In this article, from the perspective of analyzing European Union law and Vietnamese law on patent registration as well as the practical examination of patent applications in the European Union and Vietnam in which proposes experience for Vietnam in the process of completing, amending, and supplementing legal regulations related to the process and methods of examining patent applications to save time on granting patents as well as protect industrial rights of the applicant. As a matter of practice, the long process of examining industrial property applications in general and patents, in particular, has caused difficulties for the rights holder in the process of intellectual property exploitation while the cycle of development of alternative technology or, in other words, the life cycle of technology is getting shorter and shorter. In this regard, the right holders only have a few years even a couple of months from the application date to start the process of commercial exploitation so that the right holders are unable to recover the expense of the investment for developing inventions. Besides, the number of patent applications is increasing along with economic development and national start-up campaigns. Therefore, in the context of shortening patent examination and other industrial property, in general, are now significantly necessary. Furthermore, within the scope of the article, the authors have compared the regulations of the European Patent Convention regarding the patent application examination, despite the similar steps of filing compared to Vietnam’s regulations, the European Patent Convention still has some significant regulations to shorten the examination. As the result, based on reference to EU regulations, the authors propose a number of solutions to overcome the situations leading to the prolongation of the patent granting time and effectively protecting the interests of the applicant in Vietnam.
