LED照明技术与应用市场的发展有着极其紧密地联繫，技术的发展程度制约着应用市场的拓展，同样应用市场的变化也影响着技术的发展和转移方式，LED专利授权及纠纷等专利事件的变化就明确反映出了这种联繫。随着LED照明产品开发和应用范围不断扩大，更多公司拥有了相关专利，特别是随着半导体照明应用产品种类和生产厂商越来越多、市场规模急剧扩大，专利关係也越来越复杂。在这种形势下，怎样保证一个公司的产品不会侵犯其他公司的专利权就是一个迫切需要解决的问题。从法律角度来看，单纯听信卖方的承诺显然不够，极有可能要冒侵权的风险；聘请专利律师进行调查可以解决这个问题，但要花费大量的时间和资金，并不是每个企业都有能力采用，所以建立正确的专利权知识，以及设法取得产品相关的专利权资讯，是现阶段市场成长期间的重要课题之一。
