How to Use PatentOptimizer™ Analytics to Filter Documents and Locate Keyword Variants within a Patent Result Set

LexisNexis® PatentOptimizer™ is a patent analysis tool created by LexisNexis, and it was designed to assist patent attorneys and agents when drafting patent documents.  The PatentOptimizer™ Analytics feature may additionally be of use to patent searchers, who can load a set of up to 2000 documents into the Analytics tool and granularly filter the result set by a wide variety of criteria in order to locate very specific subsets within the broader result set.  Searchers who have narrowed their result set down to a list of hundreds of relevant documents can use the Analytics tool to locate only key documents through the filter options. The Analytics tool can also be used to generate a thesaurus on the fly for selected sets of documents and locate all variations of each term/phrase listed in the thesaurus.  This feature may be used by searchers to identify various important keywords and synonyms in a relevant result set in order to expand their search queries.  In general, PatentOptimizer Analytics offers tools that can help patent searchers either narrow their result set (through the filters) or expand their result set (through the keyword variants in the on-the-fly thesaurus).

I recently had the opportunity to watch a demonstration of PatentOptimizer™ Analytics, so continue reading for an overview of the filter and thesaurus options which can help you narrow or expand your patent search results set!

Will cloud computing radically change patent search products?

First, let me say that I think “patents on the cloud” is a radical idea, and something that may create some changes in patent information products.  Read on for a summary of Alexandria, a new product that provides “patents on the cloud,” and my analysis of this new approach!

I recently spoke to Mike Baycroft of Fairview Research, Inc., the company that has lately acquired IFI and launched a new patent information product, Alexandria, billing the service as “Patents on the Cloud.”  Alexandria is a database of patent information hosted on the Amazon Elastic Compute Cloud, ready to license.   For those who haven’t followed the jargon, the “cloud” refers to cloud computing, and it basically means that you can get a lot of stuff, like data and software, directly from the delocalized network (or “cloud”) of sources that make up the internet, rather than having to load it on your own local servers.

Are you catching reassigned US patents in your search?

Update: This post has been edited to reflect that PatBase is jointly operated by Minesoft and RWS Group.

Experienced patent searchers know that searching for patent databases by company name is hard – and I mean really hard.  A company which owns a patent is called the patent “assignee” in the US.  Take a look at our assignee best practices wiki article over on the main Intellogist site to get an overview of some of the obstacles that can trip you up during this kind of search.

One thing that makes patent owner searching so difficult is simply that patents change hands, and when they do, the information published on the patent face is no longer correct.   Another difficulty is that these types of transactions are not always on record at the USPTO.  However, the USPTO does keep a US patent assignment database of all the transactions that they *have* been notified about.   And fortunately, patent search vendors can update their electronic databases with the new assignment information.  (by the way, as far as I know, US reassignment data is the only reassignment data that gets collected and added into commercial patent search products on a regular basis.)

Here is a quick summary of what some major commercial providers do with US reassignment data:

Boy, the WIPO news keeps coming! This time, WIPO in partnership with LexisNexis, Minesoft, ProQuest, Questel-Orbit, Thomson Reuters and WIPS (a veritable patent search system all-star lineup) has announced the Access to Specialized Patent Information (ASPI) program. What is this patent acronym program backed by more than a half dozen groups you may ask?

ASPI is an initiative to provide free or low cost access to patent search systems and tools to IP offices, universities and research institutes in developing countries. The patent search systems chosen for this program are:

For more info on the program, including eligibility requirements and why this makes sense for the global IP community, read on!
