How much does it cost to file a patent in India?

What is your fee structure? — Unlike law firms, we do not charge our clients on an hourly fee basis. In patent enforcement matters, we represent clients strictly on a contingency fee basis. The fee structure is based on several factors, most notably, size and complexity of the case.

 

Should I disclose my invention? – Disclosures to friends and family are usually not problematic with respect to bar dates because they are not public and they are done under an expectation of confidentiality.  On the other hand, the less disclosure the better, at least until a patent application is filed on the invention.  It is not at all uncommon that someone will accidentally either reveal something that was told to them in confidence or will say something that somehow triggers a third person to invent the technology themselves.

The best protection, and to some extent the only reliable protection, is to get your patent application on file by filing at least a provisional application.

 

How long will it take for you to complete your analysis of my patent? — This depends in part on the amount and the quality of information we receive from the inventor or the patent owner. The preliminary evaluation usually takes a week. 

 

What is this evaluation process going to cost me? — Nothing. All costs for analysis and evaluation are borne by us.

 

How much does it cost me if I decide to go with you?  — From search to issuance a patent typically costs Rs. 2,000 onwards and can be much higher for IT or chemistry-based patents.  A basic Patent Filing Cost Calculator is available at http://lexgin.com/ 

It is good enough to give you an idea, however it is recommended that you talk in person without any hesitation. Patent Agents can surely be trusted. Ask for a NDA (Non-disclosure agreement if in doubt). The fees depend on the complexity of the invention and it is always better to discuss in person.
