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.

Last time Thomson Reuters added major updates to the Thomson Innovation system, the non-patent literature collection for the system was expanded to included Web of Science content back to 1898. The August 2012 update also included new and enhanced features like full-text article linking, ordering, and document delivery, enhanced ability to analyze non-patent literature, new literature search fields, and watched records for citation changes. As of October 27, another set of updates for the system was included in Thomson Innovation Release 3.6. This release includes a new simplified Chinese interface, coverage for Chinese granted patents translated into English, extended coverage for English-translated Japanese granted patents and applications, Native Japanese patents to fill in gaps for other Japanese collections, EuroPCT transfer record gaps populated with claims from corresponding WO records, and in-line editing now available for Custom Fields.
After the jump, learn about the new simplified Chinese interface, translated Chinese granted patent coverage, and other new features available from the October 2012 release of Thomson Innovation!

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
, Surf IP
. 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!

Search Chinese journals, dissertations, conference proceedings, information on Chinese companies and products, data from Chinese scientific institutes, policies and laws of China, Chinese patents, and national/industrial standards all through one portal: WanfangData.com
. The search portal is available in both English and Chinese. According to the About section
of the website, “Wanfang Data has been a task force of the Institute of Scientific & Technological Information of China (ISTIC), the Chinese Ministry of Science & Technology, since 1950s.” The site is subscription-based, but free limited search options are available on the Chinese version of the website. Users can also request a trial
for the English version of Wanfang Data portal.
After the jump, learn about the Chinese patent and non-patent literature available through both the English and Chinese-language versions of Wanfang Data!

is a free Chinese patent search site, created by Wisdom buds Information Technology (Suzhou) Co., Ltd, which managed to surprise me multiple times. The site is only available in Chinese, so I’d recommend translating the site interface through a free online translation service
(like Google Translate or Bing Translator
), and search queries should also be translated into Chinese before being entered in the search form (although English abstracts are available, so English queries do produce results). Native Chinese speakers will have an easier time utilizing this search site, but I’d still recommend that any prior art searcher test this site due to a few surprisingly useful features: broad coverage (including Norwegian patents), a wide variety of search forms (including a command-line interface
and a batch search form), and both Chinese and English abstracts are available in the full record format. Other useful features, such as a bulk download feature, patent analysis functions, and the option to email records to other users, only seem to be available to registered, paying users.

If Chinese non-patent literature searches
are difficult for English-language prior art searchers, you can imagine how challenging chemical and genetic sequence searching within Chinese patent documents can be. Many tools for chemical
and genetic sequence
searches in patent documents are available, both for free
and by subscription
, and many tools also exist for searching within Chinese-language patent documents
. Few tools, however, combine the Chinese patent coverage and chemical/genetic sequence search options; we’ve looked at only one subscription-based genetic sequence search tool, GenomeQues
t, which recently added Chinese patent sequence data
to their collection. Today we’ll look at two free tools that can be used by English-language searchers to locate chemical names and genetic sequences within Chinese patent documents: ChemYQ
After the jump, learn more about the Chinese chemical search engine ChemYQ and the Chinese genetic sequence search site NASDAP!

is an intriguing patent search platform with a lot of interesting features and a few major drawbacks. The search interface is available in both English and Chinese, and non-registered users can perform most basic search functions for free, although full-text patent views, patent analysis functions, and permanently saving search histories and projects are reserved for registered users. The most impressive feature of Patentics is the ability to re-rank search results according to relevancy in relation to a specific patent document or index word. If a searcher finds a particularly useful patent within a list of results, this function can help them locate similar patent documents within the results. Users can also browse through an index of concepts related to a specific keyword, which can help the user expand the query. The concept index offers searchers an alternative to looking in a thesaurus for synonyms; now the searcher can check mark all terms that relate to the concept and automatically create a broad query that will retrieve more relevant documents. One major issue exists for this search site, though: it seems impossible to register for an account on the English-language interface.
Read on the learn about the relevancy and concept search features of Patentics, as well as how to how to register for the site!

Following news that Dialog is now offering SciPat’s full text database of English machine translations for Chinese patent documents, I’ve been taking a look at some free sources of Chinese patent information on the web. It’s a somewhat confusing landscape for the English language searcher trying to make sense of the Chinese patent search offerings, but there are a number of players to note.
