In September 2012, I compared the free patent search options available for Chinese patent documents, and one option was the free English patent search interface created by SIPO. SIPO also provides another free patent search tool called the Patent Search and Service System (PSS), which went online for public testing in April 2011 and currently includes both English and Chinese search options. According to an EPO press release, the PSS includes “a number of advanced search and retrieval possibilities, such as citation and family searches, cross-lingual retrieval, legal status information, full text data and machine translation.” The tool allows users to access CN data on patents, utility models, and designs from 1985 onwards, and the system is updated monthly. Worldwide patent document data covering 97 countries (most likely INPADOC data) also appears to be searchable under the structured search form. The tool is free, but registration is necessary to access many of the more advanced tools of the system, such as viewing the Search History tab and downloading full PDF documents. Unfortunately, registration proved to be a bit problematic for an English-language user, and some features were still not accessible even after registering for the portal.
Read on to learn about the advanced search tools accessible for Chinese and worldwide patent documents on PSS, and also learn about the registration and access problems that you may encounter when using this system.

[tweetmeme source=”Intellogist” only_single=false] Over two years ago, the Intellogist Blog discussed Chinese patent searching on a budget. The free search options for Chinese patent documents included in that post were SIPO, CNIPR/C-Pat, CNPAT, Surf IP and IPEXL. We later published a post on the free Chinese patent search options on Zhihuiya.com. Over the past two years, these websites have all undergone many changes, and some of the search systems are no longer freely available. Surf IP and C-Pat are no longer available online, and Zhihuiya.com is now redirected to CN.Patsnap.com, which only appears to be available for subscribed users. Continue reading to learn about the free Chinese patent search options currently available through the remaining search systems: SIPO, CNIPR, CNPAT, and IPEXL (which draws on SIPO data). If you need a global prior art search conducted by a professional searcher fluent in Chinese, you can always contact patent search professionals who have access to both free and subscription patent databases with broad Chinese patent coverage.
After the jump, learn about the free Chinese patent search options available through SIPO, CNIPR, CNPAT, and IPEXL!

Recently the Intellogist blog discussed GenomeQuest as a source for searching patent sequence data. This month GenomeQuest announced that they are adding Chinese patent sequence data to their collection. The company is adding sequences filed at the Chinese Patent Office (SIPO). The GenomeQuest press release explains that 40,000 sequences from over 5,000 Chinese patents have already been indexed into their GQ-IP product, which contains sequence information from patent collections and public sources such as GenBank, EMBL, and DDBJ.
