IP-Managers do often consider if IP-protection is the only "true way" of satisfying the needs of their companies. It is correct, that IP-protection for Patents, Designs and Trademarks are useful to improve the position of companies in the market. However those IP-rights provide only a right to stop others doing businesses in the protected areas. These rights - at least fromtheir filing days do not protect the companies from being attacked by foreign IP-rights. That means that IP-rights can only be used for a defense against competitors in a limited manner. Here Defensive Publications fill an important gap and at the same time ensure that inventors will not be taken by surprise through late comers in the same field.
