Section 35 (2ab) - 200% weighted deduction

Yes you can avail deduction u/s 35(2AB) since it states that "any" expenditure shall be allowed in the case of companies engaged in business of bio-technology and approved by pescribed authority.

Provided deduction for purchase of land is not allowed and for building its limited to 100% of cost.

But as per guidelines published by DSIR (prescribed authority) on May 2014. Capital expenditure on R&D, eligible for weighted deduction will include only plant and equipment or any other tangible item. Capitalized expenditure of intangible nature will not be eligible for weighted deduction. In our case we are not purchase any intangible asset but we are generating by internal projects and same we are filling for patents. Can we claim the same.
