Google already had a "dumbass" search engine generating revenues. When "smartass" started in 2004, Vringo argued that the immediate jump in revenues of 20% were attributed to the Lang patents. Charts show that since that time one could argue the new smartass Google search engine increased revenues up to 40%, but Vringo's legal team decided to keep it conservative.
Now fast forward 4 years later, I believe there is no way that Bing started using a dumbass search model to compete against the superior smartass Google system that uses the Lang patents. That is why I assumed 100% of Bing's results were exposed to the Lang patent technology.
Now there are the holes in my analysis. 1) I don't know what the % of Bing revenues are US based. Though I think Bing is used less overseas than Google due to the lack of wide spread brand recognition. 2) I used very conservative numbers for revenue. The last quarter of 2012 the online services division of Microsoft revenues was $893 million, which would be $3,600 million annualized for 2013. Lastly, 3) The revenues may or may not include the Yahoo search engine business that Microsoft receives.
The purpose of my analysis is to get a discussion going to apply math to estimate a probable amount for Vringo instead of a raw number of $200 million being bantered about with no basis.
