Advanced Patent Search (Secondary Search)


Now we introduce how to conduct a Patent Search using MINING function. MINING function enables user to narrow the search result to more less noisy region or interested region.

So it can step up the productivity of the patent searching. And the history of the mining are all saved, and we can access the history anytime. Therefore we can deal in huge search results using combinations of many conditions by try and error.

For example we create a search result of U.S. granted patents search by a keyword "computer".

Secondary Search (Filtering Search)

Then click the "MINING" button on the above of the overview area (MINING function is also available in compendium view).

Click MINING button

Then secondary search function will be open. MINING function automatically retrieves top bibliographic candidate of this search result.

In the following picture, it means there are 257845 patents having G06 IPC-8 classification and 147972 patents having H04 IPC-8 classification etc... in this search result. We can choose classification type by IPC-8 or USC (U.S. patents). And we can choose classification layer (section, class, subclass etc...).

Secondary search of IPC8.

We can show the candidate from assignee, inventor and patent attorney. To show such person candidates, click the person icon placed on the tab in the mining function. In the following picture, it means there are 35721 patents filed by IBM and there are 14887 patents filed by Intel etc...

Secondary search of Assignee.

We can show the term (filling date, publication date, registration date) candidate. To show such term candidate, click the calendar icon placed on the tab in the mining function. In the following picture, it means there are 1801 patents filed in between 2008 and 2009 and there are 9847 patents filed in between 2007 and 2008 etc…

Secondary search of term.

We can narrow the search result down to some population by some free key words. To use this function, click the word icon placed on the tab in the navigation function. We can specify fields of this searching from title, abstract, claim, specification and full-text.

Secondary search of term.

MINING Function

Now we narrow down this search result by assignee "Intel". To narrow down, "Double Click” the label "Intel”.

Narrow down by assignee Intel.

Then filtering processing will start.

Filtering processing.

Now we narrow down this search result by assignee "Intel". To narrow down, "Double Click” the label "Intel”.

And the button Intel was shown. This button means current search result is narrow down by original search result by Intel.

Completion of narrow down by Intel.

Then we narrow down this population by filling date between 2006 and 2007. Click the calendar tab and "Double Click" the element "2006-2007".

Narrow down by filling date.

Then we narrow down original population by assignee is Intel AND filed from 2006 to 2007.

Narrow down by assignee and filling date.

Then the button was changed.

And we can return to the narrow down by clicking the button. For example, we click the "Intel” button to return the population filtered "only” by assignee Intel from original search result.

Return to population filtered only by Intel.

History (Footmark) of the Mining

The footmarks of the secondary search are all saved, and we can easy to duplicate the population anytime.

To show footmark of the secondary search, click the tree button placed on the above of the mining area. Then the mining footmark tree will be shown. To duplicate the narrow down, Double Click the node of the tree (We can double click not only end node (c.f. 165/80.3) but also middle node (c.f. H05).

Footmark of the secondary search.

And the footmark of the mining is also available in MINING tab in the search result control.
