Google has expanded their power of search into U.S Patent searching. The latest Google service - Google Patents search a total of 7 millions patents from the year of 1790 to the present.

The interface is similar to the earlier controversial Google Book Search. I love Google because they always bring up somethings new that other search engines have not think of it.






There’s nothing new in the patent search industry. The US patents office itself has a great and precise search engine to allow users to make DB searches on all registered patents in the US.
I don’t think there’s anything special in this, the only difference is the UI. But people doing such in-depth form of searching wouldn’t be concerned on search UI as many have grown to accept the US Patent Office’s UI for a long time.
Just my two cents!
