Though coined long back, IPR in India is gaining much attention and significance these days. So far as Patent is concerned the scope is very wide. To practise in the field of patent, you can opt for any course either LL.M., or any Diploma Course or Test for Patent Attorney.
If you choose to be a patent practitioner, then I would suggest you to go for anything except LL.M., because, your focus will get diverted on getting good result instead of understanding the practical aspects. you need to give alot time for reading. There is no ready material or reference books available at one library. you will have to hunt alot for gathering the material from here n there, google search, etc.
Ya but if you want to go in teaching line, then it is must. So far as the practise is concerned, knowledge makes man perfect, start reading anything realting to IPR. you can learn the basics from different sites viz. WIPO, WTO, https://www.tmpsearchers.com, etc. Also go through various convention of IP, read case laws of IP.
I think this will help you.
