Dispute Summary
The appellant filed an application for a patent relating to solid lobular Aluminium Chloride produced via desublimation. The Controller objected that the invention was not patentable under Section 5(b) because it involved a chemical process. The Calcutta High Court upheld this objection, ruling that since the substance is obtained through a larger chemical manufacturing process (chlorination of alumina), the final physical step of desublimation cannot be considered separately for patentability.
