“…Non-standard functions of patents, in general, hardly facilitate productive entrepreneurship, and often only serve rent-seeking. On the basis of an extensive literature review [cf., e.g., Langinier, 2005;Penin, 2005;Blind et al, 2006;2009;Chien, 2008;Noel, Schankerman, 2013;Grossmann et al, 2016;Förster, 2017;Holgersson, Granstrand, 2017], the following non-standard functions of patents can be distinguished: to block rivals, to use patents to increase someone's bargaining power in negotiations with potential business partners, to exploit a competitive advantage over rivals, to protect an enterprise's share in the domestic or international market, to increase the operating costs of the enterprise's rivals, to raise barriers to market entry, to mislead the enterprise's rivals in the patent race, and to force other enterprises to bear the expenses of a legal dispute over patent violation (patent predation strategy).…”
