Several allegations were made against the search engine giant Google of unauthorized copying or misappropriation of content and ideas. Though they all yet to be proved. Number of time, Google has been considered as villain for copying others content and parasitically overstepping boundaries to profit from the work which is done by somebody else.

Informal allegations have been made against the firm for several times. But none of the time, it has been proved in a formal way. The Books search engine, Google News site and YouTube video sharing site are facing number of complaints of the same and the company have faced copyright lawsuits over these services as well.

However, the role of Google in such issues was reversed on Tuesday when it has made the same allegation on Microsoft. The leading search engine has alleged Microsoft of capturing some of the top Google results for various queries.

Google has also informed that Microsoft has used these data in its Bing search engine. The debate is on and expected to be settled soon as a proper investigation will be done on it.
