技術標準化與相關智慧財產權保護，一直以來為智慧財產權法與競爭法的交集與爭議的話題。其中又以標準必要專利侵權糾紛為主。基於標準必要專利權人與前在被授權人雙方的立場，其中目前最具爭議的問題應該涉及禁制令救濟的適用性或以F/RAND授權原則為基礎的抗辯來排除侵權。 標準制訂組織（Standard Setting Organization, SSO）訂定F/RAND授權原則承諾（Fair, Reasonable And Non-Discriminatory）於其智慧財產權政策，要求標準專利權人應以公平、合理且無歧視的授權條件，向所有標準實施者提供授權。F/RAND授權原則承諾之發展，目前趨向於強調專利權人的契約義務，以第三方受益人的立場來平衡授權當事人的談判地位；如何「符合F/RAND授權原則之授權」，目前各國尚未有明文法律解釋，對於F/RAND授權原則承諾之清楚定義與規範，目前僅有法院及競爭法主管機關之見解。 在標準必要專利訴訟中，台灣廠商處於被告之身分的狀況居多。面對禁制令的威脅，如何更清楚地了解目前各管轄法院的看法以決定訴訟或談判策略更是重要。本文整理美國、歐洲及亞洲國家之管轄法院案例，加上對競爭法架構下的標準專利授權規範的分析，最後整理如何讓F/RAND授權原則承諾成為對抗禁制令有效抗辯。希望本文能為涉及標準專利訴訟之台灣廠商提供有價值的參考意見。 / Technology standardization and intellectual property protection has been an overlapping and controversial issue between Intellectual Property laws and Competition Law, particularly when it comes to infringement on F/RAND encumbered Standard Essential Patent, SEP. From both standard essential patent owner and potential licensee’ perspectives, the most questionable issue is whether injunctive relief should be available to the holder of F/RAND encumbered SEP who committed to license on fair, reasonable and non-discriminatory (F/RAND) terms, in order to prevent a third-party implementer from practicing a standard reading on that SEP, when such implementer is willing to take a license but the parties disagree on the terms of the license. Furthermore, the definition of F/RAND has never been clearly defined by statutes or interpreted by any judiciary; interested parties could only refer to decisions or guidelines made by the judiciaries or competition authorities in different countries. It is rather common for Taiwanese companies to face F/RAND encumbered SEP law suits as the defendants. Given the even severer threat of injunctive relief, it becomes more important to understand the position each judiciary takes on this issue to have appropriate strategies on law suits and negotiation. This thesis is accordingly written on the following perspectives: firstly, starting with discussion about F/RAND-encumbered SEP law suits in the United States, Europe and Asia; secondly, bringing in SEP encumbered disputes or investigations into framework of Competition Law from competition authorities among different countries and lastly trying to present possibilities that F/RAND commitment as a cause of action under Contract Law can be applied as defense to overcome injunctive relief sought by F/RAND-encumbered SEP licensors. Meanwhile, this thesis is expected to provide Taiwanese companies valuable strategies to law suits or disputes involving F/RAND-encumbered SEPs.
