To make myself clear, I am interested in working as an IP lawyer in an international organization (law firms, MNCs, international bodies, etc).

I have done my LLB from a Non-NLU government university in India , and I want my LLM to be from a reputed institution. Please guide me if possible.

Anything by RGSOIPL (IIT).
An overwhelming number of faculty is absolutely not worth writing home about.
Their research output is ...

The other person has given a good list for ex-India.
For India, I would say, take a decent LLM + supplant it with internships so that Companies/ Firms find you immediately employable at end of LLM.

I don’t wish to dox myself, but let’s just say that I am eminently qualified to answer your question. Here’s my assessment:

First of all, understand that sometimes law schools with a lower overall ranking may be better for certain specialist courses. For example, say Fordham or GW over Chicago. But if you are obsessed with rankings then just blindly go for the top ones. But employers are more discerning and not obsessed with rankings like in India.

Second, understand that employers in India are not concerned about LLM degrees. In Europe, yes. In China, yes. In Brazil, yes. Not India.

With these two caveats, here are my views….

US: Tons of good law schools with good IP profs, but you might want to pick a law school where there is a large cohort of good IP profs and research centres. The US News IPR ranking are a pretty good indicator. Again, you will note here that many of the law scholars listed are not super-prestigious.

UK: London colleges like KCL/QM/UCL tend to offer specialist IP modules with an emphasis on practical knowledge, whereas Oxbridge is a bit more theoretical and abstract. Whatever works for you. Oxford does offer a very nice IP programme for those wishing to practice, but unfortunately it’s a diploma and not a degree like the BCL. A diploma is not given weightage by Indian employers.

EU: CEIPI, MIPLC, Turin (WIPO),Stockholm are good, safe choices. You could look at Leuven, Amsterdam and Tilburg too, but only as a second option IMO, for various reasons too lengthy to mention here (but they are still good).

Australia: Melbourne, UNSW and Sydney are good choices, but a bit theoretical.

India: NLSIU has good faculty. Jindal and NLUD used to have good IP faculty but most have left.

Ha ing worked with the two of them, I'd say both of them are good. Yogesh also has good publications like Arul. They worked well in a centre with opposing ideologies, Yogesh being pro IP and Arul being not so pro IP.

And there are teachers like Shubha Ghosh and Watal in that program as well, so how bad could it be.

I would say Jindal because it gives comparatively more attention to LLM students than NLUs, where students, faculty and admin all treat LLM students like sh*t. In fact, at NLSIU there was anger at the suggestion that LLM alumni should be allowed to attend alumni networking meets alongside BALLB alumni.. Also, you get more freedom in terms of campus timings and discipline.

So for this reason I would say Jindal over NLUs, including NLSIU.

There's one faculty there who has got a monologue published in Elgar Encyclopedia of IP. Niharika Salar I think
