Valuating and analyzing the patent portfolio: the patent portfolio value index

Abstract

Purpose: The purpose of the paper is to advance a framework that can assess and analyze the value of patent portfolios. On this purpose, the framework develops a conceptual and comprehensive index, the patent portfolio value index (PPVI), to assess the patent innovation level and suggest economic-strategic guidelines. Design/methodology/approach: The authors have designed and applied a framework that synthesizes into a single index the results of a multiple criteria approach, based on information derived from quantitative objective data (claims, citations, and market coverage), information related to qualitative determinants (strategic positioning and economic importance), and information derived from decision makers’ perceptions and judgments. Findings: The authors have applied the PPVI to the 3,532 patent portfolio documents in an Italian worldwide player in aerospace and defense market. The combined analysis, provided by the PPVI and a qualitative synoptic representation, has made it possible to understand the strategic positioning and alignment of patents with the core business of the company. The results of the analysis have provided managers with the necessary suggestions regarding action items to be performed: to reinforce, license, try to dismiss, or sell some of the examined patents of the portfolios. Practical implications: The PPVI supplies a quick procedure to ascertain the profitability of patents and accounts for the value of a patent portfolio from an internal business perspective. Originality/value: As it is built and defined, the PPVI shows elements of novelty compared to the other indexes existing in the literature, in that it follows a multiple criteria approach by merging quantitative and qualitative information.
