How can Indians file a patent internationally?

There is no such thing as a ‘global patent’ that is acceptable worldwide. You have to file separately either through the Paris Convention or Patent Co-operation Treaty System. With this, your application will get the acknowledgement of an international patent.

Paris Convention– For all member countries enlisted in the Paris convention, an applicant can file directly in the corresponding country within 12 months from the date of filing that is the Priority Date.

Patent Co-operation Treaty– In this system an applicant can file the patent application in the PCT contracting states within 30-34 months from the Priority Date ( here is an exception to the usual 12 months’ time frame from the Priority Date). You must note that all formal works are done in the form of documentation and simplified logistics. Through the PCT system an applicant can also get to know the International Search Report of his invention. However, an applicant must be aware that the PCT application itself must be filed within 12 months from the Priority Date. Also, know that every Paris Convention country may not be a member of the PCT contracting state. For filing patent applications in those countries; applicant has to take help of the Paris Convention.
