  1. An inventor,
  2. An assignee, or
  3. A legal representative of a deceased person.

2. Where to document the patent applications in India?

India provides four patent offices located in different parts of the country – Kolkata, Mumbai, Delhi and Chennai. Under each of the patent office, specific regions have been allocated i.e., territorial jurisdiction, which decides where the patent candidate needs to document their application. The choice of patent office is resolved on the basis of where the candidate (or the primary candidate in occurrence of joint candidates):

  • Lives,
  • Has residence,
  • Has a place of business, or
  • Invention was initially originated

For candidates having no domicile or business place in India, the address for service in India (i.e., patent agents address) will be utilized for deciding the suitable office.

3. Types of patent documenting in India

Upon deciding the appropriate patent office, the following step is to file your patent application. The patent application can be submitted through two modes in India:

  • The e-filing mode
  • Physical Filing mode

3.1 Electronic recording (e-documenting) of patent applications in India

Generally, many patent firms used to physically document patent applications because of the online framework not being extremely solid and the need to not change long standing practices. However, the expansion in expense for paper filings has prompted a great deal of firms now embracing the e-filing system so as to abstain from charging their customers extra government charge.

Now if you are concerned about the quality of the e-filing mode, we can assure that the nowadays the most practiced approach of patent candidates and agents is e-filing process. Throughout the years, the Indian patent office has additionally been moving towards digitization of patent documents and has been requesting patent candidates/agents to utilize the e-filing process. This process will help to remove errors  while checking physical records and making the procedure less demanding, speedier and more productive for both the patent candidates and the patent office.

With the end goal to boost online filings, the Indian patent office has advised that patent candidates will be required to pay an extra 10% government charge for physical filings. Due to this effort a slight impact has been noted where there is a decrease in physical filing and considerable measure of candidates are moving over to the e-filing framework.

Additionally, the online framework has turned out to be more dependable throughout the years and incorporates the options of filing other application too.  The perks of filling on-line wins over the heavy efforts required for preparing form, saving the transportation cost, long que of submission, pay and wait for receipt. In addition, patent candidates are not constrained by the patent office timings and can for all intents and purposes document their applications at suitable time of the day. Further, the candidates situated in different urban communities do not need to travel anyplace and can for all intents and purposes do it effortlessly on the web.

3.2 Physical recording (or paper filings)

Generally the traditional approach for patent filing in India is physical filings and has been a practice for a considerable length of time. In any case considering the perks of e-filing, candidates and patent agents have gained interest in the e-filing framework. Be that as it may, it may not be conceivable to totally kill the physical filing process totally. Additionally, not all things are right now accessible in the e-filing framework and for some extraordinary situations the candidates need to embrace request for physically at the Indian patent office.

4. Hire a patent agent or do it by yourself

Now, you have selected the mode of patent filing in India, the following vital thing to ask is whether you wish to plan and document a patent application yourself or contract a patent firm with experienced agents or lawyers. Be that as it may, it is absolutely prudent to contract a patent professional to help you with the patent documenting and process till the grant of the patent. The advantage of contracting a patent agent

4.1 Superior nature of the patent application

The center of a patent application is the patent specification which contains the revelation about the development and is composed in a techno-legal way. The details of the patent application require some serious energy and must be done in a way to guarantee that you can benefit from the patent. The specifications are the determining factors of a patent, particularly the claims. Therefore, drafting it yourself might lose some point and can cause trouble in your business.

4.2 keeping in check the deadline by a professional

Overseeing the due dates may appear like a basic assignment but in real it is not, missing a patent due date can be very critical and cause lots of trouble. Consider a case where you have documented another patent application. In case you are considering filing application in foreign countries, you get a year from your priority date to document applications. Assume you consider to document patent applications in different nations after 2 years and don’t know about the year due date, you will be baffled to take note of that the alternative of documenting in outside nations is lost and you have for all intents and purposes given out your conceivable patent rights in these nations for nothing.

In another illustration, suppose that you have documented another patent application in India. You are required to make a request for examination within four years from the priority. In the event that you neglect to recollect this due date and don’t record the request for examination within the required time, your patent application will be abandoned and can’t be filed again.

4.3 Not walking upon others

Another advantage of having a patent professional is to guarantee that you or your organization isn’t damaging patent privileges of other parties. The main motive to document patents is to ensure your invention protection yet there can be instances where the organization might overlap other parties’ invention. Thus, consider every option in the event that you can take such risks with your patent application.

5. Dialect, paper estimate, text styles for patent recording in India

India allows the candidate to fill the application form in either English or Hindi. However, larger parts of patent filings done in India are in English but, do not lose hope, the patent office has assigned inspectors who can look at the applications in Hindi also.

In case, a patent application is documented in another nation in that patent office’s preferred language and a relating application is documented in India (either through the Paris Convention or the PCT), an interpretation would be required to be given in both of the official languages in India.
