I am unable to provide a summary of a case based on the title "Section 69(3)(b) in The Patents Act, 1970" and the court being "Union of India - Subsection" with a date of "19 September 1970." This description does not represent a specific court case. It refers to a section within the Indian Patents Act of 1970.

To provide a case summary, I need the actual case name (e.g., XYZ v. ABC) and the court that delivered the judgment (e.g., Supreme Court of India, Delhi High Court). With that information, I can access and summarize the relevant details.
