In this study, with revenue in the global ranking the Top 15 and Taiwan′s main fabless IC design companies as the research objects. Collected US issued patents from 2001 to 2002 and applied ordered probit model analysis model. Empirical research conducted in three stages: patent characteristics and patent maintenance association analysis, the US manufacturers and other countries for patent maintenance analysis, litigating patent for patent maintenance association analysis.
It was found that there are significant number of patents to maintain a positive association of explanatory variables are: the number of patent citations, the number of patents cited, technical scope, the present study suggests that the more cited literature indicates invention discloses the book will be more comprehensive and tight, if approved by the audit committee of issuance, the patent should have considerable value. Patents are cited more times, indicating that the patent should be valuable core technology, empirical findings that these patents are indeed relatively maintenance number of times. The technology covered by the patent belongs more items, with an annual fee to maintain the number of positively interlocking relationship, confirms patent coverage more widely, the higher the value.
Patent maintenance times does not have significant positive correlation between the explanatory variables are: the number of inventors, the number of patentee, the number of claims. The number of inventors over the last little literature explanatory variables included in the invention, the initial purpose of this study think brainstorm via multiple inventors will have a well-conceived creative, but the inventors have found that the number of the empirical value of the measure for the patent is not suitable the explanatory variables, mainly the more the number of inventors, patent value does not increase proportionally. Moreover, there may be moral hazard problem, and can not play more than brainstorming benefits between inventors . And between the patentee, it may be due to have different core technologies to accelerate the development program and strategic alliances or technology licensing, in order to avoid duplication of investment in the waste, due to the results of joint research attributable to both parties (constituents, even multi-) holds in the present study, the number of samples in the ownership of more than one patentee is too small, so the number of patents to maintain relevance not significant.
Litigating patent in this study has a positive, but not significant correlation, but if the 28 litigating patents maintenance frequency statistics, up to 96.43% of the patent is to pay the entire period (3 times) the maintenance fees, to show the litigating patents have high value. |
