Professor Stephen Haber of Stanford, Professor Alexander Galetovic of the Universidad de los Andes in Chile and Lew Zaretski, the head of IP strategy firm Hamilton IPV have released a new study on the licensing revenues of 32 major licensors to the mobile sector.

They show that the royalty stake is likely to amount 3,3% of the total value of the smartphone and feature phone markets in 2015.

The authors make clear that they are not taking a position on the level of the royalty rate, the trio is clearly trying to prove that the concern that patent owners are subjecting the likes of Apple and Samsung to unduly high licensing rates is unfounded.

The study is available here.
