You can work with a patent agent or patent attorney to get your patent filed. The first step would be get a patentability assessment done. Been an Indian National you would have to file the Indian patent application first followed by US, else you will have to seek the approval for foreign filing from the Indian Patent Office.
The Indian patent is valid in India, while the one filed in US is valid in USA only, as the patents are jurisdiction based. With online filing system, you can file an Indian/US Patent Application on your own, however, there are certain formats to be followed and formalities to be completed.Thus, it would be better if you work with an attorney. The Indian Patent filing costs around 30-40K depending upon the type of application, number of pages and claims, while a US application is more expensive.
