How to draft a patent application

A new invention needs protection and that protection has a process. As and when you discover an invention, you have to see which type of protection should we give to the invention and accordingly the patent application is prepared.

There are various intellectual properties such as trademark, patent, copyright, trade secret, etc. In case, you come on to the conclusion that your invention needs protection, you may start preparing the application.  

Determine if the invention is patentable 

Preparing a patent application is more difficult and time-consuming than one may think. Once you know the type of intellectual property you need and decided that you want patent protection. It is important to determine if the invention is patentable. For that, we conduct a prior-art search.  

Conduct a prior-art search to gather information about the prior arts that may be present already. They may be similar to your search and thus making your invention old. This can lead to infringement later on. So, your invention must not be publicly disclosed already. If you are not experienced in conducting prior art search then it is recommended to hire a licensed patent attorney or agent.

Range of protection: You can patent your invention in more than one country. So, you have to decide if you need international protection and draft accordingly for different countries where you need protection. 

Hiring a patent attorney or doing it yourself: It is although recommended to hire an attorney, you yourself can also draft your application. Preparing an patent application is a large process and requires wide knowledge for different steps of drafting and the inventor needs to have knowledge in all these areas.
