Basically, right over a Trade Mark can be acquired by two modes. a)By registration under the Trade Marks Act and b) By usage. The REgistered proprietor of the mark has the protection under the provisions of Trade Marks Act and the unregistered user can protect his right under the common law.
In the present case as the Degree college is the prior adopter of the mark and started using since 2002, the priority of use is on their side. Apparently they are the prior adopters and not the infringers of your mark. Hope u may not suceed initiating matter filing infringement action.
Further, Srinidhi is a common word used in India and may not suceed in protecting the right over it.
Hope this clarifies your query.
