As of today, I have collected more than 50 research surveys by law firms. Of the 24 firms represented in that collection, 19 of them appear to have conducted one-shot surveys. They may have conducted more than one survey, but only a single year for any topic. Outsiders have no way of figuring out why the firm chose not to follow a survey with another and thereby start identifying trends and building a brand for the survey.
On the other hand, at least four firms have continued a string of surveys on the same topic through 2017. One firm continued a long series but discontinued it five years ago.
Fulbright & Jaworski began its annual survey of litigation in 2004. The firm merged and is now Norton Rose Fulbright, but it kept up its survey effort through 2017, an astonishing 14 years.
Carlton Fields Jordan Burt began a survey focused on class action litigation in 2012 and has done six annual versions since then.
Littler Mendelson runs a survey focused on the views of executive employers. Begun in 2012, the survey streak has reached the six-year mark.
For the past three years, Haynes and Boone has conducted its twice yearly survey of borrowing base determinations. Even though that constitutes six surveys, the firm has three years under its belt for this reckoning.
Proskauer’s inaugural survey regarding employment issues appeared in 2016 and the firm returned to survey the same topic in 2017.
Another noteworthy streak appears to have ended five years ago. Davies Ward Phillips teamed with the Canadian Corporate Counsel Association (CCCA) in 2005 for a study of Canadian in-house counsel, called the Barometer. I did some online research and believe the series continued eight years until 2012.
