for CAS to register the first 10 million compounds, which happened in But last year, CAS registered 10 million in less than a year. In 2010, REGISTRY added another 5.6 million unique organic and inorganic small molecules. Let’s take a look at where all these compounds are coming from….

What were the sources of these molecules in 2010?
September 17, 2018September 17, 2018 What were the sources of these molecules in 2010? Sources for CAS REGISTRY, 2010 Number of Small Molecules One reason for the growth, and we’ll talk about it later, is that CAS has recently broadened its indexing policies to cover exemplified prophetics in patents. But, years ago, all compounds in the Registry came from learned journal articles and patents, but that’s changed. Now we have compounds in the Registry from commercial chemical suppliers (our CHEMCATS database), national inventories of chemicals in commerce, like the TSCA inventory, and reputable web sources Still, by far the largest contributor to new compounds in the CAS Registry is the journal and patent literature. As we just saw, the Pacific Rim, especially China, is growing by leaps and bounds. Let’s take a quick look at these sources individually Sources CAS is a division of the American Chemical Society Copyright 2010 American Chemical Society. All rights reserved.

Percentage of New Compounds added to CAS REGISTRY from Patents
September 17, 2018September 17, 2018 Increasingly, new chemical discoveries are being disclosed through patent activities Percentage of New Compounds added to CAS REGISTRY from Patents 46% Percentage of total The monetization of chemical information will continue…. As you can see from this chart, in the past 30 years, the number of new compounds disclosed in patents, as a percentage of all new discoveries, has increased dramatically. Clearly, the capital markets, private investment, and the intellectual property systems around the world are playing an increasingly important role in chemical information. 14% Year *CA Database annual average is 23% patents CAS is a division of the American Chemical Society Copyright 2010 American Chemical Society.

CHEMCATS continues to grow and remains a source of new small molecules
September 17, 2018September 17, 2018 CHEMCATS continues to grow and remains a source of new small molecules Number of Catalog Products and Unique Substances in the CHEMCATS Database Number of Products/Substances In CHEMCATS, products (blue line) and available unique chemical substances (white line) continue to grow. These commercially-available substances come from 1215 catalogs from more than 1100 suppliers. CAS updates this database on a weekly basis in order to keep it as up to date as possible. 10/1/10 products – 43,324,884 Unique RNs – 11,904,425 12/1/10 Products – 43,167,336 Unique RNs – 12,476,076 Number of Unique Substances CAS is a division of the American Chemical Society Copyright 2010 American Chemical Society.

September 17, 2018September 17, 2018 What criteria must a substance meet to be included in the CAS REGISTRY? A substance must be Identified by CAS as coming from a reputable source, including but not limited to patents, journals, chemical catalogs, and web-based substance collections Described in largely unambiguous terms Characterized by physical methods Described in a patent document example or claim Consistent with the laws of atomic covalent organization Talk thru this slide, emphasizing the focus on evidence that the substance has been made CAS is a division of the American Chemical Society Copyright 2010 American Chemical Society.

September 17, 2018September 17, 2018 CAS chemists interpret when compounds are described in terms other than singular structures or names The challenge here for the CAS analyst is that the compound at the bottom of the page is described as the “methoxyamino urea product” of a substance. So the analyst has to combine structural data with name information to create the Registry Record. CAS is a division of the American Chemical Society Copyright 2010 American Chemical Society.

September 17, 2018September 17, 2018 Since 1997, patents have provided more new small molecules than have journals CAS analysis of a typical PCT application 917 indexed compounds from Examples and Claims 576 new compounds added to CAS REGISTRY 613 single-step reactions 5,394 multi-step reactions 1,029 reaction participants 2,119 substituent definitions for Markush structures added to MARPAT® CAS is a division of the American Chemical Society Copyright 2010 American Chemical Society.

September 17, 2018September 17, 2018 Patents regularly describe substances in ambiguous ways: In WO , this “desired product” is fully characterized CAS RN As it turns out, this is an interesting example of CAS’ efforts to represent chemistry correctly. The CAS analyst had to go back to the original journal article, from 1998, to correctly resolve the substance described. That journal article showed that there was an inversion of the stereochemistry during the reaction at the site of the nitrobenzoate substitution, a detail not noted in the patent at all.

Chemical libraries are the second-largest source of new molecules
September 17, 2018September 17, 2018 Chemical libraries are the second-largest source of new molecules What are chemical libraries? Often a collection of drug-like small molecules to be used as leads in high-throughput screening or industrial manufacture Each substance has associated information stored in some kind of database, such as the Chemical structure Purity Quantity Physiochemical characteristics What is a chemical library? Essentially a diverse library of drug-like small molecule leads Diverse: minimal clustering in chemical space Drug-like: e.g. aqueous solubility and intestinal permeability ("rule of five”, polar surface area) Lead: small, MW , room for optimization Can also be more focused to cover a selected region of chemical space Libraries at the HTC Tripos ® 6000 compounds ChemDivT compounds includes a subset of 3000 compounds containing a NH 2 group ChemBridgeT compounds includes DIVERSet T compounds and CNS-Set compounds Additional obtained Spectrum Microsource drugs, including FDA-approved 2000 compounds Total of compounds today Screening libraries Sysbio/reagents Nanoparticle library.
