In an important decision, the deputy commissioner of patents recently ruled that late national stage entry of a patent application will not be approved without a reason for the delay.
The deputy commissioner ruled that since the standard for allowing a late application enter the national stage is “due care”, this standard must be met. “Due care” includes, as a very first and basic step, finding out what the deadline is.
However, the interesting part of the decision is not the (expected) rejection of the petition, but rather the examples that the deputy commissioner brought to cases when such a petition will be allowed.
One such a case is when the applicant simply confused Israel (IL) with Iceland (IS). In such a case, the applicant did try to find out the date, but made an understandable mistake and hence, a petition for late entry of the national stage will be allowed.
Another case is a case when an applicant mistakenly thought that Sunday is a day off in Israel, like in most of the world, and filed the application on the Monday thereafter.
