Benefits of Filing Patent Applications in India

Some of the benefits of filing patents in India are as follow:

Cost of Filing Patent Application in India

The cost of filing patents in India is extremely low as compared to other countries due to lower government and professional fee. The overall cost of filing a patent in India from “Filing” to “Final Decision” lies within the range of USD 1500-2000.

Language of Patent Applications

Applicants can file a patent application in English or Hindi at the Indian Patent Office (IPO). Therefore, additional translation efforts or translation fees are not required.

Reduction in Official Fees

The Indian government has taken initiatives to increase filings by reducing fees for PCT applications as well as MSMEs & Start-ups.

Comparative Study on Patent Databases

Sagacious IP performed a comparative study on the quality of patent search in India. The study evaluated the readiness of India in the field of patent search and analysis. We conducted three types of searches on paid patent databases. Furthermore, we compared the results with a similar search on Indian Patent Office’s search engine.

Classification-based Search

During this search, we compared IPC classifications tagged by examiners of other countries vs. Indian examiners vs. actual relevant classification for the same technology and same patent families. Thus, it helped us gauge the accuracy of IPC classifications in Indian patents that have been granted.

The Indian patent office has a restrictive search engine for searching IPCs. Therefore, it is advisable to use paid databases and truncations to get maximum results if the search strategy is based on classification.

Assignee-based Search

The engine of patent search in India does not have the corporate tree function. If a search strategy is based on Assignee, then we recommend you to use paid databases and the associated corporate tree function in the databases to get maximum results.

Keyword-based Search

Our keyword-based search was restricted to the Indian jurisdiction and helped us understand the coverage offered by various databases to do patent search in India. Therefore, if the search strategy is based on keywords, it is advisable to use paid databases and truncations to get maximum patent results.

Legal Status of Indian Patents

Legal status of patents in the Indian Patent Office (IPO) can be categorized as:

  1. Alive & Granted
  2. Alive & Pending
  3. Dead & Lapsed
  4. Dead & Expired

Our study showed that the legal status of patents in IPO is more accurate than other paid databases. Therefore, it is advisable to refer to the legal status displayed on IPO when working on critical FTO or product-based searches.


Patent searching has always been instrumental for inventors and organizations around the world. A good patent search involves a combination of broad and narrow approaches to cover all the relevant patents. If the search strategy does not include spelling variations, synonyms of keywords, parallel search strategies, then the strategy becomes too narrow and relevant patents tend to be missed.
