Executive Summary
The appellant challenged the denial of his plea for extending the validity/tenure of his Patent due to seven-year delays by authorities. He also questioned the constitutional validity of Section 53 of the Patents Act, 1970. The Calcutta High Court upheld the Single Judge's decision, stating that no provision allows for automatic extension as a penalty and noting that the issue of constitutional validity was not properly argued.
