[Article/Patents] What Does “So as to Enable Use” in the Enablement Requirement Mean? (Atsushi Nagano, Intellectual Property Management, Vol. 74, No. 11, 2024)
Court decisions are divided on whether “so as to enable use” under the enablement requirement should be construed to mean enabling use in a manner that solves the problem addressed by the invention.
Example 11 in the Examination Handbook adopts the view that the functions and effects need not be achieved.
Looking at decisions from 2010 through 2024, 27 adopt the view that functions and effects are not required, while 15 require them.
*However, many decisions adopting the view that functions and effects are required ultimately found the enablement requirement satisfied, and some decisions adopting the view that functions and effects are necessary found a violation of the support requirement. Thus, this issue was decisive to the ultimate patentability outcome in relatively few cases.
Translator’s notes (editorial)
The source repeats the view requiring functions and effects in the final two comparisons; that wording is preserved rather than changed to the contrary view.
