Invalidation Search – Get hold of German Patents

English search….

80% of people are dependent on that.

There is so much technical literature available in non-English speaking countries that its equally competent to English literature available..

Japanese
Korea
Taiwan
France, and
Germany is one of them

So lets take Germany this time…

How to catch German patents for an invalidatoin search.

There is a very good German website Patents-de

If you know German you can directly search in there, however, if you are not use Google Translation

Paste the link of the German patent website in the box and translate the page to English. Like you can see here

Now can you see the difference between German and English site

Now put the keywords in German and you can see your answers in English!!

isn’t it Great!!

Enjoy Invalidations…

Invalidation Search – European Classification

Many people use class based search, I have also mentioned it as one of the base strategy.

What I would suggest is after you done a thorough search in IPC and US classes you should also go for ECLA – European Classification.

You can search for your relevant ECLAs here

European Classification has been derived from IPC and is narrower than that. So the chances of digging into narrower domain are easier.

Benefit: Increased relevancy
Disadvantage: Search scope limited to European patents

Believe me it would be a beneficial strategy for you…

Invalidation Search – More Keywords

Invalidation, Invalidation and Invalidation…

I am sorry for not being on roll for sometime… you know when you receive an invalidation you cannot think of anything else other than invalidating that patent with a prior art…

So I’m back again with lots of new strategies.

I think, it’s a big limitation that the scope of the invalidation search is limited by the words that the searcher can think of…

However, the art of search says that you have to find a literature that has not necessarily been described in the same words that you are using.

So the question arises, how to come up with new words?

Google Sets!!

Though it is still in labs but it is very useful.

So now you have more related keywords!!

Google Sets identifies new keywords from 1000s of WebPages available on Internet. Now the good point of this strategy is that you get to know about lots of related words that are being used and written by other people around the world.
