in 2007, the two terms "tai-ke" and "tai-ke rock" was registered as a trademark by neutron innovation (bvi) ltd who held the rock concert. they received the permission from roc ministry of economic affairs intellectual property office. this caused the east coast hot rock festival which was supposed to be held in hualien on august 4, with the theme "taike rock night" to be forced to be renamed into "east coast rock night." this incident aroused cultural dissatisfaction and questions from the academic circles. ltk commune's lead singer, ko ren-chien as well as legislator lin shu-fen openly opposed the word "tai-ke" to be registered as a trademark. the neutron innovative companies sponsored its first rock carnival "eliminate stigma of tai-ke" to appeal to the community to maintain respect for their brand value; but because such a cultural expression was registered as a trademark, it created great controversy. in 10 september 2007, ceo zhang peiren of the neutron innovation company, announced that the company will abandon the "tai-ke" trademark and will consider cancelling their subsequent rock concert. consequently, taiwanese singer, chang chen-yue who has previously performed in the rock concerts held by neutron innovation ltd expressed his displeasure. he felt that "previously, nobody cared about the tai-ke culture. it was the rock concerts that advocated it. those politicians and scholars did not support us and even looked at us with discrimination. however, now that tai-ke gained popularity they rose up against our trademark. it is very unreasonable."
