While I covered Google Patents in October 2009, here are some video shots. A 22 sec video which can help you decide whether to go for getting a patent or not. By elimintaion prior art search costs, this can greatly reduce the cost and complexity for small entrepreneurs.
So go ahead, patent your R functions and algorithms ( The video shows one important tool) while using the tool at http://google.com/patents to search for prior patents.
Incidentally YouTube has a great feature for promoted videos only open for USD ( incidentally my 2007 email feature is listed as INR so I am still waiting for the free customer support at G Inc to reply that “hey, I can now pay in USD so let me in”.)
Neat Concept, anyways!
I tried this
