專利分析對於專利布局而言是相當重要的事前調查，原因在於分析特定技術領域的專利趨勢，企業可以審視欲申請專利的新穎性；而說明書撰稿人則可以衡量一發明是否符合進步性要求。對企業體每一項產品的研發都所費不貲，當然會利用專利保護自己的技術創意，更重要的是，一旦產品上市卻遭到專利侵權訴訟的延宕，對於企業的形象、經營都是極大的打擊，因此事前調查對於欲推出產品相關領域的專利概況尤其重要。
以目前台灣的電子產業來說，近來專利訴訟不斷，突顯了企業體在專利方面事前準備的不足，但對於幾乎是三個月一世代的電子產業、各企業皆持有專利數量龐大的情形下，專利地圖製作起來相當費時費力而且需要大量人力，經常令人難以決定是否有進行的必要。
專利趨勢分析可以提供前期資訊，幫助決定是否在特定專利群中，逐一定義個別專利所揭露的技術，及其所達成的功效。趨勢分析結合技術及市場資訊更可以揭露一個技術領域中技術發展的概況、對手企業動向，以提供企業技術研發及市場經營的方向。
本研究以金屬氧化物電阻式記憶體為例，提出一種適用於電子產業的調查方式，便於對於專利趨勢與具影響力的專利本身快速評估，具體方式則是以產業環節做為觀點的產業鏈方式進行專利分析，並且與以引證數量作為指標的傳統方式進行比較。就方法論而言，本研究提出的專利趨勢分析流程特色在於快速、簡單、而且步驟明確，更重要的是本研究以專利分類號作為主軸，可以大幅降低在進行專利趨勢分析時對於人力技術背景的要求。

For patent strategy, patent analysis is a very important pre-investigation. Based on the analysis to the trend of a specific field, the enterprise can examine the novelty of an invention to be applied for patent; the patent drafter can weigh the inventive steps of the application. The development of each product costs a lot to every enterprise, and therefore it is nature to seek patent protection. The most important, once the product of an enterprise involved in litigation, it is a serious damage to the enterprise regarding the enterprise image and operation. Thus pre-investigating to the circumstance of the field related to the product being marketed is necessary.
In Taiwan electronics industry, patent litigation takes place all the time currently. That news highlights that the Taiwan enterprises neglect the aspect of patent in advance. However electronics industry varies circumstance every 3 month and most enterprises hold numerous patents. The necessity is doubtable to spend tremendous time and human resource to construct a patent map.
The trend analysis of patent provides the preliminary information and facilitates the decision of whether it is necessary to construct a patent map. Combining the technology and market information, the trend analysis even can disclose the technical development profile and the tendency of competitors to provide the direction of research and marketing for enterprises.
This study uses the metal oxide resistive random-access-memory as example and provides the investigation method suitable for electronics industry. It is convenient to estimate the patent tendency and the influence of a patent itself. This analysis method takes the point of view of industry chain. The result of this method is validated through comparing with the properties of the patents selected by citation. In the aspect of methodology, this study provides an analysis process for electronics patent tendency. Its characters are fast, simple and step-defined. More important, the analysis is based on patent classification number. That could dramatically decrease the technology requirement of human resource when proceeding to the patent tendency analysis.
