series Love Hina and Mahou Sensei Negima!, expressed concern the agreement could decimate the derivative dōjinshi (self-published) works prevalent in Japan. Akamatsu argued that the TPP "would destroy derivative dōjinshi. And as a result, the power of the entire manga industry would also diminish." Pharmaceuticals In May 2015, Nobel Memorial prize winning economist Paul Krugman expressed concern that the TPP would tighten the patent laws and allow corporations such as big pharmaceutical companies and Hollywood to gain advantages, in terms of increasing rewards, at the cost of consumers, and that people in developing countries would not be able to access the medicines under the TPP regime. However, Walter Park, Professor of Economics at American University, argues that it is far from clear in economic research that this would necessarily happen: clarifying intellectual property rights on drugs, for some developing countries, has not led to greater prices and less access to drugs. Park also argues, based on the existing literature, that the pharmaceutical protections in TPP will potentially enhance unaffiliated licensing in developing countries, lead to tech transfers that contribute to local learning-by-doing, stimulate new drug launches in more countries, expand marketing and distribution networks, and encourage early stage pharmaceutical innovations. The Office of the United States Trade Representative notes that the TPP "aligns with the Doha Declaration on TRIPS and Public Health", which allows developing countries to circumvent patent rights for better access to essential medicines. Pharmaceutical companies have criticized TPP for having too lenient intellectual property protections. In July 2015, an editorial in the New England Journal of Medicine cited concerns by Médecins sans Frontières and Oxfam that a spike in drug prices caused by patent extensions could threaten millions of lives. Extending "data exclusivity" provisions would "prevent drug regulatory agencies such as the Food and Drug Administration from registering a generic version of a drug for a certain number of years." The article arugues that TPP could theoretically require corporations be paid compensation for any "lost profits" found to result from a nation's health regulations. The article argues that the provisions in the TPP concerning generic drugs directly target India's pharmaceutical industry. Doctors Without Borders said in November 2015 that it was "extremely concerned about the inclusion of dangerous provisions that would dismantle public health safeguards enshrined in international law and restrict access to price-lowering generic medicines for millions of people."
