How to measure patent thickets – a novel approach [PDF]

open access: yes, 2009
The existing literature identifies patent thickets indirectly. In this paper we propose a novel measure based on patent citations which allows us to measure the density of patent thickets directly. We discuss the algorithm which generates the measure and

The Effect of Quadrature Errors in the Computation of L^2 Piecewise Polynomial Approximations [PDF]

open access: yes, 1976
In this paper we investigate the L^2 piecewise polynomial approximation problem. L^2 bounds for the derivatives of the error in approximating sufficiently smooth functions by polynomial splines follow immediately from the analogous results for polynomial

Patent Value and Survival of Patents [PDF]

open access: yesJournal of Open Innovation: Technology, Market, and Complexity, 2021
This study investigated the effect of patent value on the renewal (survival) of patents. The private value of patents can be one of the main pillars sustaining a firm’s value, and the estimation of the value may contribute to the strategic management of firms.

Standards, Innovation Incentives, and the Formation of Patent Pools [PDF]

open access: yes, 2010
Technological standards give rise to a complements problem that affects pricing and innovation incentives of technology producers. In this paper I discuss how patent pools can be used to solve these problems and what incentives patent holders have to ...

Integral Representations of Cooperative Game with Fuzzy Coalitions

open access: yesJournal of Applied Mathematics, 2014
Classical extensions of fuzzy game models are based on various integrals, such as Butnariu game and Tsurumi game. A new class of symmetric extension of fuzzy game with fuzzy coalition variables is put forward with Concave integral, where players ...
