Palangkaraya, A., Jensen, P.H. and Webster, E. (2008). “Applicant behavior in patent examination request lags”, Economics Letters 101, 243-45.
One component of the duration of pending patents – why applicants choose to delay the examination process – is modelled. We use a matched sample of 9597 patent applications to examine this issue. Controlling for differences between patent offices, we find evidence that applicants create investment uncertainty by delaying decisions to request patent examination.
