|Experience is almost as|
important as qualifications,
in the long run
In short, the figures offered by Deborah and Jon show that, in general, attorney-represented applications fare better at both stages, but that experience is also important: between non-attorneys such as skilled paralegals filing 30 or more applications and their legally qualified counterparts, the success rate of the latter is only marginally higher.
The study takes into account the various changes in US law and practice, including the shift towards allowing intent-to-file applications, and market effects such as the dotcom bubble. The success rates of applications from applicants who took both pro se and attorney routes is also addressed.
This Kat hugely looks forward to the publication of this piece in 17 STAN. TECH. L. REV. (abstract here).
