Quick answer
A PCT (Patent Cooperation Treaty) application, administered by WIPO, lets you file one international patent application and decide later, at 30 or 31 months from your priority date, which countries to seek patents in. Indian applicants usually file it within 12 months of their Indian application, with the Indian Patent Office as receiving office. CorpBridge's professional fee is ₹24,999 plus GST, with WIPO and search fees on top; patent work is handled only by registered patent agents.

What is PCT International Patent Application?
There is no single 'world patent', but the PCT comes close for the early stages. One international application, filed in English with the Indian Patent Office (or directly with WIPO), has the effect of a filing in every PCT member country, which covers more than 150 countries.
You get an international search report and a written opinion on patentability, and up to 30 or 31 months from your first filing date to decide where to enter the national phase. That gives you time to test the market, raise funds or find licensees before paying for individual countries.
Most Indian applicants file a provisional or complete application in India first and then file the PCT application within 12 months, claiming the Indian priority date. Indian residents must also comply with Section 39 of the Patents Act before filing abroad; we handle that too.
