Patent Oppositions and Limited Citations as Anti-Competitve Behavoir?

According to "The Influence of Strategic Patenting on Companies’ Patent Portfolios" by Knut Blind, Katrin Cremers, and Elisabeth Mueller,

. . . the phenomenon of frequent oppositions and rather limited citations in a company's patent portfolio is an incidence that the company is implementing an offensive blocking strategy and thus misusing the patent system. This is a potential information source, which could be used in investigations of anti-competitive behaviour in specific markets or by single companies. In summary, this investigation has confirmed the validity and the usability of patent portfolio characteristics not only for innovation management, but also policy issues.
