You can apply yourself or take help of Patent Attorney. See resources at http://www.indianinnovatorsforum.org/patent_registration.htm Before you apply for patent, read `Fundamentals of Patenting’. TePP has provision to support patenting but to disclose the details, innovators are advised to apply for provisional patent before applying to TePP.

In most cases, students develop models with institute resources and participate in competitions. Where institution support is not available, then student innovator can apply for grant under TS category of TePP. http://www.indianinnovatorsforum.org/patent_registration.htm If it is embedded product, students can make models using demo boards of TI and others.

Developing a function providing prototype calls for expenditure, often beyond the reach of students. They can seek support under TPF. However, working on large projects is a full time activity and students are encouraged to apply under TPF after completing studies. Before you apply, take the self test http://www.dsir.gov.in/tpdup/tepp/tepp_checklist.htm Rapid Prototyping services are available at several institutes like CMERI and design houses. It is economical and faster to use RP tools at concept proving stage. See web site of 3DPD http://www.3dpd.net/

TePP supports student teams participating in international competitions. Write to TePP with details.
